- Version
- =======
- 1.21 (17-Jul-95)
-
- Purpose
- =======
- Reads TIFF files and converts them into 32-bit sprites (16.7 million
- colours).
-
- But ChangeFSI does that, doesn't it?
-
- Well, yes, most of the time, but ChangeFSI doesn't cope with all TIFFs. In
- particular, it doesn't cope with multi-channel TIFFs such as those exported
- by PhotoShop 3 on the PowerMac. Tiffin is likely to read just about any valid
- TIFF file thrown at it. You can then drag the sprite into ChangeFSI for
- scaling or taking down to fewer colours.
-
- Specifically, Tiffin should work for all TIFFs following the 5.0 or 6.0 TIFF
- spec.
-
- Use
- ===
- It's simplicity itself: When run, it installs its icon on the right side of
- the icon bar. Drag a TIFF file to it (it must be filetyped as a TIFF), and
- after a short delay you will be presented with a Save as box containing a
- 32-bit sprite which you may drag to disk or another application.
-
- There is an "Interactive" option on the iconbar menu, which is ticked as
- default. If you untick this, the sprite file will be written back over the
- TIFF source without asking for confirmation. This is useful if you have an
- entire folder full of TIFFs you want to convert. MAKE SURE YOU HAVE A BACKUP
- OF THE TIFFS FIRST - in case you change your mind. And be warned that,
- because there is no compression in RISC OS sprite files, the resulting files
- will almost certainly be larger than the TIFF source files.
-
- Clicking on the iconbar icon will give you an error box showing the version
- of LIBTIFF being used. See below.
-
- LIBTIFF 3.4beta
- ===============
- Tiffin uses my own port of the TIFF support library written and placed into
- the public domain by Sam Leffler of Silicon Graphics Inc. When I have tidied
- my port up a little the RISC OS version of the library will be made
- available, and, hopefully, integrated into the sources at SGI's FTP site.
-
- Toolbox
- =======
- To my knowledge, this is the first Freeware application to be made available
- that uses the new Toolbox modules that come with Acorn C/C++. For this
- reason, a copy of !System is supplied with Tiffin for you to integrate with
- your own !System in the normal way. You will need to do this before Tiffin
- will run.
-
- Requirements
- ============
- Tiffin will only run on RISC OS 3.50 or later. This is because it produces
- 32-bit sprites unknown to previous versions of RISC OS, and because it uses
- dynamic areas.
