Graphics  - AS3

Fills a drawing area with a bitmap image. The bitmap can be repeated or tiled to fill the area. The fill remains in effect until you call the beginFill(), beginBitmapFill(), beginGradientFill(), or beginShaderFill() method. Calling the clear() method clears the fill.

The application renders the fill whenever three or more points are drawn, or when the endFill() method is called.

Parameters

     matrix = new flash.geom.Matrix(); 
     matrix.rotate(Math.PI / 4);

Parameters

Related API Elements

Specifies a gradient fill used by subsequent calls to other Graphics methods (such as lineTo() or drawCircle()) for the object. The fill remains in effect until you call the beginFill(), beginBitmapFill(), beginGradientFill(), or beginShaderFill() method. Calling the clear() method clears the fill.

The application renders the fill whenever three or more points are drawn, or when the endFill() method is called.

Parameters

	type:String — A value from the GradientType class that specifies which gradient type to use: GradientType.LINEAR or GradientType.RADIAL.
	colors:Array — An array of RGB hexadecimal color values used in the gradient; for example, red is 0xFF0000, blue is 0x0000FF, and so on. You can specify up to 15 colors. For each color, specify a corresponding value in the alphas and ratios parameters.
	alphas:Array — An array of alpha values for the corresponding colors in the colors array; valid values are 0 to 1. If the value is less than 0, the default is 0. If the value is greater than 1, the default is 1.
	ratios:Array — An array of color distribution ratios; valid values are 0-255. This value defines the percentage of the width where the color is sampled at 100%. The value 0 represents the left position in the gradient box, and 255 represents the right position in the gradient box. Note: This value represents positions in the gradient box, not the coordinate space of the final gradient, which can be wider or thinner than the gradient box. Specify a value for each value in the colors parameter. For example, for a linear gradient that includes two colors, blue and green, the following example illustrates the placement of the colors in the gradient based on different values in the ratios array: ratios Gradient [0, 127] [0, 255] [127, 255] The values in the array must increase sequentially; for example, [0, 63, 127, 190, 255].
	matrix:Matrix (default = null) — A transformation matrix as defined by the flash.geom.Matrix class. The flash.geom.Matrix class includes a createGradientBox() method, which lets you conveniently set up the matrix for use with the beginGradientFill() method.
	spreadMethod:String (default = "pad") — A value from the SpreadMethod class that specifies which spread method to use, either: SpreadMethod.PAD, SpreadMethod.REFLECT, or SpreadMethod.REPEAT. For example, consider a simple linear gradient between two colors: import flash.geom.* import flash.display.* var fillType:String = GradientType.LINEAR; var colors:Array = [0xFF0000, 0x0000FF]; var alphas:Array = [1, 1]; var ratios:Array = [0x00, 0xFF]; var matr:Matrix = new Matrix(); matr.createGradientBox(20, 20, 0, 0, 0); var spreadMethod:String = SpreadMethod.PAD; this.graphics.beginGradientFill(fillType, colors, alphas, ratios, matr, spreadMethod); this.graphics.drawRect(0,0,100,100); This example uses SpreadMethod.PAD for the spread method, and the gradient fill looks like the following: If you use SpreadMethod.REFLECT for the spread method, the gradient fill looks like the following: If you use SpreadMethod.REPEAT for the spread method, the gradient fill looks like the following:
	interpolationMethod:String (default = "rgb") — A value from the InterpolationMethod class that specifies which value to use: InterpolationMethod.LINEAR_RGB or InterpolationMethod.RGB For example, consider a simple linear gradient between two colors (with the spreadMethod parameter set to SpreadMethod.REFLECT). The different interpolation methods affect the appearance as follows: InterpolationMethod.LINEAR_RGB InterpolationMethod.RGB
	focalPointRatio:Number (default = 0) — A number that controls the location of the focal point of the gradient. 0 means that the focal point is in the center. 1 means that the focal point is at one border of the gradient circle. -1 means that the focal point is at the other border of the gradient circle. A value less than -1 or greater than 1 is rounded to -1 or 1. For example, the following example shows a focalPointRatio set to 0.75:

Specifies a shader fill used by subsequent calls to other Graphics methods (such as lineTo() or drawCircle()) for the object. The fill remains in effect until you call the beginFill(), beginBitmapFill(), beginGradientFill(), or beginShaderFill() method. Calling the clear() method clears the fill.

The application renders the fill whenever three or more points are drawn, or when the endFill() method is called.

Shader fills are not supported under GPU rendering; filled areas will be colored cyan.

Clears the graphics that were drawn to this Graphics object, and resets fill and line style settings.

Copies all of drawing commands from the source Graphics object into the calling Graphics object.

Parameters

Draws a cubic Bezier curve from the current drawing position to the specified anchor point. Cubic Bezier curves consist of two anchor points and two control points. The curve interpolates the two anchor points and curves toward the two control points.

The four points you use to draw a cubic Bezier curve with the cubicCurveTo() method are as follows:

• The current drawing position is the first anchor point.
• The anchorX and anchorY parameters specify the second anchor point.
• The controlX1 and controlY1 parameters specify the first control point.
• The controlX2 and controlY2 parameters specify the second control point.

If you call the cubicCurveTo() method before calling the moveTo() method, your curve starts at position (0, 0).

If the cubicCurveTo() method succeeds, the Flash runtime sets the current drawing position to (anchorX, anchorY). If the cubicCurveTo() method fails, the current drawing position remains unchanged.

If your movie clip contains content created with the Flash drawing tools, the results of calls to the cubicCurveTo() method are drawn underneath that content.

Parameters

package {
    import flash.display.Sprite;
    import flash.display.Shape;
    
    public class Graphics_cubicCurveToExample extends Sprite
    {
        public function Graphics_cubicCurveToExample():void
        {
            var rounderObject:Shape = new Shape();

            rounderObject.graphics.beginFill(0x0000FF);
            rounderObject.graphics.moveTo(250, 0);
            rounderObject.graphics.cubicCurveTo(275, 0, 300, 25, 300, 50);
            rounderObject.graphics.cubicCurveTo(300, 75, 275, 100, 250, 100);
            rounderObject.graphics.cubicCurveTo(225, 100, 200, 75, 200, 50);
            rounderObject.graphics.cubicCurveTo(200, 25, 225, 0, 250, 0);
            rounderObject.graphics.endFill();
            
            this.addChild(rounderObject);
        }
    }
}

Draws a quadratic Bezier curve using the current line style from the current drawing position to (anchorX, anchorY) and using the control point that (controlX, controlY) specifies. The current drawing position is then set to (anchorX, anchorY). If the movie clip in which you are drawing contains content created with the Flash drawing tools, calls to the curveTo() method are drawn underneath this content. If you call the curveTo() method before any calls to the moveTo() method, the default of the current drawing position is (0, 0). If any of the parameters are missing, this method fails and the current drawing position is not changed.

The curve drawn is a quadratic Bezier curve. Quadratic Bezier curves consist of two anchor points and one control point. The curve interpolates the two anchor points and curves toward the control point.

Submits a series of IGraphicsData instances for drawing. This method accepts a Vector containing objects including paths, fills, and strokes that implement the IGraphicsData interface. A Vector of IGraphicsData instances can refer to a part of a shape, or a complex fully defined set of data for rendering a complete shape.

Graphics paths can contain other graphics paths. If the graphicsData Vector includes a path, that path and all its sub-paths are rendered during this operation.

Submits a series of commands for drawing. The drawPath() method accepts a Vector of individual moveTo(), lineTo(), and curveTo() drawing commands, combining them into a single call. The drawPath() method parameters combine drawing commands with x- and y-coordinate value pairs and a drawing direction. The drawing commands are integers, represented as constants defined in the GraphicsPathCommand class. The x- and y-coordinate value pairs are Numbers in an array where each pair defines a coordinate location. The drawing direction is a value from the GraphicsPathWinding class.

Generally, drawings render faster with drawPath() than with a series of individual lineTo() and curveTo() method calls.

The drawPath() method uses a uses a floating computation so rotation and scaling of shapes is more accurate and gives better results. However, curves submitted using the drawPath() method can have small sub-pixel alignment errors when used in conjunction with the lineTo() and curveTo() methods.

The drawPath() method also uses slightly different rules for filling and drawing lines. They are:

• When a fill is applied to rendering a path:
  • A sub-path of less than 3 points is not rendered. (But note that the stroke rendering will still occur, consistent with the rules for strokes below.)
  • A sub-path that isn't closed (the end point is not equal to the begin point) is implicitly closed.
• When a stroke is applied to rendering a path:
  • The sub-paths can be composed of any number of points.
  • The sub-path is never implicitly closed.

Parameters

Related API Elements

Renders a set of triangles, typically to distort bitmaps and give them a three-dimensional appearance. The drawTriangles() method maps either the current fill, or a bitmap fill, to the triangle faces using a set of (u,v) coordinates.

Any type of fill can be used, but if the fill has a transform matrix that transform matrix is ignored.

A uvtData parameter improves texture mapping when a bitmap fill is used.

Parameters

More examples

Related API Elements

Applies a fill to the lines and curves that were added since the last call to the beginFill(), beginGradientFill(), or beginBitmapFill() method. Flash uses the fill that was specified in the previous call to the beginFill(), beginGradientFill(), or beginBitmapFill() method. If the current drawing position does not equal the previous position specified in a moveTo() method and a fill is defined, the path is closed with a line and then filled.

Related API Elements

Specifies a bitmap to use for the line stroke when drawing lines.

The bitmap line style is used for subsequent calls to Graphics methods such as the lineTo() method or the drawCircle() method. The line style remains in effect until you call the lineStyle() or lineGradientStyle() methods, or the lineBitmapStyle() method again with different parameters.

You can call the lineBitmapStyle() method in the middle of drawing a path to specify different styles for different line segments within a path.

Call the lineStyle() method before you call the lineBitmapStyle() method to enable a stroke, or else the value of the line style is undefined.

Calls to the clear() method set the line style back to undefined.

Parameters

Related API Elements

Specifies a gradient to use for the stroke when drawing lines.

The gradient line style is used for subsequent calls to Graphics methods such as the lineTo() methods or the drawCircle() method. The line style remains in effect until you call the lineStyle() or lineBitmapStyle() methods, or the lineGradientStyle() method again with different parameters.

You can call the lineGradientStyle() method in the middle of drawing a path to specify different styles for different line segments within a path.

Call the lineStyle() method before you call the lineGradientStyle() method to enable a stroke, or else the value of the line style is undefined.

Calls to the clear() method set the line style back to undefined.

Parameters

	type:String — A value from the GradientType class that specifies which gradient type to use, either GradientType.LINEAR or GradientType.RADIAL.
	colors:Array — An array of RGB hex color values to be used in the gradient (for example, red is 0xFF0000, blue is 0x0000FF, and so on).
	alphas:Array — An array of alpha values for the corresponding colors in the colors array; valid values are 0 to 1. If the value is less than 0, the default is 0. If the value is greater than 1, the default is 1.
	ratios:Array — An array of color distribution ratios; valid values are from 0 to 255. This value defines the percentage of the width where the color is sampled at 100%. The value 0 represents the left position in the gradient box, and 255 represents the right position in the gradient box. This value represents positions in the gradient box, not the coordinate space of the final gradient, which can be wider or thinner than the gradient box. Specify a value for each value in the colors parameter. For example, for a linear gradient that includes two colors, blue and green, the following figure illustrates the placement of the colors in the gradient based on different values in the ratios array: ratios Gradient [0, 127] [0, 255] [127, 255] The values in the array must increase, sequentially; for example, [0, 63, 127, 190, 255].
	matrix:Matrix (default = null) — A transformation matrix as defined by the flash.geom.Matrix class. The flash.geom.Matrix class includes a createGradientBox() method, which lets you conveniently set up the matrix for use with the lineGradientStyle() method.
	spreadMethod:String (default = "pad") — A value from the SpreadMethod class that specifies which spread method to use: SpreadMethod.PAD SpreadMethod.REFLECT SpreadMethod.REPEAT
	interpolationMethod:String (default = "rgb") — A value from the InterpolationMethod class that specifies which value to use. For example, consider a simple linear gradient between two colors (with the spreadMethod parameter set to SpreadMethod.REFLECT). The different interpolation methods affect the appearance as follows: InterpolationMethod.LINEAR_RGB InterpolationMethod.RGB
	focalPointRatio:Number (default = 0) — A number that controls the location of the focal point of the gradient. The value 0 means the focal point is in the center. The value 1 means the focal point is at one border of the gradient circle. The value -1 means that the focal point is at the other border of the gradient circle. Values less than -1 or greater than 1 are rounded to -1 or 1. The following image shows a gradient with a focalPointRatio of -0.75:

Specifies a shader to use for the line stroke when drawing lines.

The shader line style is used for subsequent calls to Graphics methods such as the lineTo() method or the drawCircle() method. The line style remains in effect until you call the lineStyle() or lineGradientStyle() methods, or the lineBitmapStyle() method again with different parameters.

You can call the lineShaderStyle() method in the middle of drawing a path to specify different styles for different line segments within a path.

Call the lineStyle() method before you call the lineShaderStyle() method to enable a stroke, or else the value of the line style is undefined.

Calls to the clear() method set the line style back to undefined.

Specifies a line style used for subsequent calls to Graphics methods such as the lineTo() method or the drawCircle() method. The line style remains in effect until you call the lineGradientStyle() method, the lineBitmapStyle() method, or the lineStyle() method with different parameters.

You can call the lineStyle() method in the middle of drawing a path to specify different styles for different line segments within the path.

Note: Calls to the clear() method set the line style back to undefined.

Note: Flash Lite 4 supports only the first three parameters (thickness, color, and alpha).

Parameters

Related API Elements

Draws a line using the current line style from the current drawing position to (x, y); the current drawing position is then set to (x, y). If the display object in which you are drawing contains content that was created with the Flash drawing tools, calls to the lineTo() method are drawn underneath the content. If you call lineTo() before any calls to the moveTo() method, the default position for the current drawing is (0, 0). If any of the parameters are missing, this method fails and the current drawing position is not changed.

Parameters

package {
    import flash.display.Sprite;
    import flash.display.LineScaleMode;
    import flash.display.CapsStyle;
    import flash.display.JointStyle;
    import flash.display.Shape;


    public class Graphics_lineToExample extends Sprite {

        public function Graphics_lineToExample() {

            var trapezoid:Shape = new Shape();    

            trapezoid.graphics.lineStyle(10, 0xFFD700, 1, false, LineScaleMode.VERTICAL,
                               CapsStyle.NONE, JointStyle.MITER, 10);

            trapezoid.graphics.moveTo(100, 100);
 
            trapezoid.graphics.lineTo(120, 50);
            trapezoid.graphics.lineTo(200, 50);
            trapezoid.graphics.lineTo(220, 100);
            trapezoid.graphics.lineTo(100, 100); 

            this.addChild(trapezoid);
        }
    }
}

Moves the current drawing position to (x, y). If any of the parameters are missing, this method fails and the current drawing position is not changed.

Parameters

    import flash.display.Sprite;
    import flash.display.CapsStyle;
    import flash.display.LineScaleMode;

    public class Graphics_moveToExample extends Sprite
    {
        public function Graphics_moveToExample() {
            
            graphics.lineStyle(3, 0x990000, 0.25, false, 
                            LineScaleMode.NONE, CapsStyle.SQUARE);

            graphics.moveTo(120, 20);
            graphics.lineTo(130, 20);           
        }
    }
}

Queries a Sprite or Shape object (and optionally, its children) for its vector graphics content. The result is a Vector of IGraphicsData objects. Transformations are applied to the display object before the query, so the returned paths are all in the same coordinate space. Coordinates in the result data set are relative to the stage, not the display object being sampled.

The result includes the following types of objects, with the specified limitations:

• GraphicsSolidFill
• GraphicsGradientFill
  • All properties of the gradient fill are returned by readGraphicsData().
  • The matrix returned is close to, but not exactly the same as, the input matrix.
• GraphicsEndFill
• GraphicsBitmapFill
  • The matrix returned is close to, but not exactly the same as, the input matrix.
  • repeat is always true.
  • smooth is always false.
• GraphicsStroke
  • thickness is supported.
  • fill supports GraphicsSolidFill, GraphicsGradientFill, and GraphicsBitmapFill as described previously
  • All other properties have default values.
• GraphicsPath
  • The only supported commands are MOVE_TO, CURVE_TO, and LINE_TO.

The following visual elements and transformations can't be represented and are not included in the result:

• Masks
• Text, with one exception: Static text that is defined with anti-alias type "anti-alias for animation" is rendered as vector shapes so it is included in the result.
• Shader fills
• Blend modes
• 9-slice scaling
• Triangles (created with the drawTriangles() method)
• Opaque background
• scrollrect settings
• 2.5D transformations
• Non-visible objects (objects whose visible property is false)

1. Declare a size property for later use in determining the size of each shape.
2. Declare properties that set the background color to orange, the border color to dark gray, the border size to 0 pixels, the corner radius to 9 pixels, and set the space between the stage edge and the other objects to be 5 pixels.
3. Use the properties declared in the preceding steps along with the built in methods of the Graphics class to draw the circle, rounded rectangle, and square at coordinates x = 0, y = 0.
4. Redraw each of the shapes along the top of the stage, starting at x = 5, y = 5, with a 5-pixel spacing between shapes.
