Bug in JAI with transparent gif

[Martijn Houtman]

In JAI there is a bug when a transparent gif is converted to jpeg (happens probably with other formats too). I solved the bug in convertJAI.java by changing the image to RGB mode when necessary.           if (! (format.equals("gif") || format.equals("png")) &&             img.getColorModel()instanceof IndexColorModel) {           IndexColorModel icm = (IndexColorModel) img.getColorModel();           if (icm.getTransparency() == Transparency.BITMASK) {             byte[][] data = "" byte[3][icm.getMapSize()];             icm.getReds(data[0]);             icm.getGreens(data[1]);             icm.getBlues(data[2]);             LookupTableJAI lut = new LookupTableJAI(data);             img = JAI.create("lookup", img, lut);             log.debug("palette-color image converted to RGB");           }         }   I added also a gif encoder to convertJAI.java, so now JAI works well with gif's. Because I am not able to change the MMBase code I will send everything to Daniel Ockeloen, who is the author of convertJAI.java.   Martijn Houtman
