HPGS_API void hpgs_destroy_reader ( hpgs_reader * reader )

Destroys the given reader structure and frees all allocated resources of the HPGL reader.

HPGS_INTERNAL_API int hpgs_device_setrgb_all	(	hpgs_device *	dev,
		const hpgs_color *	rgb
	)

Simultaneously set the promary and the pattern color on a device.

HPGS_API int hpgs_device_stamp	(	hpgs_device *	dev,
		const hpgs_bbox *	bb,
		const char *	stamp,
		const char *	encoding,
		double	stamp_size
	)

This is a highlevel interface to stamp the device with a text prior to printing any data. This is used in order to print a 'draft' or 'obsoleted' mark to the paper.

If encodeing is a null pointer

HPGS_API hpgs_reader* hpgs_new_reader	(	hpgs_istream *	in,
		hpgs_device *	dev,
		hpgs_bool	multipage,
		int	v
	)

Contructs a HPGL reader on the heap using the given input device in and the given output vector drawing device dev.

The argument multipage specifies, whether the reader processes more than one page.

The argument v specifies the verbosity of the HPGL reader. A value of 0 forces the reader to not report anything to hpgs_log(). Value of 1 or 2 give diagnostics output to hpgs_log() with increasing volume.

You do not have to call neither hpgs_close on in nor hpgs_destroy on dev.

In the case of an error, a null pointer is returned. This only happens, if the system is out of memory.

HPGS_API int hpgs_read	(	hpgs_reader *	reader,
		hpgs_bool	finish
	)

Interprets the input stream associated with reader and passes the result to the associated vector device.

The argument finish specifies, whether this is the last file written to the underlying hpgs_device. If finish is HPGS_TRUE, hpgs_device_finish is called. Otherwise, another input stream may be attached using hpgs_reader_attach and hpgs_read may be called again. This way, multiple input files may collated together in a single output file.

The function return 0 upon success. A value of -1 is returned, when an error is encountered.

You have to call hpgs_reader_get_error in order to retrieve the error message in the latter case.

HPGS_API void hpgs_reader_interrupt ( hpgs_reader * reader )

Interrupt a currently running call to hpgs_reader_read from another thread. There's no guarantee when hpgs_read will terminate after calling hpgs_reader_interrupt. If the reader is currently performing a time-consuming task like rendering a large imge to the device, hpgs_read may continue for several seconds after this call.
