History

Smile was first released in 1995 as SMILE (in upper case). The acronym stood for ''SMI, Limited Edition'', with SMI standing for ''Scriptable Measurements on Images''. SMI is a software developed by Satimage Software, a French company engaged in

technology, to automate real-time measurement and inspection systems for industrial plants. SMI is the core engine, which is written in C/ C++ that alone does nothing: it requires an interface, and that interface's behavior is programmed in

. SMI's core implements the key features of the software and publishes them to

. Basically, Smile is just SMI, without real-time video processing features. The need for 2D and 3D real-time visualization (of the measurements) gave rise to SmileLab. More recently, web-based control of facilities has become a standard, and Smile is now also a web applications server and a

SmileLab

Smile provides an Aqua interface to make any data graph "manually" and libraries of commands to make graphs and process data via scripts (SmileLab can display at any moment the script corresponding to the user's action.)

Performance

Computational extensions can be written in C or C++. Smile handles common file formats, but extensions for unsupported file formats can be added.

Smile Server

Smile Server is a bridge between a CGI program and

. This works by Smile opening a server port. A specific CGI, included, makes an HTTP request into a p-list (Apple's associative array XML format) and sends it to Smile Server on that port (specified in a configuration file). Asynchronous as well as synchronous behaviours are implemented, allowing Smile Server to be used as an alternate solution to .asp or .php to build dynamic sites, including
