python实现多图像叠置输出 python实现多图像叠置输出

本文实例为大家分享了python实现多图像叠置输出，供大家参考，具体内容如下
代码

from PIL import Imagedef add_alpha_channel(img): img = Image.open(img) img = img.convert('RGBA') # 更改图像透明度 # factor = 0.7 # img_blender = Image.new('RGBA', img.size, (0, 0, 0, 0)) # img = Image.blend(img_blender, img, factor) return imgdef image_together(image, layer1, layer2, save_path, save_name): layer1 = layer1 layer2 = layer2 base = image bands = list(layer1.split()) heigh, width = layer1.size for i in range(heigh):for j in range(width):r, g, b, a = layer1.getpixel((i, j))if r == 0:layer1.putpixel((i, j), (0, 0, 0, 0)) # 背景透明显示else:layer1.putpixel((i, j), (0, 0, 256, 200)) # 非背景区域显示为红色 layer2.paste(layer1, (0, 0), layer1) # 贴图操作 base = image bands = list(layer2.split()) heigh, width = layer2.size for i in range(heigh):for j in range(width):r, g, b, a = layer2.getpixel((i, j))if r == 0:layer2.putpixel((i, j), (0, 0, 0, 0))elif r == 128 and g == 128 and b == 128:layer2.putpixel((i, j), (128, 128, 128, 200))else:layer2.putpixel((i, j), (255, 0, 0, 200)) base.paste(layer2, (0, 0), layer2) # 贴图操作 base.save(save_path + "/" + save_name + ".png") # 图片保存if __name__ == "__main__": image = add_alpha_channel(r"") layer1 = add_alpha_channel(r"") layer2 = add_alpha_channel(r"") image_together(image, layer1, layer2, r"", "")
