IconRules

IconRules

is an option for CloudObject and related objects that specifies icons to use in different environments to represent an object.

Details

  • The setting for IconRules can be the following:
  • imagea single image to be resized for all icons
    {image1,image2,…}images where an appropriate size is used for all icons
    {"env1"image,…}separate settings for different environments
  • Possible environments include:
  • "Android"icon to display under Android
    "FileBrowser"icon to display in the file browser
    "IOS"icon to display under iOS
    "WebPage"favicon for a webpage
    Allgeneric icon to use
  • The setting for each environment is of the form "env"->image or "env"->{image1,image2,…}.
  • When an icon of a particular size is required, the immediately larger imagei is selected and scaled down to the required size.
  • Each image can be an explicit Image object, Graphics, or any other expression, which if necessary will be rasterized.
  • A setting of Automatic for IconRules or for a particular element will generate an icon automatically from the contents of the cloud object.
  • If a particular element is needed that has not been specified explicitly, it will be interpolated from other elements given.
  • The setting for IconRules for a cloud object can be changed using SetOptions.
