Whilst its true that Java changed the implementation and that's what causes the slowdown, FOP still elects to use that particular JDK library. Luis has been working on a raw PNG Image Loader that addresses a couple of performance issues. The idea of the new loader is that it doesn't use the JDK library. I would like to leave it open and when Luis returns from vacation in a couple of days he can test out his new raw PNG handler to see if it alleviates this particular performance issue.

https://issues.apache.org/bugzilla/show_bug.cgi?id=51149 --- Comment #1 from patc...@portaildulibre.fr 2011-06-15 13:31:15 UTC --- Hello, I have a similar bug (fop 1.0), but it doesn't appear in the version 1.3 of xmlgraphics (fop 0.95). The problem comes from color model associated with the image. * if is_sRGB_stdStale = true then getRBG method is very fast * if is_sRGB_stdStale = false then getRBG is slow because the treatment is delegated to ICC_ColorSpace.toRGB The color model is correct, but it is modified by the class org.apache.xmlgraphics.image.loader.impl.imageio.ImageLoaderImageIO by the following code (v 1.4): if (providerIgnoresICC && cm instanceof ComponentColorModel) { // Apply ICC Profile to Image by creating a new image with a new // color model. ICC_Profile iccProf = tryToExctractICCProfile(iiometa); if (iccProf != null) { ColorModel cm2 = new ComponentColorModel( new ICC_ColorSpace(iccProf), cm.hasAlpha(), cm .isAlphaPremultiplied(), cm .getTransparency(), cm.getTransferType()); WritableRaster wr = Raster.createWritableRaster(imageData .getSampleModel(), null); imageData.copyData(wr); BufferedImage bi = new BufferedImage(cm2, wr, cm2 .isAlphaPremultiplied(), null); imageData = bi; cm = cm2; I removed this code and it works fine now, but it's dirty. Until a fix, best regards. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.
