A dashed border outlines the
selected area in a photograph
Selection borders
The selected pixels in an image are referred to collectively as a selection. When you make a selection,
Canvas surrounds the selected pixels with a moving dashed border. You can hide and display the
border without affecting the selection.
To hide the border:
Choose Image | Select | Hide Edges.
To display the selection border:
Choose Image | Select | Show Edges.
Deselecting an image selection
When you use a selection tool in normal mode, making a new selection replaces any existing selection
in an image.
To deselect pixels without making a new selection:
Choose Image | Select | None. You can also press Esc to deselect a selection. If a selection is
floating, pressing Esc once defloats the selection; pressing Esc again deselects all pixels.
Selecting all pixels in an image
You can apply painting tools and filters to an entire image without first making a selection. But you
can also select all the pixels in an image when you want to work with them as a selection.
