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:
// 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();
// Add a "Shape" layer with margins around text
ImageEnView1.LayersAdd( ielkText );
TIETextLayer( ImageEnView1.CurrentLayer ).Text := 'EXPLOSION!';
TIETextLayer( ImageEnView1.CurrentLayer ).Font.Style := [fsBold];
TIETextLayer( ImageEnView1.CurrentLayer ).Alignment := iejCenter;
TIETextLayer( ImageEnView1.CurrentLayer ).Layout := ielCenter;
TIETextLayer( ImageEnView1.CurrentLayer ).HorzMargin := 0.15;
TIETextLayer( ImageEnView1.CurrentLayer ).VertMargin := 0.25;
ImageEnView1.CurrentLayer.BorderColor := clBlack;
ImageEnView1.CurrentLayer.BorderWidth := 1;
ImageEnView1.CurrentLayer.FillColor := clRed;
ImageEnView1.CurrentLayer.FillColor2 := clYellow;
ImageEnView1.CurrentLayer.FillGradient := gpgVertCenter;
TIETextLayer( ImageEnView1.CurrentLayer ).SizeToText();
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 and older
if cmbGradient.ItemIndex = 0 then
lyr.FillGradient := gpgNone
else
lyr.FillGradient := TIELayerGradient( cmbGradient.ItemIndex - 1 );
// v10.0.0 and newer
lyr.FillGradient := TIEGDIPlusGradient( cmbGradient.ItemIndex );
