void XSurface::allocateData

(

)

[protected, virtual]

Allocate data

Reimplemented from PieDock::Surface.

Referenced by XSurface().

int XSurface::determineBitsPerPixel

(

int

depth

)

[protected, virtual]

Determine how many bits are used by the given color depth; this depends on X which tries to align the pixels on a multiple of 4 for speed; this means 24 bit RGB is actually 32 bits per pixel

Parameters:

depth

- color depth

void XSurface::freeData

(

)

[protected, virtual]

Free data

Reimplemented from PieDock::Surface.

Referenced by ~XSurface().
