Constructor Details

Image

public Image()

Creates an image with no drawable, stretched, and aligned center.

Image

public Image(@Null
 NinePatch patch)

Creates an image stretched, and aligned center.

Parameters:

patch - May be null.

Image

public Image(@Null
 TextureRegion region)

Creates an image stretched, and aligned center.

Parameters:

region - May be null.

Image

public Image(Texture texture)

Creates an image stretched, and aligned center.

Image

public Image(@Null
 Drawable drawable)

Creates an image stretched, and aligned center.

Parameters:

drawable - May be null.

Image

public Image(@Null
 Drawable drawable,
 Scaling scaling)

Creates an image aligned center.

Parameters:

drawable - May be null.

Image

public Image(@Null
 Drawable drawable,
 Scaling scaling,
 int align)

Parameters:

drawable - May be null.

Method Details

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() on 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(Batch 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 - The parent alpha, to be multiplied with this actor's alpha, allowing the parent's alpha to affect all children.

setDrawable

public void setDrawable(@Null
 Drawable drawable)

Sets a new drawable for the image. The image's pref size is the drawable's min size. If using the image actor's size rather than the pref size, Widget.pack() can be used to size the image to its pref size.

Parameters:

drawable - May be null.

getDrawable

@Null
public Drawable getDrawable()

Returns:

May be null.

setScaling

public void setScaling(Scaling scaling)

setAlign

public void setAlign(int align)

getAlign

public int getAlign()

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()

toString

public String toString()

Overrides:

toString in class Actor
