- Requirements
- ============
- Sketch Pad requires at least RISC OS 3.10, 160k of memory at start up, and
- the toolbox modules, which are supplied with this. It works on the Risc PC
- and StrongARM, but you may need to be a 16 or 256 colour mode. Before you
- start, you should unpack the archive using !SparkFS or !SparkPlug.

-
- This program is SHAREWARE. This means that it is distributed in whole, for
- you to test and see if you wish to keep it. Feel free to distribute it to
- friends etc, provided the archive remains intact, and no profit is made.
- This program has a two week trial period. After that, you must either
- REGISTER, or delete this program.
- To register, send £5 (UKP), along with your name, address, and if possible,
- an email address, to the address below. If you do not have an email address,
- you should enclose a SSAE and a disc. You will be put on the registration
- list, receive the registered version with nag screen removed, and receive
- free updates via email on request. You will also have a clear conscience,
- and know that you are supporting software development for RISC OS computers.
- Please do not rip me off. After all, it's only £5. If you do not have
- internet access, and you want an update, you can send me a SSAE and a disc,
- and I will return the latest version.

- ============================================================================
- I may have borrowed a few icons, but these have all been altered quite a bit,
- and I hope those who created the originals will be flattered that I found
- them so well designed to use them in my own program. A special thank you to
- Doggysoft for their albeit altered NewerLook icons.

- InterGif 4
- ==========
-
- by Peter Hartley (K) All Rites Reversed
- Desktop front-end adapted from one by Iain Logan
-
- INTERGIF 4 is a program for making GIF images from 2-, 4-, 16- or
- 256-colour RiscOS sprite files, or from files produced with Iota
- Software's (commercial) animation program The Complete Animator. It
- can also convert from GIFs back to sprites.
-
-
- Get the latest version
- ----------------------
-
- The latest version of InterGif, plus more help information and full
- source code, is always available on the World-Wide Web at the address
- http://www.ant.co.uk/~peter/software/intergif.htm
- It's the twenty-seventh of October, 1996, as I'm writing these words
- (happy birthday, Anne): if it's long after that that you're reading
- them, you might want to see if there's a later version now available.
-
-
- Distribution
- ------------
-
- InterGif is NOT COPYRIGHTED and is NOT distributed under the GNU
- General Public Licence. For full information read the file
- !InterGif.Copying or go to the Web site.
-
-
- Features
- --------
-
- o InterGif runs either on the desktop, or from the command line (so
- I can produce the GIFs for my own Web pages, from the sprites
- which constitute their source, using a make file!).
-
- o InterGif has options for the transparency and interleaving
- features of GIF89a.
-
- o InterGif can take a sprite file (or an Animator file) containing
- several frames, and produce from it an animated GIF which Netscape
- 2.0 or later, MSIE 3.0beta1 or later, or ANT Fresco 1.22 or later
- will render as animated if it's inlined in a Web page.
-
- o InterGif will reduce its input to a smaller number of colours
- (unless you explicitly tell it not to) if it can get away with it,
- i.e. if only that many of the colours are used anyway.
-
- o It will also compress only the rectangle which has changed on each
- frame, so if your animation has a complex but stationary
- background, the background will only get compressed once.
- Deviousness and cunning are employed to minimise the final size of
- the GIF: so much so that many animated GIFs I've found on the Web
- have ended up smaller when run through InterGif.
-
- o It can also make GIF images from Draw files if used in conjunction
- with AADraw (see end).
-
-
- Desktop use
- -----------
-
- Pretty straightforward. Run !InterGif; drag your sprite file, Animator
- file, or GIF onto the left-hand bit of the window; set any options you
- want in the middle bit of the window; and save your GIF or sprite file
- out from the right-hand bit of the window. The options are:
-
- o Interlaced
- Produce an interlaced GIF: in other words, one which a Web
- browser can render quickly at a low resolution, filling in the
- details later as they arrive.
-
- o Looping animation
- Normally an animated GIF plays through once and stops. If you
- tick this option, you'll get an animated GIF that plays over and
- over again. This is a Netscape extension to the GIF format, but
- hopefully it will become a popular one -- both MSIE and Fresco now
- support it too.
-
- o One frame per file
- This splits up the input file into one output file per frame.
- Not, I admit, terribly useful, unless you need to import something
- into an application that expects lots of one-frame GIFs -- for
- instance, Sun's Java Animator applet. The names of the files are
- taken from the one you give, with any numeric part incremented as
- needed, so if you save a three-frame animation as frame001/gif,
- you also get frame002/gif and frame003/gif.
-
- o Keep source palette
- This disables InterGif's palette optimisations and ensures
- that the output has all the same colours, in the same order, as
- the input.
-
- o Frame delay
- This lets you set the frame rate, in centiseconds. The default
- is 8 centiseconds per frame (12.5 frames per second).
-
- o Transparency
- Choose None to get a wholly opaque GIF (no masking), Auto to
- get InterGif to use the sprites' masks (or the film's background
- colour); or you can specify a transparent pixel-value directly.
- (Hint: to find out what pixel-value a sprite pixel has, load the
- sprite into Paint, ensure its palette window is showing, click
- Menu over the pixel you want, and choose "Paint->Select colour".
-
-
- Command-line use
- ----------------
-
- For this, you'll probably want to copy !InterGif.intergif into your
- library directory.
- At its simplest, you can just type intergif and the name of your
- sprite or film file, and it'll be converted. Here's a full list of the
- options:
-
- intergif [-i] [-loop] [-s ] [-split] [-same] [-d cs] [-t [pixel]]
- [-o outfile] infile
-
- -i
- Produce an interlaced GIF
- -loop
- Looping animation
- -s
- Produce a sprite rather than a GIF
- -split
- One frame per file
- -same
- Keep source palette
- -d cs
- Frame delay in centiseconds
- -t
- Use automatic transparency (default is no transparency)
- -t pixel
- Use specified pixel as transparent
- -o outfile
- Filename for the output (default is <infile>/gif)
- infile
- A RiscOS sprite, Complete Animator or GIF file
