iflPPM(3)	  Image	Format Library C++ Reference Manual	     iflPPM(3)

NAME    [Toc]    [Back]

     iflPPM - PPM file format

HEADER FILE    [Toc]    [Back]

     #include <ifl/iflPPM.h>

DESCRIPTION    [Toc]    [Back]

     This IFL format provides support for reading and writing image files with
     the Portable Bitmap format	(PPM). This file format	is suitable for
     archiving multicolor and monochromatic image data.	It includes the
     formats PPM, PGM, PBM, PNM, RPPM, RPGM, RPBM, and RPNM.

     The default extensions for	image files in the PPM format are '.ppm', When
     you create	a file with one	of these extensions IFL	will assume you	want
     the PPM format, unless you	override it with the iflFormat parameter.

     In	addition to all	the standard iflFile methods, this format supprts an
     number of format specific operations via the getItem() and	setItem()
     methods.  The tag values supported	by theses methods are enumerated in
     the following sections.

TAG VALUES FOR GET ITEM    [Toc]    [Back]

     The followng tag values are supported with	getItem():

	  iflStatus getItem(iflPPMwriteASCII, int* on)

     This function returns TRUE	in 'on'	if ASCII output	is enabled; FALSE

TAG VALUES FOR SET ITEM    [Toc]    [Back]

     The followng tag values are supported with	setItem():

	  iflStatus setItem(iflPPMwriteASCII, int on)

     This function can be used to enable ASCII output while writing a PPM
     file, by setting 'on' = TRUE.
