Statements and procedures for working with 2D graphics.
The statements and procedures listed here provide ways of drawing to the screen. Image buffers can be created and blitted to the screen using a variety of blending methods. Palette colors can be retrieved or set in graphics modes that support them.

Working with ColorDrawing to Image BuffersImage Buffer Creation
Sets the foreground and background color to use with the drawing procedures.
Gets or sets color table information in paletted modes.
Returns a color value for hi/truecolor modes.
Returns a color value including alpha (transparency) for hi/truecolor modes.
Gets a pixel value from an image buffer or screen.
Plots a single pixel on an image buffer or screen.
Plots a line of pixels on an image buffer or screen.
Plots circles and ellipses on an image buffer or screen.
Draws in a sequence of commands on an image buffer or screen.
Writes text to an image buffer or screen.
Fills an area with color on an image buffer or screen.
Creates an image buffer from a portion of another image buffer or screen.
Creates an image buffer of a certain size and pixel depth.
Frees an image buffer resource.
Converts a row of pixels in an image buffer to a different color depth.
Retrieves useful information about an image buffer
Creates an image buffer from a file.
Saves an image buffer to a file.
Blitting Image Buffers
Blits an image buffer to another image buffer or screen.Blending Methods
Saturated addition of the source and target components.
Blend using a uniform transparency or the image buffer's alpha channel.
Combine the source and target components using a bitwise And
Combine the source and target components using a bitwise Or
Directly copy pixel colors from the source to the destination.
Pixels matching the transparent mask color are not blitted.
Allows a custom blending procedure to be used.
Combine the source and target components using a bitwise Xor
