How can I create a raster from a custom Pixel array?

(Copied from stackoverflow to get extra help: java - How can I create a raster from a custom Pixel array? - Game Development Stack Exchange)

I have a rasterizer that I am building. It will first load a .obj file and create points to draw. Then, an image will be plastered over the wire frame and from there become an image on the next frame. The details are:

Load vectors from file







create a wire frame from the points







overlay an image







create raster from Pixel[] array







create BufferedImage







draw to screen







The last three steps repeat after loading the vectors.

My Pixel class just stores an RGB value, as well as I have an RGB class which specifies how much Red, Green, and Blue. (public Pixel(RGB rgb))

With an array of these Pixels, I want to make a Raster. How can I create a Raster with raw pixel data? the colors are 64-bit if that helps (private static final long RED, GREEN, BLUE; in RGB instance within Pixel instance)
