# PAux -- PCI .aux Labelled Raw Format

Driver short name

PAux

Driver built-in by default

This driver is built-in by default

GDAL includes a partial implementation of the PCI .aux labelled raw raster file for read, write and creation. To open a PCI labelled file, select the raw data file itself. The .aux file (which must have a common base name) will be checked for automatically.

The format type for creating new files is `PAux`. All PCI data types (8U, 16U, 16S, and 32R) are supported. Currently georeferencing, projections, and other metadata is ignored.

Creation Options:

- INTERLEAVE=[PIXEL/LINE/BAND]: Defaults to `BAND`. Establish output interleaving. Starting with GDAL 3.5, when copying from a source dataset with multiple bands which advertises a INTERLEAVE metadata item, if the INTERLEAVE creation option is not specified, the source dataset INTERLEAVE will be automatically taken into account.

NOTE: Implemented as pauxdataset.cpp.
