In our application we use PD4ML to generate PDF previews. In one such case, we also have images inside the document. The image is rendered correctly on HTML preview but does not renders correctly on PDF preview.
Please see attach generated html code and PDF preview. Look at the image under GAP column
Obviously the only problem is the original image dimensions. The image itself is too small and Acroread’s image scaling routines cannot produce anything acceptable from it.
Unfortunately from PDF we cannot choose applied image scaling algorithm. The only available PDF option is to force to interpolate the image, which usually gives even worse result (when applied to tiny images).
