L_ColorMergeBitmap

#include "l_bitmap.h"

L_LTIMGCLR_API L_INT L_ColorMergeBitmap(pBitmap, ppBitmap, uStructSize, uFlags)

pBITMAPHANDLE pBitmap;

pointer to the bitmap handle

pBITMAPHANDLE *ppBitmap;

bitmaps to be merged

L_UINT uStructSize;

size in bytes, of the structure pointed to by pBitmap

L_UINT uFlags;

type of separation

Creates a color bitmap by merging grayscale bitmaps that were created as color separations. You can use this to recombine the bitmaps that the L_ColorSeparateBitmap function creates.

Parameter Description
pBitmap Pointer to the bitmap handle referencing the target bitmap.
ppBitmap An array of pointers to the bitmap handles referencing the bitmaps to be merged.
uStructSize Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE).
  The pointers in the array should be in the appropriate order, which in most cases is the order of the letters in the name. For example, for CMY separation, the first pointer should be for the cyan plane, the second for magenta, and the third for yellow. The only exception is RGB, which should be in BGR (blue, green, red) order.
uFlags The type of separation that was used to create the grayscale images. Valid values are:
  Value Meaning
  COLORSEP_RGB [0x0000] Merge images from three RGB planes.
  COLORSEP_CMYK [0x0001] Merge images from four CMYK planes.
  COLORSEP_HSV [0x0002] Merge images from three HSV planes.
  COLORSEP_HLS [0x0003] Merge images from three HLS planes.
  COLORSEP_CMY [0x0004] Merge images from three CMY planes.
  COLORSEP_YUV [0x0005] Merge images from three YUV planes.
  COLORSEP_XYZ [0x0006] Merge images from three XYZ planes.
  COLORSEP_LAB [0x0007] Merge images from three LAB planes.
  COLORSEP_YCrCb [0x0008] Merge images form three YCrCb planes.
  COLORSEP_SCT [0x0009] Merge images form three SCT planes.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.

The supported color-space models are RGB, CMYK, CMY, HSV, HLS, YUV, XYZ, LAB, YCrCb and SCT.

If all the bitmaps of ppBitmap array are 16 bits grayscale bitmaps then the resulting bitmap is 48 bits per pixel, otherwise the resulting bitmap is 24 bits per pixel.

To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.

This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available in the Document and Medical Imaging toolkits.

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.
