Description

Description: TECHNICAL FIELD The present invention relates to an image processing apparatus for processing an image, and particularly to an electronic processing apparatus for drawing figures on paper using various pens as writing instruments. The present invention relates to an image processing apparatus capable of editing an image using a pen.

[Prior Art] Drawing is performed using a Japanese word processor or a computer, and this is used in the field of design or combined with a part of a document. In this type of image processing apparatus, a figure is created by designating the type of figure such as a circle or a triangle, or by designating the locus of a curve using a pointing device such as a mouse. The type of line as a component of the figure is determined by selecting a desired one from several types of solid lines and broken lines set in advance.

In such an image processing apparatus, the thickness of the line cannot be finely adjusted, and therefore the image to be expressed has to be a uniform one with a small degree of freedom. Recently, various types of images can be read by the device using an image sensor such as a CCD, and the images can be edited.In this connection, more flexibility in creating lines and points is provided. The emergence of effective figure creation means has been desired.

Therefore, an image processing apparatus capable of editing an image using an electronic pen has been devised so that an image can be freely expressed on paper by using a fountain pen, a crayon, or a paint brush. I have.

In this image processing apparatus, an electronic pen having a pen tip having a predetermined bit pattern is prepared, and an image is created as if drawing a picture. The pen point is, for example, 27th
As shown in the figure, it has a pattern configuration of 7 × 7 pixels. As an example, as shown in FIG. 28, if a straight line is drawn using a pen tip in which only one of the pixels is “black” (printed), all the pixels shown in FIG. The thickness of the line can be extremely thin compared to the case where a straight line is drawn with the pen tip. If the pen is moved in the horizontal direction in the figure using a pen tip where "black" is separated into two parts as shown in FIG. 30, two lines having the shape as shown in FIG. 31 are drawn. If it is moved in the vertical direction, one straight line can be drawn as shown in FIG.

In the case of the pen tip shown in Fig. 30, if it is rotated 90 degrees and moved in the horizontal direction, the same straight line as in Fig. 32 can be reproduced, for example, rotated 45 degrees and moved in the horizontal direction If this is done, a different line representation will be possible, as shown in FIG. If the angle is changed to another angle or the direction of movement of the pen tip is changed, various different figures can be similarly drawn. In this image processing apparatus, it is also possible to draw a figure by appropriately enlarging the pen tip.

"Problems to be Solved by the Invention" As described above, the image processing apparatus of the present invention performs image processing using an electronic pen capable of freely setting the shape and size of the pen tip. I have. With conventional image processing devices, the thickness of lines used when creating figures etc. was only a few types, so even if it is limited to the thickness of lines that can be expressed, this new inventor has quite free image processing It turns out that it becomes possible.

However, the image processing apparatus of the present invention has a problem that it is difficult to specify the use state of the pen tip as an adverse effect of being able to freely set and use the thickness and shape of the pen tip. .

For example, after drawing a line segment with the pen tip set to a certain size, even if you try to extend this line segment at a later date, it is difficult to use the pen tip in the same usage condition as before, Sometimes the thickness was out of order by a few pixels.
Also, even if the shape of the joint between the original figure and the newly added figure is continuous, a different pattern from the previous pattern in the same state may be reproduced depending on the direction in which the pen moves. Was.

In view of the above, an object of the present invention is to provide an image processing apparatus capable of expressing the state of a pen tip or the like with data such as numerical values and easily setting a pen to a desired use state.

"Means for solving the problem" In the present invention, in the image processing apparatus that selects a bit pattern as a registered pen tip, and draws a graphic by moving the selected bit pattern on the display screen, (A) a storage means for storing information on a bit pattern as a pen tip, and (b) a position as a pen tip center based on information for specifying a center position at which the pen tip is moved or rotated. Editing means for editing the bit pattern data whose position as the pen point center has been changed; and (c) converting the bit pattern data as an editing result of the editing means into a predetermined value for the bit pattern data. Registering means for registering these in the storage means in association with size information including a numerical value of a unit, and (d) desired image data Cutting means for cutting a specified area as the input data,
(E) The image editing apparatus is provided with size display means for displaying size information on the bit pattern data on the display screen at least during selection and editing.

As described above, according to the present invention, it is possible to change the center position which is the center when the pen tip is moved or rotated with respect to the bit pattern as the pen tip obtained by cutting out the designated area of the desired image data. On the other hand, the bit pattern data as an editing result of the editing means for performing the change or the like can be registered in the storage means together with size information including a numerical value of a predetermined unit relating to the bit pattern data, and can be selected as the bit pattern of the pen tip. Like that. Then, at least one of when the bit pattern is selected or registered in the storage means, size information on the corresponding bit pattern is displayed, so that the pen tip can be easily set to a desired use state.

Although the pen tip used in the image processing apparatus of the present invention is composed of a predetermined bit pattern, it is not always necessary to use a pattern created for the pen tip. It is also possible to use as.

"Example" Hereinafter, the present invention will be described in detail with reference to examples.

FIG. 1 shows a main part of a circuit configuration of an image processing apparatus according to an embodiment of the present invention.

The image processing apparatus includes a CPU (central processing unit) 11 and is connected to each part of the apparatus by a bus 12. The RAM 13 is a random access memory for temporarily storing various data. The pen tip pattern storage unit 14 is a memory in which various pen tips are registered. The pen tip data storage unit 15 is a memory for temporarily storing data on the pen tip to be used. The program storage unit 16 is a memory that stores various programs for controlling the operation of the image processing apparatus. The display control device 17 is a device for controlling display on the display 18 and includes a display RAM for storing an image in a bit pattern. Mouse 19 is a pointing device,
When this is moved on a desk, the cursor can be moved to a desired position. Two buttons are arranged on the mouse 19, and various instructions can be given by pressing (pressing) these buttons. The keyboard 20 is provided with various keys such as a numeric keypad. By operating these keys, it is possible to input text and various instructions to the image processing apparatus.

Types of Pens The types of pens used by the image processing apparatus having the above configuration will be described.

The following three types of pens can be used in the image processing apparatus of this embodiment.

(1) System registration pen This pen is provided in advance by the device side. These are seven types of black-painted figures having different sizes as shown in FIG.

(2) User-registered pen This pen creates and registers a pen tip pattern according to the user's preference.

(3) Cut-off pen A pen that has a pen tip formed by cutting off a part of an image created already or a part of the screen. Although the system registration pen and the user registration pen are limited in the number of pixels (pen tip size) constituting one pen, in the case of the cutout pen, there is practically no restriction on this.

When the operator sets the image processing apparatus in the image editing mode, a window called a palette window is displayed on a part of the display 18. The operator can use this window and mouse 19 to
It is possible to freely draw figures and pictures in an image creation area (campus) set on the display 18.

FIG. 3 illustrates the operation of selecting the three types of pens in this state. When the operator selects a pen mark from the several marks displayed in the palette window with the mouse 19 (step), a small window called a pen pop-up menu is displayed on a part of the display 18 (step). When a mark other than the pen mark is selected or other work is performed, processing corresponding to the operation is performed (step).

In the pen pop-up menu, the patterns of the pen tips of the seven types of pens (system registration pens) already prepared by the image processing apparatus, and the marks for selecting the user registration pen and the cutting pen are displayed. When the operator moves the mouse 19 and selects one of the system registration pens (step; Y), the pen is selected to draw a figure. On the other hand, if the operator selects the user registration pen mark (step; Y), a window called a user registration pop-up menu is set (step). Here, the pen tip pattern registered by the user is displayed. When the operator selects one of these with the mouse 19 (step), this becomes a pen for drawing a figure.

On the other hand, when the operator selects a cut mark from the pen pop-up menu (step; Y), a window called a cut-out pop-up menu is displayed on the display 18 (step). In this window, three marks are displayed, and the operator can specify one of the cut modes of “screen”, “transcription”, and “move” by selecting one of these marks ( Steps).

Here, the “screen” cutout mode refers to a mode for cutting out the same one displayed on the screen. "Post"
The cut mode is a mode for cutting a part of an image stored in an image file (not shown).
The “movement” mode is similar to the “transcription” mode, but refers to a mode in which the cut portion becomes white.

When one of the modes of "screen", "transfer", and "move" is designated (Y), cutting is performed in that mode (step), and the cut image becomes the pen tip.

Editing of the pen tip and setting of the center By the way, the image processing apparatus of the present embodiment can edit the pattern of the pen tip and set the center of the pen tip.
In the case of a user-registered pen, a new pen tip is created and registered by this operation. The pen tip pattern of the user registration pen in the present embodiment is configured by 16 × 16 pixels.

 These operations will be described with reference to FIG.

When the operator selects the pen editor mode for editing the pen (step), a window called a pen editor window is opened on the display 18 in which a pen tip pattern registered by the user or already prepared is stored. Is displayed (step). On the other hand, when the operator selects a mode other than the pen editor mode, the operation of the selected mode is executed (step).

While selecting one of the pens in the pen editor window with the mouse 19, the operator specifies whether the work to be performed is shape display editing or size / center editing. When the shape display editing is designated (step; Y), information (pen information) relating to the designated pen is read from the pen tip pattern storage unit 14 and stored in the RAM 13 (step).

As shown in FIG. 5, a pen shape display edit window 31 is opened at the same time, and the nib of the corresponding pen is displayed in two sizes, an enlarged display 32 and a full size display 33 (step). Here, the enlarged display 32 is for displaying each pixel enlarged in a mesh shape, and the original size display 33 is displayed for each pixel of the display 18 in one-to-one correspondence.

In this state, the operator moves the mouse 19 to the position where the enlarged display 32 is changed, and presses the left or right button. If the left button is pressed (step;
Y), the section of the one square is changed to black (step). On the other hand, when the right button is pressed (step; Y), the section is changed to white (step). Thereafter, the enlargement / actual size display is updated (step).

On the other hand, when the size / center editing is specified (steps; N,; Y), information on the size and center of the pen in the pen information of the specified pen is read from the pen information file and stored in the RAM 13 ( Steps). Thereafter, a pen size editing window is opened on the display 18, and these data are displayed (step). The size of the pen tip can be specified in a predetermined range in the vertical and horizontal directions, thereby making it possible to enlarge or reduce the pen tip. The center position of the pen tip can also be specified using the vertical and horizontal coordinates. The pen tip center position is a center position when the pen is moved or rotated, and needs to be within the size of the pen tip.

If the pen tip size or center is changed (step;
Y), the contents of the corresponding file in the RAM 13 are updated (step), and the changed contents are displayed.

In the above states (steps), the operator
If you specify that you want to keep the current status using 19 (step
; Y), the contents of the pen tip pattern storage unit 14 are updated with the contents of the RAM 13 (step). On the other hand, when the operator specifies resetting (step; Y), the original pen information is restored. That is, the operator restarts the operation from the selection operation of the shape display editing and the size / center editing (steps,
).

If editing is continued without specifying save or reset (step; Y), and in the case of shape display editing (step; Y), the work is restarted from the step, and the size / center edit is performed. If it has been (N), the work will be restarted from the step.

Editing Using a Pen When a pen is selected and its size and center position are set, various figures can be created by moving the mouse 19 or specifying a numerical value such as the radius of a circle. These will be described below.

FIG. 6 shows an outline of editing an image using a pen.

When editing an image with the pen, the user positions the cursor on a window called a herald window displayed on the display 18 and presses the button of the mouse 19 (step). When the operation of the mouse 19 is performed without placing the cursor on this window, a work corresponding to the operation is executed (step).

When the herald window is selected, a menu window called a pop-up menu is displayed on the display 18 (step). In this window, items called "palettes" are displayed. Since the operation to be performed is a stage before the operation of drawing using a pen, an item called “palette” must be selected. When an item other than “palette” is selected by the mouse 19 (step; N),
Other work will be performed (step).

If “Palette” is selected, display 18
A palette window is displayed at the top of (step).

FIG. 7 shows this palette window. Five attribute boxes 42 in the palette window 41
46 are arranged in a horizontal row, and a first display area 47 and a second display area 48 are arranged therebelow. In the first display area 47, the height and width of the selected pen are displayed, and in the second display area 48, various data for drawing the changed size and graphic of the pen are displayed. It is displayed.

The operator can draw various figures by setting the pen to a desired state while the palette window 41 is displayed, as described later. The figure is drawn in a window called an image canvas opened below the palette window 41. Palette window 41
Is closed, the close mark displayed as "Close" at the top of this window 41 is selected with the mouse 19 (step).

Next, a description will be given of the operation of specifying attributes for creating an image with reference to FIG.

When the mouse 19 designates one of the attribute boxes 42 to 46 in the palette window 41 in the state where the palette window described in FIG. 6 is displayed (FIG. 8 (step)) (step; Y), An image is created using the attributes (step), where the attributes are classified into five expression forms of the image, and the respective attribute boxes 42 to 46 correspond to these. If a location other than the attribute boxes 42 to 46 is designated, other operations will be performed (step).

Next, the operation when the pen is designated as the attribute, that is, when the attribute box 42 is designated in FIG. 9, will be described. Thereafter, the steps shown in FIG. 8 and the specific contents of the steps will be described.

In FIG. 9, when the operator designates the pen attribute box 42 (step), a pop-up menu is displayed on the display 18 (step). Mouse 19
Select the pen type from this (step),
The height and width of the pen are displayed in the first display area 47 (step).

As already described in the section of “pen type”, the pen includes a system registration pen, a user registration pen, and a cutting pen. When one of the system registration pens is selected, the CPU 11 reads out a correspondence table indicating the height and width of the pen and its “black” pattern portion from the pen tip pattern storage unit 14 and reads the contents (pixel unit and pixel unit). (In mm at the time of printing) is written in the RAM 13 and displayed. The display content of the first display area 47 in FIG. 7 shows one example.

On the other hand, if one of the user registration pens is selected, assuming that it is composed of 16 × 16 pixels as shown in FIG. Regardless of the display, the display is 16 pixels in both height and width, and the values converted to mm are displayed. Also, when the operator selects the cutting pen, the height and width of the cut portion measured during the image cutting operation are displayed in pixel units and mm units, respectively.

In this state, when the operator again designates the pen attribute box 42 and presses the mouse 19 (step), another pop-up menu is displayed (step). When the item "convert" is selected from this pop-up menu (step), an operation for changing the size, angle, etc. of the pen tip is performed (step). These will be described later. When an item other than “conversion” is selected (step; N), another operation is performed (step).

On the other hand, if an attribute box 43 to 46 or a mark other than the pen attribute box 42 is specified in the step (step), another operation is performed (step). If neither is specified, an image is created in the image canvas (step).

Next, the operation of arbitrarily rotating the pen will be described with reference to FIG. For the effect of pen rotation, see FIG. 32 and FIG.
This is as described in FIG.

In the state where the pop-up menu is displayed in the step of FIG. 9 (step of FIG. 10), when the item “rotation” in this menu is selected (step;
Y), the display of the pop-up menu is turned off (step), and a frame of the size of the pen tip is displayed at the position where the cursor was displayed (step). This nib is
The data selected in the pen nib selection operation is read from the pen nib data storage unit 15.

When an item other than “rotation” is selected, the operation related to the specified item is performed (step).

Now, when a frame of the size of the pen tip is displayed at the position of the cursor, the mode in which the pen tip is to be rotated will be set. In this state, the operator can freely move the mouse 19 to move the frame of the pen tip. . When the button of the mouse 19 is pressed at an arbitrary position (step), the coordinates of the point corresponding to the upper left corner shown in FIG.
Registered in 3 (step). From this point, a rotation display mark 54 as shown in FIG. 12 is displayed in the second display area 48 in the palette window 41 (step). Further, the CPU 11 monitors the movement of the mouse 19 from this point of time and obtains the rotation angle. The rotation angle is represented by the angle θ of the long side including the pin point 51 as shown in FIG. The calculation result is displayed in the second display area 48 as shown in FIG. At the same time, the frame having the size of the pen tip is displayed at an angle θ described above (step). The above display operation is performed sequentially until the button of the mouse 19 is released (step).

When the button of the mouse 19 is released (Step; Y), the pattern of the pen tip at that time is registered in the pen tip data storage unit 15 (Step), and all operations for rotating the pen tip are completed.

FIG. 13 shows a pen tip enlarging operation. This operation is different from the pen tip expansion operation described below, and refers to the enlargement of the pattern by a similar shape.

In the state where the pop-up menu is displayed in the step of FIG. 9 (step of FIG. 13), when the item “enlarge” in this menu is selected (step;
Y), the display of the pop-up menu is turned off (step), and a frame of the size of the pen tip is displayed at the position where the cursor was displayed (step). This nib is
The data selected in the pen nib selection operation is read from the pen nib data storage unit 15.

When an item other than “enlargement” is selected, work is performed on the specified item (step).

Now, when a frame of the size of the pen tip is displayed at the position of the cursor, a mode for enlarging the pen tip is set. Even in this state, the operator can freely move the mouse 19 to move the pen tip. When the button of the mouse 19 is pressed at an arbitrary position (step), the coordinates of the point corresponding to the upper left corner shown in FIG.
(Step). From this point, an enlarged display mark 56 as shown in FIG. 15 is displayed in the second display area 48 in the palette window 41 (step). Also
From this point, the CPU 11 monitors the movement of the mouse 19, and thereby obtains the height and width of the pen tip.

FIG. 16 illustrates this principle. Assuming that the coordinates of the pinpoint registered in the step are P1 and the current coordinates are P2, a quadrangle 58 formed by a diagonal line 57 connecting these coordinates
The length L1 of the short side is the amount of enlargement of the pen tip. Therefore, the height of the pen tip is a value obtained by modifying this length L1 with the original height of the pen tip itself, and the width of the pen tip is obtained by modifying the length L1 with the original width of the pen tip itself. Value.

As shown in FIG. 15, the calculation result is displayed in the second display area 48 in units of pixels and units of mm (step). The above display of the height and width is successively performed until the button of the mouse 19 is released (step).

When the button of the mouse 19 is released (Step; Y), the pattern of the pen tip at that time is registered in the pen tip data storage unit 15 (Step), and all operations for enlarging the pen tip are completed.

Next, the pen tip extension operation will be described with reference to FIG. In the case of pen tip extension, the ratio of height to width can be set freely.

In the state where the pop-up menu is displayed in the step of FIG. 9 (step of FIG. 17), when the item “extended” in this menu is selected (step;
Y), the display of the pop-up menu is turned off (step), and the pen tip is displayed at the position where the cursor was displayed (step). The pen tip is selected in the pen nib selecting operation, and data relating to this is read from the pen tip data storage unit 15.

When an item other than “extended” is selected, work is performed on the specified item (step).

When a frame of the size of the pen tip is displayed at the position of the cursor, the mode for extending the pen tip is set. Even in this state, the operator can freely move the mouse 19 to move the pen tip. When the button of the mouse 19 is pressed at an arbitrary position (step), the coordinates of the point corresponding to the upper left corner shown in FIG.
(Step). From this point, an extended display mark (same as the enlarged display mark) 56 as shown in FIG. 15 is displayed in the second display area 48 in the palette window 41 (step). Also, CPU 11 starts mouse 1
Monitor the movement of 9 and thereby determine the height and width of the nib.

FIG. 18 illustrates this principle. Assuming that the coordinates of the pinpoint registered in the step are P1 and the current coordinates are P2, a quadrangle 58 formed by a diagonal line 57 connecting these coordinates
The length L2 of the side in the height direction becomes the height expansion amount, and the length L2 in the width direction becomes the width expansion amount. Therefore, the pen tip height is a value obtained by correcting the length L2 by the original height of the pen tip itself, and the pen tip width is a value obtained by modifying the length L3 by the original width of the pen tip itself. It is.

As shown in FIG. 15, the calculation result is displayed in the second display area 48 in units of pixels and units of mm (step). The above display of the height and width is successively performed until the button of the mouse 19 is released (step).

When the mouse 19 button is released (A step;
Y), the pattern of the pen tip at that time is registered in the pen tip data storage unit 15 (step), and all operations for extending the pen tip are completed.

Next, in Fig. 19, 4

When the drawing attribute box 46 is selected by the mouse 19 in the step of FIG. 8 (step of FIG. 19), a pop-up menu for specifying the drawing method is displayed (step). The operator selects a square mark from these (step; Y). If a mark of another figure is selected (N), the operation of drawing the selected figure is executed (step).

If a square mark is selected from the pop-up menu, the display of the pop-up menu is turned off at this point (step). In this state, when the operator operates the mouse 19 to move the cursor to the image canvas (step), the pen point in the currently specified state is displayed instead of the cursor (step). In this state, the operator can move the mouse 19 to freely move the pen tip in the image canvas.

When the button of the mouse 19 is pressed at an arbitrary position (step), a quadrangular mark (same as the enlarged display mark) 56 as shown in FIG. 15 is displayed in the second display area 48 (step). Then, the coordinates of the pressed point are determined and registered in the RAM 13 (step). After this, as long as the button is kept pressed, the length L of the two sides of the rectangle corresponding to the diagonal, as shown in FIG.

And the display of height and width data is turned off (step). Then, the same image as the obtained quadrangle is drawn on the pen tip is written into the display RAM in the display control device 17, and is displayed on the display 18 (step).

Next, the operation of drawing a box on the image canvas will be described with reference to FIG. Here, the box refers to a state where the inside of the square is painted in a predetermined pattern. In the case of the aforementioned quadrilateral, there is no such pattern inside.

When the drawing attribute box 46 is selected by the mouse 19 in the step of FIG. 8 (step in FIG. 20), a pop-up menu for specifying the drawing method is displayed (step). The operator selects a box mark from these (step; Y). If a mark of another figure is selected (N), the operation of drawing the selected figure is executed (step).

When the box mark is selected from the pop-up menu, the display of the pop-up menu is turned off at this point (step). In this state, when the operator operates the mouse 19 to move the cursor to the image canvas (step), the cursor is displayed as a cross-shaped instruction mark instead of the cursor (step). In this state, the operator can move the mouse 19 to freely move the pen tip in the image canvas.

When the button of the mouse 19 is pressed at an arbitrary position (step), a box creation mark (same as the enlarged display mark) 56 as shown in FIG. 15 is displayed in the second display area 48 (step). Then, the coordinates of the pressed point are determined and registered in the RAM 13 (step). After that, as long as the button is kept pressed, the lengths L2 and L3 of the vertical and horizontal (height / width) sides of the rectangle corresponding to the diagonal line are calculated as shown in FIG. A square is displayed (step,). When the button of the mouse 19 is released (step; Y), the display of the mark 56 and the height and width data in the second display area 48 is turned off (step). Then, the obtained box pattern is written into the display RAM in the display control device 17, and the display 18

Incidentally, not only one type of pattern in the box, but also an operator can select a desired pattern.

 FIG. 21 illustrates this selection operation.

When the pattern box 43 shown in FIG. 7 is selected by the operation of the step in FIG. 8 (step), a pop-up menu for selecting a pattern is displayed (step). As the pattern, there are a halftone dot, a grid, and the like. When the operator selects a desired pattern (step), the pattern is registered in the RAM 13 and used for drawing the above-mentioned box.

FIG. 22 shows an operation for drawing a circle on the image canvas.

When the drawing attribute box 46 is selected by the mouse 19 in the step of FIG. 8 (step in FIG. 22), a pop-up menu for specifying the drawing method is displayed (step). The operator selects a circular mark from these (step; Y). If a mark of another figure is selected (N), the operation of drawing the selected figure is executed (step).

If a circular mark is selected from the pop-up menu, the display of the pop-up menu is turned off at this point (step). In this state, when the operator operates the mouse 19 to move the cursor to the image canvas (step), the pen point in the currently specified state is displayed instead of the cursor (step). In this state, the operator can move the mouse 19 to freely move the pen tip in the image canvas.

When the button of the mouse 19 is pressed at an arbitrary position (step), a circular creation mark 61 as shown in FIG. 23 is displayed in the second display area 48 (step). Then, the coordinates of the pressed point are determined and registered in the RAM 13 (step). After this, as long as the button is held down,
As shown in the figure, a straight line 62 connecting the pinpoint coordinate P1 and the current coordinate P2 is calculated as the radius of the circle, and is displayed in the second display area 48 (step). When the button of the mouse 19 is released (step; Y), the display of the data relating to the mark 61 and the radius of the circle in the second display area 48 is turned off (step). Then, the same image as the obtained circle drawn with the pen tip is written into the display RAM in the display control device 17, and this is displayed on the display 18 (step).

Finally, the operation of drawing an ellipse with the pen tip on the image canvas will be described with reference to FIG.

When the drawing attribute box 46 is selected by the mouse 19 in the step of FIG. 8 (step in FIG. 25), a pop-up menu for specifying the drawing method is displayed (step). The operator selects an elliptical mark from these (step; Y). If a mark of another figure is selected (N), the operation of drawing the selected figure is executed (step).

If an oval mark is selected from the pop-up menu, the display of the pop-up menu is turned off at this point (step). In this state, when the operator operates the mouse 19 to move the cursor to the image canvas (step), a frame having the size of the currently designated pen tip is displayed instead of the cursor (step). In this state, the operator can move the mouse 19 to freely move the pen tip in the image canvas.

When the button of the mouse 19 is pressed at an arbitrary position (step), the oval creation mark 63 as shown in FIG.
Is displayed in the display area 48 (step). Then, the coordinates of the pressed point are determined and registered in the RAM 13 (step). After this, as long as the button is held down,
As shown in Fig. 18, 4 corresponding to the diagonal line inscribed in the ellipse
The lengths L2 and L3 of the vertical, horizontal and two sides of the square are calculated and displayed as height and width (step,). When the button of the mouse 19 is released (step; Y), the display of the mark 56 and the height and width data in the second display area 48 is turned off (step). Then, the same image as the obtained ellipse is drawn with the pen tip is written in the display RAM in the display control device 17, and is displayed on the display 18 (step).

Other graphics can be created by the same operation, and the pen tip can be freely changed, so that a complicated image can be created by a relatively simple operation.

Although various operations are performed using the mouse in the embodiment, the same operation can be performed using another pointing device such as a cursor key.

[Effects of the Invention] As described above, according to the present invention, a cutout means for cutting out a designated area of desired image data is prepared, so that various bit patterns of a pen tip desired by a user can be easily created. be able to. Further, since the editing means is provided with changing means for changing the position of the bit pattern of the pen tip cut by the cutting means as the center of the pen tip, for example, when the rectangular nib is moved, the bit of the pen tip is moved. By setting the position of the pen tip center at the corner of the pattern, the bit pattern of the pen tip can be accurately moved to the corner of another larger rectangular figure by operating a pointing device such as a mouse. By setting the position as the center of the pen tip at the bottom of the bit pattern of the pen tip, the pointing device can also be operated to move accurately on a straight line that matches the bottom of the bit pattern of the pen tip. it can. Also, by changing the position of the bit pattern of the pen tip as the pen tip center, it is possible to delicately change the expression of the line by the pen when the pen tip is rotated.

Further, since the bit pattern data defining the pen tip such as the bit pattern of the pen tip cut by the cutting means can be edited (including changes) in this manner, a pattern corresponding to various usage modes can be obtained. Modifications and changes can be made to obtain the appropriate pattern. In addition, the bit pattern data as an editing result of the editing means is registered in the storage means together with size information including a numerical value of a predetermined unit relating to the bit pattern data, so that the bit pattern data can be selected as the bit pattern of the pen tip. Compared to the case where only the pen tip pattern prepared by the device or system is selected, the range of selection is expanded,
A more suitable pattern can be selected. Further, according to the present invention, at the time of selecting a bit pattern or registering in the storage means, at least one of the data and the size information relating to the corresponding bit pattern data are displayed, so that it is easy to set that the pen is in a desired use state. In addition to this, it is possible to easily confirm whether or not the pen is appropriate when the pen is actually used or registered by this display. Therefore, there is an advantage that operations such as image editing are quick and easy.
