I am looking for a .net control that allows for the editing of images. The following features would be desirable:
Crop
Zoom
Pen
Line
Brush
Circle
Polygon
Full undo / redo
Measure Tool
Layers(not critical)
This control can either be Winforms or WPF, but would need to be extensible.
I am happy for it to be a commecial control or open source. If source code is also available C# is desired.
I ended up finding that an "Image annotation" control satisfied all of my needs.
I went with VintaSoftAnnotation.NET Plug-in
In my research I found others:
leadtools
atalasoft dotimage
accusoft imagegear
This would help :

I want to make an application that opens up camera, point at an image and if the image is recognized in my database, give all the corresponding info, else, nothing happens. I dont know where to start, can you give me orientation and specify what cross-platform / ios / android language should I use?
You can try OpenCV. Check for similarities to match database image and camera view. take a look at following link. similar post described there:
Checking images for similarity with OpenCV

In my WPF application I need to draw some dynamic line chart, that receives data from a background process and can be updated at runtime. I need also that graph is not static but moves while data arrives from other process.
I've read about OxyPlot and DynamicDataDisplay but the first does not work for me (see Unable to load system.core when including oxyplot in WPF window XAML) and the second has no documentation to explain how to use it.
Anybody knows another library?
Telerik, DevExpress and Xceed all have WPF charting libraries tho' they are all paid for annual licenses.
In terms of open source, you've basically got OxyPlot or the WPF Toolkit Charting 4.0 (where there is a properly ported to .NET 4.0 and including Stacked chart series) at http://dlaa.me/blog/post/9910837

I have an application which could easily be controlled by a bot over network or even on the local machine(which simuates keyboard and mouse e.g.).
I want to avoid this using a captcha. The source has to work without internet / has to be generated during runtime on the computer itself.
Is there any open-source project for this or can someone give me a code example or a link ?
I've found an article "Simple CAPTCHA, Create your own in C#" by Raymund Macaalay. It is for an ASP.NET app, but he generates a normal C# bitmap image using different random fonts in STEP2, so this should also work in your WinForms app.

I want to implement an algorithm for compressing BMP images. What library/sdk would you recommend for helping with reading a picture's pixels, and creating an image pixel by pixel?
Try this tutorial. this will help you to do normal jobs with images in a tutorial format using C#:
http://www.switchonthecode.com/tutorials/csharp-tutorial-image-editing-rotate
for working with images in pixel level see this thread :
How to manipulate images at the pixel level in C#
System.Drawing.Imaging (GDI+) http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.aspx
Could help you... It has functionality to save with saveoptions and encodings that will allow for compression.

Is there a good article or source code where I could find an WPF image rotator (moves automatically) similar to WPF carousel?
I'm not really interested with DevExpress Carousel Control for WPF. I'm only looking for a simpler approach for this one.
