TIOParams.EXIF_MaxApertureValue
Declaration
property EXIF_MaxApertureValue: Double;
Description
Returns the maximum aperture value of the lens.
Convert to an F-number by calculating the power of root 2 (see the process described for
EXIF_ApertureValue).
Note: Use
EXIF_MaxApertureValue2 for easier access to the value.
sMaxApertureValue := ApexToStr( Sqrt( 2 ), ImageEnView1.IO.Params.EXIF_MaxApertureValue, 'f/' );
if sMaxApertureValue = 'f/0' then
sMaxApertureValue := '';
// Write value
ImageEnView1.IO.Params.EXIF_MaxApertureValue := StrToApex( Sqrt( 2 ), sMaxApertureValue, 'f/' );
