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.

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

I'm looking for a graph API (open source or to buy) - that enables to draw bubbles graph from input data - but the twist is that I want the bubbles to be pictures (gif,JPEG etc.) that I'll inject (instead of bubbles) - and the pictures will be in the size of the bubble (some pictures will be relatively small others are relatively big according to the input data).
Is there such kit?
Thanks.
As eboix comments, org.jfree.chart.renderer.xy.XYBubbleRenderer would be a good starting point, although you'd have to override drawItem().

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 :
