Extremely basic plugin for rendering PDF files using Poppler in QML apps.

Supported features:

• Rendering PDF pages in any resolution (controlled by Image item sourceSize property)
• Parsing document links
• Document search

Based on discontinued poppler-qml-plugin by Canonical (GPL v3).

• Qt 5.11+
• Poppler-Qt5 0.31+
• Qt Quick Controls 2 (only for an example app)

qmake
make
make install

See example app sources in example directory.

Set POPPLERPLUGIN_DEBUG environment variable to 1 before starting application.

PDFView is pure QML component, utilizing Poppler native component from this plugin. It serves as a good start when you just need to display PDF document.

If it doesn't suit your purposes very well, take a look at it source and implement the view more suiting your target functionality.

This component is an extended ListView (with custom delegate and some other logic inside), so you can simply add scroll bar or customize page spacing from your application code.

import org.docviewer.poppler 1.0

...

PDFView {
  anchors.fill: parent
  path: "path_to_file.pdf"
}

Local file path to open.

Zoom level. Defaults to 1.0, at this component show document at 72 dpi.

Number of pages in opened document

Number of page currently shown in a center of viewport, starting with 0.

Color of found search term highlight. Defaults to Qt.rgba(1, 1, .2, .4).

Starts search for a passed substring. When found, scrolls view to show the string found. Repeating calls to this method passing the same string will result in moving to next occurance of the text.

ListView {
  anchors.fill: parent
  model: poppler.pages
  delegate: Image {
    cache: false
    fillMode: Image.Pad

    source: modelData.image
    sourceSize.width: modelData.size.width

    width: sourceSize.width
    height: sourceSize.height
  }
}

Local file path to open.

List of document pages.

Each page contains several properties

• image - url of image to be used in Image QML element. Page image will be rendered by image provider based on Image sourceSize property
• size - document page size in points (i.e. 1/72th of inch). Could be used to determine Image element size before asyncronous rendering is finished
• links - array of page links
  • rect - active link rectangle as a proportion of page size (width being .5 means 50% of page width etc.)
  • destination - link destination
    • page - page index
    • top - top coordinate of link destination (relative to page size, same as rect property)
    • left - left coordinate of link destination (relative to page size)

Returns list of text highlight rectangles for the page. May return empty array.
