Simulate eyedropper in actionscript - actionscript

I'm creating an Illustrator plugin using Actionscript and I wanted that as soon as the mouse leaves the plugin window and is in the illustrator document it would record the mouse positions and get the value of the pixel in these positions using getPixel() but the problem is that I can't get mouse position if the cursor leaves the stage, so is there a solution for this problem or it just can't be done?

Can't be done. All you can do is listen for Event.MOUSE_LEAVE, but that isn't going to help you in your situation.

Need a bigger mouse cursor

Windows 7 appears to only support 48x48 pixel mouse cursors natively. My dad is half blind, so this isn't good enough.
Looking around a little, I see that there is High DPI Cursor Changer Beta on SourceForge. Unfortunately, it states that it is limited to Windows 8 and above. Even if he did have Windows 8, I still don't think it would be big enough.
I've been thinking about some other alternatives which might get the job done. One is to use AutoHotKey to track the mouse position and type, and using that information, put up a larger bitmap under the cursor that is displayed on a click through window.
This seems doable, but I would like it if I could invert the information beneath the cursor as the inverted mouse cursor does. I'm thinking that this would require using the DirectX API, which I'm totally unfamiliar with. As I don't have a whole lot of time to devote to this, it would be great if someone could point out some key concepts and API calls so that I can move through this project as fast as possible.
I've also looked into zooming in, but seems using that is also problematic as it requires that he get it in and out of that state and zoom in and out fairly easily, which he can't as he can't really touch type and his fingertips don't have very much sensation, making it hard to navigate the keyboard effectively.
If there are any other ideas, I'd be interested in hearing about them as well.
I haven't tried Bill Myers solution, so I think that the cursors are still the max. size, but check out Bill's link: https://www.bmyers.com/public/high_visibility_cursors.cfm

How to track an opened hand in any environment with RGB camera?

I want to make a movable camera that tracks an opened hand (toward the floor). It just needs to track the opened hand but it has to also know the rotation (2d rotation).
This is what I searched for so far:
Contour- As the camera is movable, the background is unknown, even the lighting is not fixed. It's hard for me to get a clear hand
segment in real time.
Haar- It seems this just returns a rect and can't deal with rotation.
Feature detect- A hand doesn't have enough detail for this.
I am using the Opencv Unity plugin to do this.

I see another library can do something like this. Can OpenCV also do this?

Moving the mouse pointer using OpenCV

I searched a lot about finding a way to make me move the desktop cursor using OpenCV but all I found is some demos for people who already did it.
what I know is that the function setMouseCallback gives me the coordinates of the mouse and more but i need to give the mouse some positions to move into it.
So can anybody tell me how can i do it using OpenCV C++ ?
You cannot do this in OpenCV. OpenCV is a computer vision library focused around analysing and manipulating images and although it provides simple user interface (UI) elements do not get fooled into thinking it is a powerful user interaction tool.
Now, if you want to move the cursor in windows you can use SetCursorPos which I believe works on most versions:
SetCursorPos(X,Y)
e.g.
SetCursorPos(100, 200)

Delphi - mouse move simulation

How can I simulate mouse moves (from point x,y to point a,b), ideally 10 pixels / second?
I found SetCursorPos function, but this function cannot move my cursor correctly.
My goal is to move the cursor over TWebBrowser component and read hints with OCR (and find text that I'm looking for).
PS: I'm using Delphi 7.

Dragging with inertia in AS3 for dummies

I'm trying to create an inertia effect for dragging that's constricted to the x axis. I know this questions was asked before here but I couldn't understand the answer!
I'm currently using startDrag and stopDrag. I'm assuming I should add something to the startDrag function that captures the speed in which the user is moving the mouse, but I'm not sure how this is done. I guess then I'd add something to the stopDrag function that kicks in and makes the object keep moving at that speed and then come to a stop.
Any suggestions?
I've found an grat online tutorial that has the answer. I was a matter of tinkering with the code. The writer even has .fla files for download.
