PhotoQt is a fast and highly configurable image viewer with a simple and nice interface.

• Qt >= 5.3
• CMake (needed for building PhotoQt)

Make sure that you have the needed Qt modules installed:
QtQuick, QtQuick.Controls, QtQuick.Controls.Styles, QtQuick.Dialogs, QtQuick.Layouts, QtQuick.Window, QtQml.Models, Qt.labs.folderlistmodel, QtGraphicalEffects, QtMultimedia.
Dependencies, that are needed by default, but can be disabled via CMake

• Exiv2
• GraphicsMagick
• LibRaw

On some systems you also need the *-dev package for compiling (e.g. exiv2-dev - names can vary slightly depending on your distribution). These files usually can be uninstalled again after compilation is done.

Even though GraphicsMagick initially started as a fork of ImageMagick (in 2002), trying to build PhotoQt with ImageMagick wont work!

• XCFtools - https://github.com/j-jorge/xcftools
• libqpsd - https://github.com/Code-ReaQtor/libqpsd

These dependencies are not needed for compiling PhotoQt. However, if they are installed, you can set PhotoQt (via settings) to make use of them for improved XCF/PSD support.

1. cd build/

2. cmake ..

   # Note: This installs PhotoQt by default into /usr/local/{bin,share}
   # To install PhotoQt into another prefix e.g. /usr/{bin,share}, run:

   cmake -DCMAKE_INSTALL_PREFIX=/usr ..

   # PhotoQt makes use of the libraries Exiv2, GraphicsMagick ("gm") and LibRaw.
   # You can en-/disable them with the following options:
   # (if you don't specify anything, it asumes a value of ON)

   -DEXIV2=OFF
   -DGM=OFF
   -DRAW=OFF

   # You can combine them in any way you want.
   # The following option equates to setting the two above options to OFF

   -DQTONLY=ON

   # If CMake aborts with the error that it can't find Exiv2 and/or GraphicsMagick and/or LibRaw,
   # but you're certain that the header files are available, then
   # you can pass their locations to CMake:

   -DMAGICK_LOCATION=/path/to/graphicsmagick
   -DEXIV2_LOCATION=/path/to/exiv2
   -DLIBRAW_LOCATION=/path/to/libraw

3. make
   # This creates an executeable photoqt binary located in the ./build/ folder

4. (as root or sudo) make install

   # This command:

   1. installs the desktop file to share/applications/
   2. moves some icons to icons/hicolor/
   3. moves the binary to bin/

If you want to uninstall PhotoQt, simply run make uninstall as root. This removes the desktop file (via xdg-desktop-menu uninstall), the icons and the binary file. Alternatively you can simply remove all the files manually, that should yield the same result.
