PdfTilingPatternIsColored Property

(Required) A value that determines how the color of the pattern cell shall be specified:

• for Colored tiling pattern. The pattern’s content stream shall specify the colors used to paint the pattern cell. When the content stream begins execution, the current color is the one that was initially in effect in the pattern’s parent content stream. This is similar to the definition of the pattern matrix; see 8.7.2, "General Properties of Patterns".
• for Uncolored tiling pattern. The pattern’s content stream shall not specify any color information. Instead, the entire pattern cell is painted with a separately specified color each time the pattern is used. Essentially, the content stream describes a stencil through which the current color shall be poured. The content stream shall not invoke operators that specify colors or other color-related parameters in the graphics state; otherwise, an error occurs (see 8.6.8, "Color Operators"). The content stream may paint an image mask, however, since it does not specify any color information (see 8.9.6.2, "Stencil Masking").
