[comp.sys.apple2] Digitized Pics

gentrys@infonode.ingr.com (Scott Gentry) (02/13/91)

To convert a 320 mode (Allison currently only does 320 mode - future versions
will do 640 mode) picture to 640 mode, you can obtain (purchase) any of the
following programs:

SuperConvert (Best color translations when using raw images)
The Graphic Exchange (Ok, but not great color translations)
Second Chance (Great monochrome translations)

or...

If you have a paint program such as Platinum Paint, you can do direct to system
palette translation (can lose detail when remapping colors).  Additionally, you
can save the Allison picture as an Apple Preferred file and have AWGS attempt
the translation for you (can be good, can be bad).

If you have Paintworks Gold, you can perform the following steps:

1. Load graphic.
2. Select marquee tool.
3. Press spacebar.
4. Select entire screen or portion you wish to translate.
5. Press spacebar.
6. Select cut from the Edit menu.
7. Select change to 640 from the Apple menu.
8. Select paste adj. colors from the Edit menu.
9. Save the graphic as an Apple Preferred file.

NOTE: This method produces identical results to the Platinum Paint method. If
you wish to use pictures converted with this method in AWGS, you will need to
first load the PWG palette picture in AWGS's graphics module.  The picture
should import just fine in other AWGS modules.

Hope this helps!

In a previous post, someone said this... "    In a couple of words:  you can't.
AWGS must use 640-mode graphics, and
320-mode pictures (which is what I assume the Allison pictures are in) don't
look very nice at all when converted to 640-mode.  There aren't nearly enough
colours, and AWGS doesn't do multiple palettes.

Ummm.... Brian, the pictures from Allison can be used.  They must be converted
first, though.  The methods I outlined and the programs I mentioned do jobs
ranging from outstanding to ok...  Additionally, pictures made with Allison
(NOT Allison/3200) use a single palette.

Hope this clears up some confusion.

    The original poster wanted to know if it was possible to import Allison
pics into AWGS, complete with the original palette.  Yes, you can load in the
bitmap, but it will be practically impossible to match the 320-mode colours in
dithered 640-mode.  It would be nice if AWGS kept the original palette for
each graphic in memory, and display the closest match on screen.  Then when
you go to print it out, it would use the original colours.

In a previous post, Brian Tao said "  Yes, you can load in the

dithered 640-mode."

Yup, it's impossible to get an exact match but with some fiddlin' and faddlin'
you can get pretty darn close.  :-)
