ImageReplacedElement

protected ImageReplacedElement()

ImageReplacedElement

public ImageReplacedElement(Image image,
 int targetWidth,
 int targetHeight)

Creates a new ImageReplacedElement and scales it to the size specified if either width or height has a valid value (values are greater than -1), otherwise original size is preserved. The idea is that the image was loaded at a certain size (that's the Image instance here) and that at the time we create the ImageReplacedElement we have a target W/H we want to use.

Parameters:

image - An image.

targetWidth - The width we'd like the image to have, in pixels.

targetHeight - The height we'd like the image to have, in pixels.
