Use this dialog box to access the different filter types.

You can use these filters in conjunction with other cleanup options, such as
Despeckle and Deskew.

Smooth

Removes unnecessary pixels from the edges of raster objects, fills holes in
raster lines, and removes speckles from the raster image.

Thin

Trims raster objects by one pixel (per pass) in the directions you specify.

Thicken

Thickens the edges of raster objects by one pixel (per pass) in the directions
you specify.

Separate

Separates raster lines that are partially merged to prevent Raster Design from
converting them into one thick line.

Skeletonize

Thins all raster data to a thickness of one pixel.

Number of Passes

Specifies the number of times the filter runs. For example, a pass value of
3 is equivalent to running the filter 3 times.

Horizontal

Specifies that the filter follows in a horizontal direction.

Vertical

Specifies that the filter follows in a vertical direction.

Diagonal

Specifies that the filter follows in a diagonal direction.
