Basics?

[TGE]

Someone ought to fix code formatting, lol.
C# code example:

Code:

public static Bitmap Create(Color[] palette, byte[] indices, int width, int height)
{
    Bitmap bitmap = new Bitmap(width, height, PixelFormat.Format32bppArgb);
    for (int y = 0; y < height; y++)
    {
           // we traverse through the image from top to bottom
        for (int x = 0; x < width; x++)
        {
                        // ..and from left to right
                        // x + (y * width)] means we get the current column and
                        // add the amount of traversed rows * the amount of traversed columns
                        // in a 2-dimensional array, this would be equal to indices[x][y]
            bitmap.SetPixel(x, y, palette[indices[x + (y * width)]]);
                        // SetPixel() takes in the x and y coordinate and an ARGB Color value
        }
    }
    return bitmap;
}
