The Writer includes support for the E57_EXT_surface_normals extension.

Constructor & Destructor Documentation

◆ Writer() [1/2]

e57::Writer::Writer	(	const ustring &	filePath,
		const WriterOptions &	options )

Writer constructor.

Parameters

[in]	filePath	Path to E57 file
[in]	options	Options to be used for the file

◆ Writer() [2/2]

e57::Writer::Writer	(	const ustring &	filePath,
		const ustring &	coordinateMetadata = {} )

explicit

Writer constructor (deprecated).

Parameters

[in]	filePath	Path to E57 file
[in]	coordinateMetadata	Information describing the Coordinate Reference System to be used for the file

Deprecated: Will be removed in 4.0. Use Writer( const ustring &filePath, const WriterOptions &options ) instead.

Deprecated: Will be removed in 4.0. Use Writer( ustring, WriterOptions ).

Member Function Documentation

Note: data3DHeader may be modified (adding a guid or adding missing, required fields).

Parameters

[in,out]	data3DHeader	metadata about what is included in the buffers
[in]	buffers	pointers to user-provided buffers containing the actual data

Returns: Returns the index of the new scan's data3D block.

[in]	groupCount	size of each of the buffers given
[in]	idElementValue	buffer with idElementValue indices for this group
[in]	startPointIndex	buffer with starting indices in to the "points" data vector for the groups
[in]	pointCount	buffer with sizes of the groups given

Returns: Return true if successful, false otherwise

◆ WriteImage2DData() [1/2]

		Image2DProjection	imageProjection,
		int64_t	startPos,
		void *	buffer,
		int64_t	byteCount )

This function writes the Image2D data to the file.

Note: image2DHeader may be modified (adding a guid or adding missing, required fields).

Parameters
