Key & Default Value
Type
Mandatory
*
Description
*
textColor = default foreground color of the
* renderer
Color
no
*
The text color.
*
fontName = default font name of the
* renderer
String
no
*
The name of the text font. The standard Java font name
* "Serif", "SansSerif", and "Monospaced" can be used.
* Other font names depend on the actual {@link Renderer}
* rendering the corresponding {@link BasicGraphicalElement}.
*
*
fontStyle = normal
String
*
no
*
The font style. Possible values are:
*
normal
bold
italic
*
bold italic
*
*
fontSize = default font size of the
* renderer
double
no
*
The font size in units of the device-independent
* coordinates.
*
orientationAngle = 0
double
*
no
*
The orientation angle of the text (in degree).
* Zero means normal orientation whereas a positive value means
* a rotation in counter-clockweise direction.
*
horizontalAnchor = left
String
*
no
*
Anchor for horizontal text position. Possible values are
* left, center, and right.
*
verticalAnchor = center
String
*
no
*
Anchor for vertical text position. Possible values are
* top, center, and bottom.
*
* Additional configuration parameters are explained in the
* {@link ShapeAttributes#ShapeAttributes constructor}
* of the superclass {@link ShapeAttributes}.
