Set bit depth of an image

Hi. I haven't been able to get an answer in the vb newsgroup on the topic,
so I'll try here. I'm converting .tif images into other image formats like
..jpeg and .gif and I need to know how I can control the bit depth of these
images. The System.Drawing.Image object's default bit depth when saving
images seems to be 24 for .jpeg and 8 for .gif.

Thanks,
Shawnuse CxImage library, better than .nets...
