public abstract int checkImage( Image image,
int width,
int height,
ImageObserver observer )
Parameters
- image
- the image whose status is being checked.
- width
- the width of the scaled version whose status is
being checked, or -1.
- height
- the height of the scaled version whose status
is being checked, or -1.
- observer
- the ImageObserver object to be
notified as the image is being prepared.
Returns
the bitwise inclusive OR of the
ImageObserver flags for the
image data that is currently available.
Description
Indicates the construction status of a specified image that is
being prepared for display.
If the values of the width and height arguments are both
-1, this method returns the construction status of
a screen representation of the specified image in this toolkit.
Otherwise, this method returns the construction status of a
scaled representation of the image at the specified width
and height.
This method does not cause the image to begin loading.
An application must call prepareImage to force
the loading of an image.
This method is called by the component's checkImage
methods.
Information on the flags returned by this method can be found
with the definition of the ImageObserver interface.
