Rogue Wave JViews Framework Sample: Reading a DXF File
Description
 |
This sample shows how to read DXF files in Rogue Wave JViews.
How to Use the Sample
- The demonstration automatically loads the file
resources/namap.dxf. - When running the demonstration as an application (not as an applet), you can select the DXF file to import by pressing the "Load" button.
How to Run the Sample as an Application
This sample can also be run as an application. The installation directory contains an executable JAR file, jviews-dxf-reader.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.
Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Rogue Wave JViews.
Then, go to the installation directory of the sample and type:
ant run
Topics Covered
- Reading DXF Files.
- Converting DXF Files to IVL Files.
Detailed Description
This sample shows how to read DXF files by using the DXF reader provided in Rogue Wave JViews.
Using the DXF Reader
The DXF Reader can be used in other applications. To read a DXF file, you can write the following code:
IlvManager manager = new IlvManager(0); // with no layer
IlvDXFReader reader = new IlvDXFReader();
try {
reader.read("myDXFFile.dxf", manager);
} catch (IOException ex) {
ex.printStackTrace();
}
The read method of the IlvDXFReader reads the DXF file and adds the graphic objects defined in the DXF file to the manager. If an error occurs during this process, an exception of the type IOException can be thrown that must be caught. About the DXF Format
The DXF format (Drawing Interchange Format) is the interchange format of AutoCAD. This format supports vector graphics (polygons, arcs, lines, points, ...) and layers.
A sample DXF file is provided with this sample.
