I am looking for a free tool (Windows/Linux) which can display a PDF and show the coordinates under the mouse pointer in millimeter (or inch/etc just what the settings are) based on the PDF coordinate system. It would be nice if it comes with a zoom function for extra precision.
Background is that I want to check (pdflatex) placement of objects in the PDF output.
I found this StackOverflow thread however the answers are not free tools (Illustrator) or pixel based solutions (GIMP), etc.
Since version 3.0 you can do that with Sumatra PDF.
Just tested it. Works great. Changelog said:
added a document measurement UI. Press ‘m’ to start. Keep pressing ‘m’
to change measurement units
You’ll find the UI appearing in a box on the top left. Units are mm, in, pt.
Have fun meassuring.
