I think so. I just bought an OpenCV book a few days ago and started reading it and I recall them mentioning something about a yahoo group. I'll probably join it after I read a little more of the book.

I have a copy of that book coming. Last I checked, FedEx was driving it around the Midwest. Nathan found the chapter on camera calibration helpful.

Something wrong with the 322,000 examples a simple Google search turns up?

Hours and hours of endless research on the internet finally revealed the following result:
TreeMaker 5 (source included)[^]
Just kidding, 3 seconds with Google and I found it. Maybe you should first learn, how to use Google?

Hi,
I've been trying to display a transparent rectangle using standard Win32/GDI coding now for at least an hour. I've searched in tons of places, but I just can't get it working. This is my current code:
RECT r = GetRect();
HBRUSH brush = CreateSolidBrush(RGB(0x00, 0xD7, 0xEC));
FillRect(hdc, &r, brush);
DeleteObject(brush);
That displays fine, but it displays a completely opaque rectangle and I'm clueless on how to go about making it transparent.
Any help is very much appreciated!
Thanks,
Martin

I wouldn't recommend using GDI for transparency - it wasn't designed to accommodate such features.
Instead, I'd take a look at GDI+, an extension of the GDI library and is included with versions of Windows XP upwards, but can also be distributed as an executable with your app if the target OS is lower than this. It's also a good library to familiarise yourself with for the future due to its diverse graphics manipulation functions included.
Something like this could create a semi-transparent black rectangle:
SolidBrush solidBrush(Color(150, 0, 0, 0));
graphics.FillRectangle(&solidBrush, 0, 0, 100, 50);
Take a look more at the SolidBrush() class, the FillRectangle() method.
Regards,

Thanks, I'll check it out.

ummm....you are explicitly creating an opaque brush and then filling
a rect with it. There's nothing transparent about any of that 
If you are trying to draw a hollow rect...
HPEN pen = CreatePen(PS_SOLID, 1, RGB(0x00, 0xD7, 0xEC));
HGDIOBJ oldpen = SelectObject(hdc, pen);
HGDIOBJ oldbrush = SelectObject(hdc, GetStockObject(HOLLOW_BRUSH));
Rectangle(hdc, r.left, r.top, r.right, r.bottom);
SelectObject(hdc, oldpen);
SelectObject(hdc, oldbrush);
DeleteObject(pen);

I know something about OpenCV. Do you have a specific question?

Guess that was a rhetorical question.

I need to create a visualization of the progress of machining a part. The part is a relatively simple shape made up of cylinders and conical sections and only a side 2D view, no texture and minimal if any shading, for now. I will have to put the graphic in an ActiveX control or VBA form. This is my first time going beyond the MFC-GDI and am wondering what direction to start in and why.
Thanks in Advance

Hi all!
Please help me with my question. I'd like to draw .bmp file on openGL surface. My openGL surface is GL_TRIANGLE_STRIP set. Now I can load bitmap on the surface but it is not I want. Now I'm receiving the surface with tilled images. But I'd like to fit my picture on whole surface.
Thanks.

Hi all,
I'm trying to find a set of calculations that describe different muscles. My goal is to find some formula that can be tweaked a little bit, so that the dimensions end up looking different. For example, the shoulder muscle--modify one variable and it looks beefier, modify another and it gets wider. Anybody know where I can find some formulas for this kind of thing?
Thanks for your time,
Michael Fritzius

Thanks for U're sugestion! 
I write 2D game, I try write the game using GDI, but some times the program run slowly!  , so I try write the game using direct X, but until now i dont understand about it!

If you Google "directx VB.NET' you'll find a link to an older DirectX
SDK that has VB.NET samples in it, along with all the DirectX documentation.
You're going to need the DirectX SDK anyway

I suggest you learn SDL.. its fast, portable.. and easy to learn
I made a tetris game using it. It was amazing to look at your game run both on windows and linux...
DirectX/DirectDraw is good... but I think SDL is better for your needs, most 2D needs. and you can even do 3D by mixing OpenGL with it.
