colour_hdri.NodeReadImage

class colour_hdri.NodeReadImage(*args: Any, **kwargs: Any)

Read the image from input path and return its data and metadata. The decoding CCTF of the input colourspace is used to linearise the image if it is stored using non-linear file format.

Methods

• __init__()

• process()

Return a new instance of the colour.utilities.TreeNode class.

Parameters:

• args (Any) – Arguments.

• kwargs (Any) – Keywords arguments.

__init__(*args: Any, **kwargs: Any) → None

Parameters:

• args (Any)

• kwargs (Any)

Return type:

None
