fileName
A String containing the input file name.
pageNumber
1-based index of the page from which to read the GeoKey.
id
GeoKey ID. Values of the GeoKey ID range between 0 and 65535. Possible ranges are:
| Range | Meaning |
|---|---|
| 0..1023 | Do not use; reserved for future use. |
| 1024..2047 | GeoTIFF Configuration Keys. |
| 2048..3071 | Geographic/Geocentric CS Parameter Keys. |
| 3072..4095 | Projected CS Parameter Keys. |
| 4096..5119 | Vertical CS Parameter Keys. |
| 5120..32767 | Reserved. |
| 32768..65535 | Private use - use to store your own data. |
The GeoKey data.
You can use this method to obtain the GeoKey data from a particular file.
If no such GeoKey exists in the image, this method will return a null reference.
The most efficient way of reading the GeoKeys in a file is to enumerate them with EnumGeoKeys and then read each GeoKey with ReadGeoKey.
Refer to EnumGeoKeys.
