Exporting a screen capture image bigger than native screen resolution?

I’m building up a canvas made of 1000s of images using ofImage and ofFbo, then I am exporting the final image using grabScreen and saveImage.

I’d like to export it as a 6 megapixel jpg or something similar, however my screen resolution is much lower than that, so the export only ever comes out at my screen size…

Is there any way to get around this?


I haven’t used it but I do remember hearing about this addon
