#include "ltwrappr.h"
virtual L_INT LBitmap::ZoomBlur(uDim, uStress, CenterPt)
L_UINT uDim; |
/* amount of blur */ |
L_UINT uStress; |
/* blur intensity */ |
POINT CenterPt; |
/* center point */ |
Blurs the image along radial lines starting from the specified center point. This function is available in the Raster Pro and above toolkits.
Parameter |
Description |
uDim |
A value that represents the amount of the blur. |
uStress |
A value that represents the amount of the blur intensity. |
CenterPt |
POINT structure that contains the center point from which to blur the image. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The function will blur and zoom the image 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.
