In the principle, the answer is: set the width attribute in the DITA source but do not use pixels, instead use a unit such as pc, pt, px, in, cm, mm, em. The problem is that we forgot to support these units[*] in the case of the XHTML output. We'll fix this omission in the next release. For now, the workaround is to save your PNG images with a resolution higher than 72dpi (which is FOP default). You may try 96dpi or even 120dpi. Using the Gimp (http://www.gimp.org/), this done by selecting menu item "Image|Print Size". --- [*] We have confused a "Length" in the HTML spec (http://www.w3.org/TR/html401/types.html#type-length) with a "Length" in the CSS spec (http://www.w3.org/TR/CSS2/syndata.html#value-def-length). -- XMLmind DITA Converter Support List [email protected] http://www.xmlmind.com/mailman/listinfo/ditac-support
