public class ComponentImage.EncodedWrapper
extends EncodedImage

A wrapper for ComponentImage to convert it to an EncodedImage.

Method Summary

Modifier and Type	Method	Description
protected Image	getInternal()	Returns the actual image represented by the encoded image, this image will be cached in a weak/soft reference internally.
Image	scaled(int width, int height)	Returns a scaled version of this image image using the given width and height, this is a fast algorithm that preserves translucent information.
EncodedImage	scaledEncoded(int width, int height)	Performs scaling using ImageIO to generate an encoded Image

Method Details

scaledEncoded

public EncodedImage scaledEncoded(int width,
 int height)

Performs scaling using ImageIO to generate an encoded Image

Parameters

• width: the width of the image, -1 to scale based on height and preserve aspect ratio

• height: the height of the image, -1 to scale based on width and preserve aspect ratio

Returns

new encoded image

Overrides:

scaledEncoded in class EncodedImage

scaled

public Image scaled(int width,
 int height)

Returns a scaled version of this image image using the given width and height, this is a fast algorithm that preserves translucent information. The method accepts -1 to preserve aspect ratio in the given axis.

Parameters

• width: width for the scaling

• height: height of the scaled image

Returns

new image instance scaled to the given height and width

Overrides:

scaled in class EncodedImage

getInternal

protected Image getInternal()

Returns the actual image represented by the encoded image, this image will be cached in a weak/soft reference internally. This method is useful to detect when the system actually created an image instance. You shouldn't invoke this method manually!

Returns

drawable image instance

Overrides:

getInternal in class EncodedImage
