PNG to BMP with white background Topic is solved

[cutecode]

Why do I get black background instead of white background

Code: Select all

	wxString x1 = L"c:\\tmp\\1.png";
	wxString x2 = L"c:\\tmp\\2.bmp";
	
	wxImage im;
	im.LoadFile(x1, wxBITMAP_TYPE_PNG);
	
	im.Replace(im.GetMaskRed(), im.GetMaskGreen(), im.GetMaskBlue(), 255, 255, 255);

	im.SaveFile(x2, wxBITMAP_TYPE_BMP);

Thank you

That png has an alpha channel, try calling wxImage::ConvertAlphaToMask() first.
