I’m using PTXPrint 1.8.1. I have been trying to improve the default layout on some pages by working with the adjustments list to stretch or shrink paragraphs.
My question is – How does PTXPrint decide on whether to apply requested adjustments to the layout. My current experience is that I can request a longer (+1) or shorter (-1) paragraph, but whether or not PTXPrint (TeX) applies that request is trial / error.
I’m sure that the spacing adjustments parameters given will have a big impact on whether the +1 or -1 can actually be obeyed. But, in numerous cases I am trying to shrink a paragraph which has a short last line, has more than 10 lines of text, and appears to have room for adjustment, but the shrink request with -1 at the appropriate reference has no effect.
What other factors are involved in understanding how PTXPrint decides whether to apply an adjustment, or not?
