The conversion of SVG to PNG is performed by the Batik plug-in. * I don't think that parameter dpi may be used to control the size of the PNG file generated out of the SVG file. See http://www.xmlmind.com/xmleditor/addons_doc.html#batik_imagetoolkit * It seems that an SVG file has dimensions in *pixels* and that these dimensions in pixels are used when creating the PNG file. Example: XXE_install_dir/demo/graphics/tux.svg: --- <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Sodipodi ("http://www.sodipodi.com/";) --> <svg ... version="1.0" x="0" y="0" width="744.094" height="744.094" ... --- Batik indeed converts tux.svg to a .png file which is 744x744pixels. I've checked this. I think your problem comes from the fact that either your SVG files have no width and height attributes (Batik uses 400x400 as a default) or the values of these attributes are very small. If I use Inkscape to change the dimensions of my SVG file (without changing the graphics) to say, width="30" and height="30", I get a very low quality image in the EPUB file. -- XMLmind XML Editor Support List [email protected] http://www.xmlmind.com/mailman/listinfo/xmleditor-support
