What are bitmaps and PICTs?
Dear Shannon: A bitmap uses a raster graphics format, while a PICT uses a vector format. Bitmaps define an area by scanning each row of pixels and noting where there is a change in color, whereas a PICT accounts for each individual pixel’s color. Bitmaps are simpler formats to save graphics in, so graphic designers usually create graphics in a vector format, then save them as bitmaps. The Indiana University Knowledge Base Web site at http://kb.indiana.edu/data/afmr.html explains more about raster and vector graphics.
