ImageEn, unit iexLayers




property LabelFillGradient: TIEGDIPlusGradient;


The direction of the gradient used for the text label fill.
If LabelFillColor is different from LabelFillColor2 the text box is filled with a gradient. LabelFillGradient specifies the direction.
To disable the gradient set the LabelFillColor2 to clNone, or LabelFillGradient to gpgNone.

Note: The label does not have a fill if LabelPosition is ielpAbove, ielpBelow, ielpAutoAbove or ielpAutoBelow

Default: gpgVertical


// Set a horizontal gradient fill for the label of a line layer
TIELineLayer(ImageEnView1.CurrentLayer).LabelFillColor := clRed;
TIELineLayer(ImageEnView1.CurrentLayer).LabelFillColor2 := clYellow;
TIELineLayer(ImageEnView1.CurrentLayer).LabelFillGradient := gpgHorizontal;
TIELineLayer(ImageEnView1.CurrentLayer).LabelBorderColor := clBlack;
TIELineLayer(ImageEnView1.CurrentLayer).LabelBorderWidth := 3;

// Which is the same as...
ImageEnView1.CurrentLayer.FillColor := clRed;
ImageEnView1.CurrentLayer.FillColor2 := clYellow;
ImageEnView1.CurrentLayer.FillGradient := gpgHorizontal;
ImageEnView1.CurrentLayer.BorderColor := clBlack;
ImageEnView1.CurrentLayer.BorderWidth := 3;

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
  lyr.FillGradient := TIELayerGradient( cmbGradient.ItemIndex - 1 );

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