zoom in picture environment hp50g

[emmo0]

When I try zoom in plot environment, I have no problem, but when I try it in picture environment I can't do it.

I think it can not be done, but perhaps I'm wrong.

Any idea?

Thank you in advance.

Zooming a plot in HP48/49/50
does not mean zooming a current image,
but instead means re-plotting,
after modifying some plotting parameters.

I can't even find calc software for image resizing
at www.hpcalc.org, although you can convert HP "grobs"
to image files which can be re-sized on computers,
and perhaps vice versa.

Resizing pixel-based images of any kind is generally "lossy,"
and would mean you could not recover the original image
unless you always saved the unprocessed original;
all considered, this may require more memory and
processing power than resided in these calculators.
