Difference Between Plain SVG and Inkscape SVG

When working with vector graphics for the web, understanding the differences between plain SVG and Inkscape SVG is crucial. In this article, we'll explore the key distinctions, focusing on the non-standard elements present in Inkscape SVG that may not be part of a plain SVG.

Introduction to SVG

Scalable Vector Graphics (SVG) is a powerful vector graphics format that allows for the creation of scalable graphic images using XML-based language. The specifications for SVG 1.1 Second Edition provide a detailed standard for creating and displaying vector graphics. While plain SVG adheres strictly to these standards, Inkscape SVG may include some additional features and elements not found in its plain counterpart.

Plain SVG vs. Inkscape SVG

Plain SVG is a simple and standardized vector graphics format that strictly follows the guidelines provided by the W3C SVG specification. It is a lightweight and versatile format for creating vector graphics. However, due to its strict adherence to standardization, plain SVG lacks some of the advanced tools and features that are commonly used in modern vector editing software.

Inkscape SVG, on the other hand, is a vector graphics editor that supports SVG 1.1 (Second Edition) and SMIL 2.0 (Second Edition). When saving as SVG, Inkscape may include a few non-standard elements that are useful for web developers but may not conform to the official SVG specifications. These include additional information and metadata that can enhance the functionality and usability of the SVG files.

Non-Standard Elements in Inkscape SVG

The primary difference between plain SVG and Inkscape SVG lies in the non-standard elements added by Inkscape. These elements can provide additional features and improve the performance and interactivity of SVG files. Key non-standard elements include:

Circular Shapes: In plain SVG, shapes such as circles and ellipses are typically defined using paths. In Inkscape, these shapes are often represented as non-standard elements, which can simplify the code and improve readability. Additional Metadata: Inkscape SVG files may include extra metadata fields that provide additional information about the graphic, such as creator information, usage instructions, and other useful data for web designers and developers. Advanced Properties: Inkscape allows users to add advanced properties to elements within the SVG, such as color management data and other proprietary attributes that may not be part of the standard SVG specification.

Benefits and Considerations

The inclusion of non-standard elements in Inkscape SVG can offer several benefits, including improved performance and enhanced interactivity. However, it's essential to consider the compatibility and conformance of these files with different web browsers and tools. Generally, Inkscape SVGs are designed to work well in modern web environments, but there may be instances where a plain SVG format is necessary for strict standard adherence.

Use Cases for Plain SVG

Plain SVG files are ideal in scenarios where strict adherence to web standards is crucial, such as:

Consuming SVGs in legacy systems that strictly require conformance to SVG 1.1 standards. Situations where web browsers with limited SVG capabilities are expected. When interactivity is not a primary concern, and the SVG files need to be as lightweight as possible.

Use Cases for Inkscape SVG

Inkscape SVG files are better suited for:

Projects that require advanced vector manipulation and editing features. Scenarios where enhanced metadata and additional properties are necessary to improve the usability of the SVG files. Cases where interactivity and visual enhancements are important, and the slight loss of standard compliance is acceptable for the benefits gained.

Conclusion

While both plain SVG and Inkscape SVG serve the same purpose of creating high-quality vector graphics, they differ in their adherence to the official SVG specification and the inclusion of non-standard elements. Understanding these differences is vital for web developers, designers, and anyone working with vector graphics for the web.
