#81 Lynkeos 2.9 freezes when stacking large amounts of data

[Anonymous]

Lynkeos 2.9 freezes when stacking large amounts of large raw pictures. In my case: about 1GB of pic data, approx.60 files, canon EOS 550D .cr2 files. Freeze happens already when adding the pictures...

Same happens in 2.10...just checked.
The pictures get loaded into Lynkeos, but when you click on the first picture, Lynkeos 2.10 freezes...

Update2: the time until -after a click- the first picture is displayed increases heavily with the number of pics. When adding only 30 pics with 25 MB each, Lynkeos 2.10 eventually works!

When a "raw" file, such as a CR2 is loaded, Dcraw is launched in the background to extract RGB data from the file. This processing takes some seconds per file.

When you click in the list panel, Lynkeos needs to wait for Dcraw to finish its work before being able to display the image. When you add 60 files, 60 conversions are started in parallel, and they may take one or two minutes to complete. However, adding several files at once allows to spread the conversions on available cores.
You may be impatient to see your picture in the image panel, but you have to wait for the conversions to complete.

Please confirm that you observe this when adding the pictures, not when stacking.

One more advice, each "raw file" is converted into an uncompressed file in a temporary folder. So when processing large numbers of files, be sure to have a large amount of available disk space.

Release v3.0 adds a progress pane for RAW file opening, which helps distinguish between a stuck app and RAW file opening in progress.

No news since v3.0 release.
Let's consider that the progress pane solves this.
