[comp.sys.apple] Super-High Res Graphics

aehl@csd4.milw.wisc.edu (Donald J Aehl) (01/20/88)

I am having difficulty loading a Medium Super-High Resolution Picture (320x200)
into the graphics programs which I own. I think the problem has to do with 
linearization of the bank $E1 super high-res buffer but I can't seem to effect
any change by altering this setting.

Specifically, I am ploting a graphic on the Super high-res screen of my IIgs 
using an ampersand utility that was published in Nibble magazine a few months
back.  I have checked and this program does initialize linearization of the
buffer and it seems to use the standard Apple IIgs pallette and SCBs.  Infact,
it claims that the final picture can be saved and directly loaded into either
Paintworks Plus or Deluxe Paint II.

Well, I own both of these programs and the pictures do not load properly into
either of these programs. When they are finally loaded the Pallete is messed
up and the image is split into four smaller (but not identical) images of the
original graphic.  It seems to be using every fourth nibble of the super high-
res buffer for each shrunken image.

Has anyone else encountered this difficulty?  Everytime I manually load the
graphic into memory it is displayed correctly, and every time I try to load
it into one of these programs it loads incorrectly. 

I saved the picture using the following commands:

(while in the monitor)
C029: C1 <return>
00/1000<E1/2000.E1/9FFFM <return>    (monitor move command)
CREATE PICTURE,A$1000,E$8FFF,T$C1 <return>
BSAVE PICTURE,A$1000,E$8FFF,T$C1 <return>

This does seem to sucessfully save the graphic because when I enter the
following commands to load the image it is displayed normally:

(while in the monitor)
BLOAD PICTURE,A$1000,L$7FFF,T$C1 <return>
E1/2000<00/1000.00/A000M <return>
C029: C1 <return>

I repeat, this procedure sucessfully loads and save the image to and from
memory but the file will not sucessfully load into either Paintworks Plus
or Deluxe Paint II.  The above procedure doesnot work when I save it as a
TBIN file either.  Cann anyone suggest a solution to my problem?

Thanks in advance for any help
