Intelligent Scissors
Click a series of points in the image. As you click, the points are connected based
on color differences. Click on the first point to close the area. Convert it to a regular
selection by clicking inside it.
Using the Quick Mask
The quick mask is a way of selecting parts of an image using the paint tools. A good
way to use it is to make a rough selection using the intelligent scissors or the lasso
(freehand selection tool). Then activate the quick mask by pressing the small icon with
the dashed box in the lower left corner.
The quick mask displays the selection using an overlay of red. Areas shaded with red
are not selected. Areas appearing as they did before the mask was activated are selected.
To modify the selection, use the paint tools. Painting with white selects the painted
pixels. Painting with black deselects pixels. Shades of gray (colors are treated as shades
of gray) are a partial selection. Partial selection allows smooth transitions between se-
lected and unselected areas.
To use a different color for displaying the quick mask, right-click the quick mask button
then select Configure Color and Opacity from the menu. Click the colored box in the
dialog that opens to select a new color.
After using the paint tools to adjust the selection as desired, convert from the quick
mask view back to the normal selection view by clicking the icon in the lower left corner
of the image window (currently displaying a red box). The selection is again displayed
with the marching ants.
18.5.3 Applying and Removing Color
Most image editing involves applying or removing color. By selecting a part of the
image, limit where color can be applied or removed. When you select a tool and move
the cursor onto an image, the cursor's appearance changes to reflect the chosen tool.
With many tools, an icon of the current tool is shown along with the arrow. For paint
tools, an outline of the current brush is shown, allowing you to see exactly where you
will be painting in the image and how large an area will be painted.
