LBitmap::Cylindrical

#include "ltwrappr.h"

virtual L_INT LBitmap::Cylindrical (nValue, uType)

L_INT nValue;

/* stretch amount */

L_UINT uType;

/* cylinder type */

Warps the bitmap around a cylinder. This function is available in the Raster Pro and above toolkits.

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).

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.
