[Radiance-general] Questions about image size

[Bissell, Andrew]

Hi,

You have a rectangle image description when specifying your -x and -y
values but your -vh and -vv values describe a square image.  I think you
just need to delete your -y variable and you should then get a square
image.  If you want a rectangle image then find the ratio between your
-x and -y value and apply the same ratio between your -vh and -vv
values.

I hope that makes sense.

Andrew

Subject: [Radiance-general] Questions about image size

Hello everyone,


I'm trying to generate a rendering from the following command:
rpict -x 786 -y 576 -ab 4 -ad 1024 -vtv -vp 14.636 -5.376 4.226 -vd
-14.504 13.433 -4.304 -vu 0 0 1 -vh 35.0 -vv 35.0 -vo 0 -va 0 -vs 0
-vl 0 -bv-

However, the pic file generated is in size 576x576. Could anyone tell
why Radiance did this? Thanks.


Yu Sheng
