PdfWidget

A nascent PDF view written based on Qt

Its very few features are

• Two render backends: MuPdf and Poppler
• Encryption support
• Zoom in and Zoom out (10% to 400%)

Qt4 and Qt5 builds are supported

Notes for compiling - linux:

• Download the sources
  • Git: git clone https://gitlab.com/marcusbritanicus/PdfWidget PdfWidget-master
  • Tar: wget https://gitlab.com/marcusbritanicus/PdfWidget/archive/master.tar.gz && tar -xf master.tar.gz
• Enter PdfWidget-master
• Open the terminal and type: qmake && make

Because there are a lot of versions of mupdf out there and some of the older versions have now-outdated function names, mupdf source in included in the build tree. The MuPDF source is picked from Debian/Sid (Source Version 1.13.0+ds1-2).

Because Noto, Droid and Hangul fonts bloat the library size to 45 MiB, I have removed them from the build tree. We also disable them using the flags -DNOCJK -DTOFU. To disable gl, we use HAVE_GLUT=np and use -fPIC so that we can link it with other shared objects. Though the source is nearly 11 MiB in size the library is ~8 MiB and the libpdfwidget.so will be after linking to mupdf ~3 MiB which is a decent size.

Known issues

• In the example implementation, changing the zoom causes the document to scroll to page 1.
• Changing the zoom in the example implementation causes my system to freeze up at times.
