I create a bitmap from bytes coming via the web and when I downsample it, the resulting Jpeg is still too big even though I use small pixel format.
Does someone know how to manipulate the compression of the image? I had the impression that the saved image is no longer compressed.
You did not mention in your original post how you are saving your Jpeg. MSDN has a short page on setting compression here.
I hope I have not misunderstood the question.
