#78 Post stacking failure
I can't get lynkeos to give me a full image after aligning "full image" then"analyzing" then finally "stacking the images.
I start with 80% of the moon (in this case) and when the final stage completes it only gives the "9:00 to 12:00 quadrant of the original image.

I went with the standard alignment square on a small crater, then stacked the entire image, and it would only produce a quarter of the image.
There would never show any error, as far as lynkeos was concerned it did the process just fine, even though 75% of the image was not processed.

Please also attach a log recorded when this bug appears (cf. Troubleshooting).
I am having the same problem with Mac 10.10, the original images are like 600x800 but still will only show 25% of the final stack
Wondering if this is a retina problem - also have the same issue

I have the same problem with my MacBook Pro Retina late 2013, and I think this is cause by the retina display because when I try on an external monitor it just works fine.
So for instance the solution is tu use an external monitor, or we need a trick to use Lynkeos as a non-retina software.
I fine a solution for retina displays, 1 clic on the icone of Lynkeos, then cmd + i and you tick "open in low resolution".
It become uggly but it works.
This solution solved the problem. Thanks !!
Bonjour, I have the same problem with my MacBook Pro Retina High sierra v10.13.6. After accumulation, I see only the upper left quarter of the image, whatever the size of the allignment and analysis square and whatever the shape of the accumulation rectangle. It is also independent of all parameters used earlier in the alignment and calibration process, and whether or not I use dark and flat frames.
Can you help please?
best regards,
jm
I had the same issue. The opening in low resolution did not work.
But I could get it to work by downloading a free app "Easy Res" (on the Mac App Store) that allows you to select non-retina resolutions.
Here is the app: https://itunes.apple.com/us/app/easyres/id688211836?mt=12
Then click on the icon of the app (on your Mac top bar), select your screen, and then select a non-retina resolution 1650x1050 for example)
Lynkeos version 3.0, which was released yesterday, was complied on a macOS 10.13 Retina MacBook Pro.
Pleae check with this latest version.
On my MBPr on macOS 10.13.6 the problem is still there, I need to use the application in non-retina resolution.
This is an issue with the access to image data using Cocoas API.
The image format which is the object of this ticket is JPEG, which is a lossy compression format. That kind of format is not suited to image processing, as the "blocky" compression algorithm of the JPEG format introduces horizontal and vertical artifacts during the processing.
Note: this is not an excuse to skip this bug correction ;o) I have a fix which will be delivered soon.
