| make an empty channel map | |
| ChannelMap (const DD::Image::ChannelSet &channels) | |
| make a channel map based on a ChannelSet | |
| operator const ChannelSet & () const | |
| get a reference to the ChannelSet | |
| bool | contains (DD::Image::Channel z) const |
| return whether or not the channel passed in is part of this set | |
| size_t | size () const |
| return the number of channels in this map | |
| bool | empty () const |
| return whether this ChannelMap is empty | |
| bool | containsAll (const DD::Image::ChannelSet &want) const |
| returns true if this ChannelMap contains all of the channels in want | |
| int | chanNo (Channel z) const |
| bool | operator== (const ChannelMap &chans) const |
| compare to another ChannelMap. Returns true if they represent the same channels. | |
| bool | operator== (const ChannelSet &chans) const |
| compare to a ChannelSet. Returns true if they represent the same channels. | |
| int DD::Image::ChannelMap::chanNo | ( | Channel | z | ) | const [inline] |
return the index of the passed in channel within the ChannelMap (e.g. Chan_Green in Mask_RGB is 1), Chan_Alpha in Mask_RGBA is 3
