I was looking at issues related to images not being displayed with their correct resolution. As far as I understand all image formats apart from GIF (which defaults to 72dpi) do carry resolution information. However, it only works for JPEG at the moment. I managed to fix it for BMP images by reading / interpreting the appropriate header fields. TIFF and PNG are more complicated as the information is buried in the file so you actually have to load the image to get to the information. Both TIFF and PNG are currently implemented using BatikImage. However, it appears that the Batik decoder doesn't make the resolution information available. At least its not set in BatikImage.loadImage() and I couldn't find a field in the org.apache.batik.ext.awt.image.rendered.CachableRed class which looks like holding the x and y resolutions.
Any one knows how to get to the resolution settings for the Batik images? Thanks Manuel
