GetEncoderClsid.rar_GDIplus 保存_GetEncoderClsid

记录该函数，方便以后查询。 int GetEncoderClsid(const WCHAR* format, CLSID* pClsid) { UINT num= 0; UINT size= 0; ImageCodecInfo* pImageCodecInfo= NULL; GetImageEncodersSize(&num, &size); if(size== 0) { return -1; } pImageCodecInfo= (ImageCodecInfo*)(malloc(size)); if(pImageCodecInfo== NULL) { return -1; } GetImageEncoders(num, size, pImageCodecInfo); for(UINT j=0; j< num; ++j) { if(wcscmp(pImageCodecInfo[j].MimeType, format)== 0) { *pClsid= pImageCodecInfo[j].Clsid; free(pImageCodecInfo); return j; } } free(pImageCodecInfo); return -1; } 该函数使用方法很方便，如下面的代码就分别获得5中图像编码器的CLSID CLSID encoderClsid GetEncoderClsid(L"image/png", &encoderClsid); //png GetEncoderClsid(L"image/bmp", &encoderClsid); GetEncoderClsid(L"image/gif", &encoderClsid); GetEncoderClsid(L"image/jpeg", &encoderClsid); GetEncoderClsid(L"image/tiff", &encoderClsid);
