Re: Problem with FOP when generating a PNG
Hi Peter, I looked after the scale factor in the paint method of my Graphics2DImagePainter. When I export in pdf/ps, the scale factor is 1 and when I export in PNG, it's 1/1000. I saw that in Java2DPainter class the fonts are scaled by 1000 when used in drawText. In my mind you should do the same thing for drawImage. I made some tests and all is ok for me (and my plugin). What's your opinion ? Calixte Le jeudi 04 novembre 2010 à 13:09 +, Peter Hancock a écrit : Hi Calixte, Where you able to replicate the issue without integration with your plugin?

Maybe I made some errors in my code, but it's weird that all is fine with pdf output and not with png output. The paint method in the class Graphics2DImagePainterJLaTeXMath.java is called, I tryed to make a simple g2d.setColor(Color.RED);g2d.fill(rect2d) rather than to paint my icon and in the pdf I got filled red rect. but not in png. I know the difficulties met to debug a foreign code, so if I could help you, don't hesitate. Did you manage to compile jlatexmath and the fop plugin ?
