LBitmap::Cubism

#include "ltwrappr.h"

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

Remaps the bitmap into a collection of rotated rectangles (cubic faces) so that it appears to have been created in the Cubist art style.

Parameters

L_UINT 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))

L_UINT uLength

Cube side length, in pixels.

L_INT 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.

L_INT nAngle

The cubes 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.

COLORREF crColor

The COLORREF value that specifies the background color. This value is ignored if the CUB_BKG flag has been set in uFlags.

L_UINT 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 cubes 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 cubes 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

Value Meaning
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.

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.

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.
