RC1 1.8 LHE doesn't seem to work

[Ignacio]

Tried it on a 64-bit image, and on previews seems to apply only to changing bands. On the full image, nothing that I note happens.

Hi Ignacio

I can confirm this bug. I can reproduce it easily on Linux, and looking at the cause of the problem, it's clear that it must happen on all platforms. There are two workarounds:

1. Disable parallel processing for modules before applying the LocalHistogramEqualization tool. You can do this very easily from the Process Console with this command:

      parallel -m-

After LHE you can re-enable parallel processing with:

      parallel -m+

2. Use PI 1.7 until we release the final 1.8.0 version on January, which of course will fix all of these threading-related problems.

Harry, try LHE on a real-time preview and you should see the bug in action. Please let me know if otherwise.

Definitely, I should have detected this problem, and other similar ones, before releasing version 1.8. I am very sorry for the inconvenience.

hi juan, as i'm sure you've seen the bug affects lots of modules - Deconvolution and StarMask as well.

Hi

Sorry to say works perfectley

Not to worry, Juan. An early release candidate always accelerates the whole debugging process, which is good.

Happy Holidays,

One more thing, the "parallel -p-" doesn't seem to work, but the "parallel -d" does, correcting the LHE problem.

Hi Ignacio,

I appreciate your understanding and support, but this is an unforgivable error on my part. I should have tested these tools after some last-hour "improvements" I did before the 1.8.0 RC1 release. I was too impatient to release, and that's a beginner's error that I cannot afford.

Happy holidays to you too!

Oh, it's -m- and -m+, sorry. I have fixed the typo in my answer above. With 'parallel -d' you are disabling parallel processing for the whole platform.

Harry,

Sorry to say works perfectley

Please check that you have parallel processing enabled. Enter:

      parallel -q

on the Process Console window, and check if it says 'true' to everything. If it does, then I don't understand how LHE is working for you on PI 1.8

Hi

I have managed to get it to fail by adjusting the sliders a lot , but does work most times

Just to confirm it works perfectley on the image

Hi,

This bug is now fixed. LHE works perfectly with 1.8 RC1. I'll release an update for all platforms next Friday (along with updates for other tools that are not working with RC1).

Thank you for your patience.

This bug is now fixed by update 20121229-3-module, which we have released today. LHE now works without problems with all the processors available. Also take a look at the new real-time previewing functionality of this tool.
