ImageGeneratorBuilder class

Builds a pipeline of image generator middleware.

The pipeline is composed by calling use one or more times, then calling build to produce the final ImageGenerator. Middleware factories are applied in reverse order so that the first call to use produces the outermost wrapper.

This is an experimental feature.
