Member Functions

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

Returns the gamma value of the image.

virtual bool mi::​neuraylib::​IImage_file::get_is_cubemap() const [pure virtual]

Indicates whether the image represents a cubemap.

Returns

if the image represents a cubemap, false otherwise.

virtual Uint32 mi::​neuraylib::​IImage_file::get_layers_size( Uint32 level = 0) const [pure virtual]

Returns the number of layers of the image.

Parameters

level
The mipmap level (always 0 if the image is not a mipmap).

Returns

The number of layers of the image.

virtual Uint32 mi::​neuraylib::​IImage_file::get_miplevels() const [pure virtual]

Returns number of miplevels.

virtual Uint32 mi::​neuraylib::​IImage_file::get_resolution_x( Uint32 level = 0) const [pure virtual]

Returns the resolution of the image in x direction.

Parameters

level
The mipmap level (always 0 if the image is not a mipmap).

Returns

The resolution of the image in x direction.

virtual Uint32 mi::​neuraylib::​IImage_file::get_resolution_y( Uint32 level = 0) const [pure virtual]

Returns the resolution of the image in y direction.

Parameters

level
The mipmap level (always 0 if the image is not a mipmap).

Returns

The resolution of the image in y direction.

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

Returns the pixel type of the image (or the requested channel). See Types for a list of supported pixel types.

virtual ITile* mi::​neuraylib::​IImage_file::read( Uint32 z, Uint32 level = 0) const [pure virtual]

Read pixels from the image file into a tile. This method will never be called if this instance was obtained from mi::neuraylib::IImage_plugin::open_for_writing().

Parameters

z
The z layer (for 3d textures or cubemaps).
level
The mipmap level (always 0 if the image is not a mipmap).

Returns

The tile with the read data, or nullptr in case of failures.

virtual bool mi::​neuraylib::​IImage_file::write( const ITile* tile, Uint32 z, Uint32 level = 0) [pure virtual]

Write pixels from a tile into the image file. This method will never be called if this instance was obtained from mi::neuraylib::IImage_plugin::open_for_reading().

Parameters

tile
The tile to read the data from.
z
The z layer (for 3d textures or cubemaps).
level
The mipmap level (always 0 if the image is not a mipmap).

Returns

true if the tile was successfully written, false otherwise.
