L_LTIMGCOR_API L_INT L_ApplyLinearModalityLUT (pBitmap, fIntercept, fSlope, uFlags)

pBITMAPHANDLE pBitmap;	/* pointer to the main bitmap handle */
L_DOUBLE fIntercept;	/* rescale intercept */
L_DOUBLE fSlope;	/* rescale slope */
L_UINT uFlags;	/* flags */

Remaps the bitmap pixels by applying a linear transformation described by a rescale slope and an intercept.

Parameter

Description

pBitmap

Pointer to the main bitmap handle.

fIntercept

Rescale intercept

fSlope

Rescale slope

uFlags

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.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

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.
