Extract data from texture

Hello,
how may I extract data from a dx9 texture. I have found the pipet patch, but it seem that it may only extract single values from the texture. I do like to extract an area of interest like a 64x64 pixel area from the hugher texture.

Regards Sumopi

nono.

the pipets help patch (F1 on the selected pipetnode) shows exactly how you can get an area of points with the help of the cross node. the pipets inputs for X and Y are spreadable!
