Subsetting of true type fonts

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

In our existing postscript based product we can create a series of subset fonts based on a single true/opentype font. I can envisage doing something similar in PDF by Adding a truetype font and then creating a set of subset fonts using CreateNewObject and SetObjectFromString. Is there any way then to add the font created into the Font entry in the resources dictionary ?
TIA 
Peter

	Have you looked at the following functions that have been added in QPL 8.11 and 8.12 respectively. http://www.quickpdflibrary.com/help/quickpdf/AddTrueTypeSubsettedFont.php http://www.quickpdflibrary.com/help/quickpdf/AddOpenTypeFontFromFile.php Andrew. Edited by AndrewC - 26 Oct 11 at 7:26AM

	AddOpenTypeFontFromFile doesn't appear in my version of 8.12, but that's a separate matter as it is said to be identical to AddTrueTypeFontFromFile which includes a True Type Font, but defaults to WinAnsiEncoding, presumably I can select a different encoding, but the choice is limited. AddTrueTypeSubsettedFont is close to what I require, but I presume that the string of characters is Unicoded which will not work with some fonts that include glyphs that do not have Unicode values (some east asian and other scripts have multiple forms of a unicode character, only one of the forms can appear in the cmap) So I actually need to be able to select the subset based on glyph ID's Peter
