如何判断jpg图片是RGB模式还是CMYK模式?
------解决方案--------------------------------------------------------
public static bool IsCMYK(System.Drawing.Image img)
{
bool isCmyk;
if ((GetImageFlags(img).IndexOf( "Ycck ") > -1) || (GetImageFlags(img).IndexOf( "Cmyk ") > -1))
{ isCmyk = true; }
else
{ isCmyk = false; }
return isCmyk;
}
