L_GetMinMaxBits
#include "l_bitmap.h"
L_INT EXT_FUNCTION L_GetMinMaxBits(pBitmap, pLowBit, pHighBit)
|
pBITMAPHANDLE pBitmap; |
/* pointer to the bitmap handle */ |
|
/* address of a low bit variable to be updated */ | |
|
/* address of a high bit variable to be updated */ |
Returns the low and high bits of the values present in a 12 or 16-bit grayscale and 48 and 64-bit image. This function is available in the Document/Medical Toolkits only.

Parameter |
Description |
|
pBitmap |
Pointer to the bitmap handle of a 12-bit or 16-bit grayscale and 48 and 64-bit bitmap. |
|
pLowBit |
Address of a variable that will be updated with the lowest bit set in the bitmap. |
|
pHighBit |
Address of a variable that will be updated with the highest bit set in the bitmap. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The minimum and maximum bit values can be used to specify the range of useful bits and to create a lookup table, for use in L_WindowLevel or L_WindowLevelBitmap.
This function supports 12 and 16-bit grayscale. Support for 12 and 16-bit grayscaleimages is available only in the Document/Medical toolkits.
This function supports signed data images.

Example
This example gets the minimum and maximum bits for an image.
BITMAPHANDLE LeadBitmap; /* Bitmap handle of the image. */
L_INT L_FAR nLowBit; /* the low bit variable */
L_INT L_FAR nHighBit; /* the high bit variable */
/* get min/max bits */
L_GetMinMaxBits(&LeadBitmap, &nLowBit, &nHighBit);
