JRFillImage

protected JRFillImage(JRBaseFiller filler,
                      JRImage image,
                      JRFillObjectFactory factory)

Method Detail

getModeValue

public ModeEnum getModeValue()

Description copied from interface: JRCommonElement

Returns the element transparency mode. The default value depends on the type of the report element. Graphic elements like rectangles and lines are opaque by default, but the images are transparent. Both static texts and text fields are transparent by default, and so are the subreport elements.

Specified by:

getModeValue in interface JRCommonElement

Overrides:

getModeValue in class JRFillElement

getScaleImageValue

public ScaleImageEnum getScaleImageValue()

Description copied from interface: JRCommonImage

Specified by:

getScaleImageValue in interface JRCommonImage

Returns:

a value representing one of the scale type constants in ScaleImageEnum

getOwnScaleImageValue

public ScaleImageEnum getOwnScaleImageValue()

Description copied from interface: JRCommonImage

Gets the image own scale type.

Specified by:

getOwnScaleImageValue in interface JRCommonImage

Returns:

a value representing one of the scale type constants in ScaleImageEnum

setScaleImage

public void setScaleImage(ScaleImageEnum scaleImage)

Description copied from interface: JRCommonImage

Sets the image scale type.

setVerticalAlignment

public void setVerticalAlignment(VerticalAlignEnum verticalAlignment)

Description copied from interface: JRAlignment

Gets the text vertical alignment.

Specified by:

setVerticalAlignment in interface JRAlignment

Parameters:

verticalAlignment - a value representing one of the vertical alignment constants in VerticalAlignEnum

isUsingCache

public boolean isUsingCache()

Deprecated. Replaced by getUsingCache().

Description copied from interface: JRImage

Indicates if the engine is loading the current image from cache. Implementations of this method rely on default values that depend on the type of the image expression if a value was not explicitly set of this flag.

Specified by:

isUsingCache in interface JRImage

Returns:

true if the image should be loaded from cache, false otherwise

isOwnUsingCache

public Boolean isOwnUsingCache()

Deprecated. Replaced by getUsingCache().

Specified by:

isOwnUsingCache in interface JRImage

getUsingCache

public Boolean getUsingCache()

Description copied from interface: JRImage

Indicates if the engine is loading the current image from cache. Implementations of this method return the actual value for the internal flag that was explicitly set on this image element.

Specified by:

getUsingCache in interface JRImage

Returns:

Boolean.TRUE if the image should be loaded from cache, Boolean.FALSE otherwise or null in case the flag was never explicitly set on this image element

setUsingCache

public void setUsingCache(boolean isUsingCache)

Description copied from interface: JRImage

Specifies if the engine should be loading the current image from cache. If set to true, the reporting engine will try to recognize previously loaded images using their specified source. For example, it will recognize an image if the image source is a file name that it has already loaded, or if it is the same URL.

For image elements that have expressions returning java.lang.String objects as the image source, representing file names, URLs or classpath resources, the default value for this flag is true.

Specified by:

setUsingCache in interface JRImage

setUsingCache

public void setUsingCache(Boolean isUsingCache)

Description copied from interface: JRImage

Specifies if the engine should be loading the current image from cache. If set to Boolean.TRUE, the reporting engine will try to recognize previously loaded images using their specified source. For example, it will recognize an image if the image source is a file name that it has already loaded, or if it is the same URL.

If set to null, the engine will rely on some default value which depends on the type of the image expression. The cache is turned on by default only for images that have java.lang.String objects in their expressions.

Specified by:

setUsingCache in interface JRImage

isLazy

public boolean isLazy()

Description copied from interface: JRImage

Indicates if the images will be loaded lazily or not.

Specified by:

setLazy in interface JRImage

Parameters:

isLazy - specifies whether
