| 29 | * FUNCTION |
| 30 | * mlib_ImageLookUp - table lookup |
| 31 | * |
| 32 | * SYNOPSIS |
| 33 | * mlib_status mlib_ImageLookUp(mlib_image *dst, |
| 34 | * const mlib_image *src, |
| 35 | * void **table) |
| 36 | * |
| 37 | * ARGUMENT |
| 38 | * dst Pointer to destination image. |
| 39 | * src Pointer to source image. |
| 40 | * table Lookup table. |
| 41 | * |
| 42 | * DESCRIPTION |
| 43 | * The mlib_ImageLookUp function performs general table lookup on an |
| 44 | * image. The destination image is obtained by passing a source image |
| 45 | * through a lookup table. |
| 46 | * |
| 47 | * The source image may be 1-, 2-, 3-, or 4-channeled of data types |
| 48 | * MLIB_BIT, MLIB_BYTE, MLIB_SHORT, or MLIB_INT. The lookup table may be |
| 49 | * 1-, 2-, 3-, or 4-channeled of data types MLIB_BYTE, MLIB_SHORT, MLIB_INT, |
| 50 | * MLIB_FLOAT, or MLIB_DOUBLE. The destination image must have the same |
| 51 | * number of channels as either source image or the lookup table, |
| 52 | * whichever is greater, and the same data type as the lookup table. |
| 53 | * |
| 54 | * It is the user's responsibility to make sure that the lookup table |
| 55 | * supplied is suitable for the source image. Specifically, the table |
| 56 | * entries cover the entire range of source data. Otherwise, the result |
| 57 | * of this function is undefined. |
| 58 | * |
| 59 | * The pixel values of the destination image are defined as the following: |
| 60 | * |
| 61 | * If the source image is single-channeled and the destination image is |
| 62 | * multi-channeled, then the lookup table has the same number of channels |
| 63 | * as the destination image: |
| 64 | * |
| 65 | * dst[x][y][c] = table[c][src[x][y][0]] |
| 66 | * |
| 67 | * If the source image is multi-channeled and the destination image is |
| 68 | * multi-channeled, with the same number of channels as the source image, |
| 69 | * then the lookup table will have the same number of channels as |
| 70 | * the source image: |
| 71 | * |
| 72 | * dst[x][y][c] = table[c][src[x][y][c]] |
