python图像库保存功能 [英] python imaging library save function

问题描述

我刚刚使用python图像库(PIL)完成了一些图像处理，但无法使save函数正常工作.整个代码工作正常，但不会保存生成的图像.代码如下:

I have just done some image processing using the python image library (PIL) and I can't get the save function to work. the whole code works fine but it just wont save the resulting image. The code is below:

im=Image.new("rgb",(200,10),"#ddd")
draw=Image.draw.draw(im)
draw.text((10,10),"run away",fill="red")
im.save("g.jpeg")

保存时会出现错误，因为扩展名未知，甚至删除点也无济于事.

Saving gives an error as unknown extension and even removing the dot doesn't help.

推荐答案

使用.jpg:

im.save("g.jpg")

图像库确定扩展名要使用哪种编码器，但是在某些版本的PIL中，JPEG编码器不注册.jpeg扩展名，而仅注册.jpg.

The image library determines what encoder to use by the extension, but in certain versions of PIL the JPEG encoder do not register the .jpeg extension, only .jpg.

另一种可能性是您的PIL安装根本不支持JPEG ；例如，尝试将图像另存为PNG.

Another possibility is that your PIL installation doesn't support JPEG at all; try saving the image as a PNG, for example.
