Hi,

Integrated the debunu pdf library with my asp.net application. . I want to display the pdf file in the web application. I created annotation in the pdf file and trying to display the same pdf file using asp.net application. But the newly created annotations are not displaying in the pdf while displaying.

here my sample code is given below

//unlock the key

QP.UnlockKey("pdf key");

//load the pdf file

QP.LoadFromFile(filepath, "");

//file merge with previous file if any

QP.MergeFileList("old filename","new filename");

QP.AddNoteAnnotation(200, 200, 2, 200, 100, 50, 50, "annotation1", "demo annotation ", 0.1, 0.2, 0.4, 0);

QP.SaveToFile(filepath);

//again loading the same file to preview the annotations and bind to the object tag in the web //application. But no able to view the annotation

QP.LoadFromFile(filepath, "");

Need suggestions

regards,

Dhana

Hi Dhana!

I think after save you have to start a new instance and a new load to see the new annotation.

I have exactly the same problem, impossible to load a file with that size after doing a MergeFileFast. I have tried creating a new instance, but it doesn't works.

You do realize MergeFileList merges files on disk don't you. So if you are expecting the annotation in the merged file, then you have to load it into memory after merging and then add the annotation.
