[GRASS-user] High Resolution ppm

It should happen automatically; presumably you do not have the
NetPBM tools installed?

Once installed 'pnmcat -lr' is used to assemble rows, then
'pnmcat -tb' is used to combine those assembled rows into the
final image. You can try running those manually.

Hi Hamish

Thank you for your hints, however I didn’t managed to solve the problem.
I installed NetPBM tools has you suggested, however I still get hundreds of .ppm files instead of one big high resolution file like I need.

I then tried Windows command prompt with these sentences:

C:\Program Files (x86)\GnuWin32\bin>pnmcat -lr C:\Users\Andre\Pictures\aaa\E-W-45_1_1.ppm

C:\Program Files (x86)\GnuWin32\bin>pnmcat -tb C:\Users\Andre\Pictures\aaa\E-W-45_1_1.ppm

In both cases all I get has output can be seen in attachment, but no assembled image is produced.

What am I doing wrong? Is there an alternative method to assemble .ppm tiles?

Thank for your time

Best wishes
