- Koala-Verter converts
- full-color Koala pad pictures
- into a black&white dot
- patterns which can print on a
- standard cbm 1525 graphics
- printer.
-
- Koala Printer reads in the
- converted pictures for
- printing, and allows the
- picture to be expanded in
- either vertical or horizontal
- directions.
-
- First, run Koala-Verter. The
- program willprompt for
- insertion of a disk
- containing Koala pics. Use
- the sample provided (jungle)
- or insert your own disk
- containing another program.
- then, press return .
-
- After reading and analyzng
- the picture, the Koala
- version will be displayed in
- color along with a table of
- the sixteen possible colors.
- Select a color to be
- extracted from the picture;
- black, for example.
-
- The next menu requests a
- dot-pattern to be substituted
- for the black areas. Select
- one, such pattern (a). The
- picture will be scanned
- bottom to top, extracting
- those black areas and
- creating a new picture
- containing the (a) pattern
- where black occurred in the
- Koala picture.
-
- Note that the pattern we
- substitute for colors in the
- Koala picture is a 2-by-2 dot
- pattern, allowing us 8
- possible choices for our
- black & white version of the
- picture. This method of
- representing shading
- information by means of dot
- patterns is called dithering.
- Most importantly, we have
- control over how the various
- color areas are represented
- in the final print. Being
- naturally creative, we can
- decide which areas should
- contrast and which should
- blend. In this way (read
- 'trial and error' here), we
- will find the combination of
- dots which best represents
- what the picture says.
-
- After extracting a color and
- viewing the results, we may
- accept it (by pressing
- return) or reject it by
- selecting another pattern to
- substitute.
-
- Note that the menu at the
- bottom of the screen may be
- toggled on and off using the
- f7 key so you can see the
- full area of the screen.
-
- Once an extraction has been
- accepted, it goes into the
- 'final' print. Each
- succeeding extraction will be
- added to the previous ones to
- build the picture. Color
- seperations could be made by
- saving and printing each
- extraction by itself.
-
- Experiment with
- pattern-substitution on
- various pictures to get a
- feel for what works.
- Experience suggests that
- single-dot areas don't print
- well on a 1525; clusters of
- dots two-or-more wide seem to
- work better. Row-to-row
- registration of dots will
- vary from printer to printer,
- also. When ready to print,
- press f1 to exit and save the
- picture. It will now be a
- full 8k high-resolution
- picture, loading at $2000.
-
- Load and run Koala Printer.
-
- NOTE: Koala Printer supports
- only 1515/1525/mps 801 or 803
- printers.
-
- Using the menu, load your
- dithered picture. Then view
- it. When viewing, any key
- takes you back to the menu.
-
- Now PRINT it.
-
- The picture will be turned
- sideways to better fit the
- paper and allow room for
- expansion. Unexpanded
- pictures, being smaller,
- print faster and are
- recommended for 'first
- drafts.' more importantly,
- the ribbon will last longer.
- You may exit from printing at
- any time by pressing the stop
- key.
-
- Upon exit from Koala-Verter
- and Koala Printer the 8k
- hi-res picture remains intact
- in ram at $2000, for those
- who wish to use it.

- In Turn, you will be rewarded
- with an all new, Version 2.0
- 'KOALA-VERTER/PRINTER' which
- features ultra hi-speed
- loading/printing, and dumping
- to various ascii
- dot-addressable printers
- without having to use the
- slower printing routines of
- the 1525 printer. Plus a
- complete set of
- documentation.
-
- Koala Verter/Printer is
- written entirely in assembly
- language via the MAE
- assembler. Koala Verter was
- originally destined to be a
- commercially available piece
- of software. However, this
- product was previously
- released to the library of
- the Commodore User's Group of
- Kansas City as part of an
- on-going HI-Res software
- utility library disk. Midwest
- Micro has decided not to
- market this product. Their
- loss is your gain!
