.STL Estensione file

Game file used by SuperTux, a 2D jump and run side scrolling game similar to Super Mario Bros.; saved in a plain text format and specifies the features of a level, such as enemy unit locations, positions of blocks, and the time limit; also includes a reference to the music and background image for the level.

STL files are stored in the /​data/​levels/​ directory of the installation.

List of predefined items that have been signed by a trusted entity; may consist of a list of filenames or a list of certificates; each item in the list has been approved by the signing entity.

Certificate trust lists (CTLs) are used by Microsoft IIS to store trusted websites and other addresses that require a secure connection.

Library of styles referenced by Macromedia (now Adobe) Fireworks; may be used to apply Stroke, Fill, Effect, and Text attributes to an object within an open Fireworks project; can be helpful for creating a uniform look across multiple objects.

Some styles are included with Fireworks, though additional styles may be added to the program. To add extra styles, click the small icon in the top right corner of the Styles panel in Fireworks and select "Import Styles." Then browse to an STL file and click OK to add the style library to your current collection.

An STL file is a subtitles file saved in the European Broadcasting Union (EBU) subtitle data exchange format. It contains binary data used to load subtitles and store subtitle metadata. STL files are used mostly to provide subtitles during TV broadcasts.

In 1991, the EBU published specifications for the STL subtitles format. STL files contain a set of subtitle texts and information, such as time codes and positioning, used to display that text during a broadcast. The files also contain metadata that defines the subtitles' publisher, editor, and country of origin.

Unlike many other types of subtitle files, STL files are binary files, so you cannot view or edit the text they contain in a text editor. Some broadcasters still use the STL format, but the format has largely been replaced by the newer, XML-based EBU-TT format.

You can open an STL file with EZTitles (Windows) or Avid Media Composer (Windows, Mac). These programs allow you to import STL files and use them as subtitle tracks while creating a video. You can also view the subtitles and metadata an STL file contains with Jongbel Media Solutions EBU STL Viewer (Windows).

You can use Jongbel Media Solutions EBU STL Viewer (Windows) or EZConvert (Windows) to convert STL files to many other subtitle formats, including:

• .SRT - SubRip Subtitles
• .ASS - Aegisub Advanced SubStation Alpha
• .PAC - PAC Subtitles
• .VTT - Web Video Text Tracks
• .SUB - MicroDVD Subtitles
• .890 - Cavena Subtitles
• .USF - Universal Subtitles Format
