dmFXSetupScanlineBuffer(3dm)			  dmFXSetupScanlineBuffer(3dm)

NAME    [Toc]    [Back]

     dmFXSetupScanlineBuffer - get information about a special-effects image

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/fx_buffer.h>

     DMstatus dmFXSetupScanlineBuffer    [Toc]    [Back]
	   ( DMfxbuffer* buffer,
	     PRX_ScanlineBuffer* returnInfo )

PARAMETERS    [Toc]    [Back]

     buffer	  A special-effects image buffer that has been set up for
		  access with dmFXSetupInputImageBuffer	or

     returnInfo	  A PRX_ScanlineBufferRec structure, which will	be filled in.

DESCRIPTION    [Toc]    [Back]

     dmFXSetupScanlineBuffer returns information about an image	buffer,
     including:	data, a	pointer	to the image data, rowBytes the	number of
     bytes (stride) for	each row of the	image, bounds, the size	of the image.

     This function sets	all fields of the PRX_ScanlineBufferRec	structure,
     except for	appPrivate.

     Under normal circumstances, the number of bytes for each row will be four
     times the buffer width.  Applications that	use DMfxbuffers	can count on
     this.  It can be useful, when debugging plugins, to create	buffers	that
     have a larger internal width.  If you are using the debug version of
     libfxplugutils, setting the environment variable FX_STRANGE_ROWBYTES to
     YES will cause it to create buffers where the width of the	storage	area
     is	greater	than is	needed.

RETURN VALUES    [Toc]    [Back]

     It	returns	DM_SUCCESS or DM_FAILURE.  In the case of failure, error
     information can be	obtained from dmGetError(3dm).
