[comp.sys.amiga.graphics] several questions on dpaint, and selective fading

wayne-s@tut.cis.ohio-state.edu (derbaer) (04/23/91)

As a generla background, the machine that i am working with is an Amiga 1000
with beefed up ram ( 1.5 meg ) and a 40 meg hard drive. The software that i 
am currently working with ( relevant to the question ) is workbench 1.3 and 
DeluxePaint III. 

I would like to be able to take a dpaint file, and selective fade in and out 
any and/or all of the colors used to create the image from some specified 
initial point to the images final color scheme. 

eg.  I have three squares colored red, blue, and green on a black background.
I want to be able to start with the initial picture, and then fade the red 
square, then the blue, then the green, to the background color in succession. 

Now, what i _don't_ know is how unreasonable i am being in this line of 
questioning.  I should think this feat to not be very hard, but then i could 
be wrong... :D 

So are there any PD, shareware, commercial programs that do what i speak of? 
I'll settle on a binary, but would be oh so pleased to glom onto code as well.


I thank you all for the time and consideration, and i'll post a summary of 
what i recieve in responses.

As far as I know it is a very easy feat; meant in terms of what the computer
must do, and can do. F.x, I could do things like that by reading the picture
in from AMIGABASIC and then alter the palette(It is so easy, because it is
not HAM). Practically, though, a program suitable for this would be written
in a compiled language(Modula-2(my choice) or C.

I don't know of any, but there should at least be(it is not an all-silly
purpose). A problem concerning the nature of what should be done, though is
this: Assuming you only want to do the described effect, a program for this
sole purpose could be written and used. But the best would be a program
more general in concept, to do various effects. And this is the problem:
Devicing an interface, with which one could describe these effects(e.g.
tell the computer what to do) seems hard to me; it would maybe be easier
to program the solution.

just my 17.623 $ of worth(well its abit long, isnt it?)

I belive that Deluxed Video has a "fade" command as does "The Director"..
sorry I don't know of any PD code that'll do the same..

(You say you want to selectively "fade" in different colors in an anim . . .)

YES!  I have done this many times: ANIMagic is the program that you need!
It will work with DPaint anim files -- just make the anim in DPaint with
your colors at their final colors.  Then in Animagic, choose the colors,
one at a time, and change the value in the first frame to, say, white.
Then press the "pallette range" button (or whatever it's called) to get
the color to change from the white value to the final color value.  It
will work over whatever range you specify.  Each color can fade indepen-
dently, etc.  It's a simple little feature that can really spice up your
animations.  Highly recommended!  Plus, you get all those groovy customiz-
able special effects.

Having tried DeluxeVideo III and The Director, my advice is: forget those
two programs and buy ANIMagic instead.  Unless you need synchronized sound,
ANIMagic will give you much better results than either one of those over-
rated programs.  The Director's "fade" command, in particular, look pretty
hokey, and if you try a wipe in DeluxeVideoIII with a hi-res overscan 
screen you can't believe EA expects people to use the program.  Uck!
