Short: Gd 1.1.1 A GIF conversion library, WWW Author: Tom Boutell, boutell@netcom.com Uploader: Joop vandeWege Medew ENTO WAU NL (Joop van de Wege) Type: gfx/conv Architecture: m68k-amigaos Modifications to the makefile (Aztec) are done by me, nothing else is changed. The archive includes the full source + the executable for Webgif. The original 'readme' follows below. The original makefile got lost in the process, but can be retrieved from the authors www-site. The supplied application 'Webgif' allows you to make transparent and interlaced GIF's for use with the various WWW browsers. Options are done a bit different than on the Amiga usually. It is not '-t0' but '-t 0' to specify that color index zero should be the transparent color. Anyone with a bit of programming experience should be able to modify the program to behave more like we are used to. -------------------------------------------------------------------- This is the gd gif-manipulating library, version 1.1.1. It was created to allow graphs, charts and the like to be generated on the fly for use on the World wide Web, but is useful for any application in which custom .GIFs are useful. It is not a paint program; it is a library. If you are looking for a paint program for the X Window System, check out David Koblas "xpaint", available by anonymous FTP from ftp.netcom.com in pub/koblas. (I'm just a fan of Dave's code.) "What's new in gd 1.1.1?" Numerous bug fixes, documentation improvements, and the webgif utility. See gd.html for details. "What was new in gd 1.1?" -- Polygon drawing and filling -- Brushes -- Tiles -- Line styling (even with brushes...) -- Interlaced GIFs (hello, Netscape!) "Where's the manual?" Load gd.html into your web browser. Print it if you like, but every single reference to a function is a hyperlink, so the manual is especially good when read online! COPYRIGHT 1994 BY THE QUEST CENTER AT COLD SPRING HARBOR LABS. Permission granted for unlimited use, provided that the Quest Center at Cold Spring Harbor Labs is given credit for the library in the user-visible documentation of your software. If you modify gd, we ask that you share the modifications with us so they can be added to the distribution. See gd.html for details. gd has been compiled in various forms on all major platforms. It is happiest on a machine with 32-bit addressing and a proper stack (ie, anything running Unix, VMS, Windows NT or any other modern operating system), but is entirely usable under DOS and Windows. Note, however, that the flood-fill routines are mildly recursive and may fail on machines with tiny stack areas. Also, the fonts require a significant amount of memory (they are optimized more for speed than for size), but they need not be linked by applications that do not use them. Otherwise the code is highly portable and has been written in pre-ANSI C to ensure easy compilation on all platforms. Full documentation is provided in HTML (World Wide Web) format in the file gd.html (part of this distribution). You can access the latest version of the file at the URL "http://siva.cshl.org/gd/gd.html". If you are unfamiliar with the World Wide Web, consult the Frequently Asked Questions posting of comp.infosystems.www.users for more information on where to locate a hypertext browser. The text-based browser "Lynx" does a particularly good job of navigating the manual and will run on nearly anything. If you don't have the patience to consult the manual first, build and examine gddemo.c (see the Makefile) and run it. It will read in demoin.gif and output demoout.gif, which you will want to examine with your GIF viewer to see the results.
