Increase Image Resolution: Convert Raster Images to Vector | MakeUseOf.com
Most of the digital images and pictures you see on the web are raster graphics images or bitmaps (.bmp). A raster graphics image is simply defined with a grid of pixels that are set to certain colors. Raster graphics images are resolution dependent and cannot be made larger without loss of apparent quality. Therefore, for images that need to be scaled to higher resolution often it is better to use vector graphics.

Images that are rendered using vector graphics will scale to any size and still maintain smooth edges. This is ideal for dealing with things such as fonts and logos. Inkscape is an open source vector graphics editor that you can use to convert raster images to vector graphic images.

I will demonstrate how to use Inkscape to convert the Inkscape logo above into an SVG (Scalable Vector Graphics) image. SVG is a vector graphics file format.

First of all you will need to download Inkscape and install it. It’s available for Mac OS X and Windows, and of course with the source you can compile it on Linux and other platforms as well.
