Remarks
Despeckle is the process of removing random specks of noise from an image. This method examines the current image to find objects meeting the current criteria for specks and then removes them. If no parameters are provided, the defaults are used.
Output
- ImagXpress validates the input, detects the specks, removes them and returns results from the process. If the operation fails, the current image is unchanged. If no errors occur, ImagXpress despeckles the current image. If the despeckle operation is not performed for any reason, the current image is not modified.
- IPImageWasModified is set to True if the image was modified, and False if image was not modified.
