NAME
zoom - an icon editor for
mgr
SYNOPSIS
zoom
<icon file> ...
DESCRIPTION
zoom
is a mouse driven icon editter for
mgr.
Zoom
divides the window into three regions, a banner line at the top containing
four status fields,
a message line at the bottom,
and the remainder of the window for an enlarged, or
zoomed
representation of
<icon>
being editted.
If the first file given on the command line is not an icon,
zoom prompts for its width and height.
The current state of zoom is indicated by the four status fields in the
banner line.
- *
-
The first, or
raster function
field displays the current raster-op function to be applied to the next
edit operation. This function may be changed with the pop-up menu,
activated by pressing the middle mouse button while the mouse track is in the
raster function
field.
Normally the choices are
set, clear, toggle
and
grid.
The first three are raster-op functions; the
grid
option toggles the bitmap alignment grid.
If the
put
command is pending (see below), the raster-op choices become
copy, paint mask,
and
exclusive-or.
- *
-
The second, or
edit
field displays one of the six possible edit functions:
Yank, Put, Shrink, Grow, Fix,
and
Undo.
Fix and Undo are performed when selected.
Fix
changes the window size
to give square pixels.
Undo
un-does the previous edit operation.
If any of the other functions is selected, it becomes the pending function,
and is highlighted.
When a function is pending, the next sweep operation performs that function
on the group of pixels enclosed by the sweeping rectangle (the
selected
pixels).
-
- Yank
-
copies the
selected
pixels into the yank buffer.
- Put
-
combines the yank buffer with the
selected
pixels in a manner determined
by the current
raster function
field.
- Shrink
-
makes the icon smaller by scaling the selected pixels to fill the entire
window.
- Grow
-
makes the icon bigger by scaling the entire icon to fit into the
selected pixel region.
- *
-
The Third or
size
field displays the current
width
and
height
of the icon, in pixels.
The size of the icon may be changed by selecting the pop-up menu
when the mouse track is in the
size
field
and responding to the prompt.
While in the prompt window, the menu permits the selection
of several standard icon sizes.
- *
-
The fourth, and final field is the
file
field.
The
file
field displays the current file name of the icon.
The filing options
Save, Get, Yank,
and
Quit
are, as usual, accessed by a pop-up menu when the mouse track
is in the
file
field.
The
file
options prompt for a file name.
A list of all of the files specified on the command line
is available via the pop-up menu within the prompt window.
-
- Save
-
saves the icon by the specified name.
- Get
-
edits a new icon , tossing the current icon into the bit-bucket.
- Yank
-
copies the specified icon into the
yank
buffer for use with the
put
command.
- Quit
-
quits
Zoom. Quit does
NOT
save the icon. A save must be explicitly issued first.
Zoom may also be terminated by typing
"Q\r" to the window, or hitting your favorite interrupt key.
For those who are not particularly font of rodents, all of the
zoom
commands may be accessed via 1 or 2 letter keyboard commands
(followed by a \r), some of which
are:
R Repaint window
x toggle alignment grid
w FIX window aspect ratio
u UNDO
s1 select SET mode
s2 select CLEAR mode
s3 select TOGGLE mode
f SAVE file
g GET a new file
y YANK a file
Q QUIT
F1 select YANK function
F2 select PUT function
F3 SHRINK icon
F4 GROW icon
P0 set COPY mode
P1 set PAINT mode
P2 set MASK mode
P3 set XOR mode
Okay, now to edit the icon.
- *
-
Pressing the middle button and moving it either sets or clears the pixels
it passes over. If the first pixel it touches is clear, the pixels will
be set; if it is set, all touched pixels will be cleared.
- *
-
Holding, moving, then releasing the right mouse button sweeps out
a rectangular region of
selected pixels.
If no function is currently highlighted in the
edit
field,
the current raster-op function is performed on
the selected pixels.
Otherwise, the highlighted function is performed.
BUGS
- *
-
Zoom works best on small icons, running on the local machine.
- *
-
You can't view the actual size of the icon being editted.
- *
-
Icon coordinates must be typed in exactly in the form of
x
,
y
with no spaces or tabs.
