I am a very new LaTeX user. I've searched all over and cannot find this
information. My question is, how does one retrieve the dimensions of an
Here's more explanation. For my first LaTeX project, I decided to create
customized local letterhead. I'm almost done.
But I'm using the graphix package to insert logos and such in the header
and footer. In general, I specify the image's width and let LaTeX set
the height using the aspect ratio. Even using \height or the calc
package's \heightof commands, LaTeX does not return the correct height
of the inserted graphic. (For example, with an aspect ratio of 0.5, a
graphic 2 inches wide should be 1 inch high, but these commands yield
numbers much smaller.) Yet I've read that all LaTeX does is calculate
the space the graphic needs, so it must have this information. It is
hard to believe since such information unavailable because it is
essential for custom page layouts.
Right now I enter graphic dimensions manually, messing with such things
as bounding boxes and viewports. There must be an easier way. What is it?
