Detailed 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.

Member Function Documentation

get_gamma()

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.

get_layers_size()

virtual Uint32 mi::neuraylib::ICanvas_base::get_layers_size ( ) const

pure virtual

Returns the number of layers this canvas has.

get_resolution_x()

virtual Uint32 mi::neuraylib::ICanvas_base::get_resolution_x ( ) const

pure virtual

Returns the resolution of the canvas in x direction.

Implemented in mi::neuraylib::ICanvas_cuda.

get_resolution_y()

virtual Uint32 mi::neuraylib::ICanvas_base::get_resolution_y ( ) const

pure virtual

Returns the resolution of the canvas in y direction.

Implemented in mi::neuraylib::ICanvas_cuda.

get_type()

virtual const char * mi::neuraylib::ICanvas_base::get_type ( ) const

pure virtual

Returns the pixel type used by the canvas.

Types for a list of supported pixel types

set_gamma()

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.
