python图片处理

设置图片像素

from PIL import Image

def set_image(path, width=280):
    """设置图片像素"""
    # 打开图片
    image = Image.open(path)

    # 原来大小
    original_width, original_height = image.size
    # 设置新的图片大小
    new_width, new_height = width, int(original_height * width / original_width)  # 举例，设置新的宽度和高度约为280x200
    resized_image = image.resize((new_width, new_height))

    # 保存新的图片
    resized_image.save(path)

滑动图片验证

import ddddocr

def generate_distance(slice_image, bg_image):
    """滑动图片验证
    :param bg_image: 背景图字节
    :param slice_image: 滑块图字节
    :return: distance
    :rtype: Integer
    """
    slide = ddddocr.DdddOcr(det=False, ocr=False, show_ad=False)
    # slice_image = slice_url  # requests.get(slice_url).content
    # bg_image = bg_url  # requests.get(bg_url).content
    result = slide.slide_match(slice_image, bg_image, simple_target=True)
    # print(result)
    return result['target'][0]  # target 输出左上角和右下角的坐标

裁剪图片

from PIL import Image

# 裁剪前景图片
img = Image.open("qg.png")
print("前景原图大小：", img.size)
cropped = img.crop((58, 207, 58 + 50, 207 + 50))  # (left, upper, right, lower)
cropped.save("qg.png")
