http://www.verypdf.com/app/advanced-pdf-tools/try-and-buy.html#buy-sdk

http://www.verypdf.com/pdfinfoeditor/pdftoolsdk.zip

The new version of pdftoolsdk.dll does support new options to show and hide PDF layers,

-s activelayer=0&&1
-s deactivelayer=0&&1
-s activelayer=0&&1 -s deactivelayer=photo&&text

you can use "&&" symbol to select more layers together.

The following is a C++ example to show and hide layers in PDF file,

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#include <time.h>

#include <io.h>

#include <sys/types.h>

#include <sys/stat.h>

#include <conio.h>

#include <ctype.h>

#include <windows.h>

 

/*

-s activelayer=0&&1

-s deactivelayer=0&&1

-s activelayer=0&&1 -s deactivelayer=photo&&text

*/

__declspec(dllexport) int WINAPI VeryPDF_PDFTools(LPCTSTR lpCommand);

 

void GetModulePath(char *out_path,char *in_name)

{

         char *p;

         GetModuleFileName(NULL,out_path,256);

         p =strrchr(out_path,'\\');

         p[1]=0;

         strcat(out_path,in_name);

}

 

void main()

{

         char szLayerPDF[_MAX_PATH];

         GetModulePath(szLayerPDF, "layers.pdf");

 

         char szOutputPDF1[_MAX_PATH];

         GetModulePath(szOutputPDF1, "_out1.pdf");

 

         char szOutputPDF2[_MAX_PATH];

         GetModulePath(szOutputPDF2, "_out2.pdf");

        

         char szOutputPDF3[_MAX_PATH];

         GetModulePath(szOutputPDF3, "_out3.pdf");

 

         int nRet = 0;

         char szCommandLine[1024];

         char *lpLicenseKey = "XXXXXXXXXXXXXX";

 

         sprintf(szCommandLine,"pdftools -$ \"%s\" -s \"activelayer=0&&1\" -s \"deactivelayer=photo&&text\" -i \"%s\" -o \"%s\"", lpLicenseKey, szLayerPDF, szOutputPDF1);

         nRet = VeryPDF_PDFTools(szCommandLine);

         printf("%s\nReturn value is: %d\n\n", szCommandLine, nRet);

 

         sprintf(szCommandLine,"pdftools -$ \"%s\" -s \"activelayer=border\" -s \"deactivelayer=photo&&text\" -i \"%s\" -o \"%s\"", lpLicenseKey, szLayerPDF, szOutputPDF2);

         nRet = VeryPDF_PDFTools(szCommandLine);

         printf("%s\nReturn value is: %d\n\n", szCommandLine, nRet);

        

         sprintf(szCommandLine,"pdftools -$ \"%s\" -s \"activelayer=text&&photo\" -s \"deactivelayer=0&&1\" -i \"%s\" -o \"%s\"", lpLicenseKey, szLayerPDF, szOutputPDF3);

         nRet = VeryPDF_PDFTools(szCommandLine);

         printf("%s\nReturn value is: %d\n\n", szCommandLine, nRet);

}

 

The following is a VBScript code to show and hide layers in PDF file,

Dim nRet, strCmd

 

Set fso = CreateObject("Scripting.FileSystemObject")

strFolder = fso.GetParentFolderName(wscript.ScriptFullName)

strFolder = strFolder & "\"

 

strCmd = "pdftools -s ""activelayer=0&&1"" -s ""deactivelayer=photo&&text"""

strCmd = strCmd & " -$ XXXXXXXXXXXXXXX"

strCmd = strCmd & " -i """ & strFolder & "layers.pdf" & """"

strCmd = strCmd & " -o """ & strFolder & "_layers-com-out.pdf" & """"

 

MsgBox strCmd

Set PDFToolsCOM = CreateObject("PDFTools.PDFToolsCOM")

nRet = PDFToolsCOM.com_VeryPDF_PDFTools(strCmd)

Set PDFToolsCOM = Nothing

 


The following is original PDF file which contain more layers,
