という訳で、Painter のWindows版のpreviw.pixの内容を
Appleのサイトの情報を参照しながら詳細に解析しますと、
１ピクセル・ラインごとにRun length encodingで圧縮された32ビット
（24ビットカラー）のピクセルマップデータであることが判りました。

Run length encodingは同じデータが複数回出現した場合、
そのデータを並べる代わりに回数を記述する、ことを基本とした
圧縮方法の総称ですが…
PICTファイルでの圧縮の詳細は発見できてません(^^;;
…が、適当に規則的なファイルを使うことで解析可能かと。。。？

ちなみにPainter のMac版のプレビューデータは圧縮無しの32ビットデータでした。
（下記のデータのpackTypeが$0001）
