- Short: Image processing program v2.0.0 Part 2 of 2
- Author: Andy Dean and Graham Dean
- Uploader: adean@eleceng.ucl.ac.uk
- Type: gfx/conv
-
- This document applies to version v2.0.0 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.
-
- o "ImageStudio_1.lha" should be de-archived 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 This distribution completely replaces the v1.2.1
- distribution archive "ImageStudio.lha".
-
- o Registered users of v1.x.x of ImageStudio can upgrade
- to a fully functional version 2.0.0 from this
- distribution.
-
- New for v2.0.0
- --------------
- o Added ARexx.
-
- o Added AmigaGuide online help.
-
- o Added program Iconify.
-
- o Added AppIcon for drag and drop file loading.
-
- o Added hook functions to ASL screenmode requesters to allow
- refreshing in the background.
-
- o Added current filename to the preview window title bar.
-
- o Added the ability to read corrupt files upto the point at
- which they become corrupt.
-
- o Standard Commodore Installer script.
-
- o Changed HAM remapping tables when using the internal 24bit
- viewer - no more "Remapping..." waits.
-
- o Changed preferences window.
-
- o Removed GIF save.
-
- 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

- * Full 24-bit image buffers, with optimizations for colour-mapped
- (palette based) images.
- * Up to 100 levels of undo / redo.
- * User configurable virtual memory.
- * Fully featured, easy to use, ARexx interface.
- * User saveable preferences.
- * Operations applicable to the whole image or a selected region.
- * Up to 256 greyshade 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.
- * Max image size of 32000 x 32000 (limited to 250 x 250 in the
- 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
