Nice find. Here’s a quick summary of the content (as I read it):
– Vectors are paths (points+curves which is good for logos & fonts) – Rasters are pixels (boxes-on-grid which is good for photos)
– Vectors = points + math (how CAD programs work)
– Rasters = bitmaps = pixels = grid (how computer monitors & TVs work)
– Vectors (connect-the-dots) formats are eps, ai, FHx, etc. – Rasters (pixels-on-a-grid) formats are tiff, pict, jpeg, bmp, etc.
– Vectors are upward scalable and provide clean lines
– Rasters don’t scale well (interpolate) & provide jagged line edges (pixelate)
– Vector quality does not change based on size
– Raster quality is determined by size & resolution (2400 x 1600 @ 300 dpi)
– Vector curves that complete can be colored inside
– Raster boxes have a numerical value for color
– Vectors are good for sharp line graphics at any size
– Raster is good for print images & web at a small size
– Vectors are smaller and edit faster
– Rasters are bigger and edit slower
– Vectors scale up perfectly
– Rasters scale up pixelated
– Vector curves can be assigned any color (whether solid or gradient) – Raster boxes are limited in color assignments (yet are more lush)
– Illustration editors are (mostly) vector based (e.g., Inkscape, Illustrator) – Photo editors are (mostly) raster based (e.g., Irfanview, Photoshop)

QUESTION: What’s the advantage of this trace being a vector diagram?http://www.graphicdesignforum.com/forum/showthread.php?t=41
