Hello, I am designing a typeface and I would like to be able to adjust the line spacing to keep it to a minimum and when exporting the typeface it continues to work with the minimum line spacing in the design softwares. Initially I tried to reduce the height of capitals and descendents but it didn’t work. Could someone help me? considering that I know almost nothing about phyton 
Thank you guys!
