Field Detail

DEFAULT

static final Displacement DEFAULT

Default Displacement instance.

NULL

static final Displacement NULL

Null Displacement instance.

Method Detail

getDisplacementX

Expression getDisplacementX()

Returns an expression that computes a pixel offset from the geometry point. This offset point is where the text's anchor point gets located. If this expression is null, the default offset of zero is used.

Specified by:

getDisplacementX in interface Displacement

Returns:

Horizontal offeset

setDisplacementX

void setDisplacementX(Expression x)

Sets the expression that computes a pixel offset from the geometry point.

setDisplacementY

void setDisplacementY(Expression y)

Sets the expression that computes a pixel offset from the geometry point.

accept

void accept(StyleVisitor visitor)
