I'm trying to export a 24k image (export set to 1650DPI) using the "export as image" function but I keep getting the "Could not allocate required memory for image" warning.
I don't understand why this is happening as I am running 64bit and have 64gb of RAM installed.
Exporting at a slightly lower DPI of 1400 works and produces a file that is only 50mb. I've checked resource usage and I don't even break the 32gb mark so how can QGIS be running out of memory!?
