TIELineLayer.LabelFillGradient

Declaration

property LabelFillGradient: TIEGDIPlusGradient;

Description

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

Example

// 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;
ImageEnView1.Update();

// 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;
ImageEnView1.Update();

Compatibility Notes

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 );
