HI All,

Is there a way to create an annotation (rectangle, line, circle, etc) and add it into the PDF file?
Further, is it able to set extract information of the annotation object?
The worst, any substitution?

sample:
12 0 obj<</Rect[104.741 687.906 227.585 743.509]/NM(PURK_SIGN-0000000020)/Subtype/PURK:SignStamp430C/F 68/M(D:20120808094218+08'00')/T(Signed by: dev rc. Date: 8/8/2012 9:42 AM)/PurkinjeMetaData<</USR.USR_ID/P/PATIENT.PATIENT_PROVINCE/Qu\233bec>>/Type/Annot/AP<</N 13 0 R>>>>
endobj

Thanks!

Here is a link to all of the Annotation functions available in Quick PDF Library.

AddNoteAnnotation

AddLink...

Then there are the Get and Set methods to read and write various properties.

Your PDF object below looks like part of a signature. Object 13 is missing would be required - It would a stream object that contains the drawing commands to render the signature.

QPL currently doesn't create signature appearance streams for annotations.

Thanks to AndrewC!
AndrewC you are correct, I just want to simulate a sign action, could be normal annotation, stamps annotation or real signature. I even tried DrawBox and DrawTextBox, but no way to put extra info.

I saw the Annotation functions and tried AddNoteAnnotation and AddTextMarkupAnnotation, they worked fine, so did GetAnnotIntProperty; but I do not know how to add a rectangle annotation and put some extra invisible data.

Actually the use case is:
1. user drags the mouse to select a rectangle area in the PDF reader
2. the system adds a rectangle annotation at the same position with several lines of visible info to describe the action, such as (Signed by: dev rc. Date: 8/8/2012 9:42 AM)
3. the system puts some other extra info for the annotation to snapshot the context, such as PurkinjeMetaData<</USR.USR_ID/P/PATIENT.PATIENT_PROVINCE/Qu\233bec>>

the sample I provided at the beginning was done with Acrobat, here is the object 13
13 0 obj<</Subtype/Form/Length 157/Filter/FlateDecode/Resources<</Font 14 0 R>>/Type/XObject/BBox[0 0 190 86]/FormType 1>>stream

endobj

Any good ideas?
