Richard,Fluid said:actually eps can be both a vector or raster image.
baumwolle said:it's more a factor of the application that you are using to create the files.
photoshop can save eps files BUT they are not vector.
illustrator, freehand, and other drawing apps are used to make vector eps files.
I think if you are CREATING a graphic in inkscape (or corel or illustrator) and the original design ORIGINATES in the vector software and is saved as EPS, then it will be a vector file.I downloaded the inkscape software (I believe it's in the list of the drawing apps, like you mention below); now when I save a file in it indicating eps extension, that means it's vector.
