I understand your wish to test in the worse case, but really, people are able to choose their resolution with gfxboot, powerpc automatically choose the right resolution, CRT screen doubles neither row nor column, LCD have smooth scaling for years. However, i build 1024x768 picture with same colors using convert. I published them as *.1024x768.png at http://bersace03.free.fr/pub/ubuntu/dapper/usplash/ . I use my updated Makefile i attached to build all these 8 picture easily. Put you source pngs in [EMAIL PROTECTED] in the PNGS variable. Then Type make 1024x768 and it will build .1024x768.png pictures. type make 640x400 and the same appear for 640x400. make thumbs generate thumbs from 640x400 resized to 320x240. make build .so for each PNGS. make install to copy them to /usr/local/lib/usplash and add alternative for these. No uninstall target yet :). Wish that helps. Étienne. -- Verso l'Alto !
#
# This Makefile consists of a bunch of rules to automate the task of splashes handling.
# You need imagemagick libbogl-dev gcc and other packages to get this work.
#
# 1. Build .png to .so
# 2. Generate 640x400 from 640x480
# 3. Generate thumbnails from 640x400 resized to ration 4:3
# 4. Resample to 1024x768 without antialias
# 5. Install .so in /usr/local/lib/usplash and add alternatives.
