【備忘】cv2.rectangle TypeError

img = cv.rectangle( img, pt1, pt2, color[, thickness[, lineType[, shift]]] )
img = cv.rectangle( img, rec, color[, thickness[, lineType[, shift]]] )

問題

• {TypeError}an integer is required (got type tuple)
• {TypeError}argument for rectangle() given by name (‘color’) and position (3)
• {TypeError}argument for rectangle() given by name (‘thickness’) and position (4)
• {TypeError}an integer is required (got type tuple)

解決辦法

• 座標pt1,pt2需要是整型
• img=np.ascontiguousarray(img)，然後調用rectangle
