Hello
I am experiencing the following problem using ImageEn V4.0.2:
- grid displaying is enabled in the ImageEnView component located on a form
- the grid is correctly displayed on the main Layer 0
- I create a new Layer 1
- after that the grid is no more displayed on the main Layer 0, but only on the newly created Layer 1.
This can be easily reproduced by the code below:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ieview, imageenview, imageen;
type
TForm1 = class(TForm)
ImageEn1: TImageEn;
Button1: TButton; // Button to be pressed to create a new layer
procedure Init(Sender: TObject); // called by Form1.OnShow event
procedure AddLayerClick(Sender: TObject); // called by Button1.OnClick event
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
// called by Form1.OnShow event in order to initialize ImageEn1
procedure TForm1.Init(Sender: TObject);
begin
with ImageEn1 do
begin
Zoom:=400; // set zoom factor=400% in order to allow displaying the grid
DisplayGrid:=true; // display the grid on main Layer[0]
end;
end;
// called by the Button1.OnClick event
// Button1 is pressed on Form1 and a new layer is created
// the grid is NO more displayed on main Layer[0] of ImageEn1,
// but only on the newly created Layer[1]
procedure TForm1.AddLayerClick(Sender: TObject);
begin
with ImageEn1 do
begin
// select an area
Select(20,20,120,120);
// create a new layer from the selection
LayersCreateFromSelection;
end;
Button1.Enabled:=false; // don't allow new layers to be created
end;
end.
I need the grid to remain displayed on the main Layer 0,
as it would be normal.
Thank you in advance for a solution.

Hello,
current release shows the grid on current layer (or on the entire layer 0 when layer 0 is selected).
Since next minor release this behavior can be changed allowing following possibilities:
- display the grid on current layer (current and default behavior)
- display the grid on a specific layer (or 0 if you want to cover the entire layer 0 area)
The new property will be:
ImageEnView1.DisplayGridLyr := 0; // draw grid on layer 0 |

Can you please tell me when the next minor release will be available?
I need to deliver the application to the customer ASAP. |
