The Zoom functionality is not working - with explicit call to ..ZoomIn / ZoomOut or with mouse scroll.

The control has all AutoFit, AutoShrink, AutoStretch set to FALSE.
How could that be ? What am I missing.

Here is the code ( nothing else is set in code - this is it )

object iePriponkaView: TImageEnVect
Left = 319
Top = 65
Width = 745
Height = 211
ParentCtl3D = False
BorderStyle = bsNone
MouseInteract = [miZoom, miScroll]
DelayZoomFilter = True
EnableInteractionHints = True
Align = alClient
TabOrder = 2
BitmapResampleFilter = rfBilinear
end

I'm using ImageEn version 4.1.4.

Thank you for your help.

The image is loaded to the vectorView via imageEnMView like this :

iePriponkaMView.CopyToIEBitmap( idx, iePriponkaView.IEBitmap );
iePriponkaView.RemoveAllObjects;
iePriponkaMView.MIO.Params[ idx ].ImagingAnnot.CopyToTImageEnVect( iePriponkaView );
iePriponkaView.Proc.PasteFromClipboard;


And on the ZoomIn button click event is this code
iePriponkaView.ZoomIn;

Nothing else I can find.


I have ImageEnVect on a nother form (same logic as on this non working form) and it is working OK there .. I've even copy-pasted the component -- but the result was the same - non working ImageEnVectView ( Zoom ).

There must be something wrong on your end. Zoom In and Zoom Out works perfectly fine here, and in another app you are running, so it is not ImageEn causing the problem.

I'd try to recreate the form again by dropping components on the form.. not by copy and paste.

Hi

Also please check that AutoShrink, AutoStretch and AutoFit are all False.

Hmmm .. I did not mention this before - because I didn't think it matters... BUT This form is inherited on another form (and not a single functionality is changed regarding imageEn).

SO basicaly it is like this.

1. If I create a new form - Inherited item ; Imageen ZOOM is not working.
2. If I drop a new component on this Inherited form and RE-Code all the missing functionality the ZOOM starts working again - Strange I know.

Maybe it is just a coincidence ... dunno.
