So I've written a limited Java EPS creator for image files using BufferedImage and Image I/O, but it's not perfect.
I need to determine if it's RGB, CMYK, or grayscale (including 1-bit B&W), get the bits per component, collect the samples in per-pixel sequence in a certain order (RGB not BGR), and write my EPS. Oh, and if there's an alpha channel, I need to get those values and handle them specially. Ascertaining type: BufferedImage#getColorModel#getColorSpace#getType works for CMYK, but for 1-bit B&W, it reports 8-bit RGB. BufferedImage#getType works for 1-bit B&W (BufferedImage.TYPE_BYTE_BINARY), but not for CMYK (BufferedImage.TYPE_CUSTOM). So already, I'm forced to use a different strategy for different kinds of images. Do I have the right idea? Accessing sample information with a ColorModel is easy. final Object reusableDataArray = raster.getDataElements(x, y, null) final int[] reusableSampleArray = colorModel.getComponents(sampleArray, null, 0); final int bitsPerComponent = colorModel.getComponentSize(0); Accessing sample information from a Raster/SampleModel (TYPE_BYTE_BINARY) isn't quite so easy. BufferedImage#getType provides enough information to interpret the output of Raster#getPixel, but that means I have to write new logic for each #getType. So right now, through trial and error I'm typing up a list of BufferedImage.TYPE_*s that work well with ColorModel, and handling them consistently. For each types that don't work well with ColorModel, I'm writing special logic to interpret Raster#getPixel. Am I on the right track, or am I just making this hard for myself? =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA2D-INTEREST".
