struct  dynamic_xy_step_type< View >
 Returns the type of a view that has a dynamic step along both X and Y. More...
 
struct  dynamic_xy_step_transposed_type< View >
 Returns the type of a transposed view that has a dynamic step along both X and Y. More...
 
class  color_convert_deref_fn< SrcConstRefP, DstP, CC >
 Function object that given a source pixel, returns it converted to a given color space and channel depth. Models: PixelDereferenceAdaptorConcept. More...
 
struct  color_converted_view_type< SrcView, DstP, CC >
 Returns the type of a view that does color conversion upon dereferencing its pixels. More...
 
struct  nth_channel_deref_fn< SrcP >
 Function object that returns a grayscale reference of the N-th channel of a given reference. Models: PixelDereferenceAdaptorConcept.If the input is a pixel value or constant reference, the function object is immutable. Otherwise it is mutable (and returns non-const reference to the n-th channel) More...
 
struct  nth_channel_view_type< View >
 Given a source image view type View, returns the type of an image view over a single channel of ViewIf the channels in the source view are adjacent in memory (such as planar non-step view or single-channel view) then the return view is a single-channel non-step view. If the channels are non-adjacent (interleaved and/or step view) then the return view is a single-channel step view. More...
 
struct  kth_channel_deref_fn< K, SrcP >
 Function object that returns a grayscale reference of the K-th channel (specified as a template parameter) of a given reference. Models: PixelDereferenceAdaptorConcept.If the input is a pixel value or constant reference, the function object is immutable. Otherwise it is mutable (and returns non-const reference to the k-th channel) More...
 
struct  kth_channel_view_type< K, View >
 Given a source image view type View, returns the type of an image view over a given channel of View.If the channels in the source view are adjacent in memory (such as planar non-step view or single-channel view) then the return view is a single-channel non-step view. If the channels are non-adjacent (interleaved and/or step view) then the return view is a single-channel step view. More...

Last updated on March 9, 2007 / Methods for creating shallow image views from raw pixel data or from other image views - / flipping horizontally or vertically, axis-aligned rotation, a subimage, subsampled / or n-th channel image view. Derived image views are shallow copies and are fast to construct.
