from PIL import Image
1.打开图片
img = Image.open(fileName)
2.保存图片
img.save(imgName)
3.调整图片大小
def resize(self, width, height):
o_width, o_height = img.size
o_ratio = o_width/float(o_height)
n_ratio = width/float(height)
if o_ratio > n_ratio:
re_ration = width/float(o_width)
a_height = int(re_ration*o_height)
img = self.img.resize((width,a_height),Image.ANTIALIAS)
else:
re_ration = height/float(o_height)
a_width = int(re_ration*o_width)
img = img.resize( (a_width,height),Image.ANTIALIAS)
img.save(‘test.jpg‘)
4.新建图片
img = Image.new("RGB", (width, height), "black")
5.粘贴拷
box = (100,100,500,500)#设置要拷贝的区域
region = im.crop(box)
region = region.transpose(Image.ROTATE_180)#从字面上就可以看出,先把region中的Image反转180度,然后再放回到region中。
im.paste(region, box)#粘贴box大小的region到原先的图片对象中。
