Abstract

PURPOSE:To improve efficiency in the edit of a document in the case of generating the document in a limited space by editing a character string and a graphic which encloses the character string simultaneously, and performing re-arrangement in the graphic by selecting a character size automatically corresponding to the deformation of the graphic. CONSTITUTION:A graphic plotting parameter is updated corresponding to deformation instruction to the graphic enclosing the character string, and either processing as follows is performed according to the instruction of a user. In other words, the new character size of the character string in the graphic is decided by the degree of the deformation of the graphic, and a size nearest to the said size is selected by a font managing table, and a character position in the graphic is calculated, then, the attribute of character arrangement is updated. Or, the graphic is deformed and developed as one image including the inside. In such a way, it is possible to edit character data and graphic data simultaneously at the time of editing the character string and the graphic to enclose the character string, and to improve the efficiency in the edit of the document.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the handling of character data and graphic data in document editing, and provides an effective method particularly when it is desired to simultaneously edit character strings and graphics as one group. Regarding.

[Conventional technology]

An increasing number of high-performance workstations handle multimedia documents that include not only text but also figures, images, and the like.

However, when creating a document, the editing functions for characters such as changing the font size and character spacing, and the editing functions for figures such as enlarging/reducing figures operate separately. If you want to enlarge or reduce the size, you need to switch each editing function and specify them separately.

Also, for this purpose, there is a string and a shape surrounding it,
When a figure is transformed, when trying to insert a character string into the transformed figure again, the user calls up the formatting screen or character property sheet, and changes the character size. , you must reset the character spacing, etc., and repeat through trial and error until the characters are included in the figure.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, when creating a document, the editing function for characters and the editing function for graphics are independent.1 For example, if you want to modify a highlighted part of a character string by enclosing it in a rectangle, It was necessary to switch the editing functions of Furthermore, when attempting to insert a character string within the corrected rectangle, it was a time-consuming task, as it involved fine-tuning the character spacing and cutting and pasting only the character string.

An object of the present invention is to improve the efficiency of document editing by making it possible to edit character data and graphic data simultaneously when editing a character string and the graphics surrounding it.

[Means for solving problems]

In order to achieve the above object, the present invention first gives an instruction to group a designated character string and the graphics surrounding it, and then transforms the graphics. When handling a character string as character data, a new character size is selected depending on the degree of graphic transformation, and the character position of the new character size is calculated and placed within the transformed graphic. When a character string is treated as image data, the image is transformed according to the enlargement/reduction ratio of the figure.

[Effect]

Types of figures such as circles and rectangles and figure drawing parameters such as coordinates are stored as figure data.

Additionally, attributes of character arrangement such as character size and character spacing and character codes are stored as text data. Furthermore, a font management table for managing the types and sizes of fonts possessed by the document editing device is prepared.

Update the figure drawing parameters according to the transformation instructions for the figure surrounding the character string, and perform the following (1) according to the user's instructions.
, (2) is performed. (1) Determine the new character size of the character string in the shape based on the degree of shape deformation, select the closest size to the character size from the font management table, calculate the character position in the shape, and update the character placement attributes. do. (2) Depending on the degree of shape transformation, the shape is transformed and developed as one image, including its interior.

〔Example〕

Hereinafter, one embodiment of the present invention will be described using the drawings. FIG. 2 shows an example of a screen display when the figure surrounding the character string is a rectangle and the degree of figure deformation is determined by the area ratio before and after the deformation.

A character string of character size 204 and a rectangle 200 surrounding it are displayed on the screen. If the rectangle 200 is transformed into a rectangle 201 after an instruction to treat the example character and the rectangle as one group, the area ratio of the figure before and after transformation remains the same, so the character position is changed with the same character size 204 as shown in the figure.

When the rectangle 200 is transformed into 202, a character size 205 is selected according to the area ratio, and a new character position is determined and changed in the rectangle 202 using the character size 205.

When treating a character string within a rectangle as an image, use the rectangle 20
The dot pattern of the character is transformed according to the degree of transformation from 0 to 203, and the display is changed as shown in the figure.
