public final void <B>setFormat</B>(java.lang.String&nbsp;format)</PRE>
<DL>
<DD>Sets the picture format to <tt>format</tt> for the picture to be read or
written.
<p>
It is necessary to specify a format before writing an picture, but
it is not necessary to specify a format before reading an picture.
<p>
If no format has been set, Qt guesses the picture format before
reading it. If a format is set the picture will only be read if it
has that format.

public final void <B>setParameters</B>(java.lang.String&nbsp;parameters)</PRE>
<DL>
<DD>Sets the picture's parameter string to <tt>parameters</tt>. This is for
picture handlers that require special parameters.
<p>
Although the current picture formats supported by Qt ignore the
parameters string, it may be used in future extensions or by
contributions (for example, JPEG).
