TIOParams.EXIF_ShutterSpeedValue
TIOParams.EXIF_ShutterSpeedValue
Declaration
property EXIF_ShutterSpeedValue: Double;
Description
The shutter speed as an APEX value.
To convert this value to a human-readable "Shutter Speed" calculate this value's power of 2, then make it a reciprocal. For example, if EXIF_ShutterSpeedValue is 4, then the shutter speed is 1/16 second.
Note: Use
EXIF_ShutterSpeedValue2 for easier access to the value.
sShutterSpeed := ApexToStr( 2, ImageEnView1.IO.Params.EXIF_ShutterSpeedValue, '1/' );
// Write value
ImageEnView1.IO.Params.EXIF_ShutterSpeedValue := StrToApex( 2, sShutterSpeed, '1/' );
