Adobe公布的第一版Photoshop源代码,Photoshop 1.0.1版本于1990年推出,Zip文件夹内共有179个文件,代码总数为12.8万行。按行数计算,75%采用Pascal语言编写,15%为汇编语言,其余为其他种类数据。
这12.8万行代码主要由一个人编写,即Photoshop联合创始人托马斯·诺尔(Thomas Knoll)。诺尔是Photoshop 1.0.1的唯一一名工程师,在发布第二版软件时,才招聘了第二名编程人员。
诺尔拥有密歇根大学计算机系博士学位。他与自己的兄弟约翰·诺尔(JohnKnoll)共同开发了Photoshop。这款软件的早期名称是“Display”,最终更名为“Photoshop”,并于1989年授权给Adobe,Photoshop 1.0.1就在第二年发布。
源码在跟 Adobe 有合作关系的计算机计历史博物馆展出。
