Display program, data structure and display device

Abstract

A display program for displaying a character by acquiring an instruction for rendering each element composing the character and rendering the each element based on the instruction, the program being executed on a computer, includes a determination function of determining whether the acquired instruction is a complex glyph instruction indicating the use of a complex glyph consisting of a combination of plural parts glyphs as a glyph of the character or other instruction and a rendering function of rendering each of the parts glyphs based on the information concerning the parts glyph acquired following the complex glyph instruction if the acquired instruction is determined as the complex glyph instruction.

Claims

1. A display program for displaying a character by acquiring an instruction for rendering each element composing the character and rendering the each element based on the instruction, the program being executed on a computer, comprising a determination function of determining whether the acquired instruction is a complex glyph instruction indicating the use of a complex glyph consisting of a combination of plural parts glyphs as a glyph of the character or other instruction and a rendering function of rendering each of the parts glyphs based on the information concerning the parts glyph acquired following the complex glyph instruction if the acquired instruction is determined as the complex glyph instruction.

2. The display program according to claim 1, wherein the information concerning the parts glyph contains a glyph index of the parts glyph, and the rendering function comprises a parts glyph acquisition function of acquiring the instruction indicated by the glyph index of the parts glyph and a first parts glyph rendering function of rendering the parts glyph based on the acquired instruction.

3. A data structure for use in a display program for displaying a character by acquiring an instruction for rendering each element composing the character and rendering the each element based on the instruction, wherein a complex glyph instruction indicating the use of a complex glyph consisting of a combination of plural parts glyphs as a glyph of the character is arranged before the information concerning the parts glyph.

4. A display device for displaying a character by acquiring an instruction for rendering each element composing the character and rendering the each element based on the instruction, comprising a determination section of determining whether the acquired instruction is a complex glyph instruction indicating the use of a complex glyph consisting of a combination of plural parts glyphs as a glyph of the character or other instruction and a rendering section of rendering each of the parts glyphs based on the information concerning the parts glyph acquired following the complex glyph instruction if the acquired instruction is determined as the complex glyph instruction.
