Looks at groups of black pixels and removes the outer edges. This effectively makes a speck or text character shrink or thin by the selected value. Setting Erode to 2 erodes a 3 by 3 block of pixels to a single central pixel, or make a 2 by 2 block of black pixels disappear entirely.
Erode has the effect of peeling off the outer layer of the character and is useful for thinning bold characters. Decrease this value if the characters are breaking up.
Negative values are not allowed with this feature.
