bitmap or vector?

When at work, Steve often requests for a company’s logo and is sent one that’s readily available—usually from their website. Sadly, it’s a low resolution/blurry one as opposed to a sharp one. This is because there’s, sometimes, confusion between available computer formats for logos, etc.

the difference in formats :

1 a bitmap/raster file is composed of pixels e.g. .tif/.bmp/.jpg (all bitmap or pixelated files), and …

2 a vector file, composed of paths or lines—for example,
an Adobe Illustrator eps*.

here’s the thing to remember …

If you enlarge a bitmap/pixelated file of, for example,
ajlogo, it will be blurred beyond belief.

However, if you enlarge a vector/line file of the same logo to 50 km wide (or even 3 billion light years wide) it will still be sharp … it is based on geometrical formulas to render the file, resulting in line.

Use whichever suits your needs best e.g. bitmap for web that’s low resolution, but vector for sign-writers or anyone creating artwork.
