Manipulate PDF Files On the Fly

Aspose.PDF for C++ is a good choice for modifying or manipulating existing PDF files within your applications. This library allows you to open or load PDF file, extract pages, insert pages at a particular location in the file or create N-up's (number of pages over single page) and booklets.

Convert PDF to JPG & Other Image Formats

Aspose.PDF for C++ allows you to render and transform each page of a PDF file into conventional image formats such as BMP, JPG & PNG, with the highest possible fidelity. Other than images, one can easily save PDF to DOC and DOCX formats.

Save PDF pages in JPG format - C++

// instantiate PdfConverter
auto converter = MakeObject<PdfConverter>();
// load an existing PDF document
converter->BindPdf(dir + u"template.pdf");
// convert PDF pages to images
int32_t imageCount = 1;
while (converter->HasNextImage()) 
    // save each page in JPG format
    converter->GetNextImage(dir + imageCount + u".jpg", System::Drawing::Imaging::ImageFormat::get_Jpeg(), 800, 1000);

Form Field Processing

Aspose.PDF for C++ offers the capabilities to add form fields to the PDF document, that is; you can dynamically generate form fields in PDF documents. Just order the position of the form fields as per a table or by custom positioning, and the form fields will be placed in the exact position every time.

Format PDF Contents on Most Granular Level
