To erase with the Background Eraser:
1. Select Background Eraser from the Tools toolbar's Eraser
Tools flyout.
2. (Optional) Change properties on the Context toolbar as described
above.
3. Drag with the tool on the active layer to erase pixels similar to a
sampled reference color directly under the brush tip.
• With "Contiguous" limits (the default), the tool erases only
within-tolerance pixels adjacent to each other and within the
brushes width; this tends to restrict erasure to one side of an edge
or line. When you set "Discontiguous" limits, all matching pixels
are erased under the brush even if they are non-adjacent (great for
removing uniform background like sky). The "Edge Detected"
setting can improve erasure along one side of a contrasting edge
or line.
Contiguous Discontiguous
• With "Continual" sampling (the default), the reference color is
repeatedly updated as you move the cursor. Sampling "Once"
means erasure is based on the color under the crosshair when you
first click. Use the "Background Swatch" setting to use the
current background color (Color tab) as the reference.
