Member Function Documentation

void XSurface::allocateData ( )

protectedvirtual

Allocate data

Reimplemented from PieDock::Surface.

Referenced by XSurface().

int XSurface::determineBitsPerPixel ( int depth )

protectedvirtual

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 ( )

protectedvirtual

Free data

Reimplemented from PieDock::Surface.
