I have the following problem. While earlier I succeeded to create EPS/PDF figures with LaTeX command (a specific file feynman. sty), and each picture was of a normal size, now something changed in LaTeX in a new version of TexStudio, and the EPS/PDF figure occupies an entire page. fourpoint.pdf Using Linux-like style of LaTeX through terminal (which earlier helped to solve this problem on Mac computers) now also does not help. Thus, the question is -- how to obtain a small-size image in LaTeX?
The situation became much more simple. Actually, after starting the Terminal command as usual, I processed the TEX file (latex *.tex), then converted DVI to PS as usual (dvips *.dvi), and then, used the simple command ps2eps *.ps. And the problem is solved! By the way, I am grateful to all of you for calling my attention to extra programs for designing Feynman diagrams, for example, https://www.aidansean.com/feynman/. Thank you very much again!
