SVG graphics are vector
graphics, so they can be resized without losing quality. A single
SVG file can be scaled to any size or transformed to any resolution
without compromising the clarity of the graphic. Bitmap images such
as PNG and GIF lose quality any time they are resized.
Also, if you need to
display the same graphic at multiple sizes or resolutions, you would
need multiple bitmap images, but only one SVG file. SVG files display
clearly at any size in any viewer or browser that supports SVG. Using
browser controls, the user can zoom in to view details in a complicated
SVG graphic.
An SVG file might also
be smaller in size than the same graphic created by a bitmap (image)
device such as GIF or PNG.
SVG files are ideal
for producing any documents of any size to display on a computer monitor,
PDA, or cell phone, or documents to be printed or delivered as PDFs.
