I have about 100 eps/pdf drawings in my textbook on physics. They are produced mainly using Wolfram Mathematica and then edited in CorelDraw. I spent many hours of my time to match font size in the drawings with the text font size. Unfortunately, the publishing house has reedited my eps files. For some reason, which the publishing house cannot explain clearly (they just say that they always edit graphics themselves), they have changed the font in the graphic files, introduced lot of errors, so that I am really angry. StackExchange is not a proper place to list all my claims to the quality of their work, I just want to make sure that similar troubles will not happen in the future since I hope that it was not my last book.
I tried to draw the pictures (in CorelDraw) in the same scale as they should go to the book and use same font size as in the book.
Is the a better approach?
Could someone outline some rules on how to prepare a drawing in an external graphics programs to guarantee approximately same font size as in the main text of a book?
Is there a method to fix font size when scaling eps or pdf image in
Should the font size in a figure be the same as in the text or it should be smaller/larger?
