For example, generation of color information. Reference numeral 5 denotes a ROM (read only memory) 50 for storing a control program for performing processing as shown in FIG. 10, for example, for controlling the entire word processor, and a RAM 51 (random memory) for temporarily storing document data and various data. Access memory), 4 is R
It is a microprocessor (MPU) that actually controls this device according to a control program and various data stored in the OM 50.

Reference numeral 8 denotes a keyboard (KBD) having character input keys and various function keys for inputting character data and various function instructions to the MPU 4. Reference numeral 9 denotes a pointing device (PD) such as a mouse (registered trademark).
The user can designate a position on the screen of the RT display unit 1 and perform input and editing of drawing data. Reference numeral 6 denotes a hard disk device which stores a part of a control program, a document file, character font data, a user-defined dictionary, and the like. Reference numeral 10 denotes a printer for outputting created documents and the like, and reference numeral 11 denotes a floppy disk device for storing and exchanging document files and the like.
These constituent blocks are connected by an I / O bus 7.

With the above configuration, when the document processing apparatus is started, a menu window 21 as shown in FIG. 2 is displayed on the CRT display unit 1, for example. A detailed view of the menu window 21 is shown in FIG. In the menu window 21, icons corresponding to the respective processes are displayed. D. Cursor 22 with 9 etc.
Can be moved to the desired icon position and the switch can be clicked to select the desired process.

At this point, the "document paper" icon 23 in the system menu window 21 is D. Cursor 22 at 9
Is moved and the instruction is given, the display of CRT1 changes, and FIG.
Is newly displayed on the CRT 1.

FIG. 12 shows a detailed view of the command menu window 31 shown in FIG. To color a character or a character string in a document, a “character modification” icon in the command menu 31 in FIG. D. Select with 9.
When selected, the command menu is replaced, and a command menu 41 for character string input as shown in FIG. 4 is obtained. FIG. 13 shows a detailed view of the command menu window.

Here, the "color designation" icon 42 is D.
When the selection is made in step 9, the character or character string is displayed on the CRT 1 with the color (current draw color) set at that time added. Characters or character strings to specify colors are
As with the other modifiers in the figure, selection is made in advance using a range designation command.

When the system is started, the current draw color is set so as to be solid-filled. To change this to a gradation process, the “color setting” icon 43 is selected. When the "color setting" icon 43 is selected, a color palette window 56 is opened as shown in FIG. FIG. 14 is a detailed diagram of the command menu window 55 and the color palette window 56 at this time.
And FIG. Select the "gradation" icon 52 in this window and then the "end" icon 53
Is selected and color setting is completed, the set color information is
Is stored in M51, and when the next color designation command is executed,
Gradation processing is performed. At this time, the gradation process is performed based on a predetermined setting. To set the processing method of the gradation process, select the “gradation” icon 52 and then select the “change” icon 54.

FIG. 6 shows a screen after the "change" icon 54 is selected. As shown in the figure, a gradation setting window 61 is opened. A detailed view of the gradation setting window 61 is shown in FIG. The “start point color” 71 and the “end point color” 72 are displayed on the color palette window 51 by the P.P. D. Use 5 to select. The palette number of the selected color is transferred to the gradation setting window.
At the same time, the actual color is drawn in a small frame beside the column where the palette number is displayed. The “degree of change” 73 sets the rate of change of the color between the start point and the end point, and can be set independently for each of the three items of “hue”, “brightness”, and “darkness”. In the case of the present embodiment, an n-th order equation relating to the distance from the starting point is used for color interpolation between both end points,
n is set here. In the case of FIG. 6, since the hue is 1, the brightness is 2, and the density is １ ／, the hue is interpolated with a straight line, the brightness is interpolated with a quadratic curve, and the density is interpolated with a √ curve. The state of the gradation processing based on the value set here is displayed in the lower frame under simulation.

The "angle of change" indicates the direction of the gradation processing. As shown in FIG. 8, when 0 degree is set, the left end of the character string is the start point and the right end is the end point. When 90 degrees is specified, the upper end is the start point and the lower end is the end point.

The above-described setting is enabled by sequentially selecting the end icon in the gradation setting window and the end icon in the color palette, and is set at both ends of the subsequent character or character string of "color designation". Is embedded with a gradation start command and end command. For this reason, it is not necessary to perform the gradation process again even if a character or a character string is added or corrected.

FIG. 10 is a flowchart showing the flow of gradation processing in the word processor of the embodiment. FIG. 9 shows parameters included in the start / end commands.

First, in step S1, one-line typesetting is performed to determine the position of each character. Characters or character strings sandwiched between the gradation processing commands are assembled in exactly the same manner as otherwise, except that separation is prohibited. When the character position is determined, the pointer is set to the beginning of the line (step S2), it is determined whether or not the code at the pointer position is a command (step S3), and it is determined whether or not the command is a gradation command (step S2). S4) While the pointer is being advanced (step S7), the determination and processing are repeated until the end of the line is reached in step S8, and the document text is sequentially scanned.

If it is determined in step S4 that the command at the pointer position is not a command for instructing the gradation processing, the processing of the command is performed in step S6.

If it is determined in step S3 that the code at the pointer position is not a command, the character position is extracted (step S9), and a one-character output process is performed (step S10).

If it is determined in step S4 that the command at the pointer position is a command indicating gradation processing, each parameter in the command is read, and then the document text is pre-read to search for a gradation processing end command. (Step S11). When the end command is found, the character position of the command is extracted (step S12), and the coefficient of the interpolation function is calculated from the parameters in the previously read start command (step S13). The following equation is used as the interpolation function when x is a position from the start point.

Y = C ₁ x ⁿ + C ₀ where n is the order set as the “degree of change” in the gradation setting window.

Thus, the preparation for executing the gradation processing is completed, the first character is read out in step S14, the character position is extracted in step S15, one-character output processing is performed together with the interpolation function, and the result is output (step S1).
6). When one character has been output, the next character is set (step S18), and steps S15 to S17 are repeated until it is determined in step S17 that the character specified by the gradation processing end command has been displayed.
