LBitmap::GlassEffect

#include "ltwrappr.h"

virtual L_INT LBitmap::GlassEffect(uCellWidth, uCellHeight, uFlags)

L_UINT uCellWidth;	/* cell width */
L_UINT uCellHeight;	/* cell height */
L_UINT uFlags;	/* flags */

Divides the bitmap into rectangular cells and makes it look as if it is being viewed through glass blocks. This function is available in the Raster Pro and above toolkits.

Parameter	Description
uCellWidth	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.
uCellHeight	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.
uFlags	Flags that indicate what type of data is in the uCellWidth and uCellHeight parameters. You can use a bitwise OR (\|) to specify one flag from each group.
	The following are the flags that indicate the type of data in the uCellWidth parameter:
	Value	Meaning
	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.
	The following are the flags that indicate the type of data in the uCellHeight parameter:
	Value	Meaning
	GLASS_HFRQ	[0x0010] The parameter uCellHeight is the number of cells along the height of the bitmap.
	GLASS_HPER	[0x0020] The parameter uCellWidth is the height of the cell in pixels.

Returns

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

Comments

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 only in the Document/Medical toolkits.

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

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.

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.
