DebenuPDFLibraryPNG.pas has a function TPNGReader.FilterData where there's a code snip like this: ... SetLength(FAlphaData, AlphaDataByteCount * FHeight); if Length(FImageData) > 0 then begin FillChar(FAlphaData[1], Length(FAlphaData), 0); end; ... This code is buggy and should most likely be: ... SetLength(FAlphaData, AlphaDataByteCount * FHeight); if Length(FAlphaData) > 0 then // FAlphaData replaced here!!! begin FillChar(FAlphaData[1], Length(FAlphaData), 0); end; ... This caused some confusion within our development team.  If this is not fixed in version 11, you could probably merge in the fix there. |

Hi Walther, Yes, you are correct, that appears to be a mistake. We'll fix that in the next release. Thanks! Just be careful posting source code on forums, this is only a small snippet so not a big deal but preferably just post the version number, filename and line number with suggested change. If there's a bigger suggested change better to email Debenu directly. Cheers, - Rowan.
