How to save image as binary compressed .tiff python?

Question

Is there any library to save images in binary (1bit per pixel) .tiff compressed file? opencv and pillow cannot do that

do you find any solution for your problem ? – beesleep Sep 01 '19 at 11:26 — beesleep, Sep 01 '19 at 11:26
@beesleep I haven't found a solution so far – asmekal Sep 03 '19 at 17:03 — asmekal, Sep 03 '19 at 17:03

In fact, I just found a way to do it with Pillow, but some tweaks are needed because of some bug.

import numpy as np
from PIL import Image, TiffImagePlugin

filepath = '/some/file/path.tif'
# generate a 1bit image
ar = np.random.rand(50, 50) > 0.5
arr_2 = np.repeat(np.repeat(ar, 10, axis=0), 10, axis=1)

# save it t
size = mask.shape[::-1]
databytes = np.packbits(mask, axis=1)
mask = Image.frombytes(mode='1', size=size, data=databytes)
TiffImagePlugin.WRITE_LIBTIFF = True
mask.save(filepath, compression='packbits')
TiffImagePlugin.WRITE_LIBTIFF = False

You can try using libtiff.

Install using pip install libtiff

can you provide exact way to save? something like `libtiff.save_image(fname, format='rle')` - I am unsure if it's possible with this library – asmekal Dec 11 '18 at 18:13
