Since it is often desirable to get a good quality print on paper
directly from the browser, here areFigure showseq:pics15
the same equations as [page]earlieron page eq:pics.
This time the `extrascale=1.5' option has been used. This value of 1.5
means that more than twice the number of pixels are available,
for a cost of approximately 1.7 times the disk-space.
On-screen these images appear slightly blurred or indistinct.
However there can be marked improvement in the print quality,
when printed from some browsers; others may show no improvement at all.
The “anti-aliasing” helps on-screen. In the printed version
jagged edges are indeed softened, but leave an overall fuzziness.
Here areFigure showseq:pics2 the same equations yet again; this time with `extrascale=2.0'. Now there are 4 times the pixels at a cost of roughly 2.45 times the disk space. Compared with the previous images (having 1.5 times extra-scaling), there is little difference in the on-screen images. Printing at 300 dpi shows only a marginal improvement; but at 600 dpi the results are most satisfying, especially when scaled to be comparable with normal 10 pt type.
