SignMatic Application Package is a distribution file format for the open Digital Signage System SignMatic. The File-Package contains all necessary information for a application to be installed on a local system.

Overview

SignMatic Application Packages are encoded file archives with a variable size header, encoded bitmap image of the Application icon and various metadata. The files are opened by the system utility smdepak (console application) or smdepakw (User Interface), that performs various compatibility checks including versioning, downgrade and upgrade options as well as the actuall unpacking and registration of the application to the signmatic applications directory.

Technical

The File size is not limited to a certain size, the header size however must be in the range of 196 to 4096 bytes, given the fact that for the necessary metadata this is absoloutely sufficient.

The File consists of the Magic Sequence 0x16 0x0F 0x17 0x1B followed by literal SignMatic

Generation

SignMatic Application Packages can be created using the command line tool smpak (delivered with SignMatic Studio). The application folder requires a valid build information file (example below) to be present in the base directory named "build".
