How to work with Sprite - Byte Array Assembly x86

Question

In the last days, while I'm working on a project, I was introduced to the sprite - Byte Array.

Unfortunately, I didnt find out any kond of information about the sprite which can tell me mote about what is this and how it's works.

I really be pleased if you can give me some information and examples for sprite.

A sprite is basically an image with a transparent background color or alpha channel which can be positioned on the screen and moved (usually involving redraw the background over the old position). In the case of an animated sprite, the sprite may consist of several actual images making up the frames of the animation. The format of the image depends entirely on the hardware and/or technology being used to draw or render it. For speed, the dimensions are usually powers of two (8,16,32,64 etc) but this may not be necessary for modern hardware.

Traditionally (read: back in my day), you might have a 320x200x256 screen resolution and a 16x16x256 sprite with color 0 being transparent. Each refresh of the screen would begin with redrawing the background under the sprites, taking a copy of the background under their new position and then redrawing only the visible colors of every sprite in their new position.

With modern hardware, however, it is more efficient to pass data in a format that the driver can handle (hopefully in the graphics accelerator) rather than do everything by hand.
