CImage:KwdSetSect
The KwdSetSect method formats a region section keyword and inserts it into the image header. An example of a region section keyword is BIASSEC, which has the format '[c1:c2,r1:r2]'.
|
CImage:KwdSetSect( sKwd, c1,c2,r1,r2 ) |
sKwd is the keyword name
c1, c2, r1, and r2 are the
components to be written.
The region section is actually a string-value keyword with a special format. This method formats the 4 components into a region section string and then writes the string to the header. If the keyword name already exists, its value is overwritten by the new value.
Suppose a CImage named I exists. The following script sets the BIASSEC keyword to the region string '[1024:1043,1038:1050]':
|
c1 = 1024 ; c2 = 1043 |
-- column bounds |
|
r1 = 1038 ; r2 = 1050 |
-- row bounds |
|
I:KwdSetSect("BIASSEC",c1,c2,r1,r2) |
-- set the FILTER keyword |
