Hi Jeremias, Thanks for your valid suggestions. Does 0.95 supports for 16 and 32 bit images? What about the previous versions before 0.95? If you have a higher version can I get the algorithm or the code?
Thanks Harshini. -----Original Message----- From: Jeremias Maerki [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 13, 2008 12:36 PM To: [email protected] Subject: Re: Bitmap support in BmpImage.java class ? Sure, you can. Either you replace BmpImage with the JAI implementation as discussed earlier or you change BmpImage. In the latter case, you have to convert the 16 and 32 bit image data to 24 bit RGB. Otherwise, the renderers will not process the image data correctly (FOP Trunk is much more flexible here). For this you need to know a few things about the BMP format. Start here to get more information: http://en.wikipedia.org/wiki/BMP_file_format I think it's probably easiest if you use ImageIO or JAI to load BMP images and convert them to the required 24bit pixel stream using the BufferedImage.getRGB() method as done in JAIImage. But if I were you I'd try to upgrade FOP at least as soon as 0.95 is available next month.
