IFF2PCS 1.1

IFF2PCS (IFF-to-pieces) is an interactive puzzle program. In
IFF2PCS, the user's goal is to put a picture back together
from square pieces. The picture can be created from any IFF
picture, and can have up to 16 colors. A sample picture is
included.
IFF2PCS can be started one of three ways:
* From the CLI, by typing
1> iff2pcs IFF-FILE (where IFF-FILE is the name
of an IFF picture file)
* From the Workbench, by double-clicking on the icon of an
IFF picture file, provided the "default tool" is set to
IFF2PCS. (The icon for the sample IFF picture provided
with the program is configured this way.)
* From the Workbench, by
first clicking once on the IFF2PCS icon,
then double-clicking on the icon of any IFF picture
file, while holding down the SHIFT key.
This last method (a standard way to specify arguments to
Workbench programs) allows you to start IFF2PCS up with
any IFF picture, even if its default tool is not set to
IFF2PCS.
Once IFF2PCS starts up, it provides you with a choice of
three difficulty levels. You can start the game by clicking
on the appropriate choice:
* REAL EASY 64x64 pieces
* NOT SO EASY 32x32 pieces
* DIFFICULT 16x16 pieces --- real killer!
The picture and the difficulty level cannot be changed
during the program.
IFF2PCS uses a pop-up menu (which is operated just like a
standard Amiga menu, except that you do not have to move the
mouse to the top of the screen). The menu commands are:
* SHOW Shows the completed picture.
* CHECK Combines what you have with the actual picture to
give you an idea of how close you are. Pieces
that are in the correct place will appear as
blanks, while pieces that are placed incorrectly
will appear messed up. CHECK will also tell you the
time that has elapsed since you started the puzzle,
and will let you know if the puzzle is solved.
* HELP Provides some minimal help. (This command might not
work if the system is low on chip-memory.)
* QUIT Quits...
Pieces are grabbed by clicking the left mouse button and
rotated by clicking the right mouse button once the piece is
grabbed. Pieces can be rotated 90 degrees clockwise only;
you might need to click the right mouse button twice or
three times to get the correct orientation.
IFF2PCS is a chip-memory hog. It will attempt to open an
interlaced screen as large as the user's Workbench, and with
a 16-color picture, it might use more than 200K of chip
memory.
Many thanks go to D. John Hodgson, Tom Rokicki, and Helene
(Lee) Taran, whose code fragments I used in IFF2PCS.
