详情

在使用PPOCRLabel工具进行矩形标注时弹出的错误，PPOCRLabel为标注ocr数据集的工具。

bug 详细输出

Traceback (most recent call last):
File "xxx\lib\site-packages\PPOCRLabel\libs\canvas.py", line 596, in paintEvent
	p.drawRect(leftTop.x(), leftTop.y(), rectWidth, rectHeight)
TypeError: arguments did not match any overloaded call:
drawRect(self, rect: QRectF): argument 1 has unexpected type 'float'
drawRect(self, x: int, y: int, w: int, h: int): argument 1 has unexpected type 'float'
drawRect(self, r: QRect): argument 1 has unexpected type 'float'

原因：从输出可以发现，这是由于drawRect函数的输入坐标为float 类型引发的错误。

实际上，drawRect函数的输入坐标应该为整型int。

解决方法

找到出现bug的canvas.py中paintEvent函数的 p.drawRect(leftTop.x(), leftTop.y(), rectWidth, rectHeight)

将里面坐标值强制转为int：

p.drawRect(int(leftTop.x()), int(leftTop.y()), int(rectWidth), int(rectHeight))
