LBitmap::Fragment
#include "ltwrappr.h"
L_INT LBitmap::Fragment(uOffset, uOpacity)
L_UINT uOffset; |
/* image displacement */ |
L_UINT uOpacity; |
/* transparency percentage */ |
Averages a bitmap with its shifted copies. This function is available in the Raster Pro and above toolkits.
Parameter |
Description |
uOffset |
Value that indicates the number of pixels the copied image is shifted. |
uOpacity |
Value that indicates the transparency, in percent, of the copy in comparison to the original image. Possible values range from 0 to 100. A value of 0 means the resulting image will be black. A value of 100 means that each copy's value will comprise 25% of the result. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
This function creates four copies of an image. Each copy is shifted by the offset amount into one of the four directions: top, left, bottom and right. Then the bitmap is averaged with its shifted copies.
Use the LBitmap::DisplaceMap function to displace a bitmap's pixels horizontally and vertically according to the values of the displacement map image.
Use the LBitmap::Offset function to shift a bitmap's pixels horizontally and vertically.
Use the LBitmapRgn::Offset function to move a bitmap region by the specified number of rows and columns.
This function can process the whole image or a region of the image. If a bitmap has a region, the effect is applied only to the region.
Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
To update a status bar or detect a user interrupt during execution of this function, refer to LBase::EnableStatusCallback.
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.
