Zoom after Stretch and ScrollBars

Hi

i’m not sure if its intentional made not to zoom, if SizeMode is not Normal once i change Size Mode to Stretch or Fit zoom doesn’t work

i was trying out this control, where i changed Dock : Fill and SizeMode: Stretch for image to fit within resizable winform. but how can be enable zoom after this ? also is it possible to hide scrolls bars while maintaining image to be at center (AutoCenter : True)?

Thanks

Update: below code didn’t work!

imageBox.HorizontalScroll.Visible = false;
imageBox.VerticalScroll.Visible = false;

I had a look and I did spot an issue where the sample code didn’t work properly if the image was very small so even after the first zoom the stretch rule came into play thus resetting the zoom level. I’ll see if I can find a bit of time to play with the sample further.

Thank you very much for time & code.

i don’t want to bug you but, it worked if my imageBox size is less than some value, if i gradually increase the size of imageBox, it doesn’t work. i was debugging, below values are when zoom didn’t work (imageBox1.SizeMode before zooming is Stretch)

//these values are from SetSizeMode func, triggered from MouseScroll Event
zoomFactor = 2
viewSize.Width=1400
viewSize.Height = 805
scaledWidth = 1282
ScaledHeight = 962
imageSize.Width = 641
imageSize.Height = 481

probably we have to manually increase zoom factor little bit here right? how much amount and when?

here’s values when zoom work (imageBox1.SizeMode before zooming is Stretch)

zoomFactor = 2
viewSize.Width=1275
viewSize.Height = 805
scaledWidth = 1282
ScaledHeight = 962
imageSize.Width = 641
imageSize.Height = 481

i haven’t set any padding valuesi tried to modify the if statement. then zoom happens but background pixel grid will be noticed
