Create a multiframe .tif file


I have pixel data that I want to use to create a new .tif image that has multiple frames. How would I go about doing this? I have tried python PIL however I have only found it supports multiple frame reading not writing. See below for my attempt that didn't work.

new_Image = Image.new("I;16", (num_pixels,num_rows))

for frame in range((len(final_rows)/num_rows)):
    pixels = new_Image.load()
    for row in range(num_rows):
        row_pixel = final_rows[row].getPixels()
        for pixel in range(num_pixels):
            pixels[pixel,row] = row_pixel[pixel]
    print frame
    new_Image.seek(frame)

Solution

  • For example, using numpy and scikit-image with FreeImage plugin:

    import numpy as np
    from skimage.io._plugins import freeimage_plugin as fi
    image = np.zeros((32, 256, 256), 'uint16')
    fi.write_multipage(image, 'multipage.tif')
    

    Or save it uncompressed using numpy and tifffile.py:

    import numpy as np
    from tifffile import imsave
    image = np.zeros((32, 256, 256), 'uint16')
    imsave('multipage.tif', image)
    

    This assumes that all pages have the same data shape and type and no additional tags need to be written.
