So, it is desirable to update your copy of Lensfun's database to stay up-to-date. In particular, if you have sent calibration pictures to Torsten's calibration service, you must update your local Lensfun database after the calibration in order to be able to use the new calibrations.</p> <p>For this purpose, there exists a simple command-line tool called “update‑lensfun‑data”. If you call it (it doesn't need parameters), just wait for a second and the database is updated. It will report whether an update was necessary.</p> <p>If you want the updates to be installed system-wide, the program needs root privileges. So call the program with “sudo lensfun‑update‑data” and enter your root password. There exists a second version of the programm called “g‑lensfun‑update‑data”. It will let you enter the root password – if new data is available – in a neat window. This version is especially useful for GUI programs, which can call it in the background.</p> <p>If it is sufficient that the updates are available to only your user account, call “lensfun‑update‑data” without root priviledges. The updates are then written to ~/.local/share/lensfun/updates”.</p> <p>In case there is more than one version of Lensfun on your system (e.g. you installed a new version, but the original version of your Linux distribution is still there and used by some programs), “lensfun‑update‑data” tries to detect this and updates the other database versions, too. </p> </div></div><!-- PageDoc --> </div><!-- contents --> <!-- start footer part --> <hr class="footer"/><address class="footer"><small> Generated on Thu Oct 3 2019 15:07:50 for lensfun by  <a href="http://www.doxygen.org/index.html"> <img class="footer" src="doxygen.png" alt="doxygen"/> </a> 1.8.15 </small></address> </body> </html>
