Well, I have done this only for jpeg images and for fo:external-graphic right now, against the fop-20.4 release sources. I have changed the image classes to support dpi. And set that to the default 72 dpi for now. Only for jpeg am I setting the real dpi from the file. But I have seen at various places where the 72 dpi is kinda hard coded into the code. The modification that I have done right now solves my purpose, but I suppose I will also need to add support for this in TIFF images and PNG sometime sooner. Who is the maintainer of these classes, and how do i submit a patch. I am using windows, so what tools will i require?
