Implement screen capture, save, open, and search.

Just an issue to track progress and ideas.

For the bitmap functions, I'll return an object similar to this:

MMBitmapRef createMMBitmap(uint8_t *buffer,
                           size_t width,
                           size_t height,
                           size_t bytewidth,
                           uint8_t bitsPerPixel,
                           uint8_t bytesPerPixel)
{
    MMBitmapRef bitmap = malloc(sizeof(MMBitmap));
    if (bitmap == NULL) return NULL;

    bitmap->imageBuffer = buffer;
    bitmap->width = width;
    bitmap->height = height;
    bitmap->bytewidth = bytewidth;
    bitmap->bitsPerPixel = bitsPerPixel;
    bitmap->bytesPerPixel = bytesPerPixel;

    return bitmap;
}

This way we can pass the necessary

With the new syntax this will go in the index.js.

function bitmap (imagedata, width, height) 
{
    this.imagedata = imagedata;
    this.width = width;
    this.height. = height;
}

bitmap.prototype.save = function(path) 
{
    robotjs.saveBitmap(this.imagedata, path);
};

module.exports.screen.capture = function()
{
    b = robotjs.captureScreen();
    return new bitmap(b.imagedata, b.width, b.height);
}

Then you'll use it like this:

var robot = require("robotjs");

var desktop = robot.screen.capture();

desktop.save("screencapture.png");

Note: I wrote this on my phone.

Might need to use:

createStringFromMMBitmap
createMMBitmapFromString

To pass the image between V8 and JavaScript.

This should be the next priority. Capture screen will allow for more projects to adopt RobotJS. (Also my mini project of a remote desktop )

Agreed, I would like to implement this since there's a special way I want it implemented (see bitmap branch). I'll start on this after #87 is merged and RobotJS is completely updated. This is going to take some extra work on Windows due to the libpng and zlib dependencies, which is the main reason I put it off. These libraries are required for disk related functionality, and createMMBitmapFromString.

#64 is another priority for me.
