RMagick Documentation about interline_spacing mentions - "A numeric value. If positive, inserts additional space between lines. If negative, removes space between lines. The amount of space inserted or removed depends on the font."
There could be an alternative to fix the line-height at the client but there doesn’t seem to be any working equation with the interline spacing.
What could be the possible implementable approaches to address the problem of interline spacing so that one can get the exact text appearance rendered out of RMagick as was entered by the user.
