Subject: Re: Question about the CopySelectionToClipBoard
In reply to: Jean-Michel Gaudette 's message, "Question about the CopySelectionToClipBoard" on 08:26:17 02/18/02 Mon

Bonjour Jean-Michel,

Here is a new implementation that uses the original graphic, not the displayed graphic.

Best regards,


procedure TRubberbandMouseHandler.CopySelectionToClipBoard;
Rect : TRect;
Graphic : TDibGraphic;
CropTransform : TCropTransform;
DisplayedGraphic : TDibGraphic;
SourceWidth : Integer;
SourceHeight : Integer;
if not SelectionActive then
raise ERubberbandError.Create(msgRegionNotSelected);

DisplayedGraphic := TDibGraphic(FImageScrollBox.FImage.Picture.Graphic);

SourceWidth := FImageScrollBox.FSourceGraphic.Width;
SourceHeight := FImageScrollBox.FSourceGraphic.Height;

Rect.Top := FY1 * SourceHeight div DisplayedGraphic.Height;
Rect.Bottom := FY2 * SourceHeight div DisplayedGraphic.Height;
Rect.Left := FX1 * SourceWidth div DisplayedGraphic.Width;
Rect.Right := FX2 * SourceWidth div DisplayedGraphic.Width;


if ((Rect.Right - Rect.Left) >= 1) and
((Rect.Bottom - Rect.Top) >= 1) then
Graphic := TDibGraphic.Create;
CropTransform := TCropTransform.Create;
CropTransform.Top := Rect.Top;
CropTransform.Left := Rect.Left;
CropTransform.Bottom := SourceHeight - Rect.Bottom;
CropTransform.Right := SourceWidth - Rect.Right;

CropTransform.ApplyOnDest( FImageScrollBox.FSourceGraphic, Graphic);
