    You can use poppler as I show in this post: https://stackoverflow.com/a/52844509/6622587

    If you want me to help you develop some work then you can write to my email: e.yllanescucho@gmal.com.

      Let me add that for QML you'd need to wrap rendering into C++ backend, I am not aware of any direct method to use with QML (but then again, I am no expert in QML).

          @eyllanesc: Ok. Thank you for the example. I compiled and installed the plugin. But why is it "import org.docviewer.poppler 1.0"?
          This gives me the error "module "org.docviewer.poppler" is not installed".
          Maybe I should mention that I am cross compiling on Ubuntu my application for raspberry pi.

            Well, because you need to import Poppler stuff if you want to use it.
            "I compiled and installed the plugin" - did you cross-compiled it for your device or host machine?

              @jsulm: At the moment I am a little bit confused.
              I compiled and installed it directly on my raspberry.

                It needs to be in your sysroot. Did you resync your sysroot after installing on RPi?

                  @jsulm: Ah okay. Of course, I have to resync my sysroot. I resynced the folders /usr/local/include, /usr/local/lib and /usr/lib/arm-linux-gnueabihf/qt5 from raspberry to host.

                  Then I added this to my qmldir file:

                  module org.docviewer.poppler
                  PDFView 1.0 PDFView.qml
                  plugin popplerPlugin
                  typeinfo popplerPlugin.qmltypes
                  

                  But now I get the error message:

                  plugin "popplerPlugin" not found
                  

                  What is the reason for this error message?

                    @Melle_87 I'm not a QML expert.
                    Not sure you have to change qmldir.
                    When you installed Poppler on RPi - where was it installed?

                      @jsulm: I think on raspi it was installed in /usr/lib/arm-linux-gnueabihf/qt5/qml/org/docviewer/poppler. Because in this folder I find popplerPlugin.qmltypes.

                        You can follow the import process when setting environment variable QML_IMPORT_TRACE.
                        As written in documentation, QML import path is:

                        Additional import paths can be added through QQmlEngine::addImportPath() or the QML2_IMPORT_PATH environment variable. When running the qmlscene tool, you can also use the -I option to add an import path.

                        Take a look here ==> https://doc.qt.io/qt-5/qtqml-syntax-imports.html#qml-import-path

                        It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. (Sherlock Holmes)

                                Yes, I think so. But I would suggest you first to try out QML_IMPORT_TRACE to be aware why your plugin in not loaded.
                                Perhaps there are missing libs?

                                  @KroMignon: Thank for alle the tipps. I leave my qmldir file as it is and only set QML2_IMPORT_PATH = /usr/lib/arm-linux-gnueabihf/qt5/qml. Now the everything seems to be loaded correctly.
                                  But now I have a new problem. On start up I get a "Segmentation fault".
                                  I think the problem is that I compiled poppler with qmake of Qt 5.11.3. But actually I use Qt5.12.4. I have both Qt versions on the raspi. How can I explicitly use the qmake of Qt5.12.4 for compiling poppler?

                                    How can I explicitly use the qmake of Qt5.12.4 for compiling poppler?

                                    By calling the qmake from the Qt version you want to use (use absolute path to qmake).

                                      @jsulm: Hmmm... Okay. Unfortunately in Qt5.12.4 folder there is no qmake available ...

                                        Then this is not a valid Qt installation.
                                        How did you install it?

                                          @jsulm: It was not me who installed the Qt version ... So I have to ask. But is there a way to get the qmake of this version?
                                          Or maybe it would be easier to cross compile Poppler?
