A pattern can be of any size and either monochrome, defined with only one bit per pixel, or colored. For details see:

Monochrome patterns are handled by the IlvPattern class. Two constructors are provided that you can use depending on the data available:

The first constructor initializes a new IlvPattern object with a pattern w pixels wide and h pixels high, filled in by the data stored in the data array of bit values. The pixel values are packed into 16-bit words from left to right in a most-significant-bits-first manner, and each scan line, stored from top to bottom, must be padded to 16 bits.

The second constructor initializes a new IlvPattern object from the given bitmap monochrome image.

To obtain a previously defined pattern, use the member function IlvDisplay::getPattern.

Other patterns are predefined within Rogue Wave® Views, which you can access by name.

Patterns can also be colored and are represented by instances of the IlvColorPattern class.
