Detailed Description

A namespace containing functions that implement drawing primitives on a "Target" object that must have the following methods:

• setPixel(x,y)
• drawHLine(x1,y,x2) draws [x1,x2)
• drawVLine(x,y1,y2) draws [y1,y2)

Further, the Target interface must be stateful with respect to drawing modes and colors (i.e. these cannot be passed through these functions).

template<class Target> void ixion::drawing_functions::drawLine (  Target &    target, int    x1, int    y1, int    x2, int    y2 )

Draws a line from [(x1,y1),(x2,y2)), i.e. leaves out the last pixel. Set manually if needed. This is done to allow faciliating the drawing of multiple lines in-a-row. Definition at line 72 of file ixlib_drawing_functions.hh. Referenced by drawPolygon().
