1、图片尺寸修改from PIL import Imagedef resizeImage(image_in, image_out): """ 修改jpg 图片尺寸到 200kb 左右 """ width = 1600 img = Image.open(image_in) w, h = img.size # print(w, h) height = 1600 * h // w # print(height) out = img.resize((width, height), Image.ANTIALIAS) # resize image with high-quality out.save(image_out)def test1(): import ocr rpa.win32.win_activate("金蝶") sleep(2) x1, y1 = rpa.win32.pos("应收单底部金额1_img") x2, y2 = rpa.win32.pos("应收单底部金额2_img") img_in = r"D:\img_in.png" img_out = r"D:\img_out.png" import pyautogui pyautogui.FAILSAFE = False pyautogui.screenshot(imageFilename=img_in, region=(x1, y1, int(x2) - int(x1), int(y2) - int(y1))) resizeImage(img_in, img_out) #默认aliyun ocr获取结果，access_key_id及access_key_secret替换成自己的 text = ocr.text(img_out, app_code='129fe845778e40a69fdf84c09b601be8')2、图片二值话，把有颜色的图片变成黑白图片
from PIL import Imagedef convert_Binary_image(filepath, newfilepath): # 自定义灰度界限，大于这个值为黑色，小于这个值为白色 threshold = 200 img = Image.open(filepath) # 灰度化 img_gray = img.convert("L") img_binary = img_gray.point(lambda x: 0 if x < threshold else 255) img_binary.show() img_binary.save(newfilepath) return img_binaryconvert_Binary_image(r"D:\img_in.png", r"D:\imag_in.png")
