I will be working on a Photo Book app which will consist of some predefined templates where users can upload images from gallery or from Facebook Google Photos etc. here is a similar app https://play.google.com/store/apps/details?id=me.storytree.simpleprints&hl=en
I am not sure since ionic is just web app can handle this type of image manipulation, mostly it will be cropping and uploading to amazon S3 please suggest is there any library to work with images for ionic.
