Support for SVG in the Reliance SCADA/HMI system

July 2, 2013

From version 4.6.0

Beginning with version 4.6.0, vector graphics in the SVG format is supported in the Reliance system. This article provides detailed information about the SVG format, benefits of its use, and its implementation in the Reliance SCADA/HMI system.

About SVG

SVG (Scalable Vector Graphics) is a well-designed vector format for 2D graphics that has support for interactivity and animation. The SVG specification is based on an open standard developed by the World Wide Web Consortium (W3C).

SVG and its behavior are defined in the XML format. Thanks to this, SVG images can be created with any simple text editor or with advanced vector graphics editors, such as Adobe Illustrator, Corel DRAW, or the popular and free Inkscape.

SVG's great benefits are its low data requirements, easy indexing, and many others. This format is becoming an industrial standard for vector graphics transfer among different platforms and applications.

Bitmap vs. vector image

As shown in the picture of an enlarged Reliance logo, an unquestionable advantage of vector graphics over raster graphics is the possibility to zoom in and out with no loss of quality.

Support for SVG in Reliance

All modules* of the Reliance SCADA system have native support for displaying SVG images that are in accordance with the SVG Tiny specification (a version of SVG for mobile devices). The vector format and anti-aliasing guarantee the perfect look. If you use clients for smartphones and tablets in your visualization projects (Reliance 4 Smart Client), this format is the best choice.

*With the exception of Reliance 4 Mobile Client
