CImage:KwdGetSect

The KwdGetSect method returns the 4 values from a section type keyword. An example of such a keyword is BIASSEC, which has a value with the format '[c1:c2,r1:r2]', as in '[1030:1044,1:1024]'.

Syntax

• 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.

Remarks

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. No test is performed to determine if the keyword actually exists. To test whether the keyword exists, call KwdExists before this method. Alternatively, KwdGetSectEx returns 5 parameters: the 4 numeric components and a boolean status value.

Example

Suppose a CImage named I exists and contains keyword "BIASSEC". The following script returns the region components stored in the BIASSEC keyword:
