TIELayer.FillGradient

TIELayer.FillGradient


Declaration

property FillGradient: TIEGDIPlusGradient;


Description

Provides generic access to the gradient fill direction for the layer.
To disable the gradient set the FillColor2 to clNone, or FillGradient to gpgNone.

FillGradient accesses the following properties:
Class Property
TIEImageLayer N/A
TIEShapeLayer FillGradient
TIELineLayer LabelFillGradient
TIEPolylineLayer FillGradient
TIEAngleLayer -
TIETextLayer FillGradient




Example

// Set a vertical gradient fill for an ellipse
ImageEnView1.CurrentLayer.FillColor2 := clRed;
ImageEnView1.CurrentLayer.FillColor := clYellow;
ImageEnView1.CurrentLayer.FillGradient := gpgVertical;
ImageEnView1.CurrentLayer.BorderWidth := 0;
ImageEnView1.Update();



// Set a horizontal gradient fill for the label of a line layer
ImageEnView1.CurrentLayer.FillColor := clRed;
ImageEnView1.CurrentLayer.FillColor2 := clYellow;
ImageEnView1.CurrentLayer.FillGradient := gpgHorizontal;
ImageEnView1.CurrentLayer.BorderColor := clBlack;
ImageEnView1.CurrentLayer.BorderWidth := 3;
ImageEnView1.Update();





Compatibility Information

Prior to v10.0.0, Layer Gradients were of type TIELayerGradient. All gradients are now type TIEGDIPlusGradient.
Conversions are as follows: grdNone -> gpgNone, grdHorizontal -> gpgHorizontal, grdVertical -> gpgVertical, grdHorzCenter -> gpgHorzCenter, grdVertCenter -> gpgVertCenter, grdDiagonal -> gpgDiagonal, grdDiagonal2 -> gpgDiagonal2, grdDiagCentered -> gpgDiagCenter, grdDiagCentered2 -> gpgDiagCenter2
Note: Items of TIEGDIPlusGradient do not have the same indexes as TIELayerGradient.

// cmbGradient contains items: None, Horizontal, Vertical, Horz Center...

// <= v9.3.1
if cmbGradient.ItemIndex = 0 then
  lyr.FillGradient := gpgNone
else
  lyr.FillGradient := TIELayerGradient( cmbGradient.ItemIndex - 1 );

// v10.0.0
lyr.FillGradient := TIEGDIPlusGradient( cmbGradient.ItemIndex );
