That was intended, yes, the manual should probably have said "The
background color given will be ignored if there is a background color
\special in the DVI."
"Transparent" doesn't change the background color, it enables the
alpha channel.
The actual background color (visible, say, in a reader without the
alpha channel) is controlled by the color spec, and overridden by a
color \special.
Thank you for your reply and the explanation.
Did you want this to work differently, or was the problem that you
were surprised by the behavior?
Some time ago, a change in org-mode (emacs package) introduced a bug
because this behavior was unexpected.
Org-mode uses latex > dvipng to generate images to be included in an
emacs buffer. If the user specifies a background color, it is set using
the latex commands, otherwise the image should be transparent.
I assume there's no way to get dvipng to behave like this ?
