Can't ope .tiff compressed with LZW

[28446]

Hi,
when I try to open such files I get LuckyStackWorker stacked in a "loading" attempt.
I don't know if it s an LuckyStackWorker issue or my java installation.

Debian testing
openjdk 17
openjdk 21

I have both pakages

Thank you

Regards

Hi @28446 ,
LuckyStackWorker uses its own bundled JRE (azul openjdk 21), so there is no need to install java seperately.
You say it is "stuck in a loading attempt".
I'm not sure what you mean by that, when you launch the app from the launchpad, does the control panel show up?

Also, are you running on a apple silicon mac (M1-M4), or an Intel processor mac? And exactly which DMG file did you download?

Regards,
Wilco.

Sorry I didn't read the title of your message. If you got as far as selecting a tiff file for opening it means that the app started correctly and all is fine.
Regarding the LZW compression, this application is meant to be used in exclusively in conjunction with planetary stacking software such as Autostakkert or PlanetarySystemStacker. These produce raw uncompressed 16-bit TIF or PNG files (RGB or grayscale).
Other file formats such as compressed ones are not supported because they are produced using other software.

Wilco.

Hi Wilco,
many thanks for the prompt reply.
I use PlanetarySystemStacker 0.8.32 and it save compressed TIFF (LZW) only, I prefer TIFF over PNG for quality reason.
To open a file form LuckyStackWorker I have to pass form GIMP>export to uncompress the image

Thanks for letting me know, I wasn't aware of the fact that PlanetarySystemStacker uses this format. So far the app has been tested with Autostakkert, which can be run also on MacOS now using Wine. If you want I can provide you with instructions on how to do that, I have it running fine on my own mac M3.
