1. History.
This program has been developed, using 'plop' as a base, to enable
me to display the HAM Overscan pictures I created with 'DigiView'.
This program will display most resolutions, both NTSC and PAL. At
the moment however the HiRes Overscan resolution is not supported.
Version History : V 0.89L, March 1989.
Lattice C, Some problems with the screen (Flash)
ported source from Aztec to Lattice.
Needed some polishing to satisfy the
worlds pickiest Compiler.
V 0.90L, April 1989.
Lattice C, Solved screen flashing. Conformed the
source to the ANSI C standard!. (more
or less anyway). Exchanged the printf
statements for a function Schrijf(),
which conserves memory and is just as
fast anyway.
V 0.91, May 1989
Lattice C, Found problems with Overscan and 1.3.
Overscan wasn't recognized. Solved by
using RemakeDisplay() after setting
correct overscan values.
V 1.0, August 1989
Lattice C, Some problems that crept up have been
solved, as well as enhancements made.
- Interlace problem solved.
- Extra-HalfBrite support added. Needs
a CAMG chunk in the file though. If
no CAMG chunk then HAM mode is set.
( See the IFF specs on 'Fish 185'. )
There should be A CAMG chunk in all
ILBM's.
- HiRes OverScan problem not solved.
Seems to be Systems bug.
2. Usage
Usage : PicView [<DURATION>] <FILENAME>.....<FILENAME>
How to use this program? Well it is fairly simple. You may specify
the duration the picture is on the screen in seconds. If you don't
specify the duration, the program defaults to a 5 second duration.
For every picture specify it's filename. If the picture is not in
the current directory you must also specify it's complete path.
To clarify this I will give some examples.
Display pictures pic_a pic_b pic_c pic_d and pic_e in the current
directory for 10 seconds each.
Command line : PicView 10 pic_a pic_b pic_c pic_d pic_e
Display pictures pic_a pic_b and Pic_c on drive df1: for 5 seconds
each. (Remember : 5 seconds is the program's default displaytime).
Command line : PicView df1:pic_a df1:pic_b df1:pic_c
Display pictures pic_a on drive df1:Pictures and pic_b in df2:show
for 20 seconds each.
Command line : PicView 20 df1:Pictures/pic_a df2:show/pic_b
Requirements:
- A standard Amiga with 512KByte of memory will suffice. Make sure
though, that there is enough free memory or the program aborts.
The program should support all regular Amiga devices. I tested it
with DF0: to DF3:, VD0:, VDK:, RAM:, CARD: and DH0: to DH2:. It is
compatible with both WorkBench 1.2 and 1.3. I haven not tested it
with 1.1 though. It also works on Amiga 2000 with 1 MB of ChipMem.
(Rev 6 and higher.)

5. BUG-Reports.
Known Bugs:
- PAL HiRes Overscan is not fully supported. The 'PAL' section of
the screen stays black. (On an Amiga 1000, as well as the 2000)
Irritating. This should not happen. Seems to be a systems bug.

No phone, not since some guy woke me at 04:00 AM ( My local time,
not his!). So, if you feel it is that urgent to call me you won't
mind taking the trouble of finding out my phonenumber. But PLEASE!
check the time-differences. I can get pretty uncooperative when
called out of bed in the middle of the night!
