Hi, I'm saving some images to JPEG via the .NET Image class. The problem is that when I want to set my own compression rate.
The code online says you can do that like thus;
bmp.Save(fileName, jpegCodecInfo, codecParams);
And to get the jpegCodecInfo you need to do this;
mimeType = "image/jpeg";
ImageCodecInfo GetEncoderInfo(string mimeType)
{
int j;
ImageCodecInfo[] encoders;
encoders = ImageCodecInfo.GetImageEncoders();
for(j = 0; j < encoders.Length; ++j)
{
if(encoders[j].MimeType == mimeType)
return encoders[j];
}
return null;
}
Now, when I try to compile the C++ version of this I get an error in Visual Studio.NET which complained about the type of variable I use for the ImageCodecInfo[] array:
Texture.cpp: error C2691: 'unsigned char __gc[]' : invalid type for __gc array element
This didn't make any sense
at all, so after some further examination I found myself looking on a page where they explained this was an error with C++ and jaggered arrays and that it would be resolved in the next version of Visual Studio.NET.
However, since I do not want to buy a new version for this I wondered if someone could help me out either with an solution or with a simple compiled codefile in which this function is written (in any language I can use from C++).
In await of your replies ;)
