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.

Example

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/' );
