FAQ

>
Can I use PureRef on OSX or Linux?
Yes!

OSX: PureRef works on OS X 10.12 and newer versions. We made the choice to not support older versions mainly because it is free to upgrade to 10.12 and because we have limited testing access to older versions.

Linux: PureRef is verified to work on Ubuntu 14.04+ and CentOS 7, but should work on most distributions. Unity and KDE are the DE's verified to have support for all features. Some DE's do not support transparency and some will insist on adding a frame to the window. If you are having these issues with your specific DE you are free to contact us and we will see what we can do but we can't promise we will add support for every distribution and DE.

How do I move the PureRef window?
Make sure Maximize is toggled off either through the right click menu -> Window -> Maximize or the shortcut CTRL + F. Hold down the right mouse button to move the window.
>
How do I turn off Mouse Transparency Mode?
The default shortcut is Ctrl+T. Depending on your shortcut settings you might also need to give PureRef focus by clicking on the task bar icon or ALT + TAB to it. If you want to avoid this set the shortcut context to Global. In Windows you can also use the taskbar preview buttons to enable and disable mouse transparency.
>
I would like to use PureRef commercially, do I need a license?
No, PureRef does not have any kind of licensing restrictions and can be used by anyone for both commercial and non-commercial use, read more in the license agreement. We aim to fund future development on single download sales so we hope that those who have the ability to contribute will do so.
>
What image formats does PureRef support?
BMP, DDS, GIF(First frame only), ICNS, ICO, JPEG, JP2, MNG, PBM, PGM, PNG, PNM, PPM, PSD, TIFF, WEBP, XBM, XPM, TGA, SVG, EXR.

PureRef also supports some more formats so even if your format is not listed here PureRef might still support it, give it a try!
>
Can I open multiple instances of PureRef in OSX?
Yes. Open the terminal and type in: open -n -a "PureRef".
>
Can different PureRef windows have different settings?
Yes, in Windows. You can provide PureRef with a path to the settings file on the command line: PureRef.exe -s C:\path\to\settings.ini. To automate this, create a shortcut to PureRef containing the command line settings.
>
What does the 'Context' drop down menu in the keybinder mean?
It indicates in which window context the shortcut will trigger. If it is set to 'Global' the shortcut will trigger even if PureRef does not have window focus. If set to 'Window' it will only trigger for the currently open window that belongs to PureRef. And if it is set to 'Application' it will trigger as long as PureRef has focus.
>
I maximized my window and can't resize it again. Minimize just collapses it to the taskbar. What do I do?
Maximize is a toggle, just press CTRL + F (CMD + F) again or toggle it in the right click menu under Window -> Maximize.
