Detailed Description

Harlequin VariData (external) raster discarding backend, HVDNONE, and raw raster backend, HVDRAW.

This file implements an external Harlequin VariData backend. It receives raster data for each element from the RIP via a framebuffer, caches it, and composes an output page from the element data. The HVDNONE backend then discards the data, whereas the HVDRAW backend writes the data out to disk, along with an XML file detailing which elements are used by which pages.

It illustrates:

Using libHVD to handle the required Harlequin VariData event handlers
Additional event handlers to capture the XML data for the page.
use of a framebuffer to receive raster data from the RIP
asynchronous output of pages triggered by the Page Ready event

It does not illustrate:

synchronization on cache elements

Macro Definition Documentation

◆ HVD_ELEMENT_FILEFORMAT

#define HVD_ELEMENT_FILEFORMAT "%i%?-N%?-S%?-03r.raw"

Fileformat string for the HVD element raw files. This is substituted for the leaf of the filename generated by HVD_FILEFORMAT when outputting HVD elements.

◆ HVD_FILEFORMAT

#define HVD_FILEFORMAT "%f-%p%?-N%?-S%?-T.raw"

Fileformat string for the final raw files.

◆ HVD_PAGES_FILEFORMAT

#define HVD_PAGES_FILEFORMAT "%f-pages_%p.xml"

Fileformat string for the XML file containing the page and element info.

Typedef Documentation

◆ HVD_RASTER_handle

typedef struct HVD_RASTER_handle HVD_RASTER_handle

Structure holding job information

Function Documentation

◆ HVDRAST_RasterDestination()

static RASTER_result HVDRAST_RasterDestination	(	void *	pJobContext,
		RASTER_DESTINATION *	pRD,
		int32	sheetIndex
	)

static

This function allows the raster backend to provide a memory address range into which to render.

See also: SwLeRASTERDESTINATION in skinkit.h

◆ HVDRAST_RasterRequirements()

static RASTER_result HVDRAST_RasterRequirements	(	void *	pJobContext,
		RASTER_REQUIREMENTS *	pRasterRequirements,
		RasterDescription *	pRD
	)

static

This function gives the raster backend the details of the raster it's about to be handed.

The framebuffer memory is allocated here once the page dimensions are known.

See also: SwLeRASTERREQUIREMENTS in skinkit.h

◆ HVDRAST_RegisterHandlers()

HqBool HVDRAST_RegisterHandlers ( void )

Register the raster backend and event handlers.

Register the required external Harlequin VariData event handlers This function is called from RegisterHandlers()

Returns: TRUE if all the handlers are successfully registered

◆ mem_acquire()

static void* mem_acquire	(	size_t	size,
		uint32	id,
		void *	data,
		HqnResult *	perr
	)

static

Allocation function for framebuffer memory, using gfSysAlloc.

◆ mem_raster()

static uint8* mem_raster	(	void *	handle,
		size_t	offset,
		size_t	size
	)

static

Raster address function for framebuffer memory allocated using gfSysAlloc.

◆ mem_release()

static void mem_release	(	void *	handle,
		size_t	size,
		void *	data
	)

static

Release function for framebuffer memory, using gfSysAlloc.

◆ none_mem_hvd_output_page()

static HVD_result none_mem_hvd_output_page ( HVD_page_output * page )

static

Callback function for libHVD to output an HVD page.

Parameters

[in] page The output page description from libHVD.

Return values

HVD_SUCCESS The page was output successfully

Returns: One of the HVD_ERROR_* error codes, or any other return value greater than MON_CLASS_ERROR is an error UID. HVD_ERROR_* codes should be translated to monitor UID errors using HVD_result_translate(). The error subclass, PS error type, and UID for the error can be deconstructed using the macros in monevent.h.

◆ none_shm_hvd_output_page()

static HVD_result none_shm_hvd_output_page ( HVD_page_output * page )

static

Callback function for libHVD to output an HVD page.

Parameters

[in] page The output page description from libHVD.

Return values

HVD_SUCCESS The page was output successfully

Returns: One of the HVD_ERROR_* error codes, or any other return value greater than MON_CLASS_ERROR is an error UID. HVD_ERROR_* codes should be translated to monitor UID errors using HVD_result_translate(). The error subclass, PS error type, and UID for the error can be deconstructed using the macros in monevent.h.

◆ raw_hvd_raster_finish()

static RASTER_result raw_hvd_raster_finish	(	void *	pJobContext,
		RASTER_handle *	handlep,
		RasterDescription *	rd,
		RASTER_result	result
	)

static

Raster finish function for HVDRAW output when outputting completed HVD pages. This saves the page and element XML file before finishing the raster in the normal way.

◆ raw_mem_hvd_output_page()

static HVD_result raw_mem_hvd_output_page ( HVD_page_output * page )

static

Callback function for libHVD to output an HVD page.

Parameters

[in] page The output page description from libHVD.

Return values

HVD_SUCCESS The page was output successfully

Returns: One of the HVD_ERROR_* error codes, or any other return value greater than MON_CLASS_ERROR is an error UID. HVD_ERROR_* codes should be translated to monitor UID errors using HVD_result_translate(). The error subclass, PS error type, and UID for the error can be deconstructed using the macros in monevent.h.

◆ raw_shm_hvd_output_page()

static HVD_result raw_shm_hvd_output_page ( HVD_page_output * page )

static

Callback function for libHVD to output an HVD page.

Parameters

[in] page The output page description from libHVD.

Return values

HVD_SUCCESS The page was output successfully

Returns: One of the HVD_ERROR_* error codes, or any other return value greater than MON_CLASS_ERROR is an error UID. HVD_ERROR_* codes should be translated to monitor UID errors using HVD_result_translate(). The error subclass, PS error type, and UID for the error can be deconstructed using the macros in monevent.h.

◆ save_pages_info()

static HqBool save_pages_info	(	DEVICELIST *	dev,
		RasterDescription *	pRasterDescription
	)

static

Writes the XML page and element info held by gPagesInfo to a file.

Parameters

[in]	dev	The device to output the XML file on.
[in]	pRasterDescription	The raster description for the page

Return values

TRUE	if successful
FALSE	If the page description could not be saved
