ARN to HPG Conversion: FAQ

What are ARN files?

ARN is a rare image file format associated with the Astronomical Research Network, an American association formed in 1989. ARN files contain astronomical information and images, and can be created using software programs developed by the Network for PCs and Macs. The format is, however, incompatible with most regular image viewers, so we recommend converting it to a more accessible format.

What are HPG files?

HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics.
