LBitmap::GlassEffect

Summary

Divides the bitmap into rectangular cells and makes it look as if it is being viewed through glass blocks.

Syntax

#include "ltwrappr.h"

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

Parameters

L_UINT 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.

L_UINT 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.

L_UINT 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

Value	Meaning
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.
