Megaview is a shareware GIF(tm) viewer for use with the DCTV(tm) hardware
and was written by John R. McCormick of McCormick & Associates
Introduction
MegaView was written in pure 68000 assembly language for size and speed (mostly
speed).
I wrote MegaView because I was tired of not being able to see the large GIF
files that were being uploaded from the IBM world without either converting
the images to HAM, therefore reducing the resolution of the image, or using
a product such as Art Department Professional (by ASDG, inc, great product!)
to convert the image to IFF24 format (requiring 3mb or more of memory and
almost 800k of disk space for the IFF24 file).
Having my A500 with 2mb of memory pretty much left me stuck only able to
convert small GIF's.
With all the colors and the resolution available to me on my DCTV I was
still stuck. So I decided to make a GIF viewer that was both fast and small.
After much searching I found the information I needed to decode the GIF
files and produce the images on the DCTV, along with the information for
several other graphic file formats which will be implemented in future
versions of MegaView (registered version only).
The next major format to be incorporated into MegaView will be PCX
(PC Paintbrush files). Followed closely by BMP (Windows Bitmaps) and TIFF
files. Full scaling and graphic conversion (GIF to DCTV etc. will be
incorporated as I am able). All implementation will be in pure 68000/020
assembly language (I will only resort to 020 if I find it necessary for speed).
I would like to make MegaView the most versatile graphics viewer for the Amiga
but in order to do that I need your help. Though the shareware concept hasn't
worked too well in the past on the Amiga I have decided to give the Amiga
community another chance to prove that Amiga shareware software is appreciated
and that the Amiga community feels that shareware authors should produce
more software.
Future enhancements will be implemented based on my time and the hardware
available to me, I will very probably support the HAM-E board and other
24 bit video boards (maybe even Amiga video modes).
If you feel that this software is worth using please register it by sending
a check or money order (please allow extra time for personal checks) for
$15.00 (in US funds drawable from a US bank) to:
McCormick & Associates
3223 64th Avenue S.W.
Seattle, WA 98116
If you are out of the US please add an additional $5 US to cover postage etc.
I will send you the very latest version of the register version of the software.
Let's all support Amiga shareware, and keep shareware authors from defecting to
the IBM world!! Thanks.
INSTALLATION
copy mv into your C: directory
copy dctv.library and req.library into your libs: directory
By the way the only parameter that MV takes is the name of the file you want to
view so to see the file CONRAD2.GIF you would type:
MV CONRAD2.GIF
or MV if you want to select the file to display using a file requester
when the file is done displaying press either mouse button or press any key to
exit the program.
This program makes use the the REQ library by Colin Fox (of Pyramyd Designs)
and Bruce Dawson (of CygnusSoft Software), req.library is copyright 1989
by Colin Fox and Bruce Dawson.
