Description: TECHNICAL FIELD The present invention relates to a graphics coordinate control device, and particularly
CRT (cathode ray tube) using an information processing device such as a computer
And image printers, and display devices such as XY plotters.
Manages the drawing position when drawing images (characters, figures)
The present invention relates to a graphics coordinate control device for controlling. 2. Description of the Related Art Conventionally, this type of coordinate control device requires a computer to perform a procedure.
By incorporating (programming), character position recognition is
It is managed and controlled by the strike coordinate system, and the dot position recognition is
Management control is performed in the central coordinate system, and both management control mechanisms
Is configured independently. Here, a CRT device equipped with high-resolution graphics
The relationship between the dots (pixels) and the text (character) area
It is as shown in FIG. Each text displayed on the CRT
As a strike, 2-byte text as shown in Fig. (B)
Then, the 2-byte text is vertically
1-byte text that is divided into two by the dividing line in the direction
Yes, generally text with a set of dots
Is represented (see FIG. (D)). The text display area is 16 dots vertically for 2-byte text.
Occupies 16 dots in the horizontal direction (16x16)
You. Text position when displayed on this text screen
Is within the range of 25 lines vertically and 40 columns horizontally (25 lines x 40 columns) (A)
It is expressed numerically as in the example. In the case of 1-byte text, 16x8 dots worth of text
As the display area, the text position within the range of 25 lines x 80 columns
Is expressed. 1-byte text and 2-byte text
When mixed with a list of text, it is usually 25 lines x 80 columns of text
It is generally expressed by position. On the other hand, the dot position on the CRT screen is as shown in the example in Fig. (A).
It is expressed numerically within the range of 400 × 640. In the description below
Represents these positions by (vertical numerical value, horizontal numerical value)
I decided to. In this example, the 2-byte text is 16x16 dots.
In the case of occupying the
Of course, you can also occupy many dots.
is there. By the way, recent text input devices such as Japanese word processors
At, the position of the character data on the CRT screen is recognized as a character position.
The cursor can be moved and positioned, and then executed.
However, even in graph creation input, the pixel is special
You can use the position recognition cursor to recognize the position or directly
It is also practiced to indicate the setting numerically. However, for pixel position recognition, for example (0,
Equivalent to move the cursor from point 0) to point (0,539)
Takes a lot of time, and the pixel position is directly indicated by a numerical value.
That is a hassle. It uses text memory and graphics memory
Independently configured, text coordinate system and graphics as described above
It is caused by the independent control of the x coordinate system.

The value held by the means 62 is displayed. Next, as shown in (C2),
When the "cat" character is input from the means 12 ', the data display
The "cat" character is displayed on the CRT9 due to the step (symbol omitted).
You. Next, when the "expansion" Key is input from the means 13 ', the expansion
The control means operates and refers to the held value of the means 62 and displays it on the CRT9.
The enlargement target character "cat" is displayed (indicated by (D1) in the figure.
Next, move the B cursor as shown in (d2), and press (e).
As shown, input the P-function character designation by means 13 'and means 12'.
When you press it, the Cats coordinate control 57 will work, and position it with the B cursor.

Corrected characters (images) are displayed as cursor information (CKM, BKM or VD
This is an instruction key to be registered as a (retention memory). As described above, the present invention provides a series of Cats coordinate control.
By using it as a graphics coordinate position recognition means
In addition to the conventional dot coordinate management (or control),
Not only the position (C coordinate, B coordinate) but also the character coordinate
The position can be recognized independently by the enlarged P coordinate position.
Therefore, it is possible to recognize a large number of fine dot positions quantitatively.
Area recognition without specifying C coordinates, B coordinates, and P coordinates
Alternatively, the position can be recognized. Furthermore, within each area
Dot coordinates (for P coordinates, virtual dot (VD) coordinates)
Since it can be easily controlled, you can use the D cursor
The effect is to draw a solid line figure. In addition, the coordinates of each coordinate (excluding D coordinate) are moved in dot units.
Mark management is also possible, and the position is recognized by C and B coordinates.
It is easy to generate P coordinate values and display the area.
You. Furthermore, conventionally, all procedural statements specify dot coordinate values.
However, if you adopt the Cats coordinate control method, for example, PS
The position (X, Y) pointed to by the ET (X, Y) sentence is changed according to each mode.
The position on the D coordinate / C coordinate / B coordinate / P coordinate / VD coordinate.
And display it in dots, C area / B area / P area
/ VD area can be expected to be filled.
Also, image transfer between different coordinates (eg 8 coordinate position image)
To the P coordinate position, etc.) and specify the coordinate position

Claims (1)

(57) [Claims] As a drawing entry on the display screen, dot position coordinate management control means for moving and recognizing the pixel of the display device as a unit, and character position coordinate management control means for moving and recognizing the character area consisting of a plurality of pixels as a unit. A graphics coordinate control device having a first coordinate indicating a position of the first region in a coordinate system in which a first region obtained by enlarging the character region vertically and horizontally to a desired magnification is used as a unit (hereinafter referred to as a P coordinate system). A first start point in the dot coordinate system obtained by the position 1 and a first end point in the dot coordinate system obtained based on the first start point and one unit of the first area. Then, a P-coordinate control unit that controls movement and position recognition on the display screen in units of an area (hereinafter, referred to as a P area) formed of the first start point and the first end point, and the pixels in the vertical and horizontal directions. Designated by a second position indicating the position of the second area from the first start point of the P area in a coordinate system (hereinafter, virtual dot coordinate system) in which the second area enlarged to a desired magnification is used as a unit. And a second end point in the dot coordinate system obtained based on the second start point and one unit of the second area. A graphics coordinate control device comprising: virtual dot coordinate control means for freely moving and recognizing a position in units of regions (hereinafter referred to as virtual dots). 2. 2. The graphics coordinate control device according to claim 1, further comprising holding means for holding the desired magnification.
