Is it possible to display the pixel/mm scale yourself, and not automatically? #51

Open Kaiman777 opened 3 months ago

Hello! Is it possible to display the pixel/mm scale yourself, and not automatically? The program calculates the scale using the diameter of the needle. Is it possible to enter the needle size in pixels or the pixel scale manually? For example, edit param.ini and run the measurement with these settings?

That could be possible as a new feature, are you running this on linux or windows by the way? I can make the edits in the source code but it's been a while since I've built the Windows distribution, and re-figuring out how to do that will take me some time.

Kaiman777 commented 3 months ago

We mostly use Windows. If you have the opportunity to update the build for Windows it will be very good. I can collect more feedback on what settings other people would like.

For example, a colleague asks about the possibility of displaying the diameter of the contact spot of a lying drop (the distance between the points of intersection of the legs with the line of the substrate).It would be great if you add it.

I'll need to try installing opendrop on my windows laptop using Anaconda, and then try to implement the two features you request. I don't have a lot of time to work on this project anymore though so it might take me some time to complete this, apologies.

Thanks a lot. When can we expect an update?

eugenhu commented 1 month ago

Sorry for the lack of updates. I'm currently quite busy with other work at the moment. Although this feature is not necessarily hard to implement, I might need another month before I find time for this. Thanks for your patience.

Ok, sorry for the slow update again. But I've hacked together this manual image scale feature. Here's the patched windows zip: https://github.com/jdber1/opendrop/releases/download/v3.3.2/OpenDrop-3.3.2-Windows.zip

If you manually specify a px/mm, you don't have to select a needle region anymore. Try water_in_air001.png from the example images below with 150.45 px/mm.

Let me know if you have any other questions. I don't think I have the time to implement displaying the diameter of the contact spot. I may get around to it eventually but I can't promise a timeline. This project probably needs a new maintainer to be honest if there is interest for more features to be implemented.

Thank you very much for this version. We'll try to use it and if there are any errors we'll let you know.
