Class SamplingFactory

java.lang.Object
  org.jpedal.images.SamplingFactory

public class SamplingFactory
extends java.lang.Object

Field Summary

static int	downsampleLevel current setting - do not set directly
static int	high (default setting) high will agressively reduce images bigger than twice their drawn size at 100% so a image which appears as 100x100 on the PDF but whose raw images is 250x250 will be stored as 125x125 image and not a 250x250 image
static boolean	isPrintDownsampleEnabled current setting - do not set directly
static int	medium medium will make sure images larger than page are reduced in size (often large scanned tiffs)
static int	none do nothing
static int	print_disable do not use down-sampling on printing
static int	print_enable use down-sampling on printing (which is default)

Constructor Summary

SamplingFactory()

Method Summary

static void	setDownsampleMode(int newLevel) PDFs contain images which may often be much larger than the actual space they occupy and they are reduced to fit the space alters image sampling to speed up program and reduce memory with the strategies high, medium, none, enable_printing, disable_printing
static void	setDownsampleMode(java.lang.String newLevel) PDFs contain images which may often be much larger than the actual space they occupy and they are reduced to fit the space alters image sampling to speed up program and reduce memory in with the strategies "high","medium", "none", "enable_printing", "disable_printing"
