SVG Tutorial – Learn SVG Basics

SVG is an XML-based language for creating vector graphics. You can write SVG markup in a text editor, inspect it in a browser, and then process it with Aspose.SVG APIs when you need to generate, edit, render, or convert SVG files from code.

This tutorial explains the SVG concepts that appear in most real workflows: coordinate systems, viewBox, shapes, paths, text, colors, fills, strokes, gradients, filters, transforms, and embedded content. Use it as a foundation before moving to API-focused articles about SVG editing, conversion, vectorization, or document generation.

Coordinates and Layout

SVG Coordinate Systems and Units explains SVG canvas, viewport, user coordinate systems, and coordinate units.
SVG viewBox shows how viewBox scales, crops, and repositions SVG graphics.

Shapes, Paths, and Text

SVG Shapes covers rectangles, circles, ellipses, lines, polylines, and polygons.
SVG Path Data explains path commands for lines, arcs, Bézier curves, and custom outlines.
SVG Text introduces <text>, <tspan>, and <textPath> elements for displaying and styling SVG text.

Color and Painting

SVG Color explains color values, fill, stroke, opacity, and color use for shapes, paths, and text.
Fills and Strokes in SVG focuses on the SVG painting model, stroke width, line caps, joins, and dashes.
SVG Background Color shows reliable ways to add or change an SVG background.
SVG Gradients explains linear and radial gradients, stops, directions, and reuse through url(#id).

Effects and Transformations

SVG Transformations covers translate, scale, rotate, skew, and matrix transform functions.
SVG Transformation Matrix explains the matrix model behind SVG transformations.
SVG Filters introduces blur, drop shadow, lighting, and color filter primitives.

Embedded Content and Practice

SVG Embedded Content shows how SVG can include raster images, nested SVG, and HTML through embedded content.
How to Draw a Snowflake is a practical SVG project that uses reusable elements, rotation, and animation.

How to Use This SVG Tutorial

Start with the topics that match the problem you need to solve:

Learn coordinates and viewBox first if you need to understand SVG layout, scaling, cropping, or responsive graphics.
Use shapes, paths, and text when you need to draw SVG geometry or create readable text in markup.
Use color, fill, stroke, gradients, and backgrounds when the SVG structure is correct but the visual style needs work.
Use filters and transformations when you need blur, shadows, lighting, rotation, scaling, skewing, or matrix-based positioning.
Move to Aspose.SVG API articles when you need to generate, edit, convert, render, or vectorize SVG files from code.

The examples in this tutorial use SVG markup directly. The figure below shows the Aspose logo rendered as an SVG image. Even a small SVG fragment can define a reusable icon, logo, or simple illustration.

Aspose logo rendered as an SVG image

The snippet below is a compact SVG markup example for the Aspose logo. You can also open the source file: aspose.svg.

1<svg height="400" width="400" viewBox="-40 0 400 400" xmlns="http://www.w3.org/2000/svg">
2    <path d="M 25 78  C -26 28  97 -15  98 91 C 86 34 16 33 25 78" fill="#3993c9"/>
3    <path d="M 25 78  C -26 28  97 -15  98 91 C 86 34 16 33 25 78"  fill="#f3622a" transform= "rotate(90 30 64) translate(5 -14)"/>
4    <path d="M 25 78  C -26 28  97 -15  98 91 C 86 34 16 33 25 78"  fill="#c1af2c" transform= "rotate(180 25 78) translate(-19 9)"/>
5    <path d="M 25 78  C -26 28  97 -15  98 91 C 86 34 16 33 25 78"  fill="#499c43" transform= "rotate(-90 25 78) translate(-5 14)"/>
6    <circle cx="34.5" cy="73.5" r="40"   fill="white" fill-opacity="0.3" />

Aspose.SVG offers free SVG web applications for converting SVG or image files, merging SVG files, vectorizing images, generating SVG sprites, encoding SVG as Base64, and vectorizing text. These online apps work in a browser and do not require additional software installation.
