Hello,
All alpha bitmaps are premultiplied by defaut to increase loading speed. If you don't use premultiplied bitmaps you can manually patch CXTPOffice2007Image::LoadFile method and add Premultiply() method call in the end of file. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

| If I want to use premultiplied images, what software I should use for correct transparency in Ribbon Sample? |

Thanks Oleg. Work's. Adobe Photoshop hides alfa-chanal during re-saveing png file. I'l save image in tiff-format with option "Saving transparency" and then covert it to png with Ms Office Paint Manager, that save's alfa-chanal. And...It's work too. |
