Blitline vs CImg: What are the differences?

Developers describe Blitline as "Image processing in the cloud (cropping, rotating, compositing, filtering)". Blitline drastically reduces the amount of work you need to develop an application that does any image processing. Stop rebuilding the same image processing functionality, let us do it for much less than it would cost you to make and support it. Pay for only the image processing time that your jobs use. We believe your images should be YOUR images. We also believe that you should never be "locked in" to using Blitline. The flexibility of the JSON API means you could stub out Blitline later without ever touching your production/deployed code. On the other hand, CImg is detailed as "A small and open-source C++ toolkit for image processing". It mainly consists in a (big) single header file CImg.h providing a set of C++ classes and functions that can be used in your own sources, to load/save, manage/process and display generic images.

Blitline and CImg can be categorized as "Image Processing and Management" tools.

CImg is an open source tool with 701 GitHub stars and 163 GitHub forks. Here's a link to CImg's open source repository on GitHub.
