i working on project have users uploading print quality high resolution tif images , need create lower resolution web quality preview user if/when come view uploaded.
currently have working solution resize these images using imageio.read , imageio.write taking 15 minutes modify , save these preview images. wondering if there better solution take less time complete. or ram issue experiencing?
i'm not sure libraries you're using, can in 2 passes. if you're cutting resolution half in width , height, take every other pixel , create quick image that. low quality, should able on large images. later, perhaps workflow automation system, can "slow cook" better-quality derez , take time well.
