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.


Example

sShutterSpeed := ApexToStr( 2, ImageEnView1.IO.Params.EXIF_ShutterSpeedValue, '1/' );

// Write value
ImageEnView1.IO.Params.EXIF_ShutterSpeedValue := StrToApex( 2, sShutterSpeed, '1/' );
