The tools in the toolbox allow you to select, paint, edit, and
view images.
Listed below are descriptions of the tools in the toolbox.
The marquee tool is used to make rectangular and elliptical
selections
within the image.
The lasso tool is essentially the same as the marquee toll,
except that the lasso tool enables the user to define the selection
freehand. This tool is especially helpful in isolating irregularly-shaped
objects surrounded by other objects.
The magic wand tool makes selections based on the color
similarities of adjacent pixels. This tool is useful in selecting
part of an image without tracing the outline with the lasso tool.
The move tool is used to move selections by dragging the
mouse.
The hand tool is used to scroll through an image that does
not fit in the active window.
The zoom tool is used to magnify an image (not to change
its size). This tool can also be used in conjunction with the
Option key on the keyboard to zoom out.
The cropping tool discards the remainder of the image outside
of the region selected by the tool.
The paint bucket tool fills in areas that are adjacent
to the point you click with the current foreground color.
The gradient fill tool creates a gradual transition from
the foreground to the background color.
The line tool paints straight line segments. Properties of the lines,
including width and arrowheads, can be changed by double-clicking
on the line tool in the toolbox.
The eyedropper tool is used to sample and match colors
in an image.
The eraser tool erases pixels and changes them to the same
color as the background color (usually white).
The pencil tool can be used to color individual pixels.
The airbrush tool is used to apply a diffused spray of
the foreground color on the image.
The paintbrush tool paints soft-edged strokes of the foreground
color.
The rubber stamp tool samples a part of an image and can
place an exact copy of that sample elsewhere.
The smudge tool simulates the effect of dragging a finger
through wet paint.
The blur/sharpen tools blur or sharpen parts of an image.
The dodge/burn/sponge tools can lighten, darken, or change
the saturation of part of an image.
