For example, an original image is 499x487px and 72dpi and is scaled down to 10cm(as requested) in the output with a poor quality.I noticed that changing the resolution of the original image fixes the problem.If you have specified option prescaleImages=false (see below), then the problem comes from your image and not from XFC.What are the image conversion rules followed by XFC? Is there a way to fix the problem without changing the images directly?The following command-line options, imageResolution and prescaleImages, (these options have, of course, API equivalents) can be used to control the way XFC renders images. Excerpts from http://www.xmlmind.com/foconverter/_distrib/doc/user/command_line_java.html --- * imageResolution Default image resolution in DPI. A positive integer. Used to compute the intrinsic size of an image, but only when an image file does not contain resolution or absolute size information. Default value: 96. * prescaleImages Image scaling policy. true or false. Default: true. By default images are prescaled to minimize output document size. If the prescaleImages property is set to false the original size of images is preserved and scaling directives are inserted in the output document. The prescaleImages property is honored only for true raster graphics. Vector graphics (WMF, EMF) are never prescaled. Pre-rasterized vector graphics (SVG, MathML) are always prescaled (by the competent renderer, e.g. Batik or JEuclid, not by XMLmind XSL-FO Converter itself). --- Note that when an image file contains incorrect resolution information (which is often the case), there is currently no way to instruct XFC to ignore this information. The only way to fix the problem is to fix the image by changing the resolution information in the image file. |
