我有一个使用spring boot和joinfaces的基本设置,以便在我的应用程序中使用primefaces和bootsfaces.
使用例如bootsfaces组件并执行ajax调用就像一个魅力.当我添加一个使用ajax的简单primefaces组件时,调用失败,我得到以下异常:

at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) …我的问题的背景如下.我有一个图片和一个裁剪矩形,描述了如何裁剪图片以生成结果图片.裁剪矩形总是较小或最大化图片的大小.现在应该可以旋转裁剪矩形.这意味着当在图片内旋转裁剪标记时,必须缩放裁剪,以使其延伸不超过照片.
Anybode可以帮我解决一个如何根据轴对齐的照片重新计算作物矩形的比例的公式吗？
我的第一次尝试是计算裁剪矩形的轴对齐边界框,而不是使其适合照片矩形.但不知何故,我陷入了这种方法,
编辑: 还有一点需要注意: - 裁剪矩形可以有其他尺寸,周围矩形内有另一个中心点.这意味着裁剪矩形可以小得多,但是例如位于图片矩形的左下边界.因此,当旋转较小的作物时,它也将超过其极限
在此先感谢塞巴斯蒂安
