Custom user mask

Jungfraujoch allows to upload custom user mask. This happens in two steps. First create mask in TIFF format:

import numpy as np
import tifffile as tiff

# Create a 2068x2164 numpy array filled with zeros, with 32-bit unsigned integers
array = np.zeros((2068, 2164), dtype=np.uint32)

# Mark the pixel (300, 400) with the value 1
array[300, 400] = 1

# Save the array as a TIFF file
tiff.imwrite('mask.tiff', array)

Pixels with non-zero value in the TIFF file will be marked as belonging to the user mask.

Then upload the mask to Jungfraujoch server:

curl -v http://<jfjoch_broker http address>/config/user_mask.tiff -XPUT --data-binary @mask.tiff
