  14. What's it do?                                              @[
  15. -------------                                              @[
  16. It converts IFF pictures into an ASCII representation.
  17. The program will antialiase the text by selecting the      mmmmmmmmmmmmmi
  18. best characters to make the edge.  Characters are also     @A****M@****@[
  19. selected for their density when shading.                   @[    ]@    @[

  22. -------------                                              Y@_  _@@W__W@`
  23. The program can be invoked from the shell in the normal    'M@@@@A~*@@A`
  24. way or by running the arexx script use either:               '~~`

  26. ilbm2ascii [ilbm-file] > [ascii file]
  27. rx ILBM2ASCII.rexx FROM [ilbm file] TO [ascii file]
  28.                                                            @@@@@@@@@@@@@[
  29. If you have ARexx running you can double click the icon    ~~~~~~~~~XX@@[
  30. and start it from the Workbench and select the picture         __mW@A*~`
  31. and destination file using file requesters.                _mW@A*~`
  32.                                                            @@b_.
  33. How it works:                                               ~V*@@ms_.
  34. ------------                                                    '~V*@@ms.
  35. The program looks at pixel blocks of 2x3 pixels and        mmmmmmmmmmW@@[
  36. selects a character that best matches that block.          *************!
  37. Consequently the ASCII picture will be much bigger and
  38. and a differnt aspect ratio than the original IFF.         @@m_    ims.
  39. You may want to adjust your IFF before conversion to       @PV@W.  !*M@b
  40. compensate for this.  If you want to know more then have   @[ '@W.    V@[
  41. a look at the source that's included.                      @[  '@W.    @[
  42.                                                            @[   !@@s__W@`
  43. Preparation of the pictures:                               @[    '*@@@*`
  44. ---------------------------                                s_
  45. The program assumes that any non background colour is      M@@Ws_
  46. a colour.  For this reason you should use 2 colour           ~V@@@Wm_
  47. images.  If you want to convert images with more colours       @['~*@@Wm.
  48. then load them in to your favourite imgage processor           @[   _d@@[
  49. and dither a 2 colour image from that.  ILBM2ASCII will        @bmW@@*f~
  50. select a character whose density best matches the dither.   ,_m@@@*f~

  55. The Conversion Table is inspired by Jorn Barger's         i@!    d@!   MW
