I have to write an application for image processing in python. does anyone know how to convert the file type of an image from JPEG to TIFF?

推荐答案

查看 Python图像库(PIL).参见教程，PIL易于使用.

Check out the Python Image Library (PIL). See this tutorial, the PIL is quite easy to use.

受支持的图像格式.

要进行转换，请打开图像，然后将其保存为新的扩展名(PIL使用该扩展名来确定用于保存的格式).

To do the conversion you open the image and then save it with the new extension (which PIL uses to determine what format to use for saving).

import Image
im = Image.open('test.jpg')
im.save('test.tiff')  # or 'test.tif'

请注意，官方发行版尚不支持Python 3.x(但?)，但是至少在Windows下存在

Note that the official distribution does not support Python 3.x (yet?), however, at least under Windows there's an unofficial version available that works with v 3.x.
