save a jpg as 8 bit grayscal

[cmarmr]

here is a code snip i am using but when i save a jpg with this code it is 24 bit grayscale saveJpeg(file1,img,8); private void saveJpeg(string path, Bitmap img, long quality) { // Encoder parameter for image quality EncoderParameter qualityParam = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, quality); // Jpeg image codec ImageCodecInfo jpegCodec = this.getEncoderInfo("image/jpeg"); if (jpegCodec == null) return; EncoderParameters encoderParams = new EncoderParameters(1); encoderParams.Param[0] = qualityParam; img.Save(path, jpegCodec, encoderParams); } private ImageCodecInfo getEncoderInfo(string mimeType) { // Get image codecs for all image formats ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders(); // Find the correct image codec for (int i = 0; i < codecs.Length; i++) if (codecs[i].MimeType == mimeType) return codecs[i]; return null; }

Thanks, Chad Aiena

Lol I think this piece of code is funny:

// Find the correct image codec
for (int i = 0; i < codecs.Length; i++)
if (codecs[i].MimeType == mimeType)
return codecs[i];
return null;
}

You can better rewrite it like this:

if(codecs.Length >= 1)
{
if(codecs[0].MimeType == mimeType)
return codecs[0];
return null;
}

But what is your question exactly?
