Short: Image processing/conversion program v1.2.1 Author: Andy Dean and Graham Dean Uploader: adean@eleceng.ucl.ac.uk Type: gfx/conv This document applies to version 1.2.1, written on 7th December 1994, Copyright (C) 1994 Andy Dean, Graham Dean. New for v1.2.0 -------------- o Improved speed of preview redraw. o Added greyscale JPEG read / write. o Improved speed and quality of HAM6 and HAM8 file creation. o Improved speed and quality of 24bit internal viewer. o Now uses ASL screenmode requester with Workbench2.1+. o Added dynamic range expansion effect. o Now sets program stack size within the program - no need to set the stack from the CLI. o Fixed bug which caused the FlipX effect to work incorrectly with 24bit images. o Fixed bug which caused non-AGA Amigas to think that they could view 64, 128 and 256 colour pictures directly. o Few minor bug fixes and improvements. New for v1.2.1 ~~~~~~~~~~~~~~ o Changed error in documentation that stated that we accept cheques drawn on non-UK banks. WE ONLY ACCEPT CHEQUES AND POSTAL ORDERS FROM THE UK. If ordering from outside the UK, we suggest an international money order - apologies for any confusion caused. There is no change to the program over v1.2.0. 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. For a detailed description of colour-mapped and 24-bit images, See Image types.

This program (or parts of it) may not be included or used in commercial programs unless by written permission from the authors. 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. * User configurable virtual memory. * 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 3rd 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. * On disk AmigaGuide and ASCII text documentation. The registered version also includes TeX `.dvi' and PostScript files. * Multi-level help error requesters. * Standard Workbench2 interface. * Public screen. * Requires no third party libraries or utilities. Import: * IFF-ILBM formats (Standard palette based, HAM6, HAM8, extra halfbright, ILBM24) * BMP * GIF (conforming to GIF87a) * JPEG (conforming to JFIF standard) * PCX * Targa * Any installed Amiga datatype (with Workbench 2.1+) Export: * IFF-ILBM formats (Standard palette based, HAM6, HAM8, extra halfbright, ILBM24) * BMP * EPS * GIF (conforming to GIF87a) * JPEG (conforming to JFIF standard) * PCX * Targa Colour Balance: * All operations are available to the R,G,B components separately. * Brightness * Contrast * Gamma Convolution: * Built in convolutions: Blur, Sharpen, Emboss, Raise, Edge detect. * User definable convolutions, load and save to disk. Effects: * Built in effects: Dynamic range expansion, FlipX, FlipY, RollX, RollY, Negative, Greyscale, Highlight, Shadow, Random, Pixelize, Remove isolated pixels. Scale: * Crop to selected region. * Increase / decrease scale by percentage or absolute image size. * Simple scale or colour averaged. Colour reduction: * Increase colour mapped images to 24-bit. * Decrease number of colours in 24-bit or colour mapped images via Heckbert median cut algorithm. * Dithers available for colour reduction: None, Floyd-Steinberg, Burkes, Stucki, Sierra, Jarvis, Stevenson-Arce. Palette: * Edit palette colours and ranges. * Save current palette. * Force palette onto current image, dithering if necessary (all dithers available). Shareware version ================= To encourage users to register, the freely distributable version of ImageStudio is limited to loading in pictures upto 250x250 pixels. All other operations are available. For details on how to register, See How to register. The authors *********** ImageStudio was written by Andy Dean and Graham Dean.
