Enum Constant Summary

Enum Constants

Enum Constant	Description
CLIP	A constant value specifying that if the actual image is larger than the image element size, it will be cut off so that it keeps its original resolution, and only the region that fits the specified size will be displayed.
FILL_FRAME	A constant value specifying that if the dimensions of the actual image do not fit those specified for the image element that displays it, the image can be forced to obey them and stretch itself so that it fits in the designated output area.
REAL_HEIGHT	A scale image type that instructs the engine to stretch the image height to fit the actual height of the image.
REAL_SIZE	A scale image type that stretches the images height in the same way as REAL_HEIGHT, and in addition it reduces the image width to the actual width of the image.
RETAIN_SHAPE	A constant value specifying that if the actual image does not fit into the image element, it can be adapted to those dimensions without needing to change its original proportions.

Method Summary

Modifier and Type	Method	Description
static ScaleImageEnum	getByName(String name)
String	getName()
static ScaleImageEnum	valueOf(String name)	Returns the enum constant of this type with the specified name.
static ScaleImageEnum[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

CLIP

public static final ScaleImageEnum CLIP

A constant value specifying that if the actual image is larger than the image element size, it will be cut off so that it keeps its original resolution, and only the region that fits the specified size will be displayed.

FILL_FRAME

public static final ScaleImageEnum FILL_FRAME

A constant value specifying that if the dimensions of the actual image do not fit those specified for the image element that displays it, the image can be forced to obey them and stretch itself so that it fits in the designated output area.

RETAIN_SHAPE

public static final ScaleImageEnum RETAIN_SHAPE

A constant value specifying that if the actual image does not fit into the image element, it can be adapted to those dimensions without needing to change its original proportions.

REAL_HEIGHT

public static final ScaleImageEnum REAL_HEIGHT

A scale image type that instructs the engine to stretch the image height to fit the actual height of the image.

Several restrictions apply to the image stretching mechanism:

• It only works when the image renderer implements DimensionRenderable.
• If the actual image width exceeds the declared image element width, the image is proportionally stretched to fit the declared width.
• Images with delayed evaluation (see JREvaluation.getEvaluationTime()) do not stretch and is proportionally shrunk to fit the declared height/width.
• An image overflows (to the next page/column) only once, after this the image gets rendered on the available space by proportionally shrinking its size.

REAL_SIZE

REAL_SIZE

public static final ScaleImageEnum REAL_SIZE

A scale image type that stretches the images height in the same way as REAL_HEIGHT, and in addition it reduces the image width to the actual width of the image. This can be useful when, for instance, a border has to be drawn around the image, respecting its actual size.

Method Detail

values

public static ScaleImageEnum[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ScaleImageEnum c : ScaleImageEnum.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ScaleImageEnum valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getName

public String getName()

Specified by:

getName in interface NamedEnum

getByName

public static ScaleImageEnum getByName(String name)
