Member Function Documentation

const eDvbColor * cPalette::AllColors (  int &    NumColors )

Returns a pointer to the complete color table and stores the number of valid entries in NumColors. If no colors have been stored yet, NumColors will be set to 0 and the function will return NULL. Definition at line 92 of file osdbase.c. References color, eDvbColor, and numColors.

eDvbColor cPalette::GetColor (  int    Index )  [inline]

const eDvbColor * cPalette::NewColors (  int &    FirstColor, int &    LastColor )

With every call this function returns a consecutive range of color entries that have been added since the last call. The return value is the address of the first new color, and the index of the first and last new color are returned in the given int parameters. If there are no new color entries, NULL will be returned. Definition at line 79 of file osdbase.c. References color, eDvbColor, fetched, and numColors. Referenced by cDvbOsd::CommitWindow().
