drb-impl-image 1.0.2

DRB Image implementation

ImageNode Implementation

This drb-impl-image module implements images data formats to be accessed with DRB data model. It is able to navigates among the images contents and accessing the image data.

Supported images formats

The current implementation is based on RasterIO module. It has been tested with Tiff/GeoTIFF, Jp2k and png formats.

There are no limitations to use other formats supported by rasterio, see https://gdal.org/drivers/raster/index.html for details.

Image Factory and Image Node

The module implements the basic factory model defined in DRB in its node resolver. Based on the python entry point mechanism, this module can be dynamically imported into applications.

The entry point group reference is drb.impl.
The implementation name is image.
The factory class is encoded into drb_impl_image.image_node_factory.

The image factory creates an ImageNode from an existing image data. It uses a base node to access the content data with the streamed base node implementation.

The base node can be a FileNode (See drb-impl-file), HttpNode, ZipNode or any other node able to provide streamed (BufferedIOBase, RawIOBase, IO) xml content.

limitations

The current version does not manage child modification and insertion. ImageNode is currently read only.
