| static FORMAT | get_format_for_dataset (GDALDataset *data) |
Wrapper for GDALDataset and its relevant functions. Provides easy access without GDAL dependencies to library users.
| void * GeoRaster::get_as_array | ( | ) |
Return the data of the GeoRaster as an array. The array contains type of the raster format (get_format). BYTE -> (B)(B)(B) with B of type uint8_t RGB -> (RGB)(RGB)(RGB) with R, G, B of type uint8_t RGBA -> (RGBA)(RGBA)(RGBA) with R, G, B, A of type uint8_t RF -> (F)(F)(F) with F of type float @RequiresManualDelete
| void * GeoRaster::get_band_as_array | ( | int | band_index | ) |
Return the data within a single band of the GeoRaster as an array. The type of the array can be any of: BYTE, RF, or UNKNOWN.
| band_index | the index of the band to be returned as array. |
| GeoRaster::FORMAT GeoRaster::get_band_format | ( | int | band_index | ) |
get the FORMAT of the band at band_index within the dataset. This function is most useful when working with either MIXED datasets or simply for extracting specific band information
| band_index | index of the band whose format will be found |
| uint64_t * GeoRaster::get_histogram | ( | ) |
Return a histogram in the format of ID -> number of occurrences. Only works with BYTE images! @RequiresManualDelete
| int * GeoRaster::get_most_common | ( | int | number_of_elements | ) |
Return the number_of_elements most common IDs in the GeoRaster. Note: This function is optimized for few elements (less than ~10). For use cases where a more complete sorted list is required, the array should be sorted with a proper sorting algorithm. @RequiresManualDelete
| int GeoRaster::get_size_in_bytes | ( | ) |
Return the total size of the data in bytes. Useful in conjunction with get_as_array. An optional pixel_size can be given if it deviates from the standard size saved in the object.
