This property refers to the horizontal focal plane resolution. This is the denominator.
Property Value
The FocalPlaneXResolution is the number of pixels in the image horizontal direction per FocalPlaneResolutionUnit on the camera focal plane.
The FocalPlaneXResolution0 is the numerator for the FocalPlaneXResolution.
The FocalPlaneXResolution1 is the denominator for the FocalPlaneXResolution.
The FocalPlaneResolutionUnit = FocalPlaneXResolution0 / FocalPlaneXResolution1
Explanation
The FocalPlaneXResolution1 property refers to the horizontal 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.
