L_LTIMGSFX_API L_INT L_SpherizeBitmap(pBitmap, nValue, CenterPt, crFill, uFlags)
Warps the image around a 3D spherical shape.
Pointer to the bitmap handle that references the bitmap on which to apply the effect.
Amount of stretching where:
Valid values are range in between -500 and 500.
POINT structure that contains the center of the sphere.
The COLORREF value that specifies the fill color for any exposed areas.
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.
|FILL_CLR||[0x0000] Fill any exposed areas with
|FILL_RPT||[0x0001] Stretch the image edges to fill the exposed area.|
|FILL_NOCHG||[0x0002] Leave the exposed area as is, without changing it.|
|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.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
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 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 in the Document and Medical Imaging toolkits.
To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.
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.
