Interface SVGPath

public interface SVGPath

This interface represents an "SVGPath" datatype used to define the path geometry. Corresponds to SVG path specification or the "d" attribute.

The native implementations must support the following simplifications or canonicalization of path segments. Any simplifications should be lossless.

• Relative commands (c, h, l, m, q, s, t, and v) must be converted to their absolute counterparts·
• Horizontal and Vertical lines (H, h, V, and v) must be converted to general lines (L and l)·
• Translate command S to command C·
• Translate command T to command Q.

BlackBerry API 4.6.0
