Application Suite: ChangeFSI


File types accepted by ChangeFSI

ChangeFSI will convert any of the following image formats into the sprite or JPEG format. You can choose the type of RISC OS sprite that is created by setting the Output Options. If no special output mode is chosen, ChangeFSI produces a sprite that is compatible with the current display mode.

Additional notes

If you get a 'Number too big' error message while trying to display a TIFF file, or 'Division by zero' with an IFF file, then try setting the 'Ignore source pixel size' and/or 'Ignore pixel size' options. Also try setting these options if the proportions of an image (for example from an IMG file) are not what you expect.

There are some JPEG files available which don't conform to the standard convention. Although some of these files are accepted by ChangeFSI, others will not be. If you find this to be the case try setting the file's type to JPEG (C85) before giving it to ChangeFSI.

A couple of hints on memory usage
If you're short on memory, Drag the Next slot (in the Tasks display window) down to 320k. If you're converting wide images (e.g. PhotoCD images up to 3072 pixels wide) increase the Next slot to 500k or more.
