Clone from my github

git clone https://github.com/tingruikp0925/simpleocr.git

After you upload the picture for this sample
You can Read/Resize/Flip/Rotate or cvtColor via use cv2 package.

Follow this information and change the config you need.

Read：cv2.imread(filename, flags)
Show：cv2.imshow(window_name, image)
Save：cv2.imwrite(save_filename, image)
Resize：cv2.resize(image, size, interpolation)
Flip：cv2.flip(image, flipCode)
Rotate： M = cv2.getRotationMatrix2D(rotate_center, rotate_angle, ratio) rot_img = cv2.warpAffine(image, M, size)
CvtGray: cv2.cvtColor(image, colorspace_num=7)
