JavaFX Canvas字体都是一样的

Question

我试图写入JavaFX画布。我在混合字体方面遇到了问题。我使用黑色和白色。

    Font currentFont = new Font("Georgia",125);
    FontMetrics metrics = Toolkit.getToolkit().getFontLoader().getFontMetrics(currentFont);
    canvas.getGraphicsContext2D().setFont(currentFont);
    float charWidth = metrics.computeStringWidth(jString);
    canvas.getGraphicsContext2D().fillText(jString, 1, 100, charWidth);
    float charWidthSum = charWidth;

    canvas.getGraphicsContext2D().setFont(new Font("Carlito",60));
    metrics = Toolkit.getToolkit().getFontLoader().getFontMetrics(new Font("Carlito",60));
    charWidth = metrics.computeStringWidth(aString);
    canvas.getGraphicsContext2D().fillText(aString, charWidthSum, 100, charWidth);
    charWidthSum+=charWidth;

    canvas.getGraphicsContext2D().setFont(new Font("Ariel",50));
    metrics = Toolkit.getToolkit().getFontLoader().getFontMetrics(new Font("Ariel",50));
    charWidth = metrics.computeStringWidth(vString);
    canvas.getGraphicsContext2D().fillText(vString, charWidthSum,100, charWidth);
    charWidthSum+=charWidth;

    canvas.getGraphicsContext2D().setFont(new Font("Times",125));
    metrics = Toolkit.getToolkit().getFontLoader().getFontMetrics(new Font("Times",125));
    charWidth = metrics.computeStringWidth(a2String);
    canvas.getGraphicsContext2D().fillText(a2String, charWidthSum, 100, charWidth);


    //HOW TO IMPLEMENT - to collect the content of a string, keeping font type the same
    /*
        public void setPixels(int x, int y, int w, int h,
                      PixelFormat<ByteBuffer> pixelformat,
                      byte buffer[], int offset, int scanlineStride);
     */
    ByteBuffer byteBuffer = null;
    byte[] bytes = new byte[0];
    PixelFormat<ByteBuffer> pixelFormat = null;
    canvas.getGraphicsContext2D().getPixelWriter().setPixels(0,0,0,0,null,bytes, 0,0); //write my new character
    // 

将是相同的字体，因为我假设我只是设置当前可写字体。如果您看到未实现的部分，我正在考虑尝试使用像素编写器来编写字体。如何让他们进入正确的形式？我使用黑色单调字体

另外，我了解TextFlow和StyledTextArea。 StyledTextArea用于相同的高度文本，TextFlow不能写入画布，只能写入节点。我认为我需要画布功能。
