Detailed Description

Function Documentation

readPointsBIN()

bool GEOM_FADE2D::readPointsBIN	(	const char *	filename,
		std::vector< Point2 > &	vPointsIn,
		bool	bWithHeader = true
	)

Reads points from a binary file.

Parameters

filename	is the input file
vPointsIn	is used to return the points
bWithHeader	specifies if the file contains a header (like the ones written by writePointsBIN()) or if the file contains just a sequence of double precision coordinates - use false in this case.

readSegmentsBIN()

bool GEOM_FADE2D::readSegmentsBIN	(	const char *	filename,
		std::vector< Segment2 > &	vSegmentsOut
	)

Reads segments from a binary file of type 21 or 31

writeSegmentsBIN()

readXY()

bool GEOM_FADE2D::readXY	(	const char *	filename,
		std::vector< Point2 > &	vPointsOut
	)

Reads points from an ASCII file. Expected file format: Two coordinates (x y) per line, whitespace separated.

writePointsASCII() [1/2]

bool GEOM_FADE2D::writePointsASCII	(	const char *	filename,
		const std::vector< Point2 * > &	vPointsIn
	)

Writes points to an ASCII file, two coordinates (x y) per line, whitespace separated.

Note

Data exchange through ASCII files is easy and convenient but floating point coordinates are not necessarily exact when represented as decimal numbers. If the tiny rounding errors can't be accepted in your setting you are advised to write binary files, (use writePointsBIN() )

writePointsASCII() [2/2]

bool GEOM_FADE2D::writePointsASCII	(	const char *	filename,
		const std::vector< Point2 > &	vPointsIn
	)

Write points to an ASCII file

readPointsASCII()

writePointsBIN() [1/2]

bool GEOM_FADE2D::writePointsBIN	(	const char *	filename,
		std::vector< Point2 * > &	vPointsIn
	)

Writes points to a binary file

See also

readPointsBIN()

writePointsBIN() [2/2]

bool GEOM_FADE2D::writePointsBIN	(	const char *	filename,
		std::vector< Point2 > &	vPointsIn
	)

File format:
int filetype (20)
size_t numPoints (vPointsIn.size())
double x0
double y0
double z0
...
double xn
double yn
double zn

Note

Since version 1.64 the binary file format written by 32-bit machines is identical with the file format of x64 machines i.e., the numPoints value is always 8 bytes, not 4. This change affects only 32-bit programs.

writeSegmentsBIN()

bool GEOM_FADE2D::writeSegmentsBIN	(	const char *	filename,
		std::vector< Segment2 > &	vSegmentsIn
	)

Binary file format:
int filetype (21)
size_t numSegments (vSegmentsIn.size())
double x0_source
double y0_source
double x0_target
double y0_target
...
double xn_source
double yn_source
double xn_target
double yn_target

Note

Since version 1.64 the binary file format written by 32-bit machines is identical with the file format of x64 machines i.e., the numSegments value is always 8 bytes, not 4. This change affects only 32-bit programs.
