L_LTFIL_API L_INT L_ReadFileGeoKeys(pszFile, uFlags, puTagCount, ppTags, puDataSize, ppData, pLoadOptions)
Gets all the TIFF Geo keys stored in a file.
Character string that contains the input file name.
Flag that determines whether to read the tag overall data. You can combine values when appropriate by using a bitwise OR ( | ):
|READFILEMETADATA_NOMEMORY||[0x01] Do not read the tag overall data. If this flag is set, then puDataSize and ppData will not be used and the function will not read the geo key overall data.|
Address of the variable to be updated with the number of geo keys found in the file.
Pointer to an array of pLEADEADFILETAG structures. Each element of the array contains data for one geo key field found in the file. The number of elements in ppGeoKeys is puGeoKeyCount. When this array is no longer needed pass it to the L_FreeFileTags function to free the allocated memory.
Address of the variable to be updated with the size in bytes of the overall geo key fields data.
Address of the variable to be updated with a pointer to the overall geo key fields data. The size of this pointer in bytes is
puDataSize. Each LEADEADFILETAG item found contains an offset to where the data for this item is stored in ppData.
Pointer to optional extended load options. Pass NULL to use the default load options.
|SUCCESS||The function was successful|
|< 1||An error occurred. Refer to Return Codes.|
You must free the data allocated with this function using the L_FreeFileTags function.
