The Image Display
The Fluid Mask displays your image in one of three views (accessed by
the tabs along the top of the image):
- Source: The
Source view shows the original image.
- Workspace:
The Workspace view is where you create the cut-out masks.
- Cut-out:
The Cut-out view shows the cut-out image composited against the chosen
background color or a "transparent" diamond pattern. (The background
is not included when the cut-out is saved.)

Note: The
Cut-out view is only updated when you click the Create
Cut-out button on the Tool Palette or use the Preview
Cut-out tool. Fluid Mask does not automatically redo the cut-out
when you change the masks.
View Options
Located below the image display, the following controls let you adjust
the workspace display:

- Show Object Edges:
shows the edges of the objects found in the image. These objects will
be flood-filled when you use the local and global brushes. (The brushes
work the same whether or not the edges are shown.)
- Mask Opacity:
Sets the opacity of the mask overlay. Setting a lower opacity allows you
to see more of the details in your image. Setting a high opacity can help
you spot unmasked areas.
- Workspace Resolution:
Sets the working resolution as a ratio to the image's actual resolution.
For example, if you set the resolution to 1:1, Fluid Mask will show one
pixel for every pixel in the image, but if you set a resolution of 1:2,
Fluid Mask will show one pixel for every four image pixels. Choosing a
lower working resolution can speed up many Fluid Mask operations, at a
small cost to the accuracy of object finding. Unless your cut-out has
very detailed, complex edges, this is often a worthwhile trade-off. When
you save the final cut-out, the finished image always retains the resolution
of the original image, no matter what working resolution you choose.
Note: Changing the workspace resolution will clear any existing
masks.
