Read and write imagesΒΆ

This example shows how to read and write images in various file formats:

def read_and_write_image():
        Demonstrates reading and writing images.

        # .tif image
        img1 ='t1-head.tif'))

        # .png image
        img2 ='uint8.png'))

        # .raw file
        img3 ='t1-head_bin_'))

        # Save sequence. The @(3) declares that the file name should contain 3 numeric digits in the place of @, e.g. head_001_bin.tif.
        pi.writesequence(img3, output_file('binary_head/head_@(3)_bin.tif'))

        # Read sequence back. Notice that reading does not support (3) directive in the sequence template!
        img4 ='binary_head/head_@_bin.tif'))

        # Images can also be read into existing images.'binary_head/head_@_bin.tif'), target_image=img1)

        # When saving .raw files, the dimensions are appended to the file name
        pi.writeraw(img2, output_file('uint8_as_raw'))

        # When reading .raw files, it is not necessary to give the dimensions and .raw suffix
        # if the given part of the file name identifies an unique .raw file
        img2 ='uint8_as_raw'))
