Detailed Description

template<typename ConditionT, typename LhsT, typename RhsT>
class ImFusion::ImageMath::internal::SelectTpl< ConditionT, LhsT, RhsT >

Specialization of ExprBaseTpl for ternary (condition ?

case_true : case_false) operators using template optimization

Template Parameters

ConditionT	The first component of this expression is used to determine whether to return lhs or rhs.
LhsT	The expression that is returned if condition is true
RhsT	The expression that is returned if condition is false

Please note that in addition to the CPU operator() method this also provides the evalString() method which will be used to formulate the expression in e.g. a GLSL shader.
