CImage:KwdGetSectEx
The KwdGetSectEx method returns the 4 values from a section type keyword plus a boolean success flag. An example of a section keyword is BIASSEC, which has a value with the format '[c1:c2,r1:r2]', as in '[1030:1044,1:1024]'.
c1, c2, r1, r2, bOK = CImage:KwdGetSectEx( sKwd ) |
sKwd is the keyword name.
c1, c2 are the first and second column values of the keyword.
r1, r2 are the first and second row values of the keyword.
bOK is the success flag: true on success or false on failure.
This method parses the section keyword into its 4 components. If the keyword is not in the image header, then the default values 0, 0, 0, 0 are returned with bOK = false. Testing the returned flag for true/false tells whether the keyword is in the header. Alternatively, KwdGetSect returns only the 4 components from the section keyword value.
Suppose a CImage named I exists and contains keyword "BIASSEC". The following script returns the region components stored in the BIASSEC keyword:

-- read the keyword value |
