From e3e8ce08a6adeab415885c8da2a629a205bfe6ae Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Tue, 6 Sep 2016 12:27:58 +0200 Subject: Add script which scales splash screen down Based on reading documentation around. This particular version is based on the ImageMagic documentation which could be found there: http://www.imagemagick.org/Usage/filter/ http://www.imagemagick.org/Usage/filter/nicolas/ Current filter is based on measuring mean error with the current splash screen and choosing combination of parameters which gives minimal mean error. --- release/datafiles/splash_scale.sh | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100755 release/datafiles/splash_scale.sh diff --git a/release/datafiles/splash_scale.sh b/release/datafiles/splash_scale.sh new file mode 100755 index 00000000000..8a3f2c6d1eb --- /dev/null +++ b/release/datafiles/splash_scale.sh @@ -0,0 +1,18 @@ +#!/bin/bash + +# Use this script to generate splash.png from splash_2x.png. +# Supposed to give best quality image. +# +# Based on ImageMagic documentation, which is interesting +# to read anyway: +# +# http://www.imagemagick.org/Usage/filter +# http://www.imagemagick.org/Usage/filter/nicolas/ + +convert \ + splash_2x.png \ + -colorspace RGB \ + -filter Cosine \ + -resize 50% \ + -colorspace sRGB \ + splash.png -- cgit v1.2.3
