LBitmap::Spherize
#include "ltwrappr.h"
virtual L_INT LBitmap::Spherize(nValue, CenterPt, crFill, uFlags)
| L_INT nValue; | /* stretch amount */ | 
| POINT CenterPt; | /* sphere center */ | 
| COLORREF crFill; | /* fill color */ | 
| L_UINT uFlags; | /* flags */ | 
Warps the image around a 3D spherical shape. This function is available in the Raster Pro and above toolkits.
| Parameter | Description | |
| nValue | Amount of stretching where : | |
| 
 | Positive values: stretch the central pixels toward the edges. | |
| 
 | Negative values: stretch the pixels toward the Center. | |
| 
 | Valid range is –500 to 500. | |
| CenterPt | POINT structure that contains the center of the sphere. | |
| crFill | The COLORREF value that specifies the fill color for any exposed areas. | |
| uFlags | Flags that indicate how to handle exposed areas outside the sphere and inside the sphere. You can use a bitwise OR (|) to specify one flag from each group. | |
| 
 | The following are the flags that indicate how to handle exposed areas outside the sphere: | |
| 
 | Value | Meaning | 
| 
 | FILL_CLR | [0x0000] Fill any exposed areas with crFill. | 
| 
 | FILL_RPT | [0x0001] Stretch the image edges to fill the exposed area. | 
| 
 | FILL_NOCHG | [0x0002] Leave the exposed area as is, without changing it. | 
| 
 | The following are the flags that indicate how to handle exposed areas inside the sphere: | |
| 
 | Value | Meaning | 
| 
 | FILL_ROT | [0x0000] Rotate the image inside the sphere pattern. | 
| 
 | FILL_WOUTROT | [0x0010] Fill exposed sphere pattern center as selected from exposed area process type flag. | 
| 
 | This flag is ignored if the nValue is negative. | |
Returns
| SUCCESS | The function was successful. | 
| < 1 | An error occurred. Refer to Return Codes. | 
Comments
This function will warp the image as a 3D spherical shape around the specified CenterPt. The center point must be defined inside the bitmap or inside the region, if the bitmap has a region.
If the bitmap has a region, the effect will be applied on the region only.
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.
