The data is not extracted into the higher level metadata tags, it is only copied to the target image when the image is written. This component is used, e.g., for <em>Exif.Image.StripOffsets</em> for which the sizes are provided in <em>Exif.Image.StripByteCounts</em>. <hr><h2>Member Function Documentation</h2>
