Automatic raster control tools operate on the region selected. With the manual tools the user can change the raster image dimension. These tools remove speckles and stray marks, and enhance desired image elements by smoothing and rebuilding portions of horizontal and vertical lines, filling in gaps in imperfect raster images. Raster Image Control Functions Light Filter Filter Smoothes and rebuilds edges of lines and solids. Despeckle Removes speckles from the image.
Speckle size is user definable.
