Width of lines connecting Simulink blocks

Dear All,

I would like to export Simulink models (generated by a Matlab code) into png format. However, the width of the lines connecting the various blocks (created with add_line) is too thin when exported with high-enough resolution (e.g. 300 or 600; increasing the resolution "causes" lines to "get thinner").

Is it possible to modify this line width from code?

Any help would be most welcome!

Apparently, it is impossible to do so in Matlab or Simulink. However, after generating the graphics file one can apply external softwares to thicken the lines. E.g.:

(Not a solution to thicken individual lines but it solved my problem.)
