C++: Insert or Remove Page Breaks in Word

Remove Page Breaks in a Word Document in C++

Some mistakenly added page breaks can mess up the structure of your entire document, so it's quite necessary to remove them. The following are the steps to remove page breaks in a Word document.

Create a Document instance.
Load a Word document using Document->LoadFromFile() method.
Traverse through each paragraph in the first section, and then traverse through each child object of a paragraph.
Determine whether the child object type is a page break. If yes, remove the page break from the paragraph using Paragraph->GetChildObjects()->Remove() method.
Save the result document using Document->SaveToFile() method.

#include "Spire.Doc.o.h"

using namespace Spire::Doc;

int main() {
 //Specify input file path and name
 std::wstring input_path = L"Data\\";
 std::wstring inputFile = input_path + L"InsertPageBreak.docx";

 //Specify output file path and name
 std::wstring output_path = L"Output\\";
 std::wstring outputFile = output_path + L"RemovePageBreaks.docx";

 //Create a Document instance
 intrusive_ptr<Document> document = new Document();

 //Load a Word document from disk
 document->LoadFromFile(inputFile.c_str());

 //Traverse through each paragraph in the first section of the document
 for (int j = 0; j < document->GetSections()->GetItemInSectionCollection(0)->GetParagraphs()->GetCount(); j++)
 {
  intrusive_ptr<Paragraph> p = document->GetSections()->GetItemInSectionCollection(0)->GetParagraphs()->GetItemInParagraphCollection(j);

  //Traverse through each child object of a paragraph
  for (int i = 0; i < p->GetChildObjects()->GetCount(); i++)
  {
   intrusive_ptr <DocumentObject> obj = p->GetChildObjects()->GetItem(i);

   //Determine whether the child object type is a page break
   if (Object::CheckType<Break>(obj) && (Object::Dynamic_cast<Break>(obj))->GetBreakType() == BreakType::PageBreak)
   {
    //Remove the page break from the paragraph
    p->GetChildObjects()->Remove(obj);
   }
  }
 }

 //Save the result document
 document->SaveToFile(outputFile.c_str(), FileFormat::Docx2013);
 document->Close();
}

Extract Images from a Word Document in C++

For a Word document with a lot of images, manually saving these images one by one is quite time-consuming. Below are steps to extract all images at once using Spire.Doc for C++.

Load a sample Word document using Document->LoadFromFile() method.

Append the document to the end of the deque, and then create a vector of images list.
Traverse through all child objects of the document.
Determine whether the object type is picture. If yes, get each image using DocPicture->GetImage() method and add it to the list.
Save the extracted images out of the document in a specified output file path.

#include "Spire.Doc.o.h"
#include <deque>

using namespace Spire::Doc;

int main() {
 //Specify input file path and name
 std::wstring data_path = L"Data\\";
 std::wstring inputFile = data_path + L"input.docx";

 //Specify output file path and name
 std::wstring outputPath = L"Output\\";
 std::wstring outputFile = outputPath + L"ExtractImage/";

 //Load a sample Word document
 intrusive_ptr<Document> document = new Document();
 document->LoadFromFile(inputFile.c_str());

 //Append the document to the end of the deque
 std::deque<intrusive_ptr<ICompositeObject>> nodes;
 nodes.push_back(document);

 //Create a vector of images list
 std::vector<std::vector<byte>> images;

 //Traverse through all child objects of the document
 while (nodes.size() > 0)
 {
  intrusive_ptr<ICompositeObject> node = nodes.front();
  nodes.pop_front();
  for (int i = 0; i < node->GetChildObjects()->GetCount(); i++)
  {
   intrusive_ptr<IDocumentObject> child = node->GetChildObjects()->GetItem(i);
   if (child->GetDocumentObjectType() == DocumentObjectType::Picture)
   {
    intrusive_ptr<DocPicture> picture = Object::Dynamic_cast<DocPicture>(child);
    std::vector<byte> imageByte = picture->GetImageBytes();
    images.push_back(imageByte);
   }
   else if (Object::CheckType<ICompositeObject>(child))
   {
    nodes.push_back(boost::dynamic_pointer_cast<ICompositeObject>(child));
   }
  }
 }
 //Save the images out of the document
 for (size_t i = 0; i < images.size(); i++)
 {
  std::wstring fileName = L"Image-" + std::to_wstring(i) + L".png";
  std::ofstream outFile(fileName, std::ios::binary);
  if (outFile.is_open())
  {
   outFile.write(reinterpret_cast<const char*>(images[i].data()), images[i].size());
   outFile.close();
  }
 }
 document->Close();
}
