PIXI. Graphics

The Graphics class contains methods used to draw primitive shapes such as lines, circles and
rectangles to the display, and to color and fill them.

Members

cacheAsBitmapboolean

When cacheAsBitmap is set to true the graphics object will be rendered as if it was a sprite.
This is useful if your graphics element does not change often, as it will speed up the rendering
of the object in exchange for taking up texture memory. It is also useful if you need the graphics
object to be anti-aliased, because it will be rendered using canvas. This is not recommended if
you are constantly redrawing the graphics element.

Default Value:
  • false

filters

Shallow copies the array to the filters of the object.

height

Sets the height of the container by modifying the scale.

mask

Sets the mask.

pivot

Copies the point to the pivot of the object.

position

Copies the point to the position of the object.

rotation

Sets the rotation of the object.

scale

Copies the point to the scale of the object.

skew

Copies the point to the skew of the object.

width

Sets the width of the container by modifying the scale.

x

Sets the X position of the object.

y

Sets the Y position of the object.
