storeOffline(onComplete, onProgress)

[XOD Document only] Downloads the document for offline viewing.

Parameters:

Name	Type	Description
`onComplete`	function	The function that's called when the document has finished being downloaded or the download has been cancelled
`onProgress`	function	The function that's called on each update in progress of the download. The fraction downloaded is passed as a parameter. (eg 50% downloaded passes 0.5)

trigger(type [, data])

Calls the handlers of the event name with given data

Parameters:

Name	Type	Argument	Description
`type`	string \| number		event name of which the handlers will be called.
`data`	*	<optional>	data that will be passed to the handlers. If data is an array, it will be spread and then passed to the handlers

Inherited From:

Core.EventHandler#trigger

Returns:

Returns the object that 'trigger' is being called on

Type: object

Example

myObject.trigger('eventName');
myObject.trigger('eventName', [eventParameter1, eventParameter2]);

unloadCanvasResources(id)

Unloads resources for the page associated with the loadCanvasAsync call corresponding to the passed in id. So if the loadCanvasAsync call had requested page 2 then page 2's resources will be cleaned up (as long as nothing else requires those resources). Note that the canvas element itself is not touched.

Parameters:

Name	Type	Description
`id`	number	The id returned from the loadCanvasAsync call that will have it's page resources unloaded

unloadResources()

Cleans up the resources associated with the document.

updateRasterizerOptions(options)

Object

Options for this function

Properties

Name	Type	Argument	Default	Description
`pageTransparent`	boolean	<optional>	false	Page background transparency.
`overprintMode`	number	<optional>	Core.OverprintPreviewMode.PDFX_ON	Enable or disable support for overprint and overprint simulation.
`antiAliasing`	boolean	<optional>	true	Enable or disable anti-aliasing.
`pathHinting`	boolean	<optional>	true	Enable or disable path hinting.
`thinLinePixelGridFit`	boolean	<optional>	false	If true (horizontal/vertical) thin lines will be snapped to integer pixel positions.
`thinLineStrokeAdjust`	boolean	<optional>	true	Enable or disable auto stroke adjustment.
`imageSmoothing`	boolean	<optional>	true	Enable or disable image smoothing.
`hqImageResampling`	boolean	<optional>	false	Whether use a higher quality (but slower) smoothing algorithm.
`caching`	boolean	<optional>	true	Enables or disables caching. Caching can improve the rendering performance in cases where the same page will be drawn multiple times.
`expGamma`	number	<optional>	-1.0	The gamma factor used for anti-aliased rendering. It is the exponent value of gamma function. Typical values are in the range from 0.1 to 3.
`colorPostProcessMode`	number	<optional>	Core.ColorPostProcessMode.NONE	Set the color post processing transformation. This transform is applied to the rasterized bitmap as the final step in the rasterization process, and is applied directly to the resulting bitmap (disregarding any color space information). Note that this option has no effect when using Core.OverprintPreviewMode.SEPARATION_RENDER.
`renderAnnots`	boolean	<optional>	false	Enable or disable annotation and forms rendering (In the viewer, annotation rendering is done separately).
`highlightFields`	boolean	<optional>	false	Enable or disable highlighting form fields. This option only has an effect when renderAnnots is true.
`isPrinting`	boolean	<optional>	false	Tells the rasterizer to render the page 'print' mode. Certain page elements (such as annotations or OCG-s) are meant to be visible either on the screen or on the printed paper but not both. A common example, is the "Submit" button on electronic forms.
