ImageStudio is written for the casual graphics user who wishes to convert or manipulate various graphics formats on a modest Amiga system. Features include :- * 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. * 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 * 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 ( upto ±100%) * Contrast (non to full) * Gamma ( + and - ) Convolution: * Built in convolutions: Blur, Sharpen, Emboss, Raise, Edge detect. * User definable convolutions, load and save to disk. Effects: * Built in effects: 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. Reduce to any number of colours 2-256 (not limited to powers of 2). * Methods of palette colour choice: Colour distance, highest count and weighted average. * Dithers available for colour reduction: None, Floyd-Steinberg, Burkes, Stucki, Sierra, Jarvis, Stevenson-Arce. Palette: * Save current palette. * Force palette onto current image, dithering if necessary (all dithers available). ** SHAREWARE **
