Input object for reading images from an OpenEXR file. The OpenEXR file format allows you to store high dynamic range images efficiently. It is recommended to use the load_* methods of MultiArray instead.
OpenEXR images allow storage of custom channels (red, green, blue, luminance, chroma-red, chroma-blue, z-buffer, alpha, ... ). HornetsEye does not provide access to z-buffer-, alpha-, and custom-channels. HornetsEye understands the following three cases:
- The image has a “Y” channel (luminance) but no “RY” and “BY” channel. In this case the image simply is a greyscale image.
- The image has a “Y”, “RY”, and a “BY” channel. In this case the image is converted to RGB using the OpenEXR library.
- The image has a “R”, “G”, and a “B” channel. In this case the image is a colour image.
Note that OpenEXR-support is optional and only available if installed properly (Frequently Asked Questions).
