In two previous articles (The Scrumpy, February 1990, March 1990) I discussed the
how to transfer graphics between Apple II series and Macintosh computers.  In
this third installment I've outlined how to transfer images from a Macintosh to
an Apple IIGS.

There are three methods you can use for this transfer:  use The Graphic Exchange,
use Super Hires Convert 2.1, or use GIF files.

The Graphic Exchange, by Roger Wagner Publishing, Inc. (1050 Pioneer Way, Suite
P, El Cajon, CA 92020) can read Macintosh disks directly and makes a clean &
simple conversion of MacPaint files to Apple II format.  Although images can be
transferred to various Apple II formats, MacPaint images look best when converted
to IIGS-specific screen modes. Consult the program's manual for directions.

Super Hires Convert 2.1 also allows conversion of MacPaint files to Apple II
format, however, it can only read ProDOS disks.  To use it, save the MacPaint
image (while on the Macintosh), launch Apple File Exchange, insert a ProDOS disk
and transfer the graphic file onto the ProDOS disk.  On the Apple IIGS, launch
SHR.Convert from the Finder and use that ProDOS disk as the source for the image.
 Choose "Macintosh" as the picture type to convert, then load & convert the
image.  When finished, save it as a "$C0,2 Apple Preferred" graphic.

The use of GIF files is a little more involved, but once you master the process
you will be able to transfer files to and from virtually any computer system that
uses them.

Quick procedure:  On a Macintosh, create a graphic image and save it in MacPaint
format (or, if your paint program allows it, save it in GIF format).  Launch
Vision Lab, open the file as a MacPaint image, save it as a GIF file.  Use a
filetype converter to change its filetype to "06  ".  Launch AFE and transfer the
file onto a ProDOS disk.  On an Apple IIGS, launch SHR.Convert 2.1, open the GIF
file, then save it as a $C0 file for use with your paint programs or HyperStudio.

1. Macintosh: a. Start up the computer and launch your paint program. Create a
graphic, save it to disk as a MacPaint file, and return to the Finder. b. From
the Finder, launch Vision Lab.  Open the file as a MacPaint file.  Save the image
as a GIF file.  Return to the Finder. c. The file is saved as a GIF file with a
filetype of "GIFf" but it needs to be filetype "06  " to be used on the Apple
IIGS.  To do this, launch Filetype Changer (or any other filetype changing
utility) and select Macintosh ('GIFf') to ProDOS ('06  ')".  Once completed,
return to the Finder. d. Launch AFE.  Select the location of the GIF file, then
insert the ProDOS disk that will receive the file.  Click on the file, then click
on the Transfer button.  When completed, return to the Finder.

1. Apple IIGS: a. Launch Super Hi Res Convert 2.1 from the Finder.  Select the
picture type to convert from the choices in the upper left window; in this case
choose "Computer independent". Then select "GIF" from the list in the lower left
window. Next choose "Load & convert..." from the File menu and open the desired
file.  If the image is larger than your computer's display, scroll the image to
the position you want it, then click the mouse to get back to SHR.Convert's menu.

Now you must save the graphic in an Apple IIGS format. Select "$C0, 2 Apple
Preferred" from the "Select format for saved pictures" in the upper right window.
 When asked to select the size of the saved picture, choose "One screen wide, one
screen high" (you could choose any of the listed sizes, but you can try those
later).  When the file is completely saved, quit from SHR.Convert and return to
the Finder.  The image can now be used by a IIGS-specific paint program or
brought into HyperStudio.

This concludes the three-part discussion of transferring graphics between Apples
and Apples.  Contact me at the monthly OACC meetings if you have any questions or
comments.
