Method Detail

getImage

public java.awt.Image getImage(byte[] data,
                               boolean errorImage)

convert the given data to an image

Parameters:

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

Returns:

the resulting image or null / an error image if some problem is encountered

getImageStatic

public static java.awt.Image getImageStatic(byte[] data,
                                            boolean errorImage)

convert the given data to an image

Parameters:

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

Returns:

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

Returns:

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.

Returns:

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,
                               java.lang.String tag,
                               org.xml.sax.Attributes atts,
                               java.util.Map 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.

Specified by:

parseElement in interface NodeParser

Parameters:

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.

Returns:

The NodeParser sub-element if one needed to be created, or null if none was created.

Throws:

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.
