Hello Mathematica NG:

?>>> How can I export plots I make in M4 to BMP format and get a picture
that has the _size_ I want (say x in by y in) AND the _resolution_ I
want (say 400 dpi)?

>>> I read the help file on ImageSize, ImageResolution etc., but I find
it very confusing (e.g., where does the 72 in ImageSize come from?). It
would be a great idea if Wolfram could add an example here that does not
use EPS (resolution independent) but BMP and explicitly show the
settings for the image resolution and how to change them.

>>> the M4 Help file still states the M3 command instead of the M4
"Export" command.

>>> Also: opening any of the BMP files in some editing software always
results in these huge images - but I assume that's because the software
shows every single point of the file instead of scaling it down to
monitor size?

Many thanks,
