Currently, I am using coldfusion 9 and I am trying to get information about annotations from within a PDF file. The problem is that there are two types of annotations: text and popup. I am using iText and I can get an annotation array that has 7 objects.
<cfset reader = CreateObject("java","com.lowagie.text.pdf.PdfReader").init(expandPath("test.pdf"))>
<cfset pageDict = reader.getPageN(1)>
<cfset pdfname = createObject("java","com.lowagie.text.pdf.PdfName")>
<cfset annots = pageDict.getAsArray(pdfname.ANNOTS)>
So now I see that I have 7 annotations ( I know one is text, and the other 6 are popup). At this point I want to loop through the annotation array and get the informartion
<cfset iterator = annots.listIterator()>
<cfset annot = reader.getPdfObject(iterator.next())>
<cfset content = reader.getPdfObject(annot.get(pdfname.CONTENTS))>
<cfif not isNull(content)>
Text Comment =#content# <!--- This works for the text comments --->
<!--- This happends to be the Popup contents, and where I get lost ---->
So in the part where I am trying to get the popup contents, I have tried <cfset x = reader.getPdfObject(annot.getAsDict(pdfname.popup))> This works, but I can't seem to extract the data. All I need is to get either the Subject or Name from the popup innotation as they are set to a set number of possibilities in our system. How do I extract the name or subject info drom the popup object?
Have you tried /Subj...?
cfset subjKey = createObject('java', 'com.lowagie.text.pdf.PdfName').init("Subj")
cfset subjText = annot.get(subjKey)
Thank you! I had been trying to get the subject off of the annot obj. I didn't realize that the I had to init Subj. Once I tried that I was able to do annot.get(subjKey).toString() and get the values I needed!
Thank you again!
The PdfName class defines a bunch of constants, like PdfName.Subject. But you can use init() for custom values when needed.
