I wrote a paint.net plugin that generates hexadecimal strings from a colored image.
The plugin is made so easy to use for speeding up sprite management in order to get to coding !
1. So to use it first you will have to install the free software Paint.net (if you dont have it already)
getpaint.net.
2. Next you will need to download my plugin (its called in effect in paint.net but i used it differently).
https://drive.google.com/open?id=0BwL8OxR4bj83NFlIaFFpNHJSWUk&authuser=03. Put this file in the folder Paint.NET/Effects/
4. Startup Paint.NET, open up an image, select it with CTRL+A, click on EFFECTS, click PNGtoHEX which should be at the bottom.
You will get a popup like this
Select it and click CTRL+C to copy it
After copying it there will be some extra dashes in the beginning and the end of your clipboard just delete those, i am not sure how to remove them since they come with the default messagebox stuff...
Anyways! thats all i hope you find this useful, if you have any feature suggestions i will for sure implement.
