Hello, Being relatively new to the OpenEXR format, I have a couple of questions regarding multi-layer EXR:
1) What is the (optimal) way to go if I want to merge/compose all the layers of an EXR (say flat image for simplicity) into a single layer (RGBA-only channels), so that I can convert it to another format and rescale it as needed for quick viewing ? -- just like viewing thumbnails, but probably at a higher resolution. I understand that I have to manually determine what the layers are and their respective channels, but I don't know (especially) the order in which to merge them. NOTE: I use the terminology "flat image" to refer to non-deep images (since "flattening" is used by OIIO to denote this operation) and "merge"/"compose" for rendering multi-layers into a single layer; but other SW use "flattening" to refer to the merge/compose operation. 2) How do I treat "special" channels like effects, vectors etc. in the scenario at point 1? 3) Does using the `flatten()` function for deep and multi-layer images (EXRs) also merge the layers or not? I assume not, but I cannot verify this, since I don't have an EXR sample. I would greatly appreciate if someone has a sample like this. Thank you, Radu Arjocu<http://www.masstech.com>
