Drawing device and drawing method

TECHNICAL FIELD The present invention relates to a drawing device and a drawing method; the figure includes graphics, characters, letters, symbols, and Arabic numerals.

BACKGROUND OF THE INVENTION There are currently some drawing devices or writing devices, and people have problems when using these softwares, for example, when drawing multiple independent graphics "painting", "drawing", "loading", and "setting" You need to draw the drawing completion after drawing "painting", then start drawing the "picture", and then draw down accordingly. Every time you draw a word, you must click the drawing to complete the action. The action similar to the final drawing is: mouse button double click action , click on a specific button (such as: "Done" button), click on a specific area (such as: click outside the drawing area), and a timer (such as: the user does not perform any drawing action within a certain length of time, then automatically will be current All drawing results generate independent graphics, etc.; therefore, the user continuously emits drawing completion actions during the drawing process, which continuously interrupts the user's operational thinking and continuity of operations.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drawing device and a drawing method that automatically determine the completion of an independent graphic without interrupting the user's operational thinking and continuity of operation.

The above objectives can be achieved by the following two technical solutions:

The first technical solution:

Whether the stroke is currently an independent image.

The condition that each pending stroke is added to the storage module is: if the storage module is empty, the pending stroke is automatically added to the storage module; if the storage module is not empty, the smallest rectangle of the current stroke in the storage module can be accommodated and can accommodate the The minimum rectangle of the pending stroke is determined according to the relative position of the drawing module, and if the spacing is less than the preset value, the pending stroke is added to the storage module.

The condition for determining that the current stroke is an independent image is: The command to receive the end command output module or the pending stroke cannot be added to the storage module.

Whether the stroke is currently an independent image.

A method for drawing by the above drawing device, comprising the following steps: Step 1): drawing a pending stroke in the drawing module, which may be a point or a line;

Step 2): determining whether the pending stroke meets the condition of being added to the first storage module, if yes, then going to step 4), if not, then going to step 3);

Step 3): Identify each of the current strokes of all the storage modules as independent images and save them for processing. Clear all the storage modules, add the pending strokes to the first storage module to form the current strokes, and go to step 6. );

Step 4): adding the pending stroke to the first storage module, if the first storage module is empty, the pending stroke becomes the current stroke in the first storage module; if the first storage module If not, the current stroke in the pending stroke and the first storage module is followed by the drawing mode. The relative positions of the blocks are combined to form a new current stroke of the first storage module;

The condition that the current stroke in the previous storage module in step 5) is added to the next storage module is: if the next storage module is empty, the current stroke in the previous storage module is automatically added to the storage module; If the next storage module is not empty, the smallest rectangle that can accommodate the current stroke in the next storage module and the smallest rectangle that can accommodate the current stroke in the previous storage module are judged according to the relative position of the drawing module. If the pitch is less than a preset value, the pen to be determined is Add a painting to the next storage module.

As can be seen from the above two technical solutions, the present invention determines whether an independent graphic is completed by setting a preset condition, and does not require the user to perform a completed operation, thereby avoiding interrupting the user's operational thinking and continuity of operation.

The above two devices and methods belong to a general concept. For the first solution, since only one storage module for storing the current strokes forming the independent image is provided, if the operator draws according to the preset conditions, an independent image is drawn. The device can be caused to generate a separate image by drawing the next stroke or by actively stopping the drawing command. Therefore, in the process of drawing multiple independent images, when the next independent image is not identified, it is determined that the previous independent image is generated. .

For the second solution, the present invention sets a plurality of storage modules for storing the current strokes forming the independent images. When the operator draws according to the preset conditions, if the mapping is not actively stopped, the number of the storage modules needs to be the same. After multiple independent images, the next drawing is drawn or the drawing command is actively stopped to cause the device to generate multiple independent images. Therefore, in the process of drawing multiple independent images than the number of storage modules, the active image is not actively stopped. If you draw, you have to wait until you have drawn multiple independent images with the same number of memory modules before you can create a separate image.

The invention also specifically provides a drawing device and a drawing method for setting two storage modules:

A drawing device, comprising: a drawing module having positional parameters for receiving drawing to generate each pending stroke correspondingly according to each stroke, the pending stroke is a point or a line; two storage modules for Storing a current stroke composed of a pending stroke; an end command output module for accepting a human operation to issue a command to stop drawing; a control module, which is respectively connected to the drawing module, the two storage modules, and the end command output module, It is used to determine whether each pending stroke can be added to the first storage module to form the current stroke, whether the current stroke in the first storage module can be added to the second storage module to form the current stroke and identify the first storage module and The current stroke in the second storage module is determined to be No as a standalone image.

A method for drawing by the above drawing device, comprising the following steps: Step 101): drawing a drawing stroke to be generated in the drawing module, which may be a point or a line;

Step 102): determining whether the pending stroke satisfies the condition that is added to the first storage module, if yes, then proceeds to step 104), if not, proceeds to step 103);

【detailed description】

[Embodiment 1]

As shown in FIG. 1, a drawing device includes a drawing module having positional parameters for receiving a drawing to generate each pending stroke correspondingly according to each stroke, the pending stroke is a point or a line; a storage module of the current stroke composed of strokes; an end command output module for accepting a human operation to issue a command to stop drawing; a control module, which is respectively connected with the drawing module, the storage module, and the end command output module, for determining each Whether the pending strokes meet the requirements of adding the storage module to form the current stroke and whether the current stroke in the storage module is an independent image.

As shown in FIG. 3, the flow of the method for drawing by using the above drawing device includes the following steps: S101: starting the action, the drawing device is initialized, and the drawing module and the storage module are empty;

S102: Drawing a drawing to generate a pending stroke, which may be a point or a line;

S103: determining whether the pending stroke meets the conditions that are entered into the storage module, if yes, then proceeds to step S104, if not, then proceeds to step S105;

S104: adding the to-be-determined stroke to the storage module, if the previous storage module is empty, the pending stroke becomes a 3⁄4 front stroke; if the storage module is not empty, the current stroke in the pending stroke and the storage module is followed. Combining the relative positions of the drawing modules to form a new current stroke of the storage module; Go to step S106;

S105: Identify the current stroke in the storage module as a separate image and save it for processing, clear the storage module, and add the pending stroke to the storage module to become the current stroke;

S106: Whether a command to stop drawing is received, if yes, go to step S107; if not, then turn Go to step S102;

S107: Identify the current stroke in the storage module as a separate image and save it for processing, and clear the storage module and the drawing module;

S108: End.

The determining condition of step S103 is: if the storage module is empty, the pending stroke is automatically added to the storage module; if the storage module is not empty, the minimum rectangle of the current stroke in the storage module can be accommodated. The minimum rectangle capable of accommodating the to-be-determined stroke is determined according to the relative position of the drawing module, and if the spacing is less than the preset value, the pending stroke is added to the storage module.

For example, the upper left corner of the drawing module is the origin, the horizontal direction is the X-axis positive direction, and the vertical direction is the y-axis positive direction. The following describes how to define the minimum rectangle and how to determine the distance between the two rectangles.

The minimum rectangle of the pending stroke is: The pending stroke is composed of many points with coordinate parameters (X, y), and the smallest X value and the smallest y value of the coordinate parameters of these points constitute the coordinates of the upper left corner of the smallest rectangle (Xmin_d) , Ymin.d ), the smallest x value and the largest y value of the coordinate parameters of these points constitute the coordinates of the lower left corner of the smallest rectangle (Xmin-d, Ymax-d ), and the largest x value of the coordinate parameters of these points The minimum y value constitutes the coordinates (Xmax-d, Ymin_d) of the upper right corner of the smallest rectangle. The largest X value and the largest y value of the coordinate parameters of these points constitute the coordinates of the upper right corner of the smallest rectangle (Xmax-d, Ymax_d) The four corners that define the smallest rectangle of the pending stroke naturally define the smallest rectangle of the stroke to be determined.

At present, the minimum rectangle of a stroke is: The current stroke is composed of many points with coordinate parameters (X, y), and the smallest X value and the smallest y value of the coordinate parameters of these points constitute the coordinates of the upper left corner of the smallest rectangle (Xmin_m , Ymin_m ), the smallest x value and the largest y value of the coordinate parameters of these points constitute the coordinates of the lower left corner of the smallest rectangle (Xmin_m, Ymax-tn), and the largest x value among the coordinate parameters of these points And the minimum y value constitutes the coordinates (Xmax-m, Ymin_m) of the upper right corner of the smallest rectangle. The largest X value and the largest y value of the coordinate parameters of these points constitute the coordinates of the upper right corner of the smallest rectangle (Xmax_m, Ymax-m ), the four corners that define the smallest rectangle of the current stroke naturally define the smallest rectangle of the current stroke.

It can be seen that the minimum rectangle of the pending stroke and the smallest rectangle of the pending stroke are both axial.

A minimum rectangle A is specifically: upper left corner ( RECTI 01.x, RECTI 01.y ), lower left corner ( RECTI 02.^ RECTI 02.y ), upper right corner ( RECT103.X, RECT103.y ), lower right corner ( RECTI 04.x, RECTI 04.y), the other smallest rectangle B is: upper left corner ( RECT201.X, RECT201.y ), lower left corner ( RECT202.X, RECT202.y ), upper right corner ( RECT203.X, RECT203 .y ), lower right corner ( RECT204.X, RECT204.y ); If the smallest rectangle A is above and the smallest rectangle B is arranged below, the upper and lower spacing of the two smallest rectangles is compared with the preset value, and the spacing between the two is I RECT201 .y- RECT102.y I; If the smallest rectangle A is on the left and the smallest rectangle B is on the right, the left and right spacing of the two smallest rectangles are compared with the preset values, and the spacing between the two is I RECT201.X - RECT103.XI; If there is an overlap point between the smallest rectangle A and the smallest rectangle B, the spacing between the two is considered to be zero; if the minimum rectangle A is included or built in the minimum rectangle B, the spacing between the two is considered to be zero. The arrangement of the smallest rectangle A and the minimum rectangle B, the overlapping point and the arranging relationship can be automatically determined by the software related judgment algorithm. This judgment algorithm is not the invention of the present invention, and is not cumbersome here. Moreover, the preset value may be a fixed value, or may vary depending on the size of the drawing device, the display resolution, etc., or a variable value that is flexibly adjusted by the software according to the thickness of the input stroke. One

As shown in Figure 2, taking the word "chuan" as an example, we will draw and generate three pending strokes on the drawing module during the drawing process.

S201: Turn on the drawing device, initialize, draw the module and the storage module is empty;

S202: Draw on the drawing module to generate a pending stroke "corpse, the control module determines whether the pending stroke" can be added to the storage module, because the storage module is empty at this time, the pending stroke "the corpse is added Storing modules to form current strokes;

S203: At this time, the output module is not pressed according to the end command, and the pending stroke "1" is continuously drawn on the drawing module, and the control module determines whether the pending stroke "!, can be added to the storage module, and the current stroke of the storage module exists", The module determines the spacing between the minimum rectangle C1 of the current stroke "corpse" and the smallest rectangle C2 that can accommodate the pending stroke "1" according to the relative position of the drawing module. Assuming that the spacing HI is smaller than the preset value, the control module will determine the strokes to be determined. "1" is added to the storage module and the pending stroke "" and the current stroke ") in the storage module are combined according to the relative positions of the drawing module to constitute a new current stroke of the storage module "; 1";

S204: At this time, the output module is not pressed according to the end command, and the pending stroke "1" is continuously drawn on the drawing module, and the control module determines whether the pending stroke "1" can be added to the storage module. At this time, the current stroke "1" exists in the storage module, and the control module The minimum rectangle C3 capable of accommodating the current stroke ";1" and the minimum rectangle C4 capable of accommodating the pending stroke "]" are judged according to the relative position of the drawing module. Assuming that the spacing H2 is smaller than the preset value, the control module will be determined. The stroke "I" is added to the storage module, and the pending stroke "I" and the current stroke 'υι" in the storage module are combined according to the relative positions of the drawing modules to constitute a new current stroke of the storage module.

S205: The personnel presses the end command output module, and the control module receives the stop drawing command. At this time, the control module determines that the current stroke of the storage module exists, and identifies the current stroke "Chuan" as an independent image "Chuan", saves the processing and clears the storage module and draws Module

S206: End of drawing; finally, the independent image "Chuan" is obtained.

[Embodiment 2]

As shown in FIG. 4, the difference between the embodiment and the first embodiment is that step S204 to step S205, because of poor drawing, can accommodate the spacing of the smallest rectangle of the current stroke ", and the smallest rectangle that can accommodate the pending stroke "I". According to the relative position of the drawing module, the preset value is greater than the preset value. Therefore, in this embodiment, S204: At this time, the output module is not pressed according to the end command, and the drawing is continued on the drawing module to generate a pending stroke. The control module determines whether the pending stroke "I" can be added to the storage module. At this time, the storage module has the current stroke "". The control module pairs the smallest rectangle C3 that can accommodate the current stroke "", and the smallest rectangle C4 that can accommodate the pending stroke "1", and determines the spacing according to the relative position of the drawing module. The spacing H2, which is greater than the preset value, will be stored. The current stroke "JI" in the module is recognized as a separate image and saved for processing, the storage module is emptied, and the pending stroke "!" is added to the storage module to become the new current stroke "f";

S205: The personnel presses the end command output module, and the control module receives the stop drawing command. At this time, the control module determines that the current stroke exists in the storage module, and identifies the current stroke "1" as an independent image "I", saves the processing, and clears the storage module and draws Module
