Hi,
I have another question regarding the creation of a buffered
image. I used ur idea for a gray scale image and it worked fine.
Now I have a colored image, not a gray scale image. I want to
create a bufferedImage frm the data. I did not really understand
what a "band" and "bank" refers to described in the API for
creating a raster.
Here I am attaching a sample piece of code....
cs = ColorSpace.getInstance(ColorSpace.CS_sRGB);
cm = new ComponentColorModel(cs, new int[]{8, 8, 8}, false, false,
Transparency.OPAQUE, DataBuffer.TYPE_BYTE);
int[] band = new int[]{0};
db = new DataBufferByte(readSlice(i, slicesize), texturewidth *
textureheight * 3); // readSlice method reads an RGB image into a
byte array and returns it
raster = WritableRaster.createInterleavedRaster(db, texturewidth,
textureheight, texturewidth * 3, 3, band, null);
img = new BufferedImage(cm, raster, true, null);
Following is the exception I am getting...
Exception in thread "main" java.lang.IllegalArgumentException:
Raster ByteInterleavedRaster: width = 128 height = 128
#numDataElements 1 dataOff[0] = 0 is incompatible with ColorModel
ColorModel: #pixelBits = 24 numComponents = 3 color space =
java.awt.color.ICC_ColorSpace@5fafd1 transparency = 1 has alpha =
false isAlphaPre = false

Could u please give me some suggestions...
Thanks,
