As I said: The demos do not use Arial on purpose. Probably it is used as a fallback somewhere. So the question is: why is the demo falling back to Arial ? It means the actually used font (Liberation Sans, line 74 of rptjson) is not found. Michael.

Hello Michael, if the font is not found, why is there not the correct indication of the missing font ? The errormessage is in this case completly wrong. If a fallback should be possible, it should work and not mask the problem and create a false errormessage. Maybe the font liberation Sans is not on a Windows10/64 machine, if this is true i should see the message -> fpreport: Could not find the font <Liberation Sans> in the font cache. Or -> EReportFontNotFound: >> Font not found: "Liberation Sans". Andreas Am 27.12.2019 um 16:00 schrieb Michael Van Canneyt: > > As I said: > > The demos do not use Arial on purpose.

Hello, Can we please tackle one problem at a time ? The first problem is: Why is the "liberation sans" not found ? Once we've established that, we can check why the fallback is not found, and perhaps the error message. Michael.

Hello, i think there is a problem with definiton of HumanFriendlyName and PostScriptName. it looks like the Arial font is the default (parent font) under windows. But the name Arial is not correct, it should be translated to the correct PostScriptFontName = ArialMT. Because a search in Font(Fontname) is as search with the postscriptname and not with the human readable Font name. Actual i have fixed this for me with fnt := gTTFontCache.FindFont(AFontName); // we are doing a PostScript Name lookup (it contains Bold, Italic info) in function TFPReportExportPDF.FindFontIndex(const ADoc: TPDFDocument; const AFontName: string): integer; but i think, this is not the soloution. It should be done in the prepaering of the report.
