It converts IFF pictures into an ASCII representation.
The program will antialiase the text by selecting the      mmmmmmmmmmmmmi
best characters to make the edge.  Characters are also     @A****M@****@[
selected for their density when shading.                   @[    ]@    @[

The program can be invoked from the shell in the normal    'M@@@@A~*@@A`
way or by running the arexx script use either:               '~~`

If you have ARexx running you can double click the icon    ~~~~~~~~~XX@@[

The program looks at pixel blocks of 2x3 pixels and        mmmmmmmmmmW@@[
selects a character that best matches that block.          *************!
Consequently the ASCII picture will be much bigger and
and a differnt aspect ratio than the original IFF.         @@m_    ims.
You may want to adjust your IFF before conversion to       @PV@W.  !*M@b
compensate for this.  If you want to know more then have   @[ '@W.    V@[
a look at the source that's included.                      @[  '@W.    @[

The program assumes that any non background colour is      M@@Ws_
a colour.  For this reason you should use 2 colour           ~V@@@Wm_
images.  If you want to convert images with more colours       @['~*@@Wm.
then load them in to your favourite imgage processor           @[   _d@@[
and dither a 2 colour image from that.  ILBM2ASCII will        @bmW@@*f~
select a character whose density best matches the dither.   ,_m@@@*f~

ILBM2ASCII is a C coded FAST program based on IFF2ASCII
which was an AMOS program by Matthew Stratfold. Who also   mmmmmmmmmmmmmi
