PLT Viewer API - Open HPGL Plot Files Online

PLT files carry plotter instructions in HPGL, the Hewlett-Packard Graphics Language. CAD packages and cutting machines produce them, and outside those programs almost nothing opens them. GroupDocs.Viewer Cloud handles the format directly: its REST API renders the drawing and returns HTML, PDF, JPG or PNG, which any browser or Android app can display.

For Android integration there is a Java SDK with code samples, installed through Maven or Gradle. Render the full drawing or selected pages, generate thumbnails for a drawing list, and let users zoom into the fine lines of the plot.

When only one file needs checking, the free GroupDocs.Viewer online app shows the plot in your browser. That is a practical answer when a contractor sends a .plt drawing and your CAD workstation is somewhere else.

More than 180 formats reach this API, and PLT is one of them. Test calls interactively in the API Explorer, then continue with a free trial.
