C++ developers can easily load & merge EPUB files to PDF in just a few lines of code.
- Initialize a new Document, and run a loop for merging files
- In loop: add a new page to PDF document
- In loop: add EPUB file to new PDF page
- After the loop save the result
Here is an example that demonstrates how to merge EPUB to PDF in C++. Combine multiple documents into a single file with ease. If you are developing code in C++, this task can be simpler than it sounds. You can use fully qualified filenames for both EPUB reading and PDF writing. Check out this C++ example that show how to merge multiple documents of either the same or different file types into one file using C++
Merge EPUB files using C++ and save as PDF
Example C++: this sample code shows EPUB to PDF concatenation
Input file:
File not added
File not added
Output format:
Output file:
String pathSource1 = u"../../TestData/test.epub";
String pathSource2 = u"../../TestData/Second/test.epub";
auto opt1 = MakeObject<EpubLoadOptions>();
// use algorithm to prevent content to be truncated
opt1->PageSizeAdjustmentMode = Aspose::Pdf::LoadOptions::PageSizeAdjustmentModes::EnlargeRequiredViewportWidthAndDoConversionAgain;
// usage of margins area during conversion
opt1->MarginsAreaUsageMode = Aspose::Pdf::LoadOptions::MarginsAreaUsageModes::PutContentOnMarginAreaIfNecessary;
// epub files can be parsed and loaded as Aspose Document
System::SharedPtr<Document> firstDoc = MakeObject<Document>(pathSource1, opt1);
auto opt2 = MakeObject<EpubLoadOptions>();
// use algorithm to prevent content to be truncated
opt2->PageSizeAdjustmentMode = Aspose::Pdf::LoadOptions::PageSizeAdjustmentModes::EnlargeRequiredViewportWidthAndDoConversionAgain;
// usage of margins area during conversion
opt2->MarginsAreaUsageMode = Aspose::Pdf::LoadOptions::MarginsAreaUsageModes::PutContentOnMarginAreaIfNecessary;
auto secondDoc = MakeObject<Document>(pathSource2, opt2);
// create empty pdf document
auto outputDoc = MakeObject<Document>();
// set less memory usage with unload instead of fast performance
outputDoc->set_EnableObjectUnload(true);
for (auto const& page : firstDoc->get_Pages())
{
// add page from one document to another directly
outputDoc->get_Pages()->CopyPage(page);
}
for (auto const& page : secondDoc->get_Pages())
{
// add page from one document to another directly
outputDoc->get_Pages()->CopyPage(page);
}
// save result pdf to file
outputDoc->Save(u"Merger_epub_pdf.pdf", SaveFormat::Pdf);
