JPG Compression

[Chris Mcilvoy]

I am using code from
http://support.microsoft.com/default.aspx?scid=kb;en-
us;324790 to no avail.

private static 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;
}
private void SaveJPGWithCompressionSetting( Image image,
string szFileName, long lCompression )
{
EncoderParameters eps = new EncoderParameters(1);
eps.Param[0] = new EncoderParameter( Encoder.Quality,
lCompression );
ImageCodecInfo ici = GetEncoderInfo("image/jpeg");
image.Save( szFileName, ici, eps );
}
 

it creates a new image ,but it does not compress the
quality of the image at all. is there something else i
could be missing?
thanks
