LBitmap::SmoothEdges
Summary
Smooths the rough edges in the image.
Syntax
#include "ltwrappr.h"
virtual L_INT LBitmap::SmoothEdges(nAmount, nThreshold, uFlags = 0)
Parameters
L_UINT nAmount
This is a percentage value that indicates blur size. 0 means no blurring and 100 means total blurring.
L_UINT nThreshold
Threshold value used to determine which pixels are edge pixels. If the difference determined for a pixel is greater than this value, the pixel is an edge. Valid values ranges are:
- 0 to 65535 for 64-bit, 48-bit and 16-bit grayscale images.
- 0 to 4095 for 12-bit grayscale images.
- 0 to 255 for otherwise.
L_UINT32 uFlags
Reserved for future use. Must be 0.
Returns
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
Comments
This function performs edge detection, then smooths those edges that are found. The other points of the image are unchanged.
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.
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.
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.
