> In investigating a problem in the display of PNG images in FOP, I discovered
> that image processing was really slow.
> Examining the code in a debugger the surprise is that the source of slowness
> is
> not the rendering of the image (which is done through Java’s JAI) but in the
> steps leading up to the rendering of the image.
> For a simple FO page, with a single PNG image FOP takes 90 seconds. Remove
> the
> image and FOP takes 1 second. RenderX takes a second as well with our without
> the image.
> So the addition of a single image to an FO page results in extreme slowness –
> two orders of magnitude slower than RenderX XEP.
