使用PIL/枕头将tiff(I; 16)转换为JPG [英] Convert tiff (I;16) to JPG with PIL/pillow

问题描述

将tiff图像从显微镜转换为jpeg时出现问题，应该在网络应用程序中显示该图像. 我尝试了以下方法:

I have a problem converting a tiff image from a microscope to a jpeg, which should be shown within a web application. I tried the following:

image = Image.open(file_name)
image.convert(mode="RGB")
image.save('my.jpeg')

>>IOError: cannot write mode I;16 as JPEG

任何人都具有将16位TIFF文件转换为jpegs的经验. 我已经在下面链接了这样的文件. 感谢您的帮助！

推荐答案

它是错误或在PIL/Pillow中未实现.这是一种解决方法:

It's either a bug or unimplemented in PIL/Pillow. Here is a workaround:

import Image
image = Image.open("Fredy1_002.tif")
image.mode = 'I'
image.point(lambda i:i*(1./256)).convert('L').save('my.jpeg')
