Method for calculating CJK emboxes in fonts

A computer program product, stored on a machine-readable medium, comprising instructions operable to cause a programmable processor to:

• set a coordination line for the text line to coordinate a plurality of characters for typesetting the text line,
• determine the dimensions of each of the plurality of characters to be typeset on the text line,
• determine an embox for each of the plurality of characters, the vertical and horizontal size of each embox being said determined character dimensions,
• compare each of the plurality of characters to be typeset on the text line with at least one preselected reference character belonging to the same font, and determine a coordination point for each of the plurality of characters in their said respective embox based on the result of the comparison, and
• coordinate said coordination point for each of the plurality of characters with said coordination line to typeset said plurality of characters on the text line.

A desktop publishing system for controlling typesetting of a text line, comprising:

• a desktop publishing processing control device provided with a font file and with typesetting control means, the font file containing character font information for performing typesetting;
• a display device for displaying data that is being typeset;
• and
• input means for receiving user input;
• said typesetting control means having a text line typesetting control means adapted to arranging a plurality of characters to be coordinated with a coordination line of a text line by
• determining an embox for each of the plurality of characters, each embox having a vertical and horizontal size corresponding to the dimensions of its associated character,
• determining a coordination point by comparing each of the plurality of said characters with at least one preselected reference character belonging to the same font, and
• performing line typesetting processing by coordinating each determined coordination point with said coordination line.
