Low resolution blurred GUI on macOS High Sierra with retina screen, solution provided

[128bit]

I have attached a screenshot with the two versions of Hugin, with and without the fix.
The differences are not well pronounced on the image, so please zoom in if you cannot see the differences clearly.
If you open the GUI for the fist time even without starting a project you immediately see the low resolution of the GUI on a retina screen.

I have worked out a solution for the problem, add NSHighResolutionCapable to the „Info.plist“ file.
To do so, view the Hugin.app package and open „Hugin.app/Contents/Info.plist“ in your favorite text editor.
At the end of the file you will see something like this:
 <key>CFBundleDocumentTypes</key>
 <array>
  …
 </array>

</dict>
</plist>

Then add this almost at the end of the file BEFORE </dict> and </plist>:
 <key>NSHighResolutionCapable</key>
 <string>True</string>

So that the end looks like this:
 <key>CFBundleDocumentTypes</key>
 <array>
  …
 </array>
 <key>NSHighResolutionCapable</key>
 <string>True</string>

</dict>
</plist>

With this fix the app is high resolution capable and looks like any other app on macOS.
So far I tested this works without problems, if I notice some problems with this fix I’ll notify you.
I would be glad if you would apply the fix for the macOS version.
But nether the less thank you for the great panorama stitching tool 👍.

Thank you for reporting this!

I don't own a retina Mac, so I can't test it myself.
I guess the other apps (PTBatcherGUI.app, HuginStichProject.app and calibrate_lens_gui.app) are also pixelated, could you please change the Info.plist for these as well and check if there are issues?

[128bit (128bit)]

Sorry for the late reply, unfortunately I had forgotten to write about the other apps that you have suggested. I had changed the ohter Info.plist files as well, but I had forgotten to write about that.

But nether the less, all other (PTBatcherGUI, HuginStichProject and calibrate_lens_gui) apps have the same problem, this can also be fixed like Hugin itself, by adding the tag to the Info.plist file.

Does

<key>NSHighResolutionCapable</key>
<true/>

work as well? That is how Xcode wants to format it.

[128bit (128bit)]

Yes, this works as well. I had tried this before but it didn’t worked, I must done something wrong. But now it woks.
