Hi I'm trying to use an embedded font when I LoadFromFile() a PDF and then I AddTrueTypeFont() with the parameter embed = 0, because the font is already in the PDF. But event if I read (Windows CMD --> findstr FontName "FileName") all the included font names and I take the exactly same font name or font family name, my new text does not use this font. Instead the new text is diplayed with a "default" font (Arial in my case, since the font is not installed on my PC. What Do I do wrong?? Here a snippet: Count := QuickPDF.FontCount; Found := FALSE; Index := 1; WHILE (Index <= Count) AND NOT Found DO BEGIN FontID := QuickPDF.GetFontID(Index); IF FontID > 0 then begin QuickPDF.SelectFont(FontID); if QuickPDF.FontName = FontName then Found := TRUE; end; if NOT Found then INC(Index); END; if NOT Found then begin FontID := QuickPDF.AddTrueTypeFont(FontName,0); QuickPDF.SelectFont(FontID); end; |

You cannot add a font you do not have. Thus the AddTrueTypeFont call above will always fail, regardless of the embed flag unless you have the font. If the font is already in the PDF, you should be able to use it unless it has been subsetted, in which case not all characters will be available (and probably not in the standard encoding either) so adding text would be problematic at best. ------------- Eric O |

Thx 4 ur reply. I know that the font is embedded. My task is now to add a text with the already embedded form. When I do FontCount the Result = 2. One is Arial and the other is the other font I need. When I want to add a text to the loaded PDF with this second font, I get a FontId > 0 and use this ID for my text. Yet the new text in the PDF doesn't use that embedded fobt, but a 'default' obe from the PC where the file has been opened. |

You indicate that QuickPDF.FontCount is 2. Did you check that result, or do you just believe that to be true because Acrobat says there are 2 fonts embedded? Unless you call QuickPDF.FindFonts() any fonts that are already embedded in the PDF will not be seen by QuickPDF.FontCount (Check the documentation for FontCount).
Are you positive that the FontName you specify is an exact match for QuickPDF.FontName ? (Is Found being set to TRUE?) Just for a test, try selecting the first font found to see if it will be used: FontID := QuickPDF.GetFontID(1); IF FontID > 0 then QuickPDF.SelectFont(FontID); ... add some text ... ------------- Eric O |
