You can specify the
following options in the GOPTIONS statement to configure Web presentations
that are generated with the GIFANIM device.
ITERATION=
iteration-count
specifies the number
of times to repeat the animation loop. The default value of 0 continues
the animation indefinitely (until the Web user selects Stop or displays
another Web page in the Web browser). Specifying a number greater
than 0 repeats the animated sequence for the specified number of iterations,
and then continuously displays the last image in the sequence, unless
the DISPOSAL= graphics option specifies otherwise.
specifies whether the
graphics output should replace the contents of an existing file or
be appended to it. In this case, the value of REPLACE specifies that
the device is to write a GIF header. Use the GSFMODE= option to specify
when to write the GIF header. Specify REPLACE before you generate
the first GIF image, and then specify APPEND in a second statement
before you generate the rest of the images.
specifies the amount
of time that each image is displayed, in hundredths of a second. For
example, a value of 1 specifies a delay of 0.01 seconds. The default
value is 0.
DISPOSAL=NONE | BACKGROUND | PREVIOUS | UNSPECIFIED
specifies how the image
sequence is to be displayed.
superimposes the images
in the sequence, without removing any of them from the screen. This
is the default value.
restores the background
color before displaying the next image.
replaces the current
image with the previous image before displaying the next image.
takes no further action
before displaying the next image.
TRANSPARENCY | NOTRANSPARENCY
specifies whether the
background of the image should be replaced by the background color
of the Web browser.
INTERLACED | NONINTERLACED
specifies whether interlacing
is to be used as the images are displayed.
