This is a very brief manual for Gif•gIf•giF. It can be found online at
http://www.peda.com/ggg/man.html.
We begin with an overview of the single control window. All of the elements
of the control window are described, proceeding from top to bottom.
File Name
The control window's name is the name of a saved animation, or
"Untitled" if the animation has not been saved.
Registered User's Name
The user's name is displayed next. GIF† animations produced using
Gif•gIf•giF include a GIF comment "Made by <user's name>, using
Gif.gIf.giF v1.24.". GIF comments are not shown during playback,
but can be seen by GIF editing programs.
General Controls
Start
Press the Start button to begin recording a sequence of
frames. After the button is pressed, a 3-second countdown is
displayed, after which recording begins.
Alternatively, recording may be started by pressing
control-option-command.
Grab
The Grab button is used to capture single frames. Pressing
the button causes the current area to be added to the
current animation.
Single frames may also be captured by pressing
shift-option-command.
Stop
Press the stop button to halt a recording session that has
been started using the Start button.
Alternatively, recording may be stopped by pressing
control-option-command.
0 Frames (0 bytes)
Displays the size of the current animation, in frames and
bytes. Large animations (in bytes) will take a long time to
download; a 14.4k modem can download 60-80K per minute when
there are minimal network delays. After saving, the
animation will be slightly larger, as a file terminator must
be added after the last frame.
Capture Area
The desired capture area should be selected before recording an
animation. Once frames are recorded, the capture area cannot be
changed.
Size: 400x300
Displays the current size of the capture area; in this case
the capture area is 400 pixels wide and 300 pixels high.
With unregistered copies the sizes before and after
inserting the "Unregistered Copy" banner are displayed.
Top Left: 0,0
Displays the coordinates of the top left corner of the
capture area; in this case the capture area includes the top
left corner of the display. Such information is useful if
one can fine-tune the program being captured to stay within
the capture area.
Show Area
When checked, causes the current capture area to be outlined
with a slowly moving frame. The outline is just outside the
capture area, so the moving frame will not be placed in the
animation.
Select Area
Press to select a new capture area using the mouse.
To select a window easily, hold down the shift key to change to
"Select Window". Then press the button and place the cursor
over the window you want to select - some marching ants
should outline the window area - and then click to
select it as the capture area. The select area process can be
aborted by pressing escape.
If you are having difficulty selecting the window you want,
try pressing the space bar during selection and ensure that all
finder windows are in the far background.
Refresh screen
Press to refresh the screen contents; all programs will
redraw their windows.
Capture Options
The capture options should be selected before recording an
animation. Many of the controls are locked after recording has
started.
Maximum Frame Rate: 3 fps
The maximum frame rate controls the rate at which frames are
captured. It defaults to 3 fps, or 3 frames per second. At 3
fps, 1/3 of a second elapses between captures; on slower
machines the actual frame rate may be significantly below
the selected frame rate. The slowest selectable frame rate
is 5 spf - 5 seconds per frame. Higher frame rates generate
smoother, larger animations. Frames are output only when
successive captures differ.
Interframe Transparency
When selected, transparency is used to produce compact
animations: any areas that do not change between successive
frames will be recorded as transparent areas in place of the
actual image.
Record Timing Info
When selected, timing information is placed in the
animation. If 1/3 of a second elapsed (during the recording)
between two frames, the two frames will be displayed 1/3 of
a second apart. When timing information is not recorded, the
subsequent animation is played back as quickly as possible.
When grabbing single frames (with the Grab button) the
maximum frame determines the timing information. A frame
rate of 5 fps results in 1/5 of a second wait between frames
on playback.
Loop
When selected, the produced animation will loop infinitely.
When not selected, the animation will play once and stop on
the last frame.
Fake Screen
When selected, a fake screen is placed over the actual
capture area. The fake screen includes rounded borders, and
the process and help menus. A fake screen is not painted in
if the top left corner of the capture area is not 0,0.
Overlay Border
When selected, a thin black outline is placed around the
animation. The border is drawn over the pixels on the edge
of the animation.
Overlay Cursor
When selected, a cursor is added to each frame of the
recording. The option is normally not used, as the cursor
will be captured automatically during recording. Some
graphics cards overlay the cursor while updating the screen;
with such cards this option should be used.
Explorer 2.0 Compatible
When selected, recorded animations will be viewable under
the Macintosh version of Microsoft Internet Explorer 2.0.
They will also take up a little more disk space. This setting
is not required for compatibility with Internet Explorer 3.0
(currently available on Windows only) since it follows the GIF
specification better than version 2.0 does.
Recording size: 100%
Recording size can be:
100%, which is the size of the original captures;
44%, which is 2/3 the width, 2/3 the height of the original; or
25%, which is 1/2 the width, 1/2 the height of the original.
With smaller recording sizes, it is possible to capture large areas
of the screen as a smaller animation which can be viewed within the
browser window without scrolling. However, scaling might cause
loss of details, in which case changing the size of the original and
recording at 100% is recommended.
When a recording size other than 100% is selected, the Capture Area Size
shows both the original capture area size and the size of the animation.
You are now ready to record animations.
* When recording in 256 colours, ensure the subject (captured program)
is foremost when recording starts. The colour palette is captured at
this time and is used for all frames; ignoring this rule may cause colour
inconsistencies. Gif•gIf•giF does not work well with programs that change
their palette as they execute. Additionally, the fake screen's process
menu is captured on the first frame.
* When working on a Macintosh with multiple monitors, recordings can
only be made on the main monitor, which is the one containing the menu bar.
* Unregistered copies of Gif•gIf•giF will produce animations
with a banner proclaiming "Unregistered Copy...Unregistered Copy...".
Registered copies of Gif•gIf•giF do not insert a banner.
* Some GIF animation editors have difficulty interpreting transparent
frames. Editing may be made possible by disabling the automatic interframe
transparency before recording starts.
