The destination image is obtained by passing a source image * through a lookup table. * * The source image may be 1-, 2-, 3-, or 4-channeled of data types * MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT. The lookup * table may be 1-, 2-, 3-, or 4-channeled of data types MLIB_BYTE, * MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE. * The destination image must have the same * number of channels as either source image or the lookup table, * whichever is greater, and the same data type as the lookup table. * * It is the user's responsibility to make sure that the lookup table * supplied is suitable for the source image. Specifically, the table * entries cover the entire range of source data. Otherwise, the result * of this function is undefined. * * The pixel values of the destination image are defined as the following: * * If the source image is single-channeled and the destination image is * multi-channeled, then the lookup table has the same number of channels * as the destination image: * * dst[x][y][c] = table[c][src[x][y][0]] * * If the source image is multi-channeled and the destination image is * multi-channeled, with the same number of channels as the source image, * then the lookup table will have the same number of channels as * the source image: * * dst[x][y][c] = table[c][src[x][y][c]] */ #include "mlib_image.h" #include "mlib_ImageCheck.h" #include "mlib_ImageLookUp.h" #include "mlib_c_ImageLookUp.h" /***************************************************************/ JNIEXPORT mlib_status mlib_ImageLookUp(mlib_image *dst, const mlib_image *src, const void **table) { mlib_s32 slb, dlb, xsize, ysize, nchan, ichan, bitoff_src;
