| channel_convert | |
| Converting from one channel type to another
Conversion is done as a simple linear mapping of one channel range to the other, such that the minimum/maximum value of the source maps to the minimum/maximum value of the destination. One implication of this is that the value 0 of signed channels may not be preserved! | |
| channel_multiply | |
| Multiplying unsigned channel values of the same type. Performs scaled multiplication result = a * b / max_value. | |
| channel_invert | |
| Returns the inverse of a channel. result = max_value - x + min_value. | |
Classes | |
| struct | channels_are_compatible |
| Predicate metafunction returning whether two channels are compatible
Channels are considered compatible if their value types (ignoring constness and references) are the same. More... | |
