-
- [1] Synopsis
-
-
- randjpeg serves one purpose. Given:
-
- a directory containing many JPEG's
-
- produce a 256 colour RISC O S sprite of
- one of the JPEG's
-
- and cycle through all the JPEG's without
- reptition
-
- Thus it makes a good `random backdrop generator'
-
-
-
- [1.1] License
-
- This software comes with NO WARANTEE. It is distributed in
- the hope that it's useful. The author will not be liable
- for any incurred damages, directly or indirectly due to the
- use or inability to use this software.
-
- It is FreeWare, and remains the copyright of the author.
-
- The code to match a colour to the default wimp palette is
- based on a UseNet article:
-
- Message-ID: <12463@acorn.co.uk>
- Date: 30 Jan 92 12:20:23 GMT
- From: RWilson@acorn.co.uk
- Subject: How to find the closest colour out of
- the RISC OS 256
-
-
-
- [1.2] Requirements
-
- This software requires the SpriteExtension module supplied
- with RISC O S 3.6.
-
- It does not use ChangeFSI --- it has its' own quantisation
- code.
-
- Everything is RAM based, and it generates an intermediate
- 32-bit sprite, so be careful out there.

-
- [2] How to use
-
-
- Copy the contents of the archive onto a writable media (it
- generates a history file). Then edit the supplied !Run
- file so that it points to a directory containing some
- JPEG's.
-
- Double-click the !Run file.
-
-
-
- [2.1] Command line parameters
-
-
- The syntax is:
-
- randjpeg <directory> <history> <sprite>
-
- all parameters are necessary.
-
-
- <directory>
-
- This directory is scanned recursively for JPEG
- files each time the program is run. Thus it is
- safe to delete/create new sub-directories / JPEG's
- inbetween runs of the program
-
-
- <history>
-
- randjpeg creates this text file. It is a simple
- database of all the JPEG files processed so far,
- with one file name per line
-
-
- <sprite>
-
- This is the name of the sprite file that will be
- generated. The file will consist of a single
- 256 colour sprite, no palette, with the sprite
- named after the (leaf) name of the input JPEG

- [3] History
-
- Version 1.00 21-Jan-1996
- First release
-
-
-
- [4] Future improvements
-
-
- o Converts GIF's [either internally or via ChangeFSI]
-
- o Converts Sprites
-
- o Allow for multiple directories
-
-
- Well, these might get done, but seeing as I'll get the
- usual feedback from users of my stuff (e^(i.pi)+1), not
- likely to be done soon.
