+ This causes pamcut to write to Standard Output a description of the + cutting it would have done instead of producing an output image. See + below for a description of this output and ways + to use it. + +

That description is one line of text, containing 6 decimal numbers of + pixels, separated by spaces: + +

    +
  1. column number of left cut +
  2. column number of right cut +
  3. row number of top cut +
  4. row number of bottom cut +
  5. output width +
  6. output height +
+ +

The column number of the left cut is the column number in the input image +of the leftmost column of the output image. for the right cut, it is for +the rightmost column of the output. Top and bottom are analogous. + +

The column and row numbers can be negative. This means you +specified -pad and pamcut would have added padding there. + +

Example: + 

+    
+      4 3 -1 2 100 100
+    
+
+ +

This option was new in Netpbm 11.06 (March 2024). +
