arParamLoad()

int arParamLoad	(	const char *	filename,
		int	num,
		ARParam *	param,
			...
	)

Load lens parameters from a file.

See the discussion under ARParam for more info.

Parameters

filename	Path to file from which to load the parameters. The file pointed to should be a file saved with arParamSave.
num	Number of ARParams to be loaded, normally 1.
param	Pointer to the ARParam structure into which the parameters will be read.

Returns

0 if successful, or -1 if an error occured.

arParamLoadExt()

int arParamLoadExt	(	const char *	filename,
		ARdouble	para[3][4]
	)

arParamLoadExtFromBuffer()

int arParamLoadExtFromBuffer	(	const void *	buffer,
		size_t	bufsize,
		ARdouble	para[3][4]
	)

arParamLoadFromBuffer()

int arParamLoadFromBuffer	(	const void *	buffer,
		size_t	bufsize,
		ARParam *	param
	)

Load lens parameters from a buffer.

See the discussion under ARParam for more info.

Parameters

buffer	Buffer from which the parameter(s) will be loaded. The buffer could be (for example) the contents of a parameter file read with fread().
bufsize	Size of the contents of buffer.
param	Pointer to the ARParam structure into which the parameters will be read.

Returns

0 if successful, or -1 if an error occured.

num	Number of ARParams to be saved, normally 1.
param	Pointer to the ARParam structure to save.

Returns

0 if successful, or -1 if an error occured.
