Careful, the source PNG embedded in the ODF archive is sized 473 x600 x 24 BPP.
It will be scaled to place on a canvas you've defined (here 8.5 x 11 inches of
the cover). So the loss of detail is the resampling that has to occur to expand
the pixel count--nearest neighbor, bilinear, bicubic--I don't know which gets
used, just that a resampling occurs, and can appear fuzzy. Very noticeable on
the pillow tassel.
To compare "apples to apples" for image quality on export the Draw page/canvas
size would have to be set to the size of the image.</pre>
