!ChangeFSI/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
ChangeFSI is a high quality image mastering program which understands many
image formats. The image may be scaled, rotated by 90 degrees and sharpened.
Images can be made for any RISC OS screen mode in monochrome, greyscale or
colour. Various image processing algorithms can be applied to the image.
You (the operator) set up the program's options using the menus and dialogue
boxes and then drop the source image file onto ChangeFSI's icon. The picture
will be computed (sometimes this takes a long time) and displayed for you to
see and save.
The document FSIinfo contains full information on the program. Brief
information is shown below.
The Scaling dialogue box allows choice of the scaling options.
=======
"Ignore Source Pixel Size" stops the program believing those image formats
which provide the pixel size (useful especially if the information is
wrong!). The pixels are all considered to be square and the same size as a
mode 27 pixel (2 OS units per side).
"Ignore pixel aspect" completely disables all the size information in the
program. Both source and output pixels are considered to be square.
"Lock picture aspect" prevents "Scale to fill" or "Custom" scaling changing
the aspect ratio of the picture: it will be small enough to fit in the
specified space.
"Scale to fill" will provide a full screen sprite for the current mode.
The "Custom" box allows for different scaling. Enter x ratio and y ratio in
the boxes below (default 1/4 in both axes) and turn the option on to use it.
If the righthand boxes are zero (empty), the lefthand boxes specify the size
of the final output.
The Processing dialogue box controls the image processing algorithms.
==========
"Expand Dynamic Range" will read the picture to discover how much of the
0-fullscale it actually uses and expand it to the full range.
"Disable Dithering" turns off the dithering: picture quality drops!
"Brighten Picture" causes ChangeFSI to produce a picture that is 16/15
brighter than it should be. In the case of light pictures this can produce
objectionable white patches.
"Pre-Sharpening" can be used either to actually sharpen an image (with
values in the range 10 to 20) or to compensate for the "fuzzyness"
introduced by dithering (values in the range 20 to 30).
"Smoothing" can be used to reduce noise in an image (range 3 to 10+), or to
blur an image (range 1 to 3).
The Output dialogue box controls the mode the picture is created for.
======
"1,2,4,8,16,32" These radio buttons represent square pixel modes (e.g. VGA)
"1,2,4,8,16,32" and TV standard modes (like mode 12) with "n" bits per pixel.
The selected mode is shown in the box to their right and this can also be
typed into for any specific mode. *NOTE* 16 and 32 bit output on the desktop
is only possible with a suitable OS.
"Use current mode" (the default) will make the picture for the current
screen mode - change desktop mode to change the target mode.
"Monochrome" the output is made into 1, 4, 8 or 16 greys for 1, 2, 4 and
8 bit per pixel modes respectively.
"Colour" (the default) the output is made using all the colours available
(this isn't very many for 1 and 2 bit per pixel modes!).
"Special" allows the choice of any of the "mode suffixes" described in the
FSIinfo document (see the end).
"JPEG" sets JPEG output, quality controlled by the quality box (between 1
and 100, 1 is low quality (very), 100 is high quality). Colour and monochrome
select appropriate JPEG options.
The !Run file is set up for colour pictures of around 3000 pixels across
maximum, monochrome pictures of around 9000 pixels across maximum. You will
need to increase the slot size for larger pictures. A file !RunBig is
supplied for very large pictures (or for small pictures with very large
colour space such as ALPIAR16).
ChangeFSI$Cache can be set to values larger than 128K to speed processing.
(In particular, JPEG files smaller than the value of ChangeFSI$Cache will
be read much quicker).
ChangeFSI$PCDIndex can be set to change which PhotoCD resolution is read.
