General Information
\} \wr
This capability is designed to be used in the multi-sequence
processor. The idea is that often, you'll want to create a transition
of some kind between two images.
The simplest type of transistion is a \ts i cut\ts n , where the images being
displayed suddenly and completely change from one to another. Cuts are easy -
you just "do" them.
\anim "clips/cut.anim" c 3
\flushimage
\{ \ce
\anlink " \tc DarkBlue Show Cut " 3 P 3 100\}
Another kind of transition, which you can often do with a moderately
sophisticated VCR, is a \ts i fade\ts n . Fades are transitions where one
image fades out as another fades in. This is much more sophisticated (to
perform) than a cut, because it involves processing the two images against
each other.
\anim "clips/fade.anim" c 2
\flushimage
\{ \ce
\anlink " \tc DarkBlue Show Fade " 2 P 3 100\}
Other type of transitions include geometric, or pattern transitions.
These allow a second image to "show through" a pattern of some type;
the pattern changes shape in such a way during the operation of the
transition so that one image dissapears and another appears. An
ellipse that grows larger than the display is an example of this type
of transition.
\anim "clips/gak.anim" c 1
\flushimage
\{ \ce
\anlink " \tc DarkBlue Show Pattern " 1 P 3 100\}
Finally, we have the class of transitions call \ts i wipes\ts n . A wipe is a
transition where one image actually moves onto the display, for instance,
from the left edge, covering the image that was there previously.
\anim "clips/wipe.anim" c 0
\flushimage
\{ \ce
\anlink " \tc DarkBlue Show Wipe " 0 P 3 100\}
Imagemaster R/t can produce many types of each of these classes of
transitions, and often will do so with finer detail than other hardware and
software transition generators in common use in the Amiga community.
It is really quite easy to use the transition generator: First, you
need two images. Load one as primary, and then load one, or assign one if one
is already loaded, as the secondary. Next, in the sequence control panel,
select Set Scripts and place the following information in the
\ts b Pre-Render \ts n script box:
\{ \tc DarkBlue \nw
rxpi:wipe.rexx\}
Once you have done this, you can use the "Primary" option in the Run
Scripts panel of the sequencer to generate transitions.
When you press the Primary button, the transition generator will be
invoked; it "knows" you have not (yet) selected the particular
transition you want to use, so it will pause and ask you which one
you want; select from the list presented to you and off it goes.
If you'd like to test the transitions, then turn on the filmstrip and
make sure that TEST is selected in the Run Scripts panel of the
Sequencer... that way, the generated transitions are placed in the
filmstrip only, not rendered or saved as 24-bits.
Here is a list of some of the currently available transitions:
\{ \nw \lm 40
\{ \ts b BLToTR \} \{ \tc DarkBlue ---- \} \{ \ts i Bottom Left (to) Top Right\}
\{ \ts b BRToTL \} \{ \tc DarkBlue ---- \} \{ \ts i Bottom Right (to) Top Left\}
\{ \ts b TLToBR \} \{ \tc DarkBlue ---- \} \{ \ts i Top Left (to) Bottom Right\}
\{ \ts b TRToBL \} \{ \tc DarkBlue ---- \} \{ \ts i Top Right (to) Bottom Left\}
\{ \ts b LToR \} \{ \tc DarkBlue ------ \} \{ \ts i Left (to) Right\}
\{ \ts b RToL \} \{ \tc DarkBlue ------ \} \{ \ts i Right (to) Left\}
\{ \ts b BToT \} \{ \tc DarkBlue ------ \} \{ \ts i Bottom (to) Top\}
\{ \ts b TToB \} \{ \tc DarkBlue ------ \} \{ \ts i Top (to) Bottom\}
\{ \ts b Ellipse \} \{ \tc DarkBlue --- \} \{ \ts i Elliptical Pattern(s)\}
\{ \ts b Rect \} \{ \tc DarkBlue ------ \} \{ \ts i Rectangular Pattern(s)\}
\{ \ts b VBlind \} \{ \tc DarkBlue ---- \} \{ \ts i Vertical Blind pattern(s)\}
\{ \ts b HBlind \} \{ \tc DarkBlue ---- \} \{ \ts i Horizontal Blind pattern(s)\}
\{ \ts b Fade \} \{ \tc DarkBlue ------ \} \{ \ts i Fade from (to)\}\}
The pattern fills (Ellipse and Rectangle) can be "tiled", where there
can be any number of the chosen pattern across, and any number of
them down, the image during the course of the transition.
In addition, you'll have the opportunity to select with or without
fading for any pattern fill; in fact, there are a number of options
you can select such as "inverse time", "inverse pattern", and fading
as mentioned.
As with many of Imagemaster R/t's powerful tools, playing with this will
reveal the flexibility available; talking about it won't, at least not very
well. So play!
Note that we may be supplying more types of transitions with future
upgrades; the transition generator is "open-ended"; unlike hardware
solutions, new transitions can be added just a few at a time, or even
one at a time!
If you are a technically inclined type, new transitions can be added
by creating new .rxwp files; you can do this also. If you're curious,
call tech support and enquire into writing your own.
