Detailed Description

Function Documentation

boolvec* surfit::pnts_load	(	const char *	filename,
		const char *	pntsname = NULL
	)

Tcl syntax:

pnts_load filename "pntsname"

Description:

reads points named 'pntsname' from surfit datafile

Example:

pnts_load "C:\\my_points.dat" "my_points"

bool pnts_load_shp	(	const char *	filename,
		const char *	pntsname = "*",
		const char *	param = "VALUE"
	)

Tcl syntax:

pnts_load_shp filename "pntsname" "param"

Description:

reads points from ESRI shape file and names them "pntsname"

Example:

pnts_load_shp "C:\\my_points.shp" "my_points" "VALUE"

Implemented in library:

libsurfit_io

boolvec* surfit::pnts_read	(	const char *	filename,
		const char *	pntsname = NULL,
		int	col1 = 1,
		int	col2 = 2,
		int	col3 = 3,
		int	col4 = 0,
		const char *	delimiter = " \t",
		int	skip_lines = 0,
		int	grow_by = 250
	)

Tcl syntax:

pnts_read filename "pntsname" col1 col2 col3 col4 "delimiter" skip_lines grow_by

Description:

reads points from formatted text file

Parameters

filename	name of formatted text file
pntsname	name for points object
col1	column with X coordinates
col2	column with Y coordinates
col3	colimn with Z values
col4	column with names. If col4 equal to 0, then no names will be read
delimiter	delimiter between columns. May be " ", "\t", "," or other symbols
skip_lines	number of lines to skip header
grow_by	=250

Examples:

• pnts_read "C:\\points.txt" "points" 1 2 3 0 " " 0
• pnts_read "C:\\points_geq.txt" "points_geq" 1 2 3 3 " " 0

boolvec* surfit::pnts_save	(	const char *	filename,
		const char *	points_name = "*"
	)

Tcl syntax:

pnts_save "filename" points_name

Description:

saves points to surfit datafile

Example

pnts_save "C:\\points.dat" "my_points"

bool pnts_save_shp	(	const char *	filename,
		const char *	points_name = "*"
	)

Tcl syntax:

pnts_save_shp "filename" points_name

Description:

saves points to ESRI shapefile format

Example

pnts_save_shp "C:\\points.shp" "my_points"

Implemented in library:

libsurfit_io

boolvec* surfit::pnts_write	(	const char *	filename,
		const char *	points_name = "*",
		const char *	delimiter = "\t"
	)

Tcl syntax:

pnts_write "filename" points_name "delimiter"

Description:

saves points to formatted text file
