The aim of the AutoTrace project is the development of a freely-available application similar to CorelTrace or Adobe Streamline. In some aspects it is already better. Originally created as a plugin for the GIMP, AutoTrace is now a standalone program. .

As a library, it presents a single abstract data model to the calling application for all supported formats. The related OGR library (which lives within the GDAL source tree) provides a similar capability for simple features vector data. . GDAL supports 40+ popular data formats, including commonly used ones (GeoTIFF, JPEG, PNG and more) as well as the ones used in GIS and remote sensing software packages (ERDAS Imagine, ESRI Arc/Info, ENVI, PCI Geomatics). Also supported many remote sensing and scientific data distribution formats such as HDF, EOS FAST, NOAA L1B, NetCDF, FITS. . OGR library supports popular vector formats like ESRI Shapefile, TIGER data, S57, MapInfo File, DGN, GML and more. . This package contains utility programs, based on GDAL/OGR library, namely gdal_translate, gdalinfo, gdaladdo, gdalwarp, ogr2ogr, ogrinfo, ogrtindex. .

Currently, its HPGL parser recognizes a subset of the HP 7550A command set. Some high-level functions are missing. Also, only some of the fixed space vector fonts and none of the variable space arc fonts are supported. Beside these limitations, hp2xx has proven to work with many HP-GL sources without any trouble.
