1.针对元素截图后,只需要这张图片的部分内容。
2.需要裁剪
3.需要自己写一个库文件,当做自定义库文件来导入
4.实现
def resize_img(self,img1):
#打开指定的图片文件
image1 = Image.open(img1)
#获取图片的高和宽
(width,height) = image1.size
#重点来了,这里的宽取整张图片的3/4
w = image1.size[0]/4.0*3.0
#高维持不变,如果要变,根据自己需求来
h=image1.size[1]
#设置要裁剪的图片的左上角坐标(x,y)和右下角坐标(x+w, y+h)
x = 0
y = 0
region = image1.crop((x, y, x+w, y+h))
#保存到当前目录下,且名称为“车流量实际图.png”
region.save("./车流量实际图.png")
5.之前在网上找的一个是缩小图片的代码
#改变图片大小
def
resize_img(img_path):
try
:
img
=
Image.
open
(img_path)
(width,height)
=
img.size
new_width
=
200
new_height
=
height
*
new_width
/
width
out
=
img.resize((new_width,new_height),Image.ANTIALIAS)
ext
=
os.path.splitext(img_path)[
1
]
new_file_name
=
‘%s%s‘
%
(
‘small‘
,ext)
out.save(new_file_name,quality
=
95
)
except
Exception,e:
print
e
out
=
img.resize((new_width,new_height),Image.ANTIALIAS),这个里面的参数不对
