public class Image
extends Widget

Displays a Drawable, scaled various way within the widgets bounds. The preferred size is the min size of the drawable. Only when using a TextureRegionDrawable will the actor's scale, rotation, and origin be used when drawing.

Method Detail

layout

public void layout()

Description copied from interface: Layout

Computes and caches any information needed for drawing and, if this actor has children, positions and sizes each child, calls Layout.invalidate() any each child whose width or height has changed, and calls Layout.validate() on each child. This method should almost never be called directly, instead Layout.validate() should be used.

Specified by:

layout in interface Layout

Overrides:

layout in class Widget

draw

public void draw(SpriteBatch batch,
                 float parentAlpha)

Description copied from class: Widget

If this method is overridden, the super method or Widget.validate() should be called to ensure the widget is laid out.

Overrides:

draw in class Widget

parentAlpha - Should be multiplied with the actor's alpha, allowing a parent's alpha to affect all children.

setDrawable

public void setDrawable(Skin skin,
                        String drawableName)

setDrawable

public void setDrawable(Drawable drawable)

getDrawable

public Drawable getDrawable()

setScaling

public void setScaling(Scaling scaling)

setAlign

public void setAlign(int align)

getMinWidth

public float getMinWidth()

Specified by:

getMinWidth in interface Layout

Overrides:

getMinWidth in class Widget

getMinHeight

public float getMinHeight()

Specified by:

getMinHeight in interface Layout

Overrides:

getMinHeight in class Widget

getPrefWidth

public float getPrefWidth()

Specified by:

getPrefWidth in interface Layout

Overrides:

getPrefWidth in class Widget

getPrefHeight

public float getPrefHeight()

Specified by:

getPrefHeight in interface Layout

Overrides:

getPrefHeight in class Widget

getImageX

public float getImageX()

getImageY

public float getImageY()

getImageWidth

public float getImageWidth()

getImageHeight

public float getImageHeight()
