How to write compressed tif

[mse...@gmail.com]

Hi,

I'm currently trying the imagio library for saving 16bit tiff images. Uncompressed (without using the meta data argument for writing) works fine. So how do I set the "compress" meta data?

I tried:
imageio.imwrite("D:\test.tif", ttt, format='TIFF', compress=9)
imageio.imwrite("D:\test.tif", ttt, format='TIFF', meta={'compress':9))

but I always get "TypeError: _open() got an unexpected keyword argument ..." I know I'm using the wrong call but I could not find any examples for using additional arguments for writing images

Thanks for your help,

Matthias

Hi Matthias,

 

The compression is indeed part of the meta data, but you cannot set that using imread. Try this:

 

with Imageio.get_writer(r‘D:\test.tif’) as w:

    w.append_data(ttt, {‘compress’: 9})

 

Regards,

  Almar
