Zoom

Now that I have the basics set up and you have made helpful changes to the latest beta, I am starting to get into the finer details of using FRV. One of the first things that I notice I am missing is the use of the mouse to zoom. I have followed your recommendation to change the keyboard shortcuts to allow the wheel to be used to zoom in and out, but it would be so much nicer if it zoomed in on the point the mouse curser is on. As it is you zoom in with the wheel but have then to drag the image to the area you want to examine in more detail. Zooming straight to it would be much more efficient.

Looks interesting, will try to implement.

BTW, FRV has two 'Quick zoom' modes, 'Quick Zoom+Pan' (like FastStone) and 'Quick Zoom + Drag' (with traditonal scrolling). These modes are made for quick image inspection.

Yes, I use FastStone and that method is fine, and similar to Lightroom. However, your Quick Zoom modes are not as accurate as FastStone at centring the zoom view on the point that was clicked, and neither have the ability that Lightroom has to zoom on a short click and remain there until another short click returns it to normal (so you can actually let go of the mouse and it still be zoomed and also drag it around) in addition to the click and pan with it returning to normal on releasing. As you are aiming for a close link with Lightroom perhaps you should try to emulate that, as having different ways to approach a task, depending which software you currently using is counter intuitive.
However, Using Google Earth quite a bit I am also used to zooming in on a point, as I was suggesting, and I think this beats them all.
Currently I am using the scroll wheel to control zoom and Left click to zoom and pan (using it to just pan as well). This is slightly strange, but works reasonably well, but would be better if the zoom only kicked in when the image was fitted to window or smaller. If it was bigger you can assume it has already been zoomed sufficiently and that you just want to drag it around (so combining 2 operations in one click).
However, we must not forget that the big advantage and aim of this software is that it is a FAST raw viewer and if by implementing all these ideas it becomes a SLOW raw viewer it will no longer stand out as there are already plenty of those.

Thanks for report: it looks like QuickZoom+Pan works incorrect on vertical images, image position is calculated with non-rotated size in mind (so exact position is wrong). To be checked and fixed if needed.

For QuickZoom+Drag, the point clicked is centered to window, not placed under mouse pointer. To be examined too, may be it is better to keep it under mouse.

Zoom (by Wheel) with 'mouse pointer in mind' is in TODO list. May be we'll need to make it configurable option, not sure.
