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

Since:

3.0

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%.

createPictureMetaData

public com.inet.report.encode.PictureMetaData createPictureMetaData()

Creates a meta data instance for this picture.

Returns:

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 java.util.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.

Specified by:

getSubComponents in class ReportComponent

Returns:

a list with all sub components which can be empty as well; will be null if the component has no descendants
