LBitmap::Cubism

#include "ltwrappr.h"

virtual L_INT LBitmap::Cubism(uSpace, uLength, nBrightness, nAngle, crColor,uFlags)

L_UINT uSpace;	/* cube spaces */
L_UINT uLength;	/* cube side length */
L_INT nBrightness;	/* brightness */
L_INT nAngle;	/* cube orientation */
COLORREF crColor;	/* background color */
L_UINT uFlags;	/* flags */

Remaps the bitmap into a collection of rotated rectangles (cubic faces) so that it appears to have been created in the Cubist art style. This function is available in the Raster Pro and above toolkits.

Parameter	Description
uSpace	Space between cubes, in pixels. As uSpace decreases the concentration of cubes increases and vice versa. The valid range is from 1 to the image or region dimension (that is, min(Height, Width))
uLength	Cube side length, in pixels.
nBrightness	A value that indicates the brightness of the bitmap. This value can be a number between -1000 and 1000. Negative values darken the image and positive values lighten the image.
nAngle	The cube’s angle of orientation, in hundredths of a degree (+/-). This value is ignored if the CUB_RAND flag has been set in uFlags. Possible values are from–36000 to 36000.
crColor	The COLORREF value that specifies the background color. This value is ignored if the CUB_BKG flag has been set in uFlags.
uFlags	Flags that indicate the background color, cube shape and cube orientation. You can use a bit wise OR (\|) to specify one flag from each group.
	The following are the flags that indicate the background color:
	Value	Meaning
	CUB_BKG	[0x0001] Use the image itself as the background.
	CUB_COLOR	[0x0002] Use the color in the crColor member as the background color.
	The following are the flags that indicate the cube’s shape:
	Value	Meaning
	CUB_SQR	[0x0010] Cubes will have square shape.
	CUB_RECT	[0x0020] Cubes will have rectangular shape.
	The following are the flags that indicate the cube’s orientation:
	Value	Meaning
	CUB_RAND	[0x0100] Cubes will have random orientation.
	CUB_ORNT	[0x0200] All cubes will have the orientation specified by the nAngle value.

Returns

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

Comments

This function remaps the bitmap into a collection of rotated rectangles (cubic faces), producing an image in a Cubist style. For an example, see the following figure:

$image\Cubism_before.gif$

The following figure shows the same bitmap, after the effect has been applied:

$image\Cubism_after.gif$

To obtain this effect, the following settings were used with the function:

uSpace = 5

uLength = 10

nBrightness = 0

nAngle = 0

crColor = RGB(0,0,0)

uFlags = CUB_BKG|CUB_RAND|CUB_RECT

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.
