[fpc-pascal] Fwd: Re: fcl-report demos not working on windows10/64 with win64 compiled - Font Arial not found

Sat Dec 28 19:47:52 CET 2019

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.

Andreas
