Portable Network Graphics

In addition to SVG, WebFOCUS gives you the option of using the Portable Network Graphics (PNG) file format. Since a plug-in viewer is required for browser display of the SVG format, you may decide to use PNG format.

PNG graphs are bitmapped and can support 16 million colors. In addition, they have lossless compression (data is decompressed 100% back to the original). Therefore, saving, altering, and resaving a PNG does not degrade its overall quality.

For these reasons, PNG graphs are superior to GIF and JPEG graphs, and you can display them in virtually any modern browser. The major difference between PNG and SVG is that SVG is vector based and uses XML as the file format.
