CImage:KwdExists
The KwdExists method tests whether a keyword exists in the image header.
|
bResult = CImage:KwdExists( sKwd ) |
sKwd is the name of the keyword to be tested.
If the keyword
exists, the method returns true.
Otherwise,
false is
returned.
This method returns true if an instance of the named keyword is found in the image header. It does not return information about the contents of the keyword of the location of the keyword.
Suppose a CImage named I exists and contains keyword "DARKTIME". The following script fragment informs the script whether the keyword exists in imageI:
|
if ( I:KwdExists("DARKTIME") ) then |
-- test if keyword is in the header |
|
... |
-- do something |
|
end |
