Re: [HDRI] Duplicated lines in HDRI header

Sun, 01 Oct 2017 14:38:01 -0700

Hi Belal,

I am not familiar with hdrscope, but you might inform the author that it's not a good idea to remove the tabs when reporting the header, since they are very important to the interpretation of the image.

Since all of the views are indented in your header, you will at minimum need to add back a valid VIEW= line to the header, using the getinfo "-a" option we discussed earlier, e.g.:

getinfo -a "VIEW= -vta -vh 180 -vv 180" < processed.hdr > final.hdr

Best,

Hi Greg,

The header does contain indentations. The header I posted to forum is copied from hdrscope. Attached is the header file (directly from radiance) and the Image.

Thank you very much for helping,

The header lines from the inputs to pcomb and pcompos should be indented, which leads their being ignored during processing.

If your header is lacking the indentations, then something may be going wrong in your processing chain.  Can you e-mail me your actual image so I may examine the header directly?

Hi all,

I am putting together a post processing cmd batch file to convert image to hemispherical, resize, crop, mask, apply vignetting image, etc. The problem I'm facing is that header of the resultant HDRI header contains some duplicated lines, I am particularly concerned about view and exposure lines, as you can see below:

#?RADIANCE
CAPDATE= 2017:09:30 22:49:12
GMT= 2017:10:01 05:49:12
9_1043com.hdr:
CAPDATE= 2017:09:30 22:49:10
GMT= 2017:10:01 05:49:10
maskc.hdr:
ra_bmp -r
9_1043cs.hdr:
CAPDATE= 2017:09:30 22:49:09
...
EXPOSURE=0.342682082

I am eager to hear your input on how to clean it up so it'd run in Evalglare. Any suggestions are greatly appreciated! 

Best,
Belal Abboushi
