问题描述
我想要实现的是...我在textpane中有一个文本，我将其转换为BufferedImage并通过使用鼠标拖动来调整图像大小.现在，如果要编辑文本，请单击该图像，该图像将隐藏该图像并显示来自文本窗格的文本.
What I am trying to achieve is that... I have a text in textpane which I am converting to BufferedImage and resizing the size of the image by dragging it with mouse. Now If I want to edit the text, I am clicking on the image which hides the image and shows the text from textpane.
我的问题是文本窗格中文本的大小没有调整大小(增加/减小)，因为调整大小是在图像而不是文本上进行的.那么，当我调整包含文本的图像的大小时，如何更改字体大小?
My problem is the size of the text in textpane is not resized(increased/decreased) as resize was done on image and not on text. So how do I change the font size as and when I resize the image containg text?
推荐答案
您可以通过使用AffineTransform派生基本字体来调整字体大小.基本上，您将需要维护对用户开始使用的基本字体的引用.必要时，您可以通过以适当的比例提供AffineTransform来派生新的字体实例，并将其应用于文本窗格
You can adjust the font size by deriving the base font with a AffineTransform. Basically, you will need to maintain a reference to the base font that the user started with. When you need to, you would derive a new font instance by suppling a AffineTransform with the appropriate scale and apply that to the text pane
