Learn in the textbookFile Formats for Still Images and Documents
DefinitionEPS is a file format that describes graphics and images in PostScript, a page description language (ページ記述言語) for printing, so they can be placed inside other documents.
ExplanationA page description language expresses where on the page to draw what, and how, as a series of commands, and PostScript was developed by Adobe. When shapes are drawn in vector form, as coordinates and commands, their outlines stay clean however far they are enlarged. In DTP (desktop publishing), it has long been used to place illustrations and logos onto printed pages.
AnalogyIt is like a set of drawing instructions that says "draw a circle with a 3 cm radius from here." The reader does the drawing, so the lines stay crisp even on a large sheet.
Memory hookIt stands for Encapsulated PostScript, and Encapsulated (sealed in a capsule) reflects its job as a component dropped into other documents.
