1108 : * \brief Create a copy of a dataset.
1109 : *
1110 : * This method will attempt to create a copy of a raster dataset with the
1111 : * indicated filename, and in this drivers format. Band number, size,
1112 : * type, projection, geotransform and so forth are all to be copied from
1113 : * the provided template dataset.
1114 : *
1115 : * Note that many sequential write once formats (such as JPEG and PNG) don't
1116 : * implement the Create() method but do implement this CreateCopy() method.
1117 : * If the driver doesn't implement CreateCopy(), but does implement Create()
1118 : * then the default CreateCopy() mechanism built on calling Create() will
1119 : * be used.
1120 : * So to test if CreateCopy() is available, you can test if GDAL_DCAP_CREATECOPY
1121 : * or GDAL_DCAP_CREATE is set in the GDAL metadata.
1122 : *
1123 : * It is intended that CreateCopy() will often be used with a source dataset
1124 : * which is a virtual dataset allowing configuration of band types, and other
1125 : * information without actually duplicating raster data (see the VRT driver).
1126 : * This is what is done by the gdal_translate utility for example.
1127 : *
1128 : * That function will try to validate the creation option list passed to the
1129 : * driver with the GDALValidateCreationOptions() method. This check can be
1130 : * disabled by defining the configuration option
1131 : * GDAL_VALIDATE_CREATION_OPTIONS=NO.
1132 : *
1133 : * This function copy all metadata from the default domain ("")
1134 : *
1135 : * Even is bStrict is TRUE, only the <b>value</b> of the data is equivalent,
1136 : * but the data layout (INTERLEAVE as PIXEL/LINE/BAND) of the dst dataset is
1137 : * controlled by the papszOptions creation options, and may differ from the
1138 : * poSrcDS src dataset.
1139 : * Starting from GDAL 3.5, if no INTERLEAVE and COMPRESS creation option has
1140 : * been specified in papszOptions, and if the driver supports equivalent
1141 : * interleaving as the src dataset, the CreateCopy() will internally add the
1142 : * proper creation option to get the same data interleaving.
1143 : *
1144 : * After you have finished working with the returned dataset, it is
1145 : * <b>required</b> to close it with GDALClose(). This does not only close the
1146 : * file handle, but also ensures that all the data and metadata has been written
1147 : * to the dataset (GDALFlushCache() is not sufficient for that purpose).
1148 : *
1149 : * For multidimensional datasets, papszOptions can contain array creation
1150 : * options, if they are prefixed with "ARRAY:". \see GDALGroup::CopyFrom()
1151 : * documentation for further details regarding such options.
1152 : *
1153 : * @param pszFilename the name for the new dataset. UTF-8 encoded.
1154 : * @param poSrcDS the dataset being duplicated.
1155 : * @param bStrict TRUE if the copy must be strictly equivalent, or more
1156 : * normally FALSE indicating that the copy may adapt as needed for the
1157 : * output format.
1158 : * @param papszOptions additional format dependent options controlling
1159 : * creation of the output file.
1160 : * The APPEND_SUBDATASET=YES option can be specified to avoid prior destruction
1161 : * of existing dataset.
1162 : * Starting with GDAL 3.8.0, the following options are recognized by the
1163 : * GTiff, COG, VRT, PNG au JPEG drivers:
1164 : * <ul>
1165 : * <li>COPY_SRC_MDD=AUTO/YES/NO: whether metadata domains of the source dataset
1166 : * should be copied to the destination dataset. In the default AUTO mode, only
1167 : * "safe" domains will be copied, which include the default metadata domain
1168 : * (some drivers may include other domains such as IMD, RPC, GEOLOCATION). When
1169 : * setting YES, all domains will be copied (but a few reserved ones like
1170 : * IMAGE_STRUCTURE or DERIVED_SUBDATASETS). When setting NO, no source metadata
1171 : * will be copied.
1172 : * </li>
1173 : *<li>SRC_MDD=domain_name: which source metadata domain should be copied.
1174 : * This option restricts the list of source metadata domains to be copied
1175 : * (it implies COPY_SRC_MDD=YES if it is not set). This option may be specified
1176 : * as many times as they are source domains. The default metadata domain is the
1177 : * empty string "" ("_DEFAULT_") may also be used when empty string is not practical)
1178 : * </li>
1179 : * </ul>
1180 : * @param pfnProgress a function to be used to report progress of the copy.
1181 : * @param pProgressData application data passed into progress function.
1182 : *
1183 : * @return a pointer to the newly created dataset (may be read-only access).
