Sketcha V1.0   (C) 1999 by Edwin Blink.   Icons by Ray Wolfe.


Sketcha is a pc utility that allows more icons to be used in the Avigos
build in sketch application. By making a avigo rom patch and importing
the extra icons into the rom also.
Icons are imported into the existing icon bank so no extra memory is
wasted for the new icons.

Sketcha is FREEWARE ! 

Instructions
============

1 Extract this zipfile into a new folder (called 'sketcha')


2 copy the Avigo romupdate file 'English_V1004.pgm' or any other language
  version of rom version v1004 into this folder. You can get the V1.004 rom
  update at the TI website if you don't have it.

  Note: Older romversions before V1.004 won't work ! 
        Make sure the .pgm file is copied and not moved. Otherwise you won't
	have a backup.
  
3 drag and drop a romfile '.pgm' or '.rom' file ontop of rompatch.exe
  this will patch the avigo romfile so the sketch app will have 60 additional
  stamp icons to use for your sketches without taking more memory.

  Note that if no icons were imported and the avigo rom is updated the
  additional 60 icons will all be the light bulbicon.

4 drag and drop .alb or a .pgm file (1.31Mb with language data) ontop of 
  sketcha.exe to import the new icons into the .alb/.pgm file.

  note: Icons are imported from the 'icons.bmp'file which must be in the same 
        directory as the .alb/.pgm file.

5 update Avigo with the .pgm or .alb file

Optional:
  
6 If you're planning to change the 60 new icons frequently then you might
  consider to use 'splitrom.exe' to split the 1.31Mb romfile with integrated
  language data (which contains all icons) into a seperate .rom rom file and a
  .alb language data file.
  use the .alb file the next time at step 3 and at step 5 then you only need to
  send 320K of data to your Avigo instead of 1344K !

Final note: If you're using sketcha with avsim simulator make sure you
            delete the 'avsim.sav'file in the avsim folder.
            When this is not done then the icons will not be displayed
	    Since the languagedata/icons are only updated when the
            'Avsim.sav' file is created.

Thanks go to Ray Wolfe for bringing up the idea of sketcha and for supplying
the icons in the 'icons.bmp' file.

Enjoy
