Useful when implementing a design, to make the design pixel accurate.
I’ve used the pixel perfect plugin for firefox to do this, but it doesn’t seem to work anymore. The best would be a separate program that can be used independently of browser. Any recommendations?
I’m working on a javascript tool for developers to manage image overlays: https://github.com/frontfoot/overlay_me
I found another solution though that is corresponding to your need: http://makiapp.com/
My version of the tool is a bit more developer oriented, as you can have a pack of overlaying images loading automatically per project, and also keeping the possibility to inspect DOM elements while overlaying things.
The makiapp tool is a more accessible, designer oriented, where you can upload a local file.
My tool is at its first stage and need feedback BTW 😉
