TImageEnView.SelY2
Declaration
property SelY2: integer; (Read-only)
Description
Returns the bottom-right Y (row) coordinate of the selected area.
The value is a coordinate of the Bitmap itself, i.e. it is independent of scrolling (
ViewX and
ViewY) and
Zoom (e.g. you will get the same result whether the zoom is 50% or 100%).
Note:
◼You can convert the returned value to a screen value using
YBmp2Scr◼The selected area can be specified using
Select◼SelX2 and SelY2 are inclusive values, unlike
Select. Consider the following:
ImageEnView1.SelectionBase := iesbBitmap;
ImageEnView1.Select( 100, 100, 200, 200 );
Caption := format(' %d,%d,%d,%d', [ ImageEnView1.SelX1, ImageEnView1.SelY1, ImageEnView1.SelX2, ImageEnView1.SelY2 ]);
// Caption will be: 100,100,199,199// Enlarge the selection by ten pixels on all sides
With ImageEnView1 do
begin
SelectionBase := iesbBitmap;
Select( SelX1 - 10, SelY1 - 10, SelX2 - 10, SelY2 - 10 );
End;
