In a previous article (The Scrumpy, February 1990) I discussed the information
and software requirements for transferring graphics between Apple IIGS and
Macintosh computers.  In this installment I've outlined how to use that
information and software to transfer an image from an Apple IIGS to a Macintosh. 
Part III will include information on how to transfer an image from a Macintosh to
an Apple IIGS.

Quick procedure:  On an Apple IIGS, create a graphic, then use SHR.Convert 2.1 to
open a graphic file and save it as a GIF file.  Take the disk to a Macintosh, use
AFE to convert the file to Macintosh format, use a filetype changer to change the
filetype from "06  " to "TEXT", launch Vision Lab, open the graphic file as a GIF
document, select Floyd-Steinberg from the Bitmap menu, and save the file in PICT
or MacPaint format.

Complete procedure: 1.	Apple IIGS: a. Launch your super hi-res paint program
from the Finder. Create a graphic, save it to disk, and return to the Finder. b.
From the Finder, launch Super Hi Res Convert 2.1.  Select the picture type to
convert from the choices in the upper left window; in this case choose "Apple
IIGS specific". Then select the type of graphic you wish to load from the list in
the lower left window.  The possible types are $C0, $C1 (from IIGS paint
programs) and two Print Shop IIGS types.  Next choose "Load & convert..." from
the File menu, insert the disk that contains the file, and open the file.

If you don't know which format the graphic was saved in, just select one format
from the lower left window, then choose "Load & convert..." and try to open the
file.  If the graphic's file name is dimmed (which means it's not selectable),
then the file is not of the type you selected. Cancel the load, select anther
file type, and try to open the file again until the filename is not dimmed (which
means it's selectable), then open the file.  If you still can't select the
graphic you want, then it's probably not a IIGS image.  Change the convert format
to "Apple II family" and try again.

The graphic is now displayed on the screen.  Click the mouse to get back to
SHR.Convert's menu.  Now you must save the graphic in GIF format.  Select GIF
file from the "Select format for saved pictures" window in the upper right.  When
asked to select the size of the saved picture, choose "Same as original" (you
could choose any of the listed sizes, but you can try those later).  Once the
process begins it will take some time, so go get a snack while you're waiting.
When the file is finished, quit from SHR.Convert and return to the Finder.  Drag
the icon of the disk that contains the GIF file to the trashcan to eject it.

2. Macintosh: a. Launch AFE from the Finder.  Insert the ProDOS disk and click
once on the name of the GIF file that you want to transfer.  In the other window,
select the Macintosh disk that you want to copy the file onto.  Next click once
on the Transfer button.  When the transfer is completed, Quit from AFE and return
to the Finder.

b. The graphic image file is now in GIF format on the Macintosh, but has the
wrong filetype designation.  It is listed as type "06  " (that's
zero-six-space-space, which means that it's a ProDOS Binary file), but it must be
in "TEXT" format to be used as a GIF file.  You need to use a filetype changing
program to remedy this situation (see the discussion in Part I).  I'll assume
that you have Filetype Changer.  To use it, launch it from the Finder.  Click
once on the button labeled "ProDOS ('06  ') to Macintosh ('TEXT')".  You will see
a dialog box asking you to select the file that needs to be changed.  Select it
and the filetype change is performed quickly.  Quit from the application and
return to the Finder.

c. From the Finder, launch Vision Lab.  Open the transferred graphic file as a
GIF file.  If the file included color information, and you don't have a color
Macintosh, it will not display but will instead be replaced by the repeating
error message "Color quickdraw is needed to display this image!"  (To quote
Douglas Adams, "Don't panic!").  Select Floyd-Steinberg from the Bitmap menu and
the graphic will be processed and displayed.  From this point, save the file in
PICT or MacPaint format and use in Macintosh programs such as Pagemaker,
MacPaint, SuperPaint, and HyperCard.

In Part III I'll discuss how to transfer graphics from a Macintosh to an Apple
IIGS.  Happy converting!
