Expanding and contracting editable areas

You can add parts to and remove parts from an editable area.

By default, each editable area that you define replaces the last one defined. However, you can use the following mask modes if you want to retain the current editable area but modify its shape:

A mask mode remains active until you change modes. The following examples illustrate the use of the different mask modes.

Removing protected areas

You can remove protected areas from within an editable area. This feature is useful for modifying color masks that have large editable areas.

Specifying number of pixels

You can expand and contract an editable area by a specific number of pixels. The pixels are added to or removed from the edge of the editable area.

Adding pixels of similar color

You can add adjacent pixels of a similar color to an editable area. The editable area expands until it reaches pixels with colors that are too dissimilar from the colors in the original editable area. The color tolerance value you specify sets the percentage of color variation allowed between the pixels in the original editable area and the adjacent protected areas.

You can also add all pixels of similar color to an editable area regardless of whether they are adjacent to those in the current editable area. The color tolerance value you specify sets the percentage of color variation allowed between the pixels in the original editable areas and the protected areas.
