Editing And Retouching; Monitoring Operations; Correcting Mistakes - Adobe PHOTOSHOP 5.0 User Manual

Chapter 8: Editing and Retouching
A
dobe Photoshop makes it easy to edit and
retouch your images. For example, you
can move and copy selections within and
between images and also between programs. A
variety of editing tools let you modify your images
and apply special effects.
Keep in mind that pixels beyond the borders of the
visible canvas cannot be edited or retouched.
However, you can use the move tool or selection
arrows to move these pixels back onto the visible
canvas, you can modify or reposition them using
any of the Transform commands, or you can
increase the canvas size to incorporate them.

Monitoring operations

You can't continue working while a progress bar is
displayed, indicating an operation is in process.
But you can usually interrupt the process or have
the program beep when it's done.
To interrupt operations:
Hold down Esc until the operation in progress has
stopped or press Command+(.) (Mac OS only).
To set the beep:
Choose File > Preferences > General.

Select Beep When Done, and click OK.

Correcting mistakes

Most operations can be undone if you make a
mistake. Alternatively, you can restore all or part of
an image to its last saved version. But available
memory may limit your ability to use these
options.
For information on how to restore your image to
how it looked during any point in the current work
session, see "Reverting to any state of the image"
on page 168.
To undo the last performed operation only:
Choose Edit > Undo.
If an operation can't be undone, the command is
dimmed and changes to Can't Undo.
To free memory used by the Undo command, the
History palette, the Clipboard, or the Pattern buffer:
Choose Edit > Purge, and choose the item type or
buffer you want to clear. If already empty, the item
type or buffer is dimmed.
Important: The Purge command permanently
clears from memory the operation stored by the
command or buffer, and cannot be undone. For
example, choosing Edit > Purge > Histories deletes
all history states from the History palette. Use the
Purge command when information held in memory
is so large, Photoshop cannot perform the next
operation.
