Squared images
on Dec 20, 2013 at 9:08:59 am

Hi

We have recently bought the software Particle Illusion (we are a Christian Art Foundation).
Everything working just fine, version 3.0.9 has HD options, just great for any movie.
All images are replaceable to a higher resolution one, amazing!
The only thing is bothering me: when i save (render) an image (or sequence), get a squared image instead of a rectangle.
In one word, the width of the image is pusshed to the size of the height.
I really don't know, how to explain this, even not in my own language (Hungarian).
Just look at the attached image.



The squared images came from PI render.
The last one is saved by photoshop's image processor (not altered anything).
My question is: WHY?
My God, have tried several versions of PI (309, 301), giving all the same results, which is very boring, when you have to work with many 10K images.
Is there any option to render the images, in the format, like the last image in the row?

Machines:
Win7 64bit, 4GB ram, Geforce 470 (PC)
Win7 64bit, 8GB ram, Geforce 720 (Lap)

It looks like the pixel aspect ratio might be set incorrectly by pI when saving that. If that's the case, then how you view the image makes all the difference. Are you viewing the image only in Photoshop, or using something else too?

You can fix by having PS ignore the pixel aspect ratio (the pI images are always square pixels). You could also try saving in a format that doesn't save pixel aspect ratio information, like TGA or JPG (I think they both don't save PAR).

I have saved an image in jpg, with the same result.
Further i can't see any pixel aspect ratio option to adjust.
But i have made a new picture, maybe it will help.
Both my computers having the same issue with this.
Would be nice to find the answer.

The "horizontal resolution" is 35dpi and "vertical" is 20dpi -- that's the problem. You need whatever application you want to use these with to ignore those settings -- there's no way to change it in pI. (I don't know why pIRender is doing that). Did you try saving as TGA?

Yes, i tried TGA, the same result (TGA is useless, anyway).
The best way to get the right pixel aspect ratio, to load the whole folder (saved image sequence as PNG or TIF) into the Photoshop's image processor, and save as TIF.
So you can preserve the transparency of the files (but you need HD space, a lot).

But I'm really suprised.
You mean, that every one here having the same issue, and nobody complains about it?
Strange, really. But.... the software is great, no doubt about it.

Can you send me one of the TIF images you rendered and one of the JPG ones too? Send it to alan at genarts dot com.
