Description
/builddir/build/BUILD/materialx-1.39.5-build/BUILDROOT/usr/bin/oiio_loader: line 24: Sample MaterialX ImageLoader implementation using OpenImageIO package.
This module provides a MaterialX-compatible ImageLoader implementation using OpenImageIO (OIIO). The test will test loading an image, save it out, and optionally previewing it.
Steps
1. Create an OIIOLoader which is derived from the ImageLoader interface class. 2. Create a new ImageHandler and register the loader with it. 3. Request to acquire an image using the ImageHandler. An EXR image is requested. 4. OIIOLoader will return supported extensions and match the requested image format. 5. As such the OIIOLoader will be requested to load in the EXR image, convert the data and return a MaterialX Image. 6. Try to acquire the image again. This should returnt the cached MaterialX Image. 7. Save the image back to disk in the original format.
The image can optionally be previewed after load before save.
