L_LTIMGSFX_API L_INT L_GlassEffectBitmap(pBitmap, uCellWidth, uCellHeight, uFlags)
Divides the bitmap into rectangular cells and makes it look as if it is being viewed through glass blocks.
Pointer to the bitmap handle referencing the bitmap to be changed.
Value that represents the width of a cell in pixels or the number of cells present across the width of the bitmap, based on the flags set in
uFlags. The valid range is between 2 and half the bitmap width.
Value that represents the height of a cell in pixels or the number of cells present across the height of the bitmap, based on the flags set in
uFlags. The valid range is between 2 and half the bitmap height.
Flags that indicate what type of data is in the
uCellHeight parameters. You can use a bitwise OR (|) to specify one flag from each group.
|GLASS_WFRQ||[0x0001] The parameter uCellWidth is the number of cells along the width of the bitmap.|
|GLASS_WPER||[0x0002] The parameter uCellWidth is the width of the cell in pixels.|
|GLASS_HFRQ||[0x0010] The parameter
|GLASS_HPER||[0x0020] The parameter
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
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.
If the bitmap has a region, the effect will be applied on the region only.
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.
To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.
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.
Required DLLs and Libraries
The following example loads a bitmap and applies a glass effect to it:
BITMAPHANDLE LeadBitmap; /* Bitmap handle to hold the loaded image. */
/* Load the bitmap, keeping the bits per pixel of the file */
nRet = L_LoadBitmap(MAKE_IMAGE_PATH(TEXT("Image1.cmp")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
/* apply glass effect */
nRet = L_GlassEffectBitmap(&LeadBitmap, 20,10, GLASS_WFRQ | GLASS_HPER );
nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.BMP")), &LeadBitmap, FILE_BMP, 24, 0, NULL);
