It dosn't sound right to try "increase resolution" from a lower resolution image. Otherwise we could take low resolution photos, and programatically make them high resolution. The "physics" just isn't right. When you try to do it, the program has to guess at filling in the higher resolution points, and the result is it looks worse.

Comment on Re: Image File Conversion Resolution using Image Magick
Thanks for your reply. I appreciate the point you make. However, as I belevie that the pdf file is a
vector orientated file, I was hoping that the restrictions you have to work with on pixel based files would not apply.
