The Graphics console unit provides access to the underlying framebuffer device as a pixel interface that allows putting blocks (or rectangles) of pixel data on to the screen or getting rectangles of pixel data from the screen. Functions are also included to copy a rectangle from one part of the screen to another and to put text (with a specified font) on to the screen.

Most image formats either consist of, or can be decoded to, a block of data that is a number of horizontal rows each with a number of pixels (columns) with each pixel containing color information in a certain bit size (8/16/24/32) and format (RGB/BGR/RGBA etc).

If the data exists in memory as a single contiguous block with each row following directly after the previous row then that can be passed directly to the functions in this unit (eg GraphicsWindowDrawImage) to be drawn on the screen.

Many graphics libraries do image manipulation, rendering and compositing to a memory buffer in a form that is compatible with the functions in this unit so a complex image can be constructed in memory and then transferred to the screen in a single operation. This is sometimes referred to as a bit block transfer or BitBlt and is a very standard technique for rendering both text and images to a framebuffer device.

This unit extends the console unit by creating a new type of console window (WINDOW_MODE_GRAPHICS) and therefore allows both text console windows and graphics console windows to co-exist on the screen at once.

The functions in this unit cannot be used to draw on a text console window (WINDOW_MODE_TEXT) and vice versa the functions in the console unit cannot be used to draw on a graphics console window.

Like the console unit, the graphics console supports setting a viewport for a specified window to allow masking the area to be written to. However the graphics console does not support tracking a cursor X and Y position. Setting a window as the default is also not supported since that functionality is purely intended to support the RTL functions for text output.

Graphics windows can only be created on console devices which have a mode of CONSOLE_MODE_PIXEL.

Notes: Unlike the Console unit, Graphics console coordinates are always based on pixels not characters. Graphics console coordinates begin at 0,0 and extend to Width - 1, Height - 1. Graphics Window coordinates X,Y are always based on pixels, beginning at 0,0 and extending to Cols - 1, Rows - 1.

Handle	The handle of the window to draw on
X	The left starting point of the image (relative to current viewport)
Y	The top starting point of the image (relative to current viewport)
Stream	A stream containing the image data in a contiguous block of pixel rows
Width	The width in pixels of a row in the image data
Height	The height in pixels of all rows in the image data
Format	The color format of the image data (eg COLOR_FORMAT_ARGB32) Pass COLOR_FORMAT_UNKNOWN to use the window format
Stride	The distance in bytes between each row of pixels (Optional)
Invert	If True invert the image so the first row is the bottom and the last row is the top
Return	ERROR_SUCCESS if completed or another error code on failure
Note	For Graphics Console functions, Viewport is based on screen pixels not characters.

function GraphicsWindowImageToStream(Handle:TWindowHandle; X,Y:LongWord; Stream:TStream; Width,Height,Format,Stride:LongWord; Invert:Boolean):LongWord;

Description: Get an image from an existing console window to a supplied stream

Handle	The handle of the window to get from
X	The left starting point of the image (relative to current viewport)
Y	The top starting point of the image (relative to current viewport)
Stream	A stream large enough to hold the image in a contiguous block of pixel rows
Width	The width in pixels of a row of the image
Height	The height in pixels of all rows of the image
Format	The color format to store in the image data (eg COLOR_FORMAT_ARGB32) Pass COLOR_FORMAT_UNKNOWN to use the window format
Stride	The distance in bytes between each row of pixels (Optional)
Invert	If True invert the image so the first row is the bottom and the last row is the top

-'''Ultibo Graphics Console interface unit'''
+'''Ultibo Graphics Console Interface unit'''
 The Graphics console unit provides access to the underlying framebuffer device as a pixel interface that allows putting blocks (or rectangles) of pixel data on to the screen or getting rectangles of pixel data from the screen. Functions are also included to copy a rectangle from one part of the screen to another and to put text (with a specified font) on to the screen.
@@ Line 15: / Line 15: @@
 Many graphics libraries do image manipulation, rendering and compositing to a memory buffer in a form that is compatible with the functions in this unit so a complex image can be constructed in memory and then transferred to the screen in a single operation. This is sometimes referred to as a bit block transfer or BitBlt and is a very standard technique for rendering both text and images to a framebuffer device.
-This unit extends the console unit by creating a new type of console window (WINDOW_MODE_GRAPHICS) and  therefore allows both text console windows and graphics console windows to co-exist on the screen at once.
+This unit extends the console unit by creating a new type of console window (WINDOW_MODE_GRAPHICS) and therefore allows both text console windows and graphics console windows to co-exist on the screen at once.
 The functions in this unit cannot be used to draw on a text console window (WINDOW_MODE_TEXT) and vice versa the functions in the console unit cannot be used to draw on a graphics console window.
-Like the console unit, the graphics console supports setting a viewport for a specified window to allow masking the area to be written to. However the graphics console does not support a tracking a cursor X and Y position. Setting a window as the default is also not supported since that functionality is purely intended to support the RTL functions for text output.

 Graphics windows can only be created on console devices which have a mode of CONSOLE_MODE_PIXEL.
