Detailed Description

Class representing an image of size width x height pixels.

Each pixel in the image is a Color object with red, green, blue components. There are functions for loading and saving the image in OpenEXR (.exr) format, and for getting and setting pixel values. This class is used as frame buffer in the raytracer, storing the output color of each pixel, and also used in the LightProbe class for representing the environment map.
