A line can be drawn at any angle using the following sequence:­
<ESC> [ ? 18 ; 4 ; x1 ; y1 ; x2 ; y2 z
where x1 (pixel number) and y1 (row number) give the pixel
coordinates of the start of the line, and x2, y2 give the pixel
coordinates of the end of the line.
Note that all coordinates start at zero, i.e. the top left pixel is
located at (0, 0).
To draw a solid box, use one of the following sequences.
Solid black box <ESC> [ ? 18 ; 2 ; x1 ; y1 ; x2 ; y2 z
Solid white box <ESC> [ ? 18 ; 3 ; x1 ; y1 ; x2 ; y2 z
where x1 (pixel number) and y1 (row number) give the pixel
coordinates of the start of the line, and x2, y2 give the pixel
coordinates of the end of the box.
When downloading a graphics bitmap image, enter the position
and size of the image in the following sequence.
<ESC> [ ? 18 ; 1 ; x1 ; y1; width ; height z data
where x1 (byte number) and y1 (row number) are the coordinates
of the top left corner, and width, height give the width (in bytes)
and height (in rows) of the image. data is the pixel data as shown
in table 7.
