  • 2: the number of planes (for image, region map and graph);
  • 3: the number of bands for image, or
    the number of labels for region map, or
    the number of nodes for graph (size).

• im_in: a Pandore file.

Result

Returns the value of the selected property.

Examples

• Unix/Linux/MACOS: Build a new image with the same dimension than tangram.pan which contains a white disc of radius 50:

     pproperty 0 tangram.pan; w=`pstatus`
     pproperty 1 tangram.pan; h=`pstatus`
     pshapedesign $w $h 0 1 50 50 a.pan
  

• MsDos: Build a new image with the same dimension than tangram.pan which contains a white disc of radius 50:

     pproperty 0 tangram.pan
     call pstatus
     call pset w 
     pproperty 1 tangram.pan
     call pstatus
     call pset h
     pshapedesign $w $h 0 1 50 50 a.pan
