Background color #157
I am trying to make slides with a black background.
Following the documentation the .ipe file contains
<symbol name="Background" transformations="translations" xform="yes"> <path stroke="black" fill="black"> -32 600 m -32 0 l 768 0 l 768 600 l h </path> </symbol>
The 'trick' of adding a layer named "BACKGROUND" and setting it invisible to not display the background (as written in the wiki does not work with Ipe 7.2.7).
The doc mentions the visible/invisible checkbox to show/hide the background.
Hi @otfried. I just gave the talk featuring slides with a black background.
cp white-background-slides.ipe black-background-slides.ipe xml ed --inplace -u "/ipe/ipestyle/color[@name='special']/@value" -v '1 1 1' -d "/ipe/page/layer[@name='BACKGROUND']" black-background-slides.ipe ipetoipe -pdf black-background-slides.ipe
It does update (-u) the color with attribute 'special' and sets it to white.
