I try to load a Portable pixmap to QImage
http://en.wikipedia.org/wiki/Portabl...ap_file_format and QImage not load ..

I hack the XPDF 3.0.2 to enable build on QT4.3 i build on Win Mingw

http://ppk.ciz.ch/qt_c++/XPDF_2_QT.tar.bz2 400kb

the hard work was the pro file to accept minumum to make Portable pixmap


only lib give no problem. main apps say ...

main.cpp: In function `int main(int, char**)':
main.cpp:54: error: conversion from `SplashBitmap*' to non-scalar type `QByteArr
ay' requested
