[Radiance-general] Up-sampling a radiance picture?

[Claus Brøndgaard Madsen]

Hi Lars,

Thanks! That was also my immediate idea ... then I read the man-page and saw that when using -x xres, xres has to be less than or equal to the target device. And when I read that I was reading it too quickly and simply "reading" (or getting the understanding) that xres needs to be less than or equal to the input resolution.

Sorry. One can say I was not reading what was written, but rather what I was fearing to read.

Best,
Claus

Hi Claus,

you can use pfilt to do that. The -x and -y parameters allow to set a target resolution. Many use them like -x /2 -y /2 to downsample, but you can also do the opposite by setting -x /.5 -y /.5 and achieve upsampling.

Cheers, Lars.
