Java graphics manipulation

Post #174,847 by ChrisR 9/17/04 5:25:03 PM Reply	Java graphics manipulation Coming up on my weekend project and I need to get some Java code that views and manipulates PBM formatted graphics. Specifically, I need a program where I can merge two long PBM images together (picking the x,y coordinate of the second image to merge into the first). Any suggestions on Java libraries/routines that would be good starting point for such a project. Thanks.

ImageIO.write outputs the result. BufferedImage i1 = ImageIO.read(stream1);\nBufferedImage i2 = ImageIO.read(stream2);\ng2 = i1.getGraphics();\ng2.drawImage(i2, null, x, y);\nImageIO.write(i1, "pbm", outputStream); Supposedly the JAI Image I/O Tools supports PBM.

The conversion is mostly automatic though I had to run an XOR (^) on all the bytes because pbm is inverted from bitmap. And, for some stupid reason, the bitmap images are upside down (starting from bottom left). Anyhow, once in .bmp format, the options are a little more amenable.
