Module raster - Basic raster graphics support
Basic raster graphics support. This module provides basic data types for two-dimensional bitmap ("raster") graphics. To display graphics, you'll want to use a module like sdlraster.

Declarations
raster.inc:44Data type RASTER
DATA TYPE RASTER
A bitmap image.
This is really a MOBILE [][]INT, with the first dimension being the Y coordinate and the second the X coordinate. Each element represents an RGB-colourspace pixel in #AARRGGBB format, with eight bits for each of red, green, blue and alpha. (Most things ignore the alpha component.)
The pixel representation uses the native endianism, so if you retype it to an array of BYTEs then the order of the components will vary between platforms.
It's sometimes useful to have a sentinel value of this type (for example, to use as a poison value in process networks); a zero-by-zero raster can be used for this purpose (MOBILE [0][0]INT).
raster.inc:49Record RASTER.EVENT
DATA TYPE RASTER.EVENT
An input event.
raster.inc:57Variable id
INT
Identifier.
- For keyboard events, this is the key symbol -- a Unicode character, or one of
RASTER.KEY. - For mouse button events, this is one of
RASTER.BUTTON.
raster.inc:61Variable mod
INT
Modifier keys.
- For keyboard and mouse button events, this is the modifier state -- one or more of
RASTER.MODbitwise-ORed together.
raster.inc:64Variable x, y
INT16
Pointer coordinates.
- For mouse events, this is the pointer position.
