It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
[Solved] Error Saving Images in 2.0.0-beta6 (Mac OS M1)
I cannot successfully save a usable image from the Tools menu in Version 2.0.0-beta6, using MacOS arm64 M1.
When saving as a TIFF or JPG, the image saves, but is almost pure black and there are few details in the image. Attached is a screen shot from the preview window and the TIFF.
When saving as a PNG, I receive the below.
Encountered error in module: PNGImageSaver
Error message: java.lang.NullPointerException: Cannot invoke "String.length()" because "" is null
Cause: Cannot invoke "String.length()" because "" is null java.desktop/javax.imageio.stream.ImageOutputStreamImpl.writeBytes(Unknown Source) java.desktop/com.sun.imageio.plugins.png.PNGImageWriter.write_tEXt(Unknown Source) java.desktop/com.sun.imageio.plugins.png.PNGImageWriter.write(Unknown Source) qv.a(Unknown Source)
edit by Mabula: solved and fixed in 2.0.0-beta7

@david I just tested saving to JPG and to PNG in beta6 on my Intel MacBook with macOS Ventura and APP 2.0.0-beta6 and both work as advocated. The images end up stretched and saving works fine without any error. What version of macOS are you on? Did you install the M1 version of APP 2.0.0-beta6?
I am on Monterey 12.6, and am using the M1 version.
In experimenting, I switched the openGL4 mode to CPU, and the image saved as expected! Oddly, when I switched from CPU to openGL4, the image also saves and now continuously saves. Perhaps the issue was somehow related to my previous version?
In any event, the image now saves as expected, although the PNG issue persists.
I have added this to our ToDo list to investigate saving to PNG with our latest version especially on macOS 😉
Do I understand correctly now, that saving to TIFF is working, but PNG always gives that error in your case?
The switch between OpenGL and the CPU image viewer will indicate a probleem with showing the data using OpenGL, so I would suggest to make sure that you have the latest graphical drivers from the manufacturer of your graphic chip installed to be sure that that is not the issue.
Yes, saving is working, but previously it was not.
I was using 1.0.83 which worked perfectly. I installed Beta 2.0.0-6 and found I could no longer save images. I went back to 1.0.83 and images saved. While IN 1.0.083 I toggled between openGL4 and CPU. Images saved. I went back to 2.0.0-beta6 and now the images save. Perhaps an old setting was somehow incorrect which is now resolved?
Just to follow-up, has everything been working find with PNG saving now? I tested it and all seems to work without any issue with PNG saving on macOS M1 and the other platforms.
Well, it WAS working, and now today it is not, with the attached error. Previously, after receiving this error, it went away and the files saved in PNG.
Now, today the error is back and only an empty PNG is created. Saving as a TIFF continues to work perfectly.
Okay, then I think the error is somewhere in your specific workflow.. at what tool or moment does this occur? So I need to know exactly at what moment in processing you try to save to PNG.
The shortest possible path to make this happen is:
Open APP.
Go to Tools.
Add a red, green and blue channel and formula RGB 1. Click (re) calculate. Click the Save button on the right side of the screen. Fill out the dialog box as shown. Click OK.
