Remove rectangle annotation

[KarlTH]

Hello Support-Team,

how can I remove a rectangle annotation or other annotations by name? Did not find anything in the documentation.
An example (pseudocode) will be great!

Code: Select all

'Get annot name
AxPDFXViewCtrl.GetProperty(e.name + ".Name", oDataOut)
strAnnotName = DirectCast(oDataOut, String)

Thanks,

Karl

Hi Karl,

You would need to use JS (RunJavaScript() method) for this.
e.g.: Remove all "FreeText" annotations on page 0.

Code: Select all

var annots = this.getAnnots({ nPage:0 }); 
for (var i = 0; i < annots.length; i++) 
if (annots[i].type == "FreeText") annots[i].destroy();

Hello Stefan,

I was afraid you will say that. JavaScript
I will try it and let you know if I was successfull!


THANK YOU

Hello Stefan,

I did it but JavaScript debugging is catastrophic and here is my code in VB .NET:

Code: Select all

Private Sub AxPDFXViewCtrl_OnEvent(sender As Object, e As AxPDFXCviewAxLib._IPDFXCviewEvents_OnEventEvent) Handles AxPDFXViewCtrl.OnEvent
                AxPDFXViewCtrl.GetProperty(e.name + ".Temp", oDataOut)
                iAnnotHasBeenCreated = DirectCast(oDataOut, Integer)

                If iAnnotHasBeenCreated = 0 Then '// (isTemp != 0) - the creation of annot isn't finished

                    AxPDFXViewCtrl.GetProperty(e.name + ".Name", oDataOut)
                    strAnnotName = DirectCast(oDataOut, String)

                    strJavaCmd = "var annots = this.getAnnots({ nPage:0 });" + Environment.NewLine
                    strJavaCmd += "for (var i = 0; i < annots.length; i++){" + Environment.NewLine
                    strJavaCmd += "if (annots[i].name == """ + strAnnotName + """) annots[i].destroy();" + Environment.NewLine
                    ' ONLY FOR DEBUGGING - strJavaCmd += "console.println(annots[i].name);" + Environment.NewLine
                    strJavaCmd += "}"

                    AxPDFXViewCtrl.RunJavaScript(strJavaCmd)
                End If
End Sub

Would be nice if you include a "RemoveAnnot" method in your API in one of the next releases.


Thank you so much

Hi Karl,

Glad that you made it work, and thanks for sharing your code! Hope it would be useful to other developers as well.

As for your request for a new method - I am not going to make any promises as there's already a way to achieve that with your "beloved" JS

Regards,
Stefan

Hi Stefan,

sounds good!
Now it is working but would be nice if I can replace this lines of Java code at the next Refactoring.


Thank you so much
