\title Qt PDF
\brief Renders pages from PDF documents.
The Qt PDF module contains classes and functions for rendering
PDF documents. The \l QPdfDocument class loads a PDF document
and renders pages from it according to the options provided by
the \l QPdfDocumentRenderOptions class. The \l QPdfPageRenderer
class manages a queue that collects all render requests. The
\l QPdfPageNavigator class handles the navigation through a
PDF document. The \l QPdfSearchModel class searches for a string
and holds the search results. The QPdfBookmarkModel class holds the
table of contents, if present. The QPdfLinkModel holds information
about hyperlinks on a page. The \l QPdfView widget is a complete
PDF viewer, and the \l {PDF Viewer Example} shows how to use it.
For Qt Quick applications, three kinds of full-featured viewer
components are provided. \l PdfMultiPageView should be your
first choice for the most common user experience: flicking
through the pages in the entire document.
\l PdfScrollablePageView shows one page at a time, with scrolling;
and \l PdfPageView shows one full page at a time, without scrolling.
The full-featured viewer components are composed of lower-level
QML components that can be used separately if you need to write a
more customized PDF viewing application: \l PdfDocument,
\l PdfPageImage, \l PdfPageNavigator, \l PdfSelection,
\l PdfSearchModel, \l PdfLinkModel, and \l PdfBookmarkModel.
If you only need to render page images, without features such as
text selection, search and navigation, this module includes a
\l QImageIOHandler plugin that treats PDF as a scalable
\l {Qt Image Formats}{image format}, similar to \l {Qt SVG}{SVG}.
You can simply use \l Image, and set the
\l {Image::currentFrame}{currentFrame} property to the page index
that you wish to display. If the PDF file does not render its own
background, the image has a transparent background.
