Detailed Description

The CColor object represents a color on a surface (including the screen, since it's a surface), and it's stored as a 32-bit integer, since virtually all architectures store a pixel color using <= 32 bits.

Note that this class isn't abstract, partially for performance reasons; making it abstract would require a vtable, increasing the size of the color, and virtual functions would slow down the methods of a class that is probably going to be used quite a bit. Most of all, however, this is the kind of structure that really doesn't have much of an actual need *need* to have multiple implementations, and it's easier to have the class just ask the video system manager for architecture-specific concerns than it is to subclass the color object in every concrete video driver implementation.

Constructor & Destructor Documentation

CColor::CColor (  uint32  n_color = 0  )  [inline]

Create a color with the given surface-specific color value (i.e., the CColor object doesn't ask the CVideoSystem anything about conversion, it just stores the given number directly). Definition at line 207 of file cvideo.h.

CColor::CColor (  uint8  r, uint8  g, uint8  b )  [inline]

Creates a new color with the given red, green, and blue components (from 0-255), creating the 32-bit color value by asking the CVideoSystem to make it for us. Definition at line 212 of file cvideo.h. References CSingletonManager< CVideoSystem >::get_instance(), and CVideoSystem::make_color().
