The main qpageview module

This is a generic paged view widget.

Its main design goal is to display the pages of a PDF document, but it can display any set of images or pages, originating from different documents.

Every page is represented by a Page instance, which encompasses all logic for the document type, i.e. drawing etc.

Pages are managed by a PageLayout.

A PageLayout can be set to a View so the pages are displayed.

The images from a PDF, SVG of possibly other document are cached, and rendering is tile-based, to support zooming in at great detail. Also a magnifier is available, which by default pops up at Ctrl+click.

Because the qpageview is built on Qt, we use the Qt convention to have camelCase method names and CamelCase class names.

class View(parent=None, **kwds)

Bases: qpageview.link.LinkViewMixin, qpageview.highlight.HighlightViewMixin, qpageview.shadow.ShadowViewMixin, qpageview.util.LongMousePressMixin, qpageview.view.View

Paged view component based on view.View, with all enhancements.

loadPdf(filename, renderer=None)

Convenience function to create a Document with the specified PDF file.

The filename can also be a QByteArray or an already loaded popplerqt5.Poppler.Document instance.

loadSvgs(filenames, renderer=None)

Convenience function to create a Document with the specified SVG files.

Each SVG file is loaded in one Page. A filename can also be a QByteArray.

loadImages(filenames, renderer=None)

Convenience function to create a Document with images from files.

Each image is loaded in one Page. A filename can also be a QByteArray.

diffDocument(documents, renderer=None)

Convenience function to create a diff.DiffDocument from other documents.

The difference works best with documents that are similar and mostly black and white.
