Specifies to which tab or window the value should be set, or from which one it should be retrieved. If no tab nor window is specified, the global value is set or retrieved.

imageData? path? tabId? windowId?
imageData?: ImageData | { [key: number]: ImageData }

Either an ImageData object or a dictionary {size -> ImageData} representing icon to be set. If the icon is specified as a dictionary, the actual image to be used is chosen depending on screen's pixel density. If the number of image pixels that fit into one screen space unit equals scale, then image with size scale * 19 will be selected. Initially only scales 1 and 2 will be supported. At least one image must be specified. Note that 'details.imageData = foo' is equivalent to 'details.imageData = {'19': foo}'

path?: string | { [key: number]: string }

Either a relative image path or a dictionary {size -> relative image path} pointing to icon to be set. If the icon is specified as a dictionary, the actual image to be used is chosen depending on screen's pixel density. If the number of image pixels that fit into one screen space unit equals scale, then image with size scale * 19 will be selected. Initially only scales 1 and 2 will be supported. At least one image must be specified. Note that 'details.path = foo' is equivalent to 'details.imageData = {'19': foo}'

tabId?: number

When setting a value, it will be specific to the specified tab, and will automatically reset when the tab navigates. When getting, specifies the tab to get the value from; if there is no tab-specific value, the window one will be inherited.

windowId?: number

When setting a value, it will be specific to the specified window. When getting, specifies the window to get the value from; if there is no window-specific value, the global one will be inherited.
