pstatus

Synopsis

Description

pstatus displays the value returned by the last execution of Pandore operator.

Each Pandore operator returns a value after its execution. This value is operator dependent and can be of the following types:

• an integer;
• a real;
• a character;
• a string
• SUCCESS / FAILURE.

Such a value can then be used to test the completeness of an operator execution or be used as parameter value for another operator.

• For example, on UNIX/LINUX/MACOS system:

     plabeling 8 a.pan b.pan
     a=`pstatus`
     echo "Number of regions=%a%"
  

• For example, on MsDos it is necessary to use the 'pset' command to set a variable with the status value:

     plabeling 8 a.pan b.pan
     call pstatus
     call pset a
     echo "Number of regions=%a%"
  

Result

Examples

• Unix/Linux/MACOS: Display the number of regions which resulted in a segmentation process based on interclass variance maximization:

     pvariancebinarization examples/tangram.pan a.pan
     plabeling 8 a.pan b.pan
     a=`pstatus`
     echo "Number of regions=$a"
  

• MsDos: Display the number of regions which resulted in a segmentation process based on interclass variance maximization:

     pvariancebinarization examples/tangram.pan a.pan
     plabeling 8 a.pan b.pan
     call pstatus
     call pset a
     echo "Number of regions=%a%"
