XnView Software

Hello,

I have 6500 pictures in ECW format (orthophoto) and I need to merge them on mosaic of 25 images (5X5). With XnView, it's possible to make a panorama in height and width. But, my system is busy when I try to merge only 2 file (process xnview.exe = 380 Mo in memory), I work under Windows 2000, Pentium 4, 512Mo RAM. Under Linux, ECW is not supported.
So, is it possible to make a script which do the work I want? I try to start xnview in a .bat file, it doesn't work. Other scripting methods can help me (in some xnview's screens, I can see "save the script" or Nconvert).

Thank you for your help

If your pictures are all the same orientation and ratio, just mark all images and select create contact sheet. Now just calculate or try the desired values.
I hope this helps.
