PPOCRLabel is a semi-automatic graphic annotation tool suitable for OCR field, with built-in PP-OCR model to automatically detect and re-recognize data. It is written in Python 3 and PyQT5, supporting rectangular box annotation and four-point annotation modes. Annotations can be directly used for the training of PP-OCR detection and recognition models.
bugs: 1.自动识别：报错闪退，例：demo/demo5.png 2.保存：在未使用自动标注的前提下，打开一张未被标记的图片，新建框后点击重新识别，识别完成后无法点击Save 3.单张图片模式下，双击文件列表或缩略图，文件和缩略图都会消失 optimizations: 缩略图：组件长度无法更改、前后图片按钮图标位置需要调整到正中间 缩略图：图片垂直居中
请针对这五部分着重测试。
