TRSChartShadow Class

Create

Initializes a new instance of the TRSChartGraphic class. (Inherited from RSChartPanel.TRSChartGraphic.)

Brush

Represents property Brush.

Direction

Specifies the direction the shadow is drawn in. For example, if the Direction is sdBottomRight, the shadow will be drawn below and to the right as if the light source was above and to the left of the object.

OnChange

Occurs immediately after the chart graphic object changes. Write an OnChange event handler to take specific action when the chart graphic changes. The properties of the chart graphic reflect the new settings when OnChange occurs.

Opacity

Represents property Opacity.

Pen

Specifies the kind of pen the chart graphic area uses for drawing lines and outlining shapes. Set Pen to specify the pen to use for drawing lines and outlining shapes in the image.
 (Inherited from RSChartPanel.TRSChartGraphicArea.)

Size

Specifies the size in pixels of the shadow. When the   Direction is sdBottomRight, the shadow will be drawn Size pixels below and Size pixels to the right.

Style

Represents property Style.

Visible

Represents property Visible.

Assign(TPersistent)

Copies the contents of another similar object to the current object

Changed

Overloaded. Represents method Changed. (Inherited from RSChartPanel.TRSChartGraphic.)

Clone

Creates a "deep" copy of the chart graphic. It constructs a new chart graphic of the correct type and then calls the   Assign method to copy its properties to the new copy. (Inherited from RSChartPanel.TRSChartGraphic.)

Draw(TCanvas,TCanvasRect)

Overloaded. Paints the chart graphic to the specified Canvas in the specified location. It uses the current canvas' brush and pen. Use the Draw method to paint the chart graphic to any canvas and anywhere and with any size on the canvas.

Draw(TCanvas,TCanvasRect,TRSChartAxis,TRSChartAxis)

Overloaded.  Paints the chart graphic to the specified Canvas in the specified location. It uses the current canvas' brush and pen. Use the Draw method to paint the chart graphic to any canvas and anywhere and with any size on the canvas.

The VertAxis and HorizAxis parameters can be used to provide point to pixel conversions (see RSChartPanel.TRSChartAxis ).

Draw(TCanvas,TCanvasRect,TRSShapeStyle,Single)

Overloaded.  Paints the shadow on the canvas in the specified rectangle. It first calls  ShadowRect to figure out the rectangle that contains the shadow. Then, using the     Brush and Pen properties, it paints the shadow. The AStyle parameter defines the shape of the shadow.

The following graphic shows the interrelationships of the elements of the TRSChartShadow class:

Drawing(TCanvas,TCanvasRect)

Represents method Drawing(TCanvas,TCanvasRect). (Overrides RSChartPanel.TRSChartGraphic.Drawing(TCanvas,TCanvasRect).)

Drawn(TCanvas,TCanvasRect)

Represents method Drawn(TCanvas,TCanvasRect). (Inherited from RSChartPanel.TRSChartGraphic.)

Initialize

Represents method Initialize. (Overrides RSChartPanel.TRSChartGraphicArea.Initialize.)

InitializeEvents

Represents method InitializeEvents. (Overrides RSChartPanel.TRSChartGraphic.InitializeEvents.)

InternalDraw(TCanvas,TCanvasRect)

Overloaded. Represents method InternalDraw(TCanvas,TCanvasRect). (Overrides RSChartPanel.TRSChartGraphicArea.InternalDraw(TCanvas,TCanvasRect).)

NonShadowRect(TCanvasRect,Boolean,TCanvas)

Returns the rectangle of the object which is casting the shadow, given the ARect parameter. The method uses the     Size and     Direction to calculate a smaller rectangle within the ARect rectangle, which is in the opposite direction of the  ShadowRect.

SenderChanged(TObject)

Overloaded. Represents method SenderChanged(TObject). (Inherited from RSChartPanel.TRSChartGraphic.)

ShadowRect(TCanvasRect,Boolean,TCanvas)

Returns the rectangle of the shadow given the ARect parameter. The method uses the Size and Direction to calculate a shadow under the aRect. If the Constrained parameter is true, the shadow will be a subrectangle of the input rectangle.

TiledDraw(TCanvas,TCanvasRect,TTileGraphic,TCanvasPixel,TCanvasPixel)

Overloaded.  Tiles the image across the entire input rectangle.

The Image is drawn at full size from the top left of the ARect across and down until outside of the input rectangle. Use the overloaded TiledDraw methods to constrain the size of the Image.

TiledDraw(TCanvas,TCanvasRect,TTileGraphic,TCanvasPixel,TCanvasPixel,TCanvasPixel,TCanvasPixel)

Overloaded.  Tiles the image across the entire input rectangle.

The Image is drawn at ImageWidth, ImageHeight size from the top left of the ARect across and down until outside of the input rectangle.

TiledDraw(TCanvas,TCanvasRect,TTileGraphic,TCanvasRect)

Overloaded.  Tiles the image across the entire input rectangle.

The Image is drawn at ImageRect size from the top left of the ARect across and down until outside of the input rectangle.

VisibleChanged

Represents method VisibleChanged. (Overrides RSChartPanel.TRSChartGraphic.VisibleChanged.)

OnDraw

Occurs just after the chart graphic is painted. Write an OnDraw event handler to take specific action when the chart graphic has finished painting. The OnDraw event also allows you to do custom painting after the chart graphic has painted. (Inherited from RSChartPanel.TRSChartGraphic.)

OnDrawing

Occurs just before the chart graphic is painted. Write an OnDrawing event handler to take specific action when the chart graphic is about to paint. If the event handler sets the DoDraw parameter to False, the chart graphic will not be painted. The OnDraw event also allows you to do custom painting before the chart graphic has been painted. (Inherited from RSChartPanel.TRSChartGraphic.)
