Error Digital Signature C# Acrobat Sdk

Hi.
I am creating an application to sign a pdf from c #.
I am currently having the following problem:

 

System.Runtime.InteropServices.COMException: 'Nombre desconocido. (Excepción de HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME))'

 

This is the code:

 

            Type AcrobatCAcroAppType;

            AcrobatCAcroAppType = Type.GetTypeFromProgID("AcroExch.app");

            Acrobat.CAcroApp gapp = (Acrobat.CAcroApp)Activator.CreateInstance(AcrobatCAcroAppType);

 

            Type AcrobatPDDocType;

            AcrobatPDDocType = Type.GetTypeFromProgID("AcroExch.PDDoc");

            Acrobat.CAcroPDDoc gpddoc = (Acrobat.CAcroPDDoc)Activator.CreateInstance(AcrobatPDDocType);

 

            object jso;

 

            if (gpddoc.Open("C:\\Users\\tmuñoz\\Desktop\\PDFs Para firmar\\Thuban-Nivel 2.pdf"))

            {

                jso = gpddoc.GetJSObject();

                object[] param = new object[1];

 

                param[0] = "C:\\Users\\tmuñoz\\Desktop\\ThomasMuñoz.pfx";

 

                object con = jso.GetType().InvokeMember("SetUserDigitalIDPath",

                BindingFlags.InvokeMethod, null, jso, param);

 

                param[0] = "testpassword";

                con = jso.GetType().InvokeMember("SetUserPassword",

                BindingFlags.InvokeMethod, null, jso, param);

                param[0] = jso;

 

                con = jso.GetType().InvokeMember("AddSignature",

                BindingFlags.InvokeMethod, null, jso, param);

            }

 

 

I think the error comes from not finding these functions in the JSO object.
From what I understand these are the sdkAddSignature file.
So I guess I should integrate it into the C # project, but I do not know how to do it.

AvDoc FindText returning to first page.

Hi,

 

I am attempting to implement AVDoc.FindText in an excel VBA script to find and highlight all instances of a search term in a document.  Here is the code I have:

 

Dim AcroApp, AcroAVDoc

    Dim gPDFPath, bReset, nCount

    gPDFPath = "PATH TO FILE"

    ' ** Initialize Acrobat by creating App object

    Set AcroApp = CreateObject("AcroExch.App")

    ' ** show Acrobat

    Call AcroApp.Show

    ' ** Set AVDoc object

    Set AcroAVDoc = CreateObject("AcroExch.AVDoc")

    ' ** open the PDF

    If AcroAVDoc.Open(gPDFPath, "") Then

    Call AcroAVDoc.BringToFront

    bReset = True: nCount = 0

    Do While AcroAVDoc.FindText("Text to Find", True, True, bReset)

         bReset = False: nCount = nCount + 1

    Loop

...

End Sub

 

But the problem is that the Do While Loop does not seem to resolve itself.  Once the FindText function finds the last instance of text in the document, it then finds the next instance, on Page one.  This of course causes that while loop to never terminate.

 

Anyone know what my issue could be, am I interpreting incorrectly how BReset should be working?

Adobe Acrobat SDK - List of Preference Items

I am working on creating a vba script (Excel) that will create a pdf and fix the width of the document to size of the view port.  I reviewed the Interapplication Communication API Reference documentation that list all of the methods and properties of the api.  I want to use the “SetPreferenceEx” method to set the  Zoom preference  to  a value of Fit Width.  In the instructions (page28), the method provides the data type and description of the parameters. The first parameter is expecting an application preference to be provided, for example, I would expect to be able to pass “Zoom” into this parameter.  I have been unsuccessful in trying to set this parameter.  The description says to go to the Acrobat and PDF Library API reference for a list of preference items.  I found the document here , the issue I am having is that document has over 6,000 pages and I have been unsuccessful in finding the  list of preferences.  I was hoping you could provide me with a cheat sheet or a page number of where I can locate the list.

Annotation Line Points Property WriteBack via IAC

I have posted this same issue on SO as well: javascript - Acrobat SDK IAC Modify Annotation Points Property - Stack Overflow

 

What I am trying to do at the moment was what I thought to be very trivial but is proving to be a confusing exercise. I simply wish to create a new annotation that is a line and set the points property to a specific value. When the object is initialized and set to "Line" type I can read the default points property, which it's value and datatype during debugging are as follows:

 

Points_DataType.png

 

So I tried a very simple assignment operation for testing by doing the following:

 

oLineAnnotation.points = New Object(1) {New Object(1) {100.0, 100.0}, New Object(1) {100.0, 100.0}}

 

This will throw the following exception: The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)).

 

I have tried other methods of assignment as well, i.e writing back to specific index in the property array:

 

oLineAnnotation.points(0) = New Double(1) {100, 100}

 

This doesn't throw an exception, but nothing is written back to the property. I've tried varying methods of writing back to the property but nothing has worked so far (not working being an exception is either thrown OR no exception is thrown but the points property doesn't change at all to the specified value after assignment)

Is it possible to use SDK JavaScript API  to sign (visible digital sign) a file in the browser on the client side?

 

in sample for js

 

 

functionAddSignature(doc)

    // if ACROSDK.sigDigitalIDPath is not spcified, ask for user input

    if(ACROSDK.sigDigitalIDPath == "UNKNOWN"){

        varcResponse = app.response({

                cTitle:"Digital Signature",

                cDefault:"/C/DrTest.pfx",

        if ( cResponse == null) {

            app.alert("No input.");

            return;

        }

        else

            SetUserDigitalIDPath(cResponse);

Problems accessing the app.newDoc () application

Good afternoon.
I am currently creating an application with Acrobat in .Net C #.
But I have problems accessing the app.newDoc () function.

 

 

c#:

            mApp = new AcroApp();       

            avDoc = new AcroAVDoc();   

          avDoc.Open("C:\\Users\\tmuñoz\\Desktop\\Thuban-Nivel 1.pdf", "");

            pdDoc = (CAcroPDDoc)avDoc.GetPDDoc();         

            object jso;        

            jso = pdDoc.GetJSObject();

            object[] param = new object[2];

object con = jso.GetType().InvokeMember("app.newDoc", BindingFlags.InvokeMethod, null, jso, param);

 

error:

System.Runtime.InteropServices.COMException: 'Nombre desconocido. (Excepción de HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME))'

 

 

 

On the other hand, when making a similar code in VB.net, it works for me.

 

VB.net:

 

        gPDDoc = CreateObject("AcroExch.PDDoc")

        gPDDoc.Open("C:\Users\tmuñoz\Desktop\PDFs Para firmar\Thuban-Nivel 2.pdf")

        Dim doc As Object

        jso = gPDDoc.GetJSObject()

        doc = jso.app.newDoc()

 

 

From what I understand, I am calling the add.newDoc function wrong from c #, if so, I would like you to tell me how it should be the correct way to call it

Create a DeviceN colorspace

Hi,

 

I need some help to create a DeviceN colorspace.

Thanks to the PDF Reference and this forum, I have written this function

 

// Creates a DeviceN colorspace

PDEColorSpacecreateDeviceN(PDDocpdDoc){

 

PDEColorSpacedeviceNColorSpace;

CosDoc    cosDocObj=PDDocGetCosDoc(pdDoc);

CosObj    colourSpaceCosObj=CosNewArray(cosDocObj,true,4);

 

// Names array

CosObj    namesCosObj=CosNewArray(cosDocObj,false,5);

CosArrayPut(namesCosObj,0,CosNewNameFromString(cosDocObj,false,"Cyan"));

CosArrayPut(namesCosObj,1,CosNewNameFromString(cosDocObj,false,"Magenta"));

CosArrayPut(namesCosObj,2,CosNewNameFromString(cosDocObj,false,"Yellow"));

CosArrayPut(namesCosObj,3,CosNewNameFromString(cosDocObj,false,"Black"));

CosArrayPut(namesCosObj,4,CosNewNameFromString(cosDocObj,false,"Blue"));

 

// Domain

CosObjcosDomainObj=CosNewArray(cosDocObj,false,10);

CosArrayPut(cosDomainObj,0,CosNewFloat(cosDocObj,false,(float)0.0));

CosArrayPut(cosDomainObj,1,CosNewFloat(cosDocObj,false,(float)1.0));

[…]

 

// Range

CosObjcosRangeObj=CosNewArray(cosDocObj,false,8);

CosArrayPut(cosRangeObj,0,CosNewFloat(cosDocObj,false,(float)0.0));

CosArrayPut(cosRangeObj,1,CosNewFloat(cosDocObj,false,(float)1.0));

[…]

 

// Function

//const char    *PostScriptFunc = "{ pop }";

constchar    *PostScriptFunc="{ 0.5 0.5 0.5 0.5 }";

ASInt32Size=strlen(PostScriptFunc);

 

CosObjcosFunctDict=CosNewDict(cosDocObj,false,4);

CosDictPut(cosFunctDict,ASAtomFromString("FunctionType"),CosNewInteger(cosDocObj,false,4));

CosDictPut(cosFunctDict,ASAtomFromString("Domain"),cosDomainObj);

CosDictPut(cosFunctDict,ASAtomFromString("Range"),cosRangeObj);

CosDictPut(cosFunctDict,ASAtomFromString("Length"),CosNewInteger(cosDocObj,true,Size));

 

ASStmStream=ASMemStmRdOpen(PostScriptFunc,Size);

CosObjPostScriptFuncStreamObj=CosNewStream(cosDocObj,true,Stream,0,true,cosFunctDict,CosNewNull(),-1);

ASStmClose(Stream);

 

CosArrayPut(colourSpaceCosObj,0,CosNewNameFromString(cosDocObj,false,"DeviceN"));

CosArrayPut(colourSpaceCosObj,1,namesCosObjP);

CosArrayPut(colourSpaceCosObj,2,CosNewNameFromString(cosDocObj,false,"DeviceCMYK"));

CosArrayPut(colourSpaceCosObj,3,PostScriptFuncStreamObj);

 

deviceNColorSpace=PDEColorSpaceCreateFromCosObj(&colourSpaceCosObj);

 

returndeviceNColorSpace;

}

 

According to an answer on a post of yokuju, I have tried to add the optional attributes by adding this part to the function

 

// Domain

CosObjcosDomainObj2=CosNewArray(cosDocObj,false,2);

CosArrayPut(cosDomainObj2,0,CosNewFloat(cosDocObj,false,(float)0.0));

CosArrayPut(cosDomainObj2,1,CosNewFloat(cosDocObj,false,(float)1.0));

 

// Range

CosObjcosRangeObj2=CosNewArray(cosDocObj,false,8);

CosArrayPut(cosRangeObj2,0,CosNewFloat(cosDocObj,false,(float)0.0));

CosArrayPut(cosRangeObj2,1,CosNewFloat(cosDocObj,false,(float)1.0));

[...]

 

// Function

constchar    *PostScriptFunc2="{ 1.0 1.0 0.0 0.0 }";

ASInt32Size2=strlen(PostScriptFunc2);

 

CosObjcosFunctDict2=CosNewDict(cosDocObj,false,4);

CosDictPut(cosFunctDict2,ASAtomFromString("FunctionType"),CosNewInteger(cosDocObj,false,4));

CosDictPut(cosFunctDict2,ASAtomFromString("Domain"),cosDomainObj2);

CosDictPut(cosFunctDict2,ASAtomFromString("Range"),cosRangeObj2);

CosDictPut(cosFunctDict2,ASAtomFromString("Length"),CosNewInteger(cosDocObj,true,Size2));

 

ASStmStream2=ASMemStmRdOpen(PostScriptFunc2,Size2);

CosObjPostScriptFuncStreamObj2=CosNewStream(cosDocObj,true,Stream2,0,true,cosFunctDict2,CosNewNull(),-1);

ASStmClose(Stream2);

 

CosObjcosBlueObj=CosNewArray(cosDocObj,false,4);

CosArrayPut(cosBlueObj,0,CosNewNameFromString(cosDocObj,false,"Separation"));

CosArrayPut(cosBlueObj,1,CosNewNameFromString(cosDocObj,false,"Blue"));

CosArrayPut(cosBlueObj,2,CosNewNameFromString(cosDocObj,false,"DeviceCMYK"));

CosArrayPut(cosBlueObj,3,PostScriptFuncStreamObj2);

 

// Colorants sictionary

CosObjcosColorantsDict=CosNewDict(cosDocObj,false,1);

CosDictPut(cosFunctDict2,ASAtomFromString("Blue"),cosBlueObj);

 

CosArrayPut(colourSpaceCosObjP,4,PostScriptFuncStreamObj2);

 

Even with the additionnal attribute, I still have the same issue as Sam BSW. If I use just one time this colorspace, the current page will be empty. In the PDF file instead of having something like

 

<</Contents 3 0 R/CropBox[0.0 0.0 612.0 842.4]/MediaBox[0.0 0.0 612.0 842.4]/Parent 162 0 R/Resources<</ColorSpace<</CS0 227 0 R/CS1 227 0 R>>/Font<</T1_0 12 0 R/ [...] /T1_9 29 0 R>>/ProcSet[/PDF/Text/ImageC]/XObject<</Im0 230 0 R>>>>/Rotate 0/Type/Page>>

 

for the page, I have simply

 

<</CropBox[0.0 0.0 612.0 842.4]/MediaBox[0.0 0.0 612.0 842.4]/Parent 162 0 R/Resources<<>>/Rotate 0/Type/Page>>

 

I am not a power user of the Adobe SDK so I am stuck here. I hope that someone can help me with my issue.

 

Thank you

Hi All,

 

We are trying to extract first page thumbnail from a pdf file . we are converting internally into image for first page and generating thumbnails . this process is taking too much time and giving performance issue .this is being done using java language .

 

is there any other API or toll we can use which will give better performance using java please suggest .

 

Our requirement - lots of pdf files are there with different size and size can be lead to max 30 MB file .

 

either the 1st page of pdf can be converted into image generate different size thumbnails or directly from pdf file to different thumb nail size .

 

either way is fine . please suggest .

Anyone know why Acrobat's update (2019.010.20019) broke my JS? Most of the code dates back to 9/X and have been updated for privilege and security changes (10.1.1) but now the global vars all are saved but then a couple of vars aren't retrieved from GlobData and those vars default to default settings. Anyone run into a similar experience? The only change was updating to 20019 from 20069.

We are facing issues of adding new tags manually or make the entire document accessible manually. We wanted to create a plugin which will fix or create accessible tags based upon the custom rule defined.
