Remaps the bitmap pixels by applying a linear transformation described by a rescale slope and an intercept.
#include "l_bitmap.h"
L_LTIMGCOR_API L_INT L_ApplyLinearModalityLUT (pBitmap, fIntercept, fSlope, uFlags)
Pointer to the main bitmap handle.
Rescale intercept.
Rescale slope.
A flag that determine the behavior of the function, the user can use one or more flags of the following:
| Flags | Meaning |
|---|---|
| M_LUT_SIGNED | [0x0001] The LUT entries are signed |
| M_LUT_UPDATE_MIN_MAX | [0x0002] Update MinVal,MaxVal inside the bitmap handle |
| M_LUT_USE_FULL_RANGE | [0x0004] Do not mask the values in the LUT |
| M_LUT_ALLOW_RANGE_EXPANSION | [0x0008] Allow the function to increase pBitmap->HighBit (if needed) to be able to hold the data range after applying modality LUT. |
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
Win32, x64, Linux.
For an example, refer to L_ApplyModalityLUT.
