Selecting areas to keep or discard
A pair of brushes for keeping and discarding is used to "paint" areas on your
active layer. The tools are called Keep Brush and Discard Brush, and are either
used independently or, more typically, in combination with each other. When
using either tool, the brush paints an area contained by an outline which is
considered to be retained or discarded (depending on brush type). A
configurable number of pixels adjacent to the outline area are blended.
To select areas for keeping/discarding:
1. In Cutout Studio, click either Keep Brush Tool or Discard
Brush Tool from the left of the Studio workspace.
2. (Optional) Pick a Brush size suitable for the area to be worked on.
3. (Optional) Set a Grow tolerance value to automatically expand the
selected area under the cursor (by detecting colours similar to those within
the current selection). The greater the value the more the selected area will
grow.
4. Using the circular cursor, click and drag across the area to be retained or
discarded (depending on Keep or Discard Brush Tool selection). It's OK to
repeatedly click and drag until your selection area is made.
The Undo button reverts to the last made selection.
To fine-tune your selection, you can switch between Keep and
Discard brushes by temporarily holding down the Alt key.
5. Click OK to create your cutout.
You'll now see your active layer with the selected areas cut away (made
transparent).
Click Reset if you want to revert your selected areas and start
your cutout again.
