Import a really big raw image or process it without opening and displaying

I have a really big image I want to process in ImageJ. It is a 1-Bit RAW file spanning 116000x116000 pixels. When I try to import into ImageJ I get an error relating boundaries and the image does not open. I'm guessing this means it's too big to open and display.

Is there a way I can work on this image without actually displaying it? I have a macro where I do some fairly basic image operations on a small sub-section of it, but my macro currently requires that the image be opened once to draw a ROI on it.

Any tips are much appreciated.
