<基本的过程是创建一个文本的轮廓，并呈现它...容易;）
这使用 TextLayout class来生成一个 Shape 的文本，可以填充和绘制。 =https://i.stack.imgur.com/76d1s.pngalt =在这里输入图片描述>

Is there any way that I could assign a specific image to a String so that the output would be something like this (im using the String with a JLabel):
解决方案
The basic process is to create an outline of the text and render it...easy ;)
This uses the TextLayout class to generate a Shape of the text, which can filled and drawn.
