Drag from the starting point to the ending point. Hold down the Shift key to constrain
the tool to multiples of 45°.

To create a protractor from an existing measuring line, Alt-drag (Windows) or Option-
drag (Mac OS) at an angle from one end of the measuring line, or double-click the line and
drag. Hold down the Shift key to constrain the tool to multiples of 45°.
To edit a measuring line or protractor:
1
Select the measure tool
.
2
Do one of the following:
•
To resize the line, drag one end of an existing measuring line.
•
To move the line, place the pointer on the line away from either endpoint, and drag
the line.
•
To remove the line, place the pointer on the line away from either endpoint, and drag
the line out of the image.
Note:
You can drag out a measure line on an image feature that should be horizontal
or vertical, then choose Image > Rotate Canvas > Arbitrary and the correct angle of
rotation required to straighten the image will already be entered into the Rotate Canvas
dialog box.
Using guides and the grid
Guides appear as lines that float over the entire image and do not print. You can move,
remove, or lock a guide to avoid accidentally moving it.
In Photoshop, a grid appears by default as nonprinting lines but can also be displayed as
dots. The grid is useful for laying out elements symmetrically.
Guides and grids behave in similar ways:
•
Selections, selection borders, and tools snap to a guide or the grid when dragged
within 8 screen (not image) pixels. Guides also snap to the grid when moved. You can
turn this feature on and off.
•
Guide spacing, along with guide and grid visibility and snapping, is specific to an image.
•
Grid spacing, along with guide and grid color and style, is the same for all images.
To show or hide a grid or guides:
Do one of the following:
•
(Photoshop) Choose View > Show > Grid.
•
Choose View > Show > Guides.
•
Choose View > Extras. This command also shows or hides: (Photoshop) selection edges,
target path, slices, and notes, or (ImageReady) selection edges, slices, image maps, text
bounds, text baseline, and text selection. (See
“Working with Extras” on page 47
.)
