final class GraphicsBitmapFill
package openfl.display
implements IGraphicsFill, IGraphicsData
Available on all platforms
Defines a bitmap fill. The bitmap can be smoothed, repeated or tiled to
fill the area; or manipulated using a transformation matrix.
Use a GraphicsBitmapFill object with the Graphics.drawGraphicsData()
method. Drawing a GraphicsBitmapFill object is the equivalent of calling
the Graphics.beginBitmapFill() method.
Constructor
new(?bitmapData:BitmapData, ?matrix:Matrix, repeat:Bool = true, smooth:Bool = false)
Creates a new GraphicsBitmapFill object.
Parameters:
bitmapData | A transparent or opaque bitmap image that contains the bits to display. |
|---|---|
matrix | A matrix object (of the openfl.geom.Matrix class), which you use to define transformations on the bitmap. |
repeat | If |
smooth | If |
Variables
matrix:Matrix
A matrix object (of the openfl.geom.Matrix class) that defines transformations on the bitmap. For example, the following matrix rotates a bitmap by 45 degrees (pi/4 radians):
var matrix = new openfl.geom.Matrix();
matrix.rotate(Math.PI / 4);repeat:Bool
Specifies whether to repeat the bitmap image in a tiled pattern.
If true, the bitmap image repeats in a tiled pattern. If false,
the bitmap image does not repeat, and the outermost pixels along the
edges of the bitmap are used for any fill area that extends beyond the
bounds of the bitmap.
For example, consider the following bitmap (a 20 x 20-pixel checkerboard pattern):
When repeat is set to true (as in the following example), the
bitmap fill repeats the bitmap:
When repeat is set to false, the bitmap fill uses the edge pixels
for the fill area outside the bitmap:
smooth:Bool
Specifies whether to apply a smoothing algorithm to the bitmap image.
If false, upscaled bitmap images are rendered by using a
nearest-neighbor algorithm and look pixelated. If true, upscaled
bitmap images are rendered by using a bilinear algorithm. Rendering by
using the nearest neighbor algorithm is usually faster.
