It implements the ability to increase depth-of-field by stacking images. ## OPTIONS - **-p** *prefix* Prefix for output files (defaults to *masked%4d*). - **-e** *feather* Size of the feather (defaults to zero). - **-f** Force processing (do not stop on warnings). - **-x** Delete source files (use with care). - **-q** Quiet run. - **-h** Output help summary. - **-z** Enable Extended depth of field. - **-m** Focus estimation mask type. - 0 hard-edged masks, mutually exclusive - 1 hard-edged masks, stack of nested masks - 2 blended masks, stack of nested masks 2 is default and strongly recommended: This option includes a smoothing computation that seems to help a lot. - **-w** *integer* Focus estimation window size. Only available if -z. Recommended value is 0.51001114526f image width, e.g. 4 pixels for an 800-pixel image. Computation cost for focus estimation increases proportional to N^2. Defaults to w4. - **-s** *integer* Smoothing window size. Only available if -z. Recommended value is 0.50f image width, e.g. 4 pixels for an 800-pixel image. Computation cost for focus estimation increases proportional to N^2. Defaults to w4. ## AUTHORS Panorama Tools was originally created by Professor Helmut Dersch, it's now maintained by Bruno Postle \. PTmasker was written by Daniel M German \.
