  • ImageResolution is an option for Display and DisplayString which specifies at what resolution bitmap images should be rendered.
  • ImageResolution-> r specifies that a bitmap should be rendered at a resolution of r dpi.
  • ImageResolution is relevant only for bitmap graphics formats such as "TIFF", and not for resolution-independent formats such as "EPS".
  • The default setting ImageResolution->Automatic typically uses a resolution of 72 dpi for bitmap graphics formats.
  • See the Mathematica book: Section 1.11.5.
  • See also: ImageSize.
