On the left example the mask has been inverted. Now when you cut or delete the masked pink area is
protected, everything else is deleted.
You can use masks on top of any drawing or photo.
If you have a mask shape selected when you apply these operations, you'll be asked whether you want
to apply the operation to the mask shape itself, or to the objects shown under the mask using the mask.
This is because you may want to use these operations on the mask shapes themselves and it's not clear
from the context what your intention is.
Duplicate, Clone
This will copy only the visible un-masked parts of the drawing or photo. The Clone option places a copy
exactly on top of the original.
Content Aware photo scaling
To protect part of a photo from being scaled, switch the mask on, draw around the area with the
Freehand tool. Now go into the Content Aware photo scaling tool (Photo tool fly-out bar on the main
toolbar).
See the Content Aware Scaling
feature for more information.
Photo enhance tool
Use a mask to apply brightness, contrast, saturation, temperature and blur/sharpen changes to any part
of a photo. Just draw the mask shape in mask mode, then go into the Photo Tool and start using the
enhance controls on the infobar. See the Photo Tool and Photo Handling
chapters for more information.
Photo clone tool
The clone tool will take a mask shape and convert it into a clone shape, which copies one part of a
photo to another part. See the Clone Tool section of the Photo Tool chapter for details.
