There are some interesting aspects of text rendering with which you should familiarize yourself
before you leave this recipe.
Text origin
Unlike other node types, the text node has a variable coordinate system which can be
changed dynamically to accommodate where the text is rendered relative to its
y
coordinate
using the
textOrigin:TextOrigin
property. The following code snippet shows how this
works. You can get the full list in
ch02/source-code/src/text/TextOriginDemo.fx
.
Line{startX:50 startY:0 endX:50 endY:200 stroke:Color.SILVER}
Line{startX:0 startY:25 endX:400 endY:25 stroke:Color.SILVER}
Text {
x:50 y: 25
font: Font {size: 20 name:"Arial Black"}
fill:Color.BROWN
textOrigin: TextOrigin.TOP
content: "This text uses TextOrigin.TOP"
}
The
TextOrigin
class includes the following options:
F
TextOrigin.BASELINE
—with this option (default), the coordinate system for the
text originates from the bottom left-hand corner of the bounding box for the first line
of the text. The bottom of all non-descending letters are drawn along the
y
coordinate
as shown in the previous figure.
F
TextOrigin.TOP
—the reference coordinate for the text originates from the upper
left-hand corner of the bounding box of the text, rendering the tallest letter of the first
line below the
y
coordinate as shown in the previous figure.
