Can SVG contain raster images?
Much like the img element in HTML SVG has an image element to serve the same purpose. You can use it to embed arbitrary raster (and vector) images.
Why does an SVG scale better than raster graphics?
Scalability. One the major benefits of SVG is that they are resolution independent. This means that unlike file types such as JPG or PNG, SVGs retain the same quality no matter what screen resolution or size they are being at.
Can SVGs be malicious?
SVG files can also contain embedded JavaScript (JS) code, a potential vulnerability. For example, an infected SVG file can redirect users to a malicious website disguised as a reputable one. These sites often prompt users to install spyware disguised as a browser plugin or, ironically, a virus detection program.
Can a raster image be generated from SVG?
For basic SVG, the quality of the Batik rendering is quite high, and is particularly appropriate for generating images in raster formats such as PNG or JPEG from SVG graphics. Batik supports nearly all features of SVG 1.1, but has not implemented CSS3 features which you might wish to use in SVG for modern web browsers.
How is the size of an SVG image determined?
The size of simple SVG files is defined by the colors, layers, gradients, effects, and masks that it contains. The size of a PNG or any other raster graphics file is defined by the number of pixels that it consists of. The larger a PNG image is, the heavier it gets in size. This is not the case for SVG icons, though.
Why are SVG images used in graphic design?
As vector images, SVGs are composed of mathematical equations that define the positioning and color of lines and curves which make up graphic shapes and text in XML format. SVGs are used for icons, logos, graphic designs, and fonts.
Do you need a snapshot of an SVG image?
Although we’d love to have SVG everywhere, you often need a “snapshot” image of an SVG, saved in a common raster (aka, bitmap) image format, such as PNG or JPEG. These SVG snapshots are your fallback images for old browsers, and are often required as thumbnail or preview images, particularly for social media sharing.
