-
- (How about more 40 column manuals!!)
- (With no tabs this time)
-
- What is it?
- -----------
-
- PGSHOW is a program that allows you
- to view Portfolio Graphic Files on
- the Atari Portfolio. These files
- are now compressed and have a .PGC
- extension. If you have old PGF
- files, please compress them with
- PGCOMP.EXE.
-
- How do I use it?
- ----------------
-
- SYNTAX: PGSHOW <filename> [seconds]
-
- Seconds is a value from 0 to 255.
- If you specify 0 secs or leave off
- the seconds, PGSHOW will wait for a
- keypress.
-
- Multiple filename-seconds pairs can
- be specified on the command line.
- PGSHOW will show one file after the
- other.
-
- The default file extension is .PGC,
- it can be omitted.
-
- Where do I get .PGC files?
- --------------------------
-
- There are 6 .PGC files included in
- the distribution:
-
- GORBY.PGC Gorbachev
- FUJI.PGC Atari Computer Logo
- PORTF.PGC Portfolio Logo
- BOMB.PGC A bomb with lit fuse
- USA.PGC A map of the U.S.
- SPIRAL.PGC A rectangular spiral
-
- You can also create your own .PGC
- files with tools that will be
- forthcoming from Software Vineyard:
-
- PGEDIT A .PGC file editor that
- runs on a desktop PC.
- Has it's own GUI and some
- nice features. Requires
- VGA, 512K, and Microsoft(R)
- compatible mouse.
- (Available now)
-
- PGDUMP A screen dump utility to
- dump graphic screens from
- within other programs.
- (ETA January 1991)
-
- PGLIB A library of machine
- language routines to add
- to your own C programs for
- reading and writing .PGF
- files.
- (ETA January 1991)
-
- All of the above programs are going
- be Public Domain and free to all!
-
- PBASIC 3.1* will have commands to
- support reading, writing, and
- showing PGC files.
- (*PBASIC is (c)1990 BJ Gleason)
-
- The .PGC format
- ---------------
-
- The PGC (compressed) format was
- developed jointly by Don Messerli
- of Software Vineyard and BJ Gleason.
- The format is non-proprietary. The
- specification is in the file
- PGCSPEC.ZIP. We encourage all who
- are developing graphics applications
- for the Portfolio to support the PGC
- format. It is my hope that all PGF
- files be converted to PGC format and
- that people forgive me for jumping
- the gun with the PGF format. Some
- programs will continue to create PGF
- files. They can be converted with
- PGCOMP.ZIP
-
- What if I find bugs?
- --------------------
-
- Please report any bugs and send
- comments to Don Messerli
