      Description

      A client submitted an interesting file that contains 15 images that are 12848 x 27733 in size. The images also need to be converted to RGB which adds additional overhead.

      This file cannot be loaded on a conventional machine as it needs more then 32GB of memory to load all the images. There are optimization we we could make to our rendering pipeline to improve our memory foot print. The first method is to render the image using smaller tiles that we can paint to the a small canvas size. Computationally expensive but can be setup to use a lot less memory. I believe this is also known as sub sampling.
