xequte	Posted - Sep 18 2019 : 17:04:26 Yes, sorry. Please email me for an update. You can use the OnViewChange event as follows: procedure TMyForm.ImageEnMViewOnViewChange(Sender: TObject; Change: integer); begin // Restrict zoom to range of 50 - 200 if ( Change = 1 ) and ( Zoom < 50 ) then Zoom := 50 else if ( Change = 1 ) and ( Zoom > 200 ) then Zoom := 200; end; Nigel Xequte Software www.imageen.com
haya	Posted - Sep 18 2019 : 15:11:38 But OnZoomIn/OnZoomOut events available only in TImageEnView The question is about TImageEnMView
xequte	Posted - Sep 18 2019 : 03:24:14 Hi Use the OnZoomIn/OnZoomOut events, and change the NewZoom value if it is invalid. https://www.imageen.com/help/TImageEnView.OnZoomIn.html https://www.imageen.com/help/TImageEnView.OnZoomOut.html Nigel Xequte Software www.imageen.com
haya	Posted - Sep 17 2019 : 17:00:16 Thanks, I will do so. One more question: how to set maximum (and minimum) allowed zoom sizing?
xequte	Posted - Sep 16 2019 : 16:54:39 Hi MouseWheelParamsAlt was added in a recent version. What version of ImageEn do you have? You may want to extend at: https://www.imageen.com/order/ Nigel Xequte Software www.imageen.com
haya	Posted - Sep 16 2019 : 05:48:40 Thanks for answer! I trying to use this code: ImageEnMView1.MouseWheelParams.Action:= iemwVScroll; ImageEnMView1.MouseWheelParamsAlt.Action:= iemwZoomView; But got this error messages: [dcc32 Error] E2003 Undeclared identifier: 'iemwZoomView' [dcc32 Error] E2003 Undeclared identifier: 'MouseWheelParamsAlt' Which modules should I add in "uses" section?
xequte	Posted - Sep 15 2019 : 17:17:00 Hi Please set ImageEnMView1.MouseWheelParams.Action or ImageEnMView1.MouseWheelParamsAlt.Action to iemwZoom. https://www.imageen.com/help/TImageEnMView.MouseWheelParams.html Nigel Xequte Software www.imageen.com
