Constants

 
 "Disposal" method indicates how the image should be handled before the
  subsequent image is displayed.
  Don't change these without looking at the implementations using them,
  struct gif_struct::disposal_method and gif_write() in particular.

const long kBlendOver = 1

 Animation mode Constants
   0 = normal
   1 = don't animate
   2 = loop once

Attributes

attribute unsigned short animationMode

 Get the current frame that would be drawn if the image was to be drawn now

readonly attribute gfxIImageFrame currentFrame

Methods

[noscript] void addRestoreData([const, array, size_is(aCount)] in char data, in unsigned long aCount)

 Adds \a item to the end of the list of frames.
 @param item frame to add.

void appendFrame(in gfxIImageFrame item)

void decodingComplete()

void endFrameDecode(in unsigned long framenumber)

gfxIImageFrame getFrameAt(in unsigned long index)

 Create a new \a aWidth x \a aHeight sized image container.

 @param aWidth The width of the container in which all the
               gfxIImageFrame children will fit.
 @param aHeight The height of the container in which all the
                gfxIImageFrame children will fit.
 @param aObserver Observer to send animation notifications to.

void init(in PRInt32 aWidth, in PRInt32 aHeight, in imgIContainerObserver aObserver)

void resetAnimation()

[noscript] void restoreDataDone()

[noscript] void setDiscardable(in string aMimeType)

void startAnimation()
