updateData
Updates image data that is accessed by reference. This method calls the updateData method of the specified ImageComponent2D.Updater object to synchronize updates to the image data that is referenced by this ImageComponent2D object. Applications that wish to modify such data must perform all updates via this method.The data to be modified has to be within the boundary of the subregion specified by the offset (x, y) and the dimension (width*height). It is illegal to modify data outside this boundary. If any referenced data is modified outisde the updateData method, or any data outside the specified boundary is modified, the results are undefined.
- Parameters:
updater
- object whose updateData callback method will be called to update the data referenced by this ImageComponent2D object.x
- starting X offset of the subregion.y
- starting Y offset of the subregion.width
- width of the subregion.height
- height of the subregion.- Throws:
CapabilityNotSetException
- if the appropriate capability is not set, and this object is part of a live or compiled scene graphIllegalStateException
