LBitmap::Cylindrical

#include "ltwrappr.h"

virtual L_INT LBitmap::Cylindrical (nValue, uType, uFlags = 0)

L_INT nValue;	/* stretch amount */
L_UINT uType;	/* cylinder type */
L_UINT32 uFlags;	/* flags */

Warps the bitmap around a cylinder.

Parameter	Description
nValue	Amount of stretching where :
	Positive values: stretch the pixels toward the bitmap edges depending on the type of cylinder.
	Negative values: stretch the pixels toward the central line of the cylinder.
	The valid range is from 100 to 100.
uType	A value that indicates the cylinder shape. Possible values are:
	Value	Meaning
	CYL_HORZ	[0x0000] Stretch the pixels along the vertical plane (horizontal cylinder).
	CYL_VERT	[0x0001] Stretch the pixels along the horizontal plane (vertical cylinder).
uFlags	Reserved for future use. Must be 0.

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 only to the region.

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.

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.
