      public Image getImage(byte[] data, boolean errorImage)
      convert the given data to an image
      Parameter:
      data - the data which forms the image (as aquired from the blob field)
      errorImage - if true return the error image, otherwise return null in case of errors
      Gibt zurück:
      the resulting image or null / an error image if some problem is encountered

    • getWidthRenderingFactor

      public double getWidthRenderingFactor()
      Gets the property 'width rendering factor'. While 'width scaling factor' is a user defined faction this rendering factor includes the user factor and the image resolution if available. Otherwise it is equal to width scaling factor
      Gibt zurück:
      The value of the property 'width scaling factor'. I.e. 0.1 means 10%, 5.0 means 500%.

    • getHeightRenderingFactor

      public double getHeightRenderingFactor()
      Gets the property 'height rendering factor'. While 'height scaling factor' is a user defined factor, this rendering factor includes the user factor and the image resolution if available. Otherwise it is equal to height scaling factor.
      Gibt zurück:
      The value of the property 'height scaling factor'. I.e. 0.1 means 10%, 5.0 means 500%.

    • parseElement

      public NodeParser parseElement(com.inet.report.parser.XMLTag group, String tag, Attributes atts, Map<String,Object> parserMap) throws FatalParserException
      FOR INTERNAL USE ONLY FOR INTERNAL USE ONLY Internal method for reading report XML

      Parses an XML node with the given information, and returns either a sub-element which was created as a result, or null if no sub-element was created, i.e. the information was applied to the ReportComponent itself. Note that the parsing is highly tolerant, i.e. exceptions are intercepted and suppressed if at all possible.

      parseElement in Klasse Element
      Parameter:
      group - XMLTag of the current node to be parsed, or null if there is no such current group. An XMLTag is a group of nodes bundled together, usually it is a Properties node such as CommonProperties, BorderProperties, etc.
      tag - The XMLTag to be parsed
      atts - The set of attributes in the current XMLTag
      parserMap - The map of current Parser.
      Gibt zurück:
      The NodeParser sub-element if one needed to be created, or null if none was created.
      Löst aus:
      FatalParserException - if an exception occurs which causes the report to not be able to be read: causes the abortion of the reading of the report.

    • createPictureMetaData

      public com.inet.report.encode.PictureMetaData createPictureMetaData()
      Creates a meta data instance for this picture.
      Gibt zurück:
      the created meta data instance or null if no meta data can be retrieved (e.g. when picture data is missing or the data format is unknown)

    • getSubComponents

      public List<? extends ReportComponent> getSubComponents()
      Returns all ReportComponents that are descendants of this one. E.G. this will return all Element of a Section. But it's as well useful for CrossTabs or Text elements which have additional elements.
      Angegeben von:
      getSubComponents in Klasse ReportComponent
      Gibt zurück:
      a list with all sub components which can be empty as well; will be null if the component has no descendants
