Short: Image processing program v2.3.0 Part 2 of 2 Author: Andy Dean and Graham Dean Uploader: adean eleceng ucl ac uk Type: gfx/conv Architecture: m68k-amigaos 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. * User configurable virtual memory. * Fully font sensitive interface. * 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. * Max image size of 32000 x 32000 (cropped to 512 x 512 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 PostScript documentation. * Printed and illustrated manual available separately. * Multi-level help error requesters. * Standard Workbench2 interface. * Public screen. * Requires no third party libraries or utilities. * Comes with printed and illustrated manual. Import: * IFF-ILBM formats (Standard palette based, HAM6, HAM8, extra halfbright, ILBM24) * IFF-DEEP * BMP * Datatype * GIF (conforming to GIF87a and GIF89a) * JPEG (conforming to JFIF standard) * PCX * PNM (PBM, PGM, PPM) * QRT (DKB, POV) * SGI * Targa * TIFF * VMEM Export: * IFF-ILBM formats (Standard palette based, HAM6, HAM8, extra halfbright, ILBM24) * IFF-DEEP * BMP * EPS * GIF (conforming to GIF87a and GIF89a including transparent colour) * JPEG (conforming to JFIF standard) * PCX * PNM (PBM, PGM, PPM) * QRT (DKB, POV) * SGI * Targa * TIFF * VMEM Colour Balance: * All operations are available to the R,G,B components separately. * Brightness (0% to ±00%) * Contrast (non to full) * Gamma ( + and - ) Convolution: * Many supplied convolution filters. * 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 will crop pictures to 512x512 pixels. All other operations are available.
