DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a character string containing a deformed character.
There are those about the printable character processing apparatus.

[0002]

2. Description of the Related Art Conventionally, as an apparatus of this kind, an apparatus capable of reading and displaying a character corresponding to a character string input from an input unit, for example, a vector font, or outputting it as an image has been proposed.

Further, in a device having a vector font, it is configured such that it is possible to perform scaling (enlargement, reduction) output and deformation output from a vector font basically prepared for one character to various sizes. Further, there has been proposed an apparatus capable of outputting a vector font pattern having a composite shadow effect by filling, whiteout, and various hatching (line shadows, irregular patterns) patterns with respect to a vector font pattern once subjected to coordinate development.

[0004] However, in the above-described modified output of the vector font, it is necessary to set various parameters for outline processing and shadow processing for one character. FIG. 10 is a schematic diagram illustrating a conventional vector font parameter setting screen.

In FIG. 1, reference numeral 31 denotes a vector font pattern which is composed of contour processing information 32, shadow information 33, etc., and the contour processing information 32 is a character type parameter 34a.
To 34c and hatching parameters 35a to 35c,
Furthermore, an outline parameter 36, a fat amount parameter 37, a flat body parameter 38, and an italic body parameter 39
The shadow parameter includes a continuous parameter 40, a discontinuous parameter 41, and the like, and includes a hatching parameter 42a, a shadow amount parameter 42b, and the like.

In order to display the vector font pattern 31, the character type parameters 34a to 34a - 3 are input by the input means.
4c, the hatching parameter 35a is set to white,
The hatching parameter 35c is gray, the outline parameter 36 is black, the flat body parameter 38 is 60%,
It is generated when the italic amount parameter 39 or the like has been specified in the x direction + 15 °.

[0007]

In such a conventional vector font transformation, a desired vector font cannot be transformed unless a necessary various parameter setting operation is performed. It is necessary to specify parameters such as enlargement / reduction ratio, italic direction, italic ratio, fill, white space, hatching parameters, and other parameters such as shadow angle and width while referring to them. There was a problem that even a human was troublesome operation.

In some cases, a design sense is required for the parameter setting itself. In such a case, an unskilled operator can generate a vector font that matches the final image without repeating trial and error. There was a problem that it disappeared.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. In a character processing apparatus capable of outputting a character string including a deformed character, a character processing apparatus for outputting a desired character string among input character strings is provided. Processing device that can visually and intuitively grasp a plurality of types of modified character patterns to be applied, and can output a character subjected to a desired modification from a character string to be output by a simple operation. The purpose is to do.
