一、分析问题背景 java.awt.geom.NoninvertibleTransformException是Java2D图形处理中常见的异常之一，通常在尝试获取AffineTransform对象的逆变换时抛出...AffineTransform是Java2D中用于进行几何变换的类，它支持缩放、旋转、平移和错切等操作。...场景示例： AffineTransform transform = new AffineTransform(); // 设置缩放因子为0 transform.scale(0, 1); try {...// 尝试获取逆变换 AffineTransform inverse = transform.createInverse(); } catch (NoninvertibleTransformException...下面是一个正确的代码示例： public void applyTransform(Graphics2D g2d) { AffineTransform transform = new AffineTransform
首先创建AffineTransform对象，然后调用setTransform()方法设置transform属性。最后，用具有指定属性的Graphics2D对象绘制图形。...创建AffineTransform对象的方法有： getRotateinstrance(double theta)：旋转theta弧度。...也可以先创建一个没有transform属性的AffineTransform对象，然后用以下方法指定图形平移、旋转、缩放变换属性。...例如，创建AffineTransform对象： AffineTransform trans = new AffineTransform(); 为AffineTransform对象指定绕点旋转变换属性
