# Screenshot tool
This is just a simple plugin that takes screenshot of the TV and DRC screen. The screenshot will saved on the sd card.
## Wii U Plugin System
This is a plugin for the [Wii U Plugin System (WUPS)](https://github.com/Maschell/WiiUPluginSystem/). To be able to use this plugin you have to place the resulting `.mod` file into the following folder:
```
sd:/wiiu/plugins
```
When the file is placed on the SDCard you can load it with [plugin loader](https://github.com/Maschell/WiiUPluginSystem/).
## Building
For building you need:
- [wups](https://github.com/Maschell/WiiUPluginSystem)
- [dynamic_libs](https://github.com/Maschell/dynamic_libs/tree/lib) for access to the functions.
- [libutils](https://github.com/Maschell/libutils) for common functions.
Install them (in this order) according to their README's. Don't forget the dependencies of the libs itself.
Other external libraries are already located in the `libs` folder.
- libjpeg
- libturbojpeg

* The RGB_RED, RGB_GREEN, RGB_BLUE, and RGB_PIXELSIZE macros are a vestigial

* to compress from/decompress to a BGR/BGRX/RGBX/XBGR/XRGB buffer, they could
* change these macros, rebuild libjpeg, and link their application statically

* severe restrictions involved (cjpeg and djpeg no longer worked properly,
* compressing/decompressing RGB JPEGs no longer worked properly, and the color
* quantizer wouldn't work with pixel sizes other than 3.) Further, since all
* of the O/S-supplied versions of libjpeg were built with the default values
* of RGB_RED, RGB_GREEN, RGB_BLUE, and RGB_PIXELSIZE, many applications have
* come to regard these values as immutable.
*
* The libjpeg-turbo colorspace extensions provide a much cleaner way of
* compressing from/decompressing to buffers with arbitrary component orders
* and pixel sizes. Thus, we do not support changing the values of RGB_RED,
* RGB_GREEN, RGB_BLUE, or RGB_PIXELSIZE. In addition to the restrictions
