mi::neuraylib::ICanvas_base Class Reference

[Mi_neuray_mdl_sdk_misc]

Description

Abstract interface for a canvas (base class). This interface is the base class for all canvases. It holds the common functionality of all different canvas interfaces, i.e., the resolution of the canvas.

virtual Float32 mi::​neuraylib::​ICanvas_base::get_gamma() const [pure virtual]

Returns the gamma value. The gamma value should be a positive number. Typical values are 2.2 for LDR pixel types, and 1.0 for HDR pixel types.

virtual Uint32 mi::​neuraylib::​ICanvas_base::get_layers_size() const [pure virtual]

Returns the number of layers this canvas has.

virtual Uint32 mi::​neuraylib::​ICanvas_base::get_resolution_x() const [pure virtual]

Returns the resolution of the canvas in x direction.

virtual Uint32 mi::​neuraylib::​ICanvas_base::get_resolution_y() const [pure virtual]

Returns the resolution of the canvas in y direction.

virtual const char* mi::​neuraylib::​ICanvas_base::get_type() const [pure virtual]

Returns the pixel type used by the canvas.

virtual void mi::​neuraylib::​ICanvas_base::set_gamma( Float32 gamma) [pure virtual]

Sets the gamma value.

Note:

This method just sets the gamma value. It does not change the pixel data itself.
