On function
void ImageSysData::Paint(SystemDraw& w, int x, int y, const Rect& src, Color c);
Search for
if(!himg) {
LTIMING("Image Alpha create");
BitmapInfo32__ bi(sz.cx, sz.cy);
himg = CreateDIBSection(ScreenHDC(), bi, DIB_RGB_COLORS, (void **)§ion, NULL, 0);
Copy(section, ~img, img.GetLength());
}
Sometimes CreateDIBSection fails. Is rare, but it does happen returning 0 in the process, which causes the Copy function to crash the application.
Propose to change with.
if(!himg) {
LTIMING("Image Alpha create");
BitmapInfo32__ bi(sz.cx, sz.cy);
himg = CreateDIBSection(ScreenHDC(), bi, DIB_RGB_COLORS, (void **)§ion, NULL, 0);
ASSERT(himg); // Assert on debug
if(!himg) {
return; // Return on release.
}
Copy(section, ~img, img.GetLength());
}
