pcond: error reading from pfilt process in fovimage

Hi Radiance community,

Anybody else has issue running pcond in recent versions of Radiance? Here
is the error.

*pcond: error reading from pfilt process in fovimage*

I still have the older version of Radiance (4.2..a) also installed which
has no problem with the same image.

Here is one of the images which fails. Cloudy sky for Denver:

Try pcond -h to reproduce the error.

Thanks,
Mostapha

I couldn't reproduce the error under MacOS X. Did you try shortening the file name?

Hi Greg,

Just tested and shortening the file name doesn't help. It gives the same
error. Sorry that I forget to mention that I am running Radiance on Windows.

Thanks,
Mostapha

Well, pfilt hasn't changed in 4 years and pcond hasn't changed in 8, so my only remaining guess is that the new way we're calling popen() under Windows is somehow at fault. This call that was hand-written by Georg Mischler was recently replaced under Microsoft's Visual-C compiler, and I think the issue is that I'm not explicitly setting the binary file type in pcond. Schorsch's win_popen() must have done this for me without my realizing it.

I have checked in the new module and it should get recompiled at some point. My apologies, and I hope this solves the issue.

In the short term, just use the older version of pcond. It's the same, anyway.

Cheers,
-Greg

Hi,
it must be a Windows problem.
no problems using mac or linux (head-release 3 weeks ago).

Umm... maybe not. This is specific to pcond -- I didn't find a similar oversight in any of the other programs. Can you tell me what command(s) are giving your errors, exactly?

Thanks!

fyi in case anyone was trying to pipe falsecolor / gencumulativesky-generated
pics
through pfilt lately, the same error seemed to occur in this scenario - glad
it'll be cleared up :slight_smile:

Yeah so that's not terribly useful info without this link:

https://www.dropbox.com/s/n9m921k4gvgggzj/pcond.exe?dl=0

In my defense, Outlook seems to default to sending the email when you
press "return" 2x quickly — which is, like, idiotic.

Anyhoo, Windows users, please grab the copy of pcond.exe found at the
above link and test it out, and report success/failure on this here
frequency.

Ha...You are right!

Thank you for being awesome Greg and Rob! :wink:

PS: Max, I tested the new pcond for a number of falsecolor images and
everything looks to be working fine.

You aren't feeding the output of falsecolor into pcond, are you? Because that doesn't make sense.

Hmm. Actually I do give the user the option to do it for any HDR image
including falsecolor images! In this case I was just testing to see if it
fails but in general I need to modify the workflow and make sure to give a
warning for falsecolor images. Thanks for the note. I really appreciate it.
Will get it fixed soon. - Mostapha
