* FUNCTIONS
|
|
|
29 |
* mlib_ImageChannelExtract - Copy the selected channels of the source
|
|
|
30 |
* image into the destination image
|
|
|
31 |
*
|
|
|
32 |
* SYNOPSIS
|
|
|
33 |
* mlib_status mlib_ImageChannelExtract(mlib_image *dst,
|
|
|
34 |
* mlib_image *src,
|
|
|
35 |
* mlib_s32 cmask);
|
|
|
36 |
* ARGUMENT
|
|
|
37 |
* dst Pointer to destination image.
|
|
|
38 |
* src Pointer to source image.
|
|
|
39 |
* cmask Source channel selection mask.
|
|
|
40 |
* The least significant bit (LSB) is corresponding to the
|
|
|
41 |
* last channel in the source image data.
|
|
|
42 |
* The bits with value 1 stand for the channels selected.
|
|
|
43 |
* If more than N channels are selected, the leftmost N
|
|
|
44 |
* channels are extracted, where N is the number of channels
|
|
|
45 |
* in the destination image.
|
|
|
46 |
*
|
|
|
47 |
* RESTRICTION
|
|
|
48 |
* The src and dst must have the same width, height and data type.
|
|
|
49 |
* The src and dst can have 1, 2, 3 or 4 channels.
|
|
|
50 |
* The src and dst can be either MLIB_BYTE, MLIB_SHORT, MLIB_INT,
|
|
|
51 |
* MLIB_FLOAT or MLIB_DOUBLE.
