INTRODUCTION
HAMLAB PLUS is an image format conversion utility. It can read
bit-mapped images in many formats, perform some basic operations on
them, reduce them to a native Amiga display mode, and save them in
Amiga IFF format. It is intended mainly to read images with more
colors and higher resolution than are displayable on Amigas (JPEG
files and 256 color GIFs, for example) and to reduce the number of
colors in the image until the Amiga can display it, preserving
as much of the original image's quality as possible.
HAMLAB PLUS has many options: for the final format, you can choose
from dozens of combinations of resolution, number of colors, and
other factors, plus you can crop, resize, or adjust the colors of
the image in the process of converting it.
HAMLAB PLUS is modular: it uses separate "filter" programs to read
images, and new filter programs can be added to support other
formats without requiring the main program to be updated. Similarly,
HAMLAB PLUS can "export" to several formats using similar "exporter"
programs.
HAMLAB PLUS is flexible: it has a full Amiga point-and-click
user interface with an AmigaOS Release 2 look and feel, plus
it can be run in a simple batch mode from the command line, and
it has a powerful AREXX command set.
Finally, HAMLAB PLUS is extremely configurable: you can configure it
to start up with your preferred settings, plus you can tailor its
operation so that it utilizes as much or as little of your
system's RAM and disk space as you wish.
DOCUMENTATION ROADMAP
The HAMLAB PLUS documentation is supplied on disk in plain text,
formatted for 70 columns, with form feeds between sections. When
making a hard copy, I recommend allowing a 1 inch left margin (10
columns in pica) for punching holes to insert into a binder.
The topics are organized as follows:
intro.doc Introduction, roadmap, legalese
acknowledgements
userman.doc Quick start, setup, operation
cmd-ref.doc AREXX / config file command reference.
filt-ref.doc Filter and exporter reference.
