This property refers to the vertical focal plane resolution. This is the denominator.
Property Value
The FocalPlaneYResolution is the number of pixels in the image vertical direction per FocalPlaneResolutionUnit on the camera focal plane.
The FocalPlaneYResolution0 is the numerator for the FocalPlaneYResolution.
The FocalPlaneYResolution1 is the denominator for the FocalPlaneYResolution.
The FocalPlaneResolutionUnit = FocalPlaneYResolution0 / FocalPlaneYResolution1
Explanation
The FocalPlaneYResolution1 property refers to the vertical focal plane resolution.
The property value can be retrieved by executing the File.GetImageFileType or the File.GetImageFileTypeFromRawData method.
The property value is derived from the image tags related to the picture taking conditions.
