TImageEnView.SelectMagicWand

Declaration

procedure SelectMagicWand(x, y: Integer; Op: TIESelOp);

Description

Selects an irregular region that has similar colors.

It uses the following properties:
◼MagicWandMode
◼MagicWandSize
◼MagicWandTolerance
◼MagicWandMaxFilter

Parameter	Description
x	Starting horizontal coordinate
y	Starting vertical coordinate
Op	If Op is iespReplace the region replaces the existing selection, otherwise if Op is iespAdd, the region is appended to the existing selection

Note:
◼If SelectionBase = iesbClientArea then x and y are assumed to be visible points on the control. If iesbBitmap, the points specify a position on the bitmap.
◼This is the programmatic equivalent of setting miSelectMagicWand in MouseInteractGeneral
◼MagicWandMode determines the nature of the magic wand selection. For iewInclusive a "vectorized" selection is created (i.e. the selection will be made up of a series of lines and can be accessed via PolySel). For other types a "bitmap" selection is used (to determine whether specific pixels are selected, use IsPointInsideSelection)

Example

ImageEnView1.SelectMagicWand(10, 10, iespReplace);
