我们称它为"catch".

We call it ''catch''.

按无穷大缩放图形上下文是没有意义的.您可能应该再看一遍代码，看看为什么要创建该值，如果它确实有效，则图形绘制部分应该做一些不同的事情(限制比例尺或不绘制任何内容).在这种情况下抛出异常是绝对正确的.

Scaling a graphics context by infinity makes no sense. You should probably have a look at the code a bit further up and see why that value is being created, and if it is actually valid, your graphics drawing section should do something different (cap the scale or not draw anything). It is absolutely correct to throw an exception in that case.
