 com.sun.media.jai.opimage.XorConstOpImage
| XorConstOpImage | | final class XorConstOpImage extends ColormapOpImage (Code) | | An OpImage implementing the "XorConst" operation.
This OpImage logically "xors" the pixels of a rendered
image with a set of constants, one for each band of the source image.
The destination pixel values are calculated as:
for (int h = 0; h < dstHeight; h++) {
for (int w = 0; w < dstWidth; w++) {
for (int b = 0; b < dstNumBands; b++) {
if (constants.length < dstNumBands) {
dst[h][w][b] = srcs[h][w][b] ^ constants[0];
} else {
dst[h][w][b] = srcs[h][w][b] ^ constants[b];
}
}
}
}
