Using objEncoderParam s when saving an image

[darrel]

I'm currently saving a JPG file as such:

imgOutput.Save( "path/filename.jpg", System.Drawing. Imaging.ImageFo rmat.Jpeg)

That saves the imgOutput as a JPG to the path shown.

Works fine.

Now, I'd like to change the JPG compression it uses. I apparently can do
that with an EncoderParamete r:

Dim objEncoderParam s As New EncoderParamete rs(1)
objEncoderParam s.Param(0) = New EncoderParamete r(Encoder.Quali ty, 500)
imgOutput.Save( "path/filename.jpg", *encoder*, objEncoderParam s)

What I'm stuck on is the 'encoder' value. What do I put there to? I assume I
need to tell it to use the JPG encoder, right? If so, I'm stuck on the
syntax.

Well, that leaves me with the same question, I think. The key line being:

bmp.Save(fileNa me, jpegCodecInfo, codecParams);

I'm stumped as to what the 'jpegCodecInfo' is. How do I set that?
