colour.write_image

colour.write_image(image, path, bit_depth='float32', method='OpenImageIO', **kwargs)[source]

Writes given image at given path using given method.

Parameters

  • image (array_like) – Image data.

  • path (unicode) – Image path.

  • bit_depth (unicode, optional) – {‘float32’, ‘uint8’, ‘uint16’, ‘float16’}, Bit depth to write the image at, for the Imageio method, the image data is converted with colour.io.convert_bit_depth() definition prior to writing the image.

  • method (unicode, optional) – {‘OpenImageIO’, ‘Imageio’}, Write method, i.e. the image library used for writing images.

Other Parameters

attributes (array_like, optional) – {colour.io.write_image_OpenImageIO()}, An array of colour.io.ImageAttribute_Specification class instances used to set attributes of the image.

Returns

Definition success.

Return type

bool

Notes

  • If the given method is OpenImageIO but the library is not available writing will be performed by Imageio.

  • If the given method is Imageio, kwargs is passed directly to the wrapped definition.

Examples

Basic image writing:

>>> import os
>>> import colour
>>> path = os.path.join(colour.__path__[0], 'io', 'tests', 'resources',
...                     'CMS_Test_Pattern.exr')
>>> image = read_image(path)  
>>> path = os.path.join(colour.__path__[0], 'io', 'tests', 'resources',
...                     'CMSTestPattern.tif')
>>> write_image(image, path)  
True

Advanced image writing while setting attributes using OpenImageIO:

>>> compression = ImageAttribute_Specification('Compression', 'none')
>>> write_image(image, path, bit_depth='uint8', attributes=[compression])
... 
True
