  • "AudioOutput" will convert to any of the built-in "Audio Formats".
  • "DateFormat" can be a format or a function.
  • Possible settings for "GraphicsOutput", "Graphics3DOutput", and "MathOutput" are:
  • "CDF"converts the targeted expressions to embedded CDF
    "DisplayForm"converts the targeted expressions to ASCII approximations of their appearance
    "GIF"converts the targeted expressions to GIF
    "InputForm"converts the targeted expressions to their InputForm

    "JPEG"converts the targeted expressions to JPEG
    "SVG"converts the targeted expressions to SVG
  • "MathOutput"->"MathML" or "MathOutput"->"TeX" will convert all typeset expressions to MathML or TAdjustmentBox[E, BoxBaselineShift -> 0.5, BoxMargins -> {{-0.3, 0}, {0, 0}}]X, respectively. JavaScript will also be added if "FullDocument" -> True.
  • "NumericFormat" can be a list of rules or a function.
  • Possible settings for "RenderFormat" are:
  • "HTML"render as HTML
    "Bootstrap"render as HTML with embedded "Bootstrap" classes
  • On a web server, files are deployed into "StaticRoot" and mapped with "StaticPrefix".
  • Possible settings for "URLHandler" are:
  • Automaticconverts generated URLs to data URIs if the data is sufficiently small, otherwise exporting to temporary files on disk
    "CloudPut"converts generated URLs to data CloudObjects
    "DataURI"converts generated URLs to data URIs
