Short: Universal picture viewer. New: faster color reduction, file requester Type: gfx/show Author: jow@hcast.franken.de Uploader: jow@hcast.franken.de ---------------------------------------------------------------------------- NEW FEATURES IN THIS VERSION: * The color reduction from 24 bit down to 8 bit is faster. * Workbench users will now be offered a file requester if they start JIV without file parameters. * The slide show mode can now be paused. * A few minor bugs are gone, others have undoubtedly been introduced. ;) ---------------------------------------------------------------------------- JIV is a picture viewer. I can imagine that you're wondering now why I had to write yet another one... well, here's a list of features that should answer your question: · JIV supports many different file formats: - GIF (full GIF87a standard plus a subset of GIF89a). - BMP (MS-Windows and OS/2 variants, currently only uncompressed). - IFF-ILBM (including HAM6, HAM8, EHB and 24bit formats). - PNM pictures (PBM, PGM and PPM in both binary and ASCII format). - PCX (8bit/VGA, 24 bit, monochrome and _some_ 4 bit) - JPEG/JFIF, if the JPEG CODEC is installed. - a reasonable subset of the TIFF 6.0 standard, including 1, 8 and 24 bit pictures in the compression types 1, 5 and 32773. JIV does not support the so-called "NeXT TIFF" format yet, but I'm working on the problems involved. Patience, please. :) · JIV supports several types of display hardware: - all native graphics chipsets (OCS, ECS and AGA). - Cybergraphics emulation. - A2024. - Picasso-II/Village emulation. - Generic mode, should work with every graphics board that emulates Workbench/Intuition. Tested with the Picasso-II emulation and the Cybergraphics emulation. · JIV supports displaying over-sized images using autoscroll. · JIV supports multiple filenames and AmigaDOS pattern matching. · JIV can dither pictures that use more colors than your display hardware supports. · JIV offers an endless/slideshow mode that can be used for (non-interactive) advertising, for example in a shop window. Please note that JIV is probably not the best choice for "small" Amiga configurations. It will need a lot of memory and (in some cases) quite a bit of computing power as well. The minimum configuration for JIV is: · 68000 or better. · AmigaOS 2.04 (V37) or better. · 1 MByte or more of RAM. This configuration should allow you to view small to medium-sized pictures (640x480x8 should just be possible). The suggested configuration for JIV is: · 68030 or better. · AmigaOS 3.1 (V40) or better. · 4 MBytes of RAM or more. · Hard disk drive. This configuration will allow you to view most pictures you're likely to find. A bit more RAM wouldn't hurt, though. :-) And of course you'll need a graphics board if you want to display true-color pictures without dithering. Distribution License This version of JIV may be distributed freely for non-commercial purposes only. You must distribute the entire archive INTACT and UNCHANGED, that is, you are NOT allowed to add files to the archive or remove files from the archive or change files in the archive. Specifically, you're allowed to: · Distribute JIV on floppy-disk-based collections of PD software. · Distribute JIV on CDROM-based collections of PD software IN ARCHIVED FORM ONLY, unless you obtain a specific license from the author. · Distribute JIV electronically, for example through email or FTP, or through BBS systems. BBS sysops, do NOT add those pesky BBS advertisments to the archive! Specifically, you're NOT allowed to: · Distribute parts of the archive or changed/patched versions of the files in this archive. · Distribute JIV on CDROM in ready-to-run form, unless you obtain a specific license from the author first. · Distribute JIV in any form on CDROMs that contain picture collections, unless you obtain a specific license from the author first.¹ · Distribute JIV bundled together with a commercial product (software, hardware or other), unless you obtain a specific license from the author first. I have been informed that in the U.S. a patent has been granted for the LZW compression algorithm used in the GIF file format, and that the patent holder requires a license fee for use of this algorithm in commercial software (including shareware). Therefore I will not ask for any shareware fees from U.S. users of JIV. Please do not confuse this distribution license, which details the terms and conditions for DISTRIBUTING JIV, with the shareware license which details the terms and conditions for USING JIV. ¹ Permission is granted to include ARCHIVED versions of JIV on the following CDROMs even if these CDROMs contain picture collections: · Aminet · Saar/AMOK Angela Schmidt has my permission to install JIV in both archived and ready-to-run form on her Meeting-Pearls CDROMs. Fred Fish has my permission to install JIV in both archived and ready-to-run form on his FreshFish CDROMs. Todo: · support for additional image file formats: - Icon - XBM - Targa - others · Datatype support · AREXX port · GUI · Image manipulation and format conversion. Known problems: · If you're using an A4000/040 kickstart file on a computer with a CPU <= 68020, the DISPLAY=GENERIC may crash your machine. This is not a bug in JIV. The BestModeIDA() system call in the A4000 kickfile seems to contain an instruction that is only available on 68030 and above. As far as I can tell, there are only two kinds of people who use A4000 kickstart files on CPUs below 68030: former registered developers and software pirates.
