Class: Graphics

PIXI. Graphics

new 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.

Extends

Members

alphanumber

The opacity of the object.

blendModenumber

The blend mode to be applied to the graphic shape. Apply a value of PIXI.BLEND_MODES.NORMAL to reset the blend mode.

Default Value:
  • PIXI.BLEND_MODES.NORMAL;
See:

boundsPaddingnumber

The bounds' padding used for bounds calculation.

cacheAsBitmapboolean

Set this to true if you want this display object to be cached as a bitmap.
This basically takes a snap shot of the display object as it is at that moment. It can provide a performance benefit for complex static displayObjects.
To remove simply set this property to 'false'

readonlychildrenArray.<PIXI.DisplayObject>

The array of children of this container.

fillAlphanumber

The alpha value used when filling the Graphics object.

Default Value:
  • 1

filterAreaPIXI.Rectangle

The area the filter is applied to. This is used as more of an optimisation
rather than figuring out the dimensions of the displayObject each frame you can set this rectangle

filtersArray.<PIXI.AbstractFilter>

Sets the filters for the displayObject.

  • IMPORTANT: This is a webGL only feature and will be ignored by the canvas renderer.
    To remove filters simply set this property to 'null'

heightnumber

The height of the Container, setting this will actually modify the scale to achieve the value set

isMaskboolean

Whether this shape is being used as a mask.

lineColorstring

The color of any lines drawn.

Default Value:
  • 0

lineWidthnumber

The width (thickness) of any lines drawn.

Default Value:
  • 0

Sets a mask for the displayObject. A mask is an object that limits the visibility of an object to the shape of the mask applied to it.
In PIXI a regular mask must be a PIXI.Graphics or a PIXI.Sprite object. This allows for much faster masking in canvas as it utilises shape clipping.
To remove a mask, set this property to null.

TODO
  • For the moment, PIXI.CanvasRenderer doesn't support PIXI.Sprite as mask.

readonlyparentPIXI.Container

The display object container that contains this display object.

pivotPIXI.Point

The pivot point of the displayObject that it rotates around

positionPIXI.Point

The coordinate of the object relative to the local coordinates of the parent.

renderableboolean

Can this object be rendered, if false the object will not be drawn but the updateTransform
methods will still be called.

rotationnumber

The rotation of the object in radians.

scalePIXI.Point

The scale factor of the object.

The skew factor for the object in radians.

tintnumber

The tint applied to the graphic shape. This is a hex value. Apply a value of 0xFFFFFF to reset the tint.

Default Value:
  • 0xFFFFFF

visibleboolean

The visibility of the object. If false the object will not be drawn, and
the updateTransform function will not be called.

widthnumber

The width of the Container, setting this will actually modify the scale to achieve the value set

readonlyworldAlphanumber

The multiplied alpha of the displayObject

readonlyworldTransformPIXI.Matrix

Current transform of the object based on world (parent) factors

readonlyworldVisibleboolean

Indicates if the sprite is globally visible.

xnumber

The position of the displayObject on the x axis relative to the local coordinates of the parent.

ynumber

The position of the displayObject on the y axis relative to the local coordinates of the parent.
