The results of data post-processing are typically compiled in an automatically generated report. Tools that generate such reports use a description file that defines the layout of the reports. ASAM LXF standardizes the layout format description so that it can be defined once for a specific report and then shared among different reporting systems. This reduces the effort to maintain layout descriptions to a minimum and ensures that reports of the same type look the same, even though they have been created by different tools.

ASAM LXF (Layout Exchange Format) defines an XML-based format for describing layouts for graphical content used by data post-processing applications and automated document generators. A layout description contains the definition of a master layout, canvases, page formats, fonts and colors. The master layout determines the general page design, e.g. by specifying a header and footer, which are used on all pages. A page may contain just one canvas or a matrix of canvases. A canvas defines a drawing area and contains a set of graphical elements, such as images, lines, ellipses, rectangles, charts, tables or text. Elements can be grouped in one container. The XML format may contain embedded formulas that are resolved during runtime.

ASAM LXF is harmonized with and typically used in conjunction with ASAM CEA, which produces the content for generated reports.
