How to get an exr's image's Full/display size format from reader?


I have an exr sequence that only has information in the center of the image so
readnode.getRegionOfDefinition(0, 0).height()
readnode.getRegionOfDefinition(0, 0).width()
returns only the bound of the content NOT the image resolution.

readnode.getParam(“nodeInfos”).get() returns and unreadable string to parse

I’ve searched the help and couldn’t find any solutions, is there not a simple .getFormat() function?
