errorcorrection).Recommendederrorcorrectionlevelsarebetweenlevel2and5,buttheoptimal
valuedependsontheamountofdata,printingqualityofthePDF417symbolanddecodingcapabilities
ofthescanner.
Nr. of Columns
Thenumberofdatacolumnscanvaryfrom3to30.
Nr. of Rows
APDF417barcodecanhaveanywherefrom3to90rows.
Bar height
Definestheheightofthebarsforasinglerowmeasuredinpixelsdrawn.
Compact
CheckthisoptiontouseCompactPDF417insteadofthePDF417barcode.Thisshortenedformofthe
PDF417barcodeisusefulwherethespaceforthesymbolisrestricted.
Scale
Definesifandhowtherenderedbarcodeisscaledinrelationtotheparentelement:
l
None:Thebarcodeisrenderedbasedonthemodulewidth.
l
Fit to box:Thebarcodeisstretchedtofittheparentboxinbothwidthandheight.
l
Proportionally:Thebarcodeisstretcheduptowhereitfitseitherthewidthorheightofthepar-
entbox,whicheverrequiresthelessstretching.
Tilde processing
Checkthisoptiontoprocesstilde(~)charactersinthedataasspecialcharacters.(SeetheJava4less
BarcodesGuidetolearnwhatthetildecharactercanbeusedfor.)
Thetildeisexpectedtobefollowedbythe'd'characterand3digitsrepresentinganASCIIcharacter:
~dNNN.Forexample,~d013representsacarriagereturn.
Notethatwiththisoptionchecked,anytildethatneedstobeincludedintheoutputmustbeescapedby
addinganothertilde:~~.
Color
TheColorgroupallowsyoutochooseadifferentBarcodecolor(insteadofblack)andBackground
color(insteadofwhite),bytypingahexadecimalcolorvalue(seeforexamplew3school'scolorpicker).
