We can reproduce this problem and will have a fix in
ImageMagick 6.2.8-3 Beta
within a day or two.  Thanks for the problem report.

And for the 2nd problem? I.e. obtaining a PS/PDF of the same
size of the bitmap at the given resolution
but in the specified papersize? Will the patch fix also this
problem?

Bye
Giuseppe.

I tried 6.2.8-3, with the same examples as before, but I
get, e.g.:

convert -page A4 -units PixelsPerInch -density 300
test300.png test300.ps

%%BoundingBox: 0 0 143 143
%%HiResBoundingBox: 0 0 142.8 143
%%PageBoundingBox: 0 0 143 143

Where the number 143 is calculated from? It corresponds to
1.98 inches
instead of 1 inch (300 pixels at 300 dots per inch should be
1 inch). Furthermore in the 
HiresBoundingBox there should be some rounding problems.
Using the 1200x1200 pixels
picture, the size in the PostScript page would remain the
same, i.e.:

%%BoundingBox: 0 0 143 143
%%HiResBoundingBox: 0 0 142.8 143

instead of 4 inches, i.e. 288 288 big points. Is this the
right behaviour?

Thanks
Bye
Giuseppe.
