RADMOD update

(1 / 1)


RADMOD update:			9/25/89

NEW features:
* reads the Macintosh PICT2 32 bit deep format.  This means you can
	use some of the new rendering programs to produce images which you
	can use in your games.
* using the new features described next, you can take a series of different
  files and combine them into one RAD file with the optimum palette.
  This process requires 2 passes:
   1st pass: send all the pictures you want in the final RAD file
	through RADMOD's palette analyzer (PALA function).
        At the end of this pass, you create a palette file optimized for all 
	the pictures you've just passed through 
	(OUTT to 'plt' format, then COPY).
   2nd pass: send all the pictures through RADMOD again, except this time you
	force them to use the palette you just created (COPY function, then
	answer the palette question by indicating you want to use that
	palette you just created).
* PALA: analyze palettes.  This allows you to pass several files through 
  RADMOD to get their palette/color usage analyzed.  When you've analyzed
  all your files, you can create and save the best palette for all these files
  by setting the output file type to "plt" (see next new feature) and then
  selecting the "COPY" menu option.
* outputs a RAD type palette file.  Select OUTT menu option (Set Output File 
  Type) and enter "plt".  Then select COPY menu option.  It will output a RAD
  type 256 color palette.
* allows you to force a picture to use a specified palette.  This function is
  available when you're reducing down from 32,24,or 16 bits.  You get a
  set of options when you're converting down from these bigbit files:
   > create best palette for this picture?
   > get palette from a file and use it?   
   > use current output palette?
  If you select option 2, you'll be asked for the file from which to get the
  palette.  Theoretically, you can enter the name of any file containing a 
  palette and it will go in and get the palette.  The only file type tested so
  far is the new "plt" (raw palette file) format. (Rad files for sure don't
  work yet).
  If you've already done one picture and selected option 2, then the next
  picture you do you can answer with option 3. This is much quicker then #2.
  You will be asked whether or not you want to dither to the final palette.
* some rather obscure options have been added:
  > when dithering, you can now (optionally) specify transparent color(s) 
    which, of course, won't be dithered.  You specify the index of the main
    transparent color, and you can also specify another range of colors which
    are to be remapped to the main transparent color.  If you're good, you can 
    use this method to cookie cutter your object.  What you do is place the
    extra range of colors to be mapped to the one final transparent color after
    the final actually used colors in the palette.
  > when creating the ultimate palette, you can (optionally) specify the minimum
    # of pixels (as a number or as a percentage of the total # of pixels)
    using a color in the palette for it to exist.  This one can really screw up
    your palette if you're not careful.
* scale now works on the original 15 bit image before it reduces to 8 bits, so
  you get higher quality scaling.
* the page/cel mode is now specified explicitly in the cel choice selection.

For your protection, I have placed a copy of the previous version of RADMOD
into [theurer.pps]radmod911.exe, in case you have problems with the new version.
