Add Bookmarks to PDF using iTextSharp -


i have big pdf file , want copy pages new pdf file using itextsharp. works fine following code.

dim sourcefullfilepathandname string = "src.pdf" dim outputfullfilepathandname string = "cpy.pdf" dim pagefirst integer = 5 dim pagelast integer = 10  using rdr itextsharp.text.pdf.pdfreader = new itextsharp.text.pdf.pdfreader(sourcefullfilepathandname)     dim docsrc new itextsharp.text.document(rdr.getpagesizewithrotation(1))     using fs = new system.io.filestream(outputfullfilepathandname, system.io.filemode.create)         dim copy new itextsharp.text.pdf.pdfcopy(docsrc, fs)         docsrc.open()         dim bookmarks = new list(of dictionary(of string, object))() 'new arraylist() '// changed         pagenumber integer = pagefirst pagelast             dim ip = copy.getimportedpage(rdr, pagenumber)              if pagenumber = pagefirst '// changed                 dim h = ip.height '// changed                 dim test = new dictionary(of string, object) 'new hashtable() '// changed                 test.add("action", "goto") '// changed                 test.add("title", "page1 0 h 0") '// changed                 test.add("page", "1 xyz 0 " & h.tostring & " 0") '// changed                 bookmarks.add(test) '// changed             end if '// changed              copy.addpage(ip)         next         copy.outlines = bookmarks '// changed - got exception here!         docsrc.close()     end using     rdr.close() end using

but can not find out how add bookmark each new page. have found samples bookmark specific page using itextsharp 4.1.6 not solve problem.

update: added code of how tried create bookmarks marked '// changed btw. using itextsharp v5.4.4. getting following exception: unable cast object of type 'system.collections.arraylist' type 'system.collections.generic.ilist1[system.collections.generic.dictionary2[system.string,system.object]]'. changed again using list of dictionary instead of hashtable. not getting error getting no bookmarks.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
