doubles for their color components. In contrast to

read-only access.<p>
Use this interface for e.g. bitmaps that are calculated
on-the-fly, or that are pure functional, and thus cannot be
modified.<p>
If you get passed an instance of
<type>XHalfFloatReadOnlyBitmap</type> that also supports the
<type>XVolatileBitmap</type> interface, things become a bit more
complicated. When reading data, one has to check for both
<type>VolatileContentDestroyedException</type> and mismatching
<type>FloatingPointBitmapLayout</type> return values. If either of them
occurs, the whole bitmap read operation should be repeated.<p>
