public class PdfDecoder
extends PdfPanel
implements java.awt.print.Printable, java.awt.print.Pageable

Provides an object to decode pdf files and provide a rasterizer if required - Normal usage is to create instance of PdfDecoder and access via public methods. Examples showing usage in org.jpedal.examples - Inherits indirectly from JPanel so can be used as a standard Swing component -

Extends other classes to separate out GUI and business logic but should be regarded as ONE object and PdfPanel should not be instanced - We recommend you access JPedal using only public methods listed in API

Recommend way to create a PdfDecoder if no rendering of page may be required
Otherwise use PdfDecoder()

Method Summary

void	addAdditionalPage(org.jpedal.render.DynamicVectorRenderer dynamicRenderer, int pageWidth, int origPageWidth) used by Storypad to display split spreads not aprt of API
void	addExternalHandler(java.lang.Object newHandler, int type) allows external helper classes to be added to JPedal to alter default functionality - not part of the API and should be used in conjunction with IDRsolutions only if Options.FormsActionHandler is the type then the newHandler should be of the form org.jpedal.objects.acroforms.ActionHandler
static void	addFontFile(java.lang.String currentFont, java.lang.String fontPath) method to add a single file to the PDF renderer
void	addImage(java.awt.image.BufferedImage img) used to display non-PDF files
boolean	addSubstituteFonts(java.lang.String fontPath, boolean enforceMapping) This routine allows the user to add truetype, type1 or type1C fonts which will be used to disalay the fonts in PDF rendering and substitution as if the fonts were embedded in the PDF This is very useful for clients looking to keep down the size of PDFs transmitted and control display quality - Thanks to Peter for the idea/code - How to set it up - JPedal will look for the existence of the directory fontPath (ie com/myCompany/Fonts) - If this exists, Jpedal will look for 3 possible directories (tt,t1c,t1) and make a note of any fonts if these directories exist - When fonts are resolved, this option will be tested first and if a font if found, it will be used to display the font (the effect will be the same as if the font was embedded) - If the enforceMapping is true, JPedal assumes there must be a match and will throw a PdfFontException - Otherwise Jpedal will look in the java font path for a match or approximate with Lucida - The Format is defined as follows: - fontname = filename Type1/Type1C Font names exclude any prefix so /OEGPNB+FGHeavyItalic is resolved to FGHeavyItalic - Each font have the same name as the font it replaces (so Arial will require a font file such as Arial.ttf) and it must be unique (there cannot be an Arial font in each sub-directory) - So to use this functionality, place the fonts in a jar or add to the JPedal jar and call this method after instancing PdfDecoder - JPedal will do the rest

void	setCenterOnScaling(boolean center)
static void	setDebugPrint(boolean newDebugPrint) provides details on printing to enable debugging info for IDRsolutions
static void	setDefaultDisplayFont(java.lang.String fontName) set the font used for default from Java fonts on system - Java fonts are case sensitive, but JPedal resolves this internally, so you could use Webdings, webdings or webDings for Java font Webdings - checks if it is a valid Java font (otherwise it will default to Lucida anyway)

void	setExtractionMode(int mode, int imageDpi, float scaling) Please do not use for general usage.
static java.lang.String	setFontDirs(java.lang.String[] fontDirs) takes a String[] of font directories and adds to substitution - Can just be called for each JVM - Should be called before file opened - this offers an alternative to the call -DFontDirs - Passing a null value flushes all settings
static void	setFontReplacements(PdfDecoder decode_pdf) set up our font replacement values
static void	setFontSubstitutionMode(int mode) set mode to use when substituting fonts (default is to use Filename (ie arial.ttf) Options are SUBSTITUTE_* values from PdfDecoder

void	setPageParameters(float scaling, int pageNumber, int newRotation) calls setPageParameters(scaling,pageNumber) after setting rotation to draw page
void	setPagePrintRange(int start, int end) set page range (inclusive) - If end is less than start it will print them backwards (invalid range will throw PdfException)
void	setPagePrintRange(javax.print.attribute.SetOfIntegerSyntax range) set inclusive range to print (see SilentPrint.java and SimpleViewer.java for sample print code (invalid range will throw PdfException) can take values such as new PageRanges("3,5,7-9,15");
void	setPDF(boolean isPDf)
void	setPrintAutoRotateAndCenter(boolean value) set print mode (Matches Abodes Auto Print and rotate output
void	setPrintCurrentView(boolean value)

void	setPrintPageMode(int mode) allow user to select only odd or even pages to print
void	setRenderMode(int mode) set render mode to state what is displayed onscreen (ie RENDERTEXT,RENDERIMAGES) - only generally required if you do not wish to show all objects on screen (default is all).
void	setStatusBarObject(StatusBar statusBar) set status bar to use when decoding a page - StatusBar provides a GUI object to display progress and messages.
void	setStreamCacheSize(int size) allows user to cache large objects to disk to avoid memory issues, setting minimum size in bytes (of uncompressed stream) above which object will be stored on disk if possible (default is -1 bytes which is all objects stored in memory) - Must be set before file opened.
static void	setSubstitutedFontAliases(java.lang.String fontFileName, java.lang.String[] aliases) allows a number of fonts to be mapped onto an actual font and provides a way around slightly differing font naming when substituting fonts - So if arialMT existed on the target machine and the PDF contained arial and helvetica (which you wished to replace with arialmt), you would use the following code - String[] aliases={"arial","helvetica"}; currentPdfDecoder.setSubstitutedFontAliases("arialmt",aliases); - comparison is case-insensitive and file type/ending should not be included - For use in conjunction with -Dorg.jpedal.fontdirs options which allows user to pass a set of comma separated directories with Truetype fonts (directories do not need to exist so can be multi-platform setting)
void	setTextPrint(int textPrint) tells program to try and use Java's font printing if possible as work around for issue with PCL printing - values are PdfDecoder.TEXTGLYPHPRINT (use Java to rasterize font if available) PdfDecoder.TEXTSTRINGPRINT( print as text not raster - fastest option) PdfDecoder.NOTEXTPRINT (default - highest quality)
void	setThumbnailsDrawing(boolean b) initialise display hotspots and save global values public void createPageHostspots(String[] annotationTypes, String string) { if(showAnnotations) return; if(displayHotspots==null || specialMode==SpecialOptions.NONE || specialMode==SpecialOptions.SINGLE_PAGE) displayHotspots = new Hotspots(annotationTypes, string); printHotspots = new Hotspots(annotationTypes, string); }/
void	setupPage(org.jpedal.parser.PdfStreamDecoder current, boolean alwaysCheck) initialise OC Content and other items before Page decoded but after Resources read
java.awt.geom.AffineTransform	setViewableArea(java.awt.Rectangle viewport) allows the user to create a viewport within the displayed page, the aspect ratio is keep for the PDF page Passing in a null value is the same as calling resetViewableArea() The viewport works from the bottom left of the PDF page The general formula is (leftMargin, bottomMargin, pdfWidth-leftMargin-rightMargin, pdfHeight-bottomMargin-topMargin) NOT RECOMMENDED FOR GENERAL USE (this has been added for a specific client and we have found it can be unpredictable on some PDF files).
void	showImageableArea() show the imageable area in printout for debugging purposes
void	stopPrinting() ask JPedal to stop printing a page
void	unsetScaling()
void	updatePageNumberDisplayed(int page) used by Javascript to update page number
void	useHiResScreenDisplay(boolean value) uses hires images to create a higher quality display - downside is it is slower and uses more memory (default is false).- Does nothing in OS version
void	useLogicalPrintOffset(int pagesPrinted) If you are printing PDFs using JPedal in your custom code, you may find pages missing, because JPedal does not know about these additional pages.
static void	useTextExtraction() XML extraction is the default - pure text extraction is much faster
static void	useXMLExtraction() XML extraction is the default - pure text extraction is much faster
void	waitForDecodingToFinish() wait for decoding to finish

                                             java.lang.String[] aliases)

allows a number of fonts to be mapped onto an actual font and provides a way around slightly differing font naming when substituting fonts - So if arialMT existed on the target machine and the PDF contained arial and helvetica (which you wished to replace with arialmt), you would use the following code -

String[] aliases={"arial","helvetica"}; currentPdfDecoder.setSubstitutedFontAliases("arialmt",aliases); -

comparison is case-insensitive and file type/ending should not be included - For use in conjunction with -Dorg.jpedal.fontdirs options which allows user to pass a set of comma separated directories with Truetype fonts (directories do not need to exist so can be multi-platform setting)

resetViewableArea

allows the user to create a viewport within the displayed page, the aspect ratio is keep for the PDF page

Passing in a null value is the same as calling resetViewableArea()

The viewport works from the bottom left of the PDF page
The general formula is
(leftMargin,
bottomMargin,
pdfWidth-leftMargin-rightMargin,
pdfHeight-bottomMargin-topMargin)

NOT RECOMMENDED FOR GENERAL USE (this has been added for a specific client and we have found it can be unpredictable on some PDF files).

The viewport will not be incorporated in printing

addSubstituteFonts

public boolean addSubstituteFonts(java.lang.String fontPath,
                                  boolean enforceMapping)

This routine allows the user to add truetype, type1 or type1C fonts which will be used to disalay the fonts in PDF rendering and substitution as if the fonts were embedded in the PDF
This is very useful for clients looking to keep down the size of PDFs transmitted and control display quality -

Thanks to Peter for the idea/code -

How to set it up -

JPedal will look for the existence of the directory fontPath (ie com/myCompany/Fonts) -

If this exists, Jpedal will look for 3 possible directories (tt,t1c,t1) and make a note of any fonts if these directories exist -

When fonts are resolved, this option will be tested first and if a font if found, it will be used to display the font (the effect will be the same as if the font was embedded) -

If the enforceMapping is true, JPedal assumes there must be a match and will throw a PdfFontException -

Otherwise Jpedal will look in the java font path for a match or approximate with Lucida -

The Format is defined as follows: -

fontname = filename

Type1/Type1C Font names exclude any prefix so /OEGPNB+FGHeavyItalic is resolved to FGHeavyItalic -

Each font have the same name as the font it replaces (so Arial will require a font file such as Arial.ttf) and it must be unique (there cannot be an Arial font in each sub-directory) -

So to use this functionality, place the fonts in a jar or add to the JPedal jar and call this method after instancing PdfDecoder - JPedal will do the rest

Parameters:

fontPath - - root directory for fonts

enforceMapping - - tell JPedal if all fonts should be in this directory

Returns:

flag (true if fonts added)
