This document applies to version v2.3.0 of ImageStudio which is
Copyright (C) 1994,1995 Andy Dean and Graham Dean.
Important Points
----------------
o The Aminet distribution of ImageStudio comes in two
archives named "ImageStudio_1.lha" and
"ImageStudio_2.lha". Both archives are needed for a
full installation, although "ImageStudio_2.lha"
currently only contains the documentation and
example pictures.
o "ImageStudio_1.lha" should be unarchived onto a FFS
floppy disk named "ImageStudio_1" and similarly for
the "ImageStudio_2.lha" file in order for the install
script to work correctly.
o Registered users of v1.x.x of ImageStudio can upgrade
to a fully functional version 2.3.x from this
distribution.
New for v2.3.0
--------------
o Added CyberGraphX support for viewers and program
preview.
o Changed distribution method - the program is no
longer available directly from the authors and now
comes with a printed manual.
o Few minor improvements and bug fixes.
Brief description
-----------------
ImageStudio is written for the casual graphics user who wishes to
convert or manipulate various graphics formats on a modest Amiga
system. There are several commercial offerings available, however the
casual user is paying a lot of money for many facilities and options
they would probably never use.
Bitmap graphics, by their nature, usually require large amounts of
RAM. One of the main objectives of ImageStudio was to reduce this
burden by utilising virtual memory - most users have more spare hard
disk space than spare RAM.
ImageStudio works with several buffers at any one time (dependant on
how many levels of undo are specified), each of these buffers can hold
either colour-mapped or 24-bit images.
ImageStudio comes with a fully featured ARexx port, which allows the
writing of macro scripts to automate repetative processes and also
allows communication with other ARexx aware programs. Again, ARexx has
the reputation of being "something pretty difficult", so we've
simplified the use of ARexx in ImageStudio by allowing the user to
create, edit and run scripts entirely within ImageStudio - ImageStudio
even provides a blank template as a starting point for each new script.
Machine requirements
====================
ImageStudio requires the following system to run:
* Workbench 2.04 or above.
* Around 1 megabyte of free memory.
* Several megabytes of free hard disk space.
If ImageStudio is run on an AGA machine (A1200 or A4000), it will
use the new display modes and palette routines to improve the quality
of the internal viewer images.
List of features
================
General:
* Full 24-bit image buffers, with optimizations for colour-mapped
(palette based) images.
* Up to 100 levels of undo / redo.

* Fully featured, easy to use, ARexx interface.
* Full CyberGraphX support for viewers and preview.
* Operations applicable to the whole image or a selected region.
* Up to 256 greyshade or colour preview window (with optional dither).
* Zoom on preview window.
* Internal / external viewers (external for third party 24-bit
graphics cards).
* Loading / saving / manipulating of AGA image formats (e.g. 256
colours, HAM8) on non-AGA machines.

unregistered version).
* Copy / paste to / from the system clipboard.
* Runs on all Workbench 2.04+ Amiga's - utilises AGA chipset if
available.
* Online AmigaGuide help, as well as ASCII, TeX `.dvi' and
PostScript documentation.
