I modified the two files, replaced them in my 6.2.1 installation, and ran raco setup.
I created a simple test slide, and it beautifully filled my 2560x1440 screen, which has the same aspect ratio (16x9) as HD 1080p. That’s a rather static solution, however. One that embeds the aspect ratio in the presentation would be much preferable. Since 16x9 is such a common aspect ratio, a #lang slideshow/widescreen with that aspect ratio built in would be useful, but is beyond my Racket skills (I haven’t created a #lang yet). But perhaps we can just parameterize screen-w and screen-h? Would that require more than a pass through the source code to change the variables screen-w and screen-h to parameter calls (screen-w) and (screen-h)? > On Oct 19, 2015, at 1:23 PM, Byron Davies <byrondav...@starshine.us> wrote: > > Since it hasn’t already been done, I thought it might be more complicated > than just changing two numbers.
