jlatexmathfx is a port of jlatexmath to javafx
The control is usable but not thoroughly tested.
The performance has not been optimized but is acceptable on local tests. Upon first use initialization will happen but subsequent calls will be faster.
0.3.3
The project uses maven as build tool. To generate the jar use:
maven package
LatexMathControl is a styleable javafx control.
The following properties control the visulaization
Property | Default | CSS Property Purpose | |
---|---|---|---|
formula | "" | fx-formula | The laTeX encoded formula |
size | Default javafx font size | fx-size | Font scaling, default is equal to the javafx default size |
bgColor | Color.Transparant | fx-bg | Background Color |
textColor | Color.BLACK | fx-text-color | fill color of the Font |
This example has been adapted from the origial swing based distribution. The code produces the following output
public class FXApp extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
String latex = "\\begin{array}{l}";
latex += "\\forall\\varepsilon\\in\\mathbb{R}_+^*\\ \\exists\\eta>0\\ |x-x_0|\\leq\\eta\\Longrightarrow|f(x)-f(x_0)|\\leq\\varepsilon\\\\";
