Class TTFMarkFactory

Object

TTFMarkFactory

All Implemented Interfaces:

MarkFactory

public class TTFMarkFactory
extends Object
implements MarkFactory

This factory accepts mark paths in the ttf://fontName#code format, where fontName is the name of a TrueType font installed in the system, or a URL to a TTF file, and the code is the character code, which may be expressed in decimal, hexadecimal (e.g. 0x10) octal (e.g. 045) form, as well as Unicode codes (e.g. U+F054 or  ).

getShape

public Shape getShape(Graphics2D graphics,
                      Expression symbolUrl,
                      Feature feature)
               throws Exception

Description copied from interface: MarkFactory

Turns the specified URL into an Shape, eventually using the Feature attributes to evaluate the expression, or returns null if the factory cannot evaluate this symbolUrl.

The returned Shape must not exceed the [-0.5, -0.5, 0.5, 0.5] bounds (will be rescaled according to the parameter given in graphics on the fly

Specified by:

getShape in interface MarkFactory

symbolUrl - the expression that will return the symbol name. Once evaluated the expression should return something like plainName or like protocol://path. See the actual implementations for details on the kind of supported name.

feature - The feature that will be used to evaluate the symbolURL expression (or to extract data from it, think complex attributes, in that case a visit to the expression and some direct attribute value extraction might be needed instead)

Throws:

Exception

getShape

public Shape getShape(ExternalMark mark)

Returns a shape from an external mark definition
