Abstract
A character within a font is enlarged to a desired size by first determining whether the font contains existing or predefined variants of the character having the desired size. If no appropriately sized variant exists, the enlarged character is assembled from a plurality of component glyphs that are stored with the font, wherein the component glyphs include an extender that may be duplicated within the assembled character in order to achieve the desired size. In one embodiment, the font includes tables containing records of the enlarged variants for a particular character, as well as part records for the component glyphs used to assemble the enlarged character.

21. A computer storage medium having computer-executable instructions for performing a method of enlarging a character within a document, wherein the character is a component of a predetermined font, the method comprising:
-
determining a desired size for the character;
assembling the character from a plurality of component glyphs stored within the predetermined font, wherein each component glyph includes at least one straight line connector that overlaps a connector of an adjacent component glyph;
calculating a potential increase in character size resulting from reducing connector overlap between adjacent component glyphs to a predetermined minimum amount of overlap, wherein the predetermined minimum amount is greater than zero; and
determining if the potential increase in character size is equal to or greater than the desired character size. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A computer storage medium having computer-executable instructions for performing a method of enlarging a character within a document, wherein the character is a component of a predetermined font, the method comprising:
-
determining a desired size for the character;
assembling the character from a plurality of component glyphs stored within the predetermined font, wherein each component glyph includes at least one straight line connector for overlapping a connector of an adjacent component glyph;
adding an extender glyph to the character to increase the overall size of the character, wherein the extender glyph comprises a straight line segment having a connector at each end;
following the addition of the extender glyph, determining if the overall character size is equal to or greater than the desired character size; and
upon determining that the overall character size is not equal to or greater than the desired character size, repeating the step of adding an extender glyph to the character until the overall size of the character is equal to or greater than the desired character size. - View Dependent Claims (31, 32, 33, 34, 35, 36)

37. A computer storage medium having computer-executable instructions for generating an enlarged version of a specified character within a predetermined font, wherein the specified character is enlarged in at least one of a vertical or horizontal direction, and wherein the computer-executable instructions define a plurality of tables included with the predetermined font, the plurality of tables comprising:
-
a first table including a first count of font characters that are capable of growing in a vertical direction and a second count of font characters that are capable of growing in a horizontal direction; and
a second table including a count of component glyphs that are used to assemble an enlarged version of the specified character, the second table further including an array of component glyph records describing each component glyph used to assemble the enlarged version of the specified character, the array comprising a first value representing a glyph identifier for each component glyph, and a second value indicating whether the component glyph is an extender that can be repeated during assembly of the specified character, wherein the extender adds length or width in order to achieve a desired size of the specified character; and
wherein the first and second tables enable a typesetting application utilizing the predetermined font to assemble an enlarged version of the specified character from component glyphs. - View Dependent Claims (38, 39)
