Zoom view content control

[mwpowellhtx]

Looking for a zoom view content control. That manages the mouse wheel events, as well as possibly modifier keys, control, shift, open (i.e. no keys), etc... And relay appropriate scaling to the SKElement contained within, trigger the corresponding InvalidateVisual or what not.

Update on my current progress, and a sort of code inspection. At present, I have a loose grasp that there may be some scaling issues going on, under panning scenarios. And by extension, with zoom factors. Although I am not hundred percent certain on the matter; yet.

I also think that if I can arrest a SKPoint cursor position, as well as a zoomed view SKRect, during the normal handling of keyboard mouse gesturing, that there is a natural scaling and translation that can happen from survey to radar thumb, almost for free, or with very little extra effort, approaching radar thumb PaintSurface events. That would be the most optimum possible solution, I think.

Anyway, interested to gain some peer feedback.

Slightly improved update, yes improved, but still showing indications of some sort of scaling issue, definitely also panning issue, and possibly a combination of the two. Not quite sure how to resolve those things, need some better informed eyes than mine to help diagnose the issue, and offer some guidance.

Key points, the scaling I am doing right now, is perhaps naive in nature. Additionally, I know of the algorithms involving a transformation matrix, given the scaling factors... Need to solve for the translation components, but the problem is, I do not have the B coordinates. That is precisely the point; we have A coordinates, needing to transform to the B (unknown) coordinates.

My understanding is, given the scaling factors, and translation solutions, that would properly orient the B coordinates. Need a bit of help connecting those dots, identifying the issues, and guidance informing the solution.

@mattleibow Really I am struggling a bit here, I think I am missing something, with the scaling components involved, graduating from naive scaling to perhaps a matrix linear algebra based solution, I am not certain. Just need to pick some enlightened 🧠(s) and learn what other solutions might be better suited to the problem at hand.
