Warp and weft expressions in Corel Painter
In Corel Painter, you need to use the weave pattern expression language to generate a weave. You may
find working with the pattern expression language more logical than working with very complex expanded
sequences. For more information see, “Reference: Expression operators” on page 768.
The following table includes an example of a traditional pattern expression expressed in the Corel Painter
pattern language.

To define a warp or weft expression
• In the Edit Weave dialog box, type an expression in the Warp box.
As you type a warp or weft sequence, the “Expands to n”message above the panel displays the length n
(number of digits) of the expression. This describes the number of threads in the sequence.
If Corel Painter cannot resolve the expression, the expansion length message displays “!” (error).
If you want to copy the Warp expression to the Weft expression, click the Tromp as Writ
(pattern) button.
Defining warp and weft color expressions
(Windows only)
You can use one color for all the warp threads and another for all the weft threads, or you can set up a
sequence of colors for each.
When defining thread color sequences using the pattern expression language, you must identify the colors
alphabetically. Therefore, you are limited to 26 colors of thread in the weaving.
Using the warp and weft color panels, you can create expressions that describe the color sequences that
you want. You can also use any letters that you like and then change the associated color later by modifying
the color set. For more information, see “To edit weave colors” on page 759.
The following table includes an example of a simple color sequence expressed in the Corel Painter pattern
language.
