Rendition service

Supported formats

The ImageMaster rendition service is internally used by the WorkplaceClient for several actions concerning document previews, like the following:

  • to detect the format based on the MIME type

  • to display a preview in the integrated viewer

  • to print a rendition of the content of a document

  • to generate and display thumbnail images

The rendition service supports the following formats:

  • BMP

  • CSV

  • GIF

  • HTML

  • JPG

  • Mails (MSG, EML)

  • Microsoft Excel (XLSX, XLSM, XLS)

  • Microsoft Powerpoint (PPT, PPTX) – currently disabled in the client

  • Microsoft Word (DOC, DOCX, DOTX, DOCM)

  • OpenDocument Spreadsheet (ODS)

  • OpenDocument Text (ODT)

  • PNG

  • RTF

  • Text (Plain, XML, CSS, CSH, JS, SH, TEX)

  • TIFF

The following 2D CAD formats are supported:

  • CGM

  • DGN

  • DWF

  • DWG

  • DWT

  • DXF

  • IGS

  • PLT

  • SVG

Thumbnail processing

For better performance a thumbnail can be integrated into an ImageMaster document (per content object in a revision). If no thumbnail is integrated, the service generates one on the fly from one of the supported formats listed above.

The rendition service checks if a thumbnail is integrated in either of these ways:

  • by an additional file (binary object) with the content property “ima:client:thumbnailOf”

  • by an additional file with the file extension “.thumb”

    If both of the above are present, the file marked with the property is selected.

The recommended formats to use for integrating a thumbnail are JPG and PNG. (Also supported but not recommended are BMP and GIF.)

Instead of the above internal processing, the whole mechanism can be replaced by a customer-specific solution.
