Здравствуйте Hollander, Вы писали:


H>Привет !

H>Встретил топик похожий, налабал решение попроще. Так можно сохранять хучь битмапы, хучь иконки, хучь метафайлы и вообще все объекты, поддерживающие IPicture. Написал на Cи — так круче.

даешь GDI+ в массы!!!

/// пример не в тему, зато позволяет сохранять в bmp,jpeg,gif,emf,tiff,png
/// содран с PlatformSDK/GDI+/Setting JPEG Compression Level
