The API (Application Programming Interface) for graphics output that runs under EUROS is hardware-independent, thus enabling the creation of device-independent graphical representations.
The EUROS graphics libraries provide a set of primitives for reading and writing individual pixels, drawing lines, rectangles, ellipses, polygons and circles. Rectangular areas can be copied and there are also functions available for drawing text. The device context must be specified for almost all functions. This provides the basic information to which the function refers. Information is included for describing the drawing area and the various attributes such as font, font color, clipping area, drawing mode, etc.
