+ *

+ * + * User-defined Line Patterns + *

+ * A user-defined line pattern is specified with a pattern mask and + * an optional scale factor. + *

+ * The Pattern Mask

+ * + * The pattern is specified + * using a 16-bit mask that specifies on and off segments. Bit 0 in + * the pattern mask corresponds to the first pixel of the line or line + * strip primitive. A value of 1 for a bit in the pattern mask indicates + * that the corresponding pixel is drawn, while a value of 0 + * indicates that the corresponding pixel is not drawn. After all 16 bits + * in the pattern are used, the pattern is repeated. + *

+ * For example, a mask of 0x00ff defines a dashed line with a repeating + * pattern of 8 pixels on followed by 8 pixels off. A value of 0x0101 + * defines a a dotted line with a repeating pattern of 1 pixel on and 7 + * pixels off. + *

+ * The pattern continues around individual line segments of a line strip + * primitive. It is restarted at the beginning of each new line strip. + * For line array primitives, the pattern is restarted at the beginning + * of each line. + *

+ * The Scale Factor + *

+ * The pattern is multiplied by the scale factor such that each bit in + * the pattern mask corresponds to that many consecutive pixels. + * For example, a scale factor of 3 applied to a pattern mask of 0x001f + * would produce a repeating pattern of 15 pixels on followed by 33 + * pixels off. The valid range for this attribute is [1,15]. Values + * outside this range are clamped.
