Introduction

Reconnect includes assets extracted from the original PsiWin and PsiMac software to try to maintain the original 90s feel of using these devices. Extraction was performed using a combination of 7-Zip, FFmpeg, and ImageMagick.

These images remain the copyright of Psion PLC.

Extraction

Dependencies

I prefer to use Homebrew to install the dependencies:

brew install ffmpeg imagemagick p7zip

Animations

PsiWin includes a number of AVI files that are used to indicate on-going progress. These need to be massaged to work with Reconnect:

1. Generate separate animations from the original AVI files using FFmpeg:

   ffmpeg -i SYNC.AVI "frame%04d.png"
   

2. Combine those frames into a GIF using ImageMagick for use in Reconnect:

   # 1x
   convert \
       -delay 0 \
       -loop 0 \
       -alpha set \
       -dispose previous \
       -transparent "#00ffff" \
       *.png \
       sync.gif
   
   # 2x
   convert \
       -scale 200% \
       sync.gif \
       sync@2x.gif
   

This functionality is provided in scripts/convert-avi.sh.

For example,

scripts/convert-avi.sh --transparency "#00ff00" SYNC.AVI .
