How to load a custom font from a stream instead of from a file?
Currently no way to my knowledge,
But fpparsettf.pp has this:
TTFFileInfo = class(TObject)
...
public
// Load a TTF file from file or stream.
Procedure LoadFromFile(const AFileName : String);
Procedure LoadFromStream(AStream: TStream); virtual;
Yes, but the font cache/manager in fpttf does not support this, and
all font access happens
through the font cache. (at least that is how I understood Mattias'
request)
Yes. I added two functions and extended the example.
To my surprise it turns out that a ttf file is loaded up to 3 times:
Once for AddFont, once for gTTFontCache and once in SaveDocument.
SaveDocument now uses the TPDFFont stream if available, so only 2 times.
s/SaveDocument/TPDFDictionary.WriteDictionary/
Wouldn't it be better if TPDFDocument.Fonts and gTTFontCache share the
stream?
