The best way to learn
about SIRTS is by examining one of our examples.
Next try creating your own! Start simply:
In the SIRTS generator text-box, draw a box of '1's centered on the page.
Your browser must support forms to use the SIRTS Generator. If your
operating environment offers cut-and-paste, you can save your design by
cutting and pasting it into any text-editor. You must use a mono-spaced font
to properly view the stereogram.
You can specify advanced options with '%%' as the first characters of a line.
All options are processed first and thus can appear anywhere in your input
region. The syntax for specifying an option is:
Note that color options are browser specific. They will only work on
browsers that support the
Basics
The Single Image Random Text Stereogram is based upon the same
principles as the Random Dot Stereogram. SIRTS are best viewed at a
distance of 18 to 24 inches from the screen.
Next, hit the 'submit' button. Voila! You are now showed the
finished stereogram.Advanced Topics
You can comment lines of the input field with '%' as the first character
of the line.

Here are some advanced examples of

construct.
Options
Here are the options currently supported:
level
: This specifies the default level of any non digit.
The default is level 0
. If you set this
level to a number between
0
and 9
then you
can have 'reverse' stereograms where the scene appears
behind screen unstead of infront of it.
depth
: This is a integer
value that lets you change the
depth of the stereogram. Anything below 5 is not recommended.
Default is 15
.
width
: This is the
final width of the stereogram in
characters. The default value is 70
.
symbol
: This is the
probability that a given random
character will be a printable symbol and not an alphanumeric
character. This value can range from 0
to 1
.
The default value is 0.4
.
space
: This is the
probability that a given random
character will be a white space. This value can range from
0
to 1
, but anything greater than
0.2
will make the stereogram very hard to resolve.
The default value is 0.02
.
color
: This specifies
how often to use color. 0
corrosponds to no color at all and 1
corrosponds to
all colored. Any real number with in that range corrosponds to that
much color. Default is 0
colors
: This specifies
which colors to use. It is a comma seperated field of colors
in the format: #rrggbb,#rrggbb,#rrggbb,#rrggbb
.
Default colors are a random range of over all colors.
fg
: This specifies the
foreground color of the characters
in the stereogram. The format of this color is #rrggbb
where r,g, and b are hexidecimal digits. The default is black.
bright
: This specifies a
color that should be
brighter than the other colors that will help you to resolve the
stereogram. The format of this color is #rrggbb
where r,g, and b are hexidecimal digits. The default value is
no bright color.
