cadubi - Creative ASCII Drawing Utility By Ian
cadubi is an application written in Perl that allows you to draw
text-based images that are viewable on typical UNIX-based consoles.
Usually the applications that emulate these consoles support various
text modes, such as background and foreground colors, bold, and
inverse. This text art, commonly called "ASCII art", is used in various
places such as online BBSes, email and login prompts.

-s [W] [H]
--size [W] [H]
sets the size of the console for use with cadubi, where W is
number of columns and H is number of rows.

will move the ursor five spaces instead of one.

g Toggle bold mode.
v Toggle inverse mode.
Toggle blink (highly annoying).
t Enter text mode. This allows you to type like as if you were
using a normal text editor, and all the characters drawn
onscreen will use the same mode as the pen Pressing Esc will

Cadubi has a ’pen’ which describes the current mode. Properties of the
pen are the painting character, foreground color, background color,
bold, inverse, and blink. Whenever you paint or use the text mode, the
characters drawn on the screen will have the properties of the pen. The
current mode of the pen is shown at the bottom of the console and is
what will be drawn on screen when you paint. Typically, foreground
text colors are the same as background colors, unless the text is bold.
If the text is bold, foreground colors are usually lighter than the
background color, making text easier to read when the text has the same
foreground and background color. Refer to the Quick Help (control-’h’)
to see what the colors look like on your console.
Text mode is an extremely useful feature. Once in the text mode you can
type as if you were using a normal text editor, and all the characters
drawn onscreen will use the same mode as the pen. To enter text mode,
press the ’t’ key. To exit, press escape.
When cadubi reads a file, it will only read as much that will fit in
the workspace (the area of the console minus the bottom row [status
bar]). To gain more workspace, see the ’-s’ operator in section

The color codes are case-insensitive. The following color codes can be
chosen as fore- or background colors:
0 or N - Normal (standard text)
1 or W - White
2 or R - Red
3 or G - Green
4 or Y - Yellow
5 or B - Blue
6 or M - Magenta
7 or C - Cyan
8 or K - Black
Cadubi uses escape sequences for things like color. These may differ
from system to system. This means that the file generated by cadubi may
trash your console when viewed with for example cat. It is generally
safe to use the files on the same type of console as they were
