PhotoQt 1.2.1 - Copyright (C) 2015, Lukas Spies (Lukas@photoqt.org),
License: GPLv2 (or later) -- http://photoqt.org
-------------------------------------------------------------------------------
PhotoQt is a fast and highly configurable image viewer with a simple and nice
interface.
DEPENDENCIES
--------------
- Qt >= 5.1 (5.2 or higher recommended)
- CMake (needed for building PhotoQt)
> Make sure that you have the needed Qt modules installed: image formats,
multimedia, svg
> Dependencies, that are needed by default, but can be disabled via CMake
(see INSTALL section):
- Exiv2
- GraphicsMagick
> NOTE
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.
> NOTE
Even though GraphicsMagick initially started as a fork of ImageMagick (in 2002),
trying to build PhotoQt with ImageMagick wont work!
OPTIONAL DEPENDENCIES
-----------------------
- 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.
INSTALL
---------
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 and GraphicsMagick ("gm").
# You can en-/disable them with the following options:
# (if you don't specify anything, it asumes the default values)
-DEXIV2=OFF # default: ON
-DGM=OFF # default: ON
# You can combine them in any way you want.
# The following option equates to setting the two above options to OFF
-DQTONLY=ON # default: OFF
# Note: -DQTONLY overwrites the two individual options above!
# If CMake aborts with the error that it can't find Exiv2 and/or GraphicsMagick,
# but you're certain that the header files are available, then you can specify
# their location via the following environment variables:
MAGICK_LOCATION
EXIV2_LOCATION
# NOTE: IF YOU HAVE PROBLEMS WITH PHOTOQT CRASHING WHEN EXITING (OR NOT EXITING
# AT ALL), THEN THIS MIGHT BE CAUSED BY THE SYSTRAY (OBSERVED IN PLASMA 5.2)
# To solve this, you can compile PhotoQt without a systray by adding the following
# flag to CMake:
-DWITH_SYSTRAY=OFF
3) make # This creates an executeable photoqt binary located in the ./build/ folder
4) (as root or sudo) make install
# This (i) installs the desktop file to share/applications/
(ii) moves some icons to icons/hicolor/
(iii) moves the binary to bin/
UNINSTALL
-----------
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.
