i wanted to develop a DICOM Image editor in Asp.net
are there any library available for that.
or can i do something like
create an Jpeg from DICOM editor. edit the same image with lines or shapes and convert it back to DICOM Image file is that possible? if yes how?
i am new to DICOM. hence please help me to understand the DICOM.
There are a number of DICOM libraries for .NET. Refer to this question for more info.
UPDATED: another one
As far as an ASP.NET viewer - what do you want this viewer to do. In other words, what is the target audience? Is it mobile users? Then silverlight, wcf and flash are out - the most used web-based larger-screen mobile device is the iPad, which supports none of those technologies. Is it desktop users? Flash could be the answer then, the install-base is quite high, and Flash has good support for a variety of image formats.
Do you need this viewer to be diagnostic-grade? In other words, do you need 16 bit window/level? cine loop for ultrasounds at the correct frequency? If yes, then you'll need to figure out some of this yourself. Existing mobile tools aren't so great at some of the above (specifically 16 bit grayscale).
HTML5 has some of the above capabilities, and is mobile-friendly. Anyway, start with the intended use for this tool, and that will lead you into a specific direction based on the requirements you come up with!
Here's a good place to get started:
Medical Image Format FAQ - DICOM Information Sources
An open-source library that could be suitable for ASP.NET development is mdcm that allows you to develop Silverlight assemblies that could be used from your web application.
There is also a successor to mdcm denoted fo-dicom, however I am not sure whether fo-dicom currently is applicable to Silverlight.

Could someone recommend an existing image conversion framework. I need to convert virtually all image formats: raster and vector, ms office, pdf, psd etc. Color precision is a must.
Thank you.
(edited)
Any platform, any language, but Windows is preferred. This would be a backend, so client platform is irrelevant.
I know I could find multiple frameworks to cover all the formats (already have), but idea is to have as few as possible.
Color precision is important as it is an image review system.
Imagemagick is the most complete image conversion tool I know, it has lot's of features to modify all types of images. The software works in cli and is available for any platform.
You can also find a lot of help on their forum.
Building on your key requirements:
to use the framework on your back-end,
to get the framework with an un-compromised ColorManagement precision
test the server-side suitability of a GhostScript framework.
Moving your solution's neutral-format to a PostScript level will solve all your other conversion related requirements.
Once your image-review system architecture settles on PostScript, "The Lingua Franca" for professional TypeSetting, both the conversion issue and the ColorManagement issue get out of the table.
Try ImageResizing if you can develeop on .net platform.
IMHO great piece of software!
Use Imagemagick as it can convert nearly all image formats.

I have an idea to develop a website that would help people to model 3D worlds, use 3D models and so on.
For example, based on my reseach, I could use Unity Framework to create this type of application for PC/MAC.
I am wondering if there are similar frameworks available for pure WEB?
This is my first time looking into this and I do not have any expertize in this topic. Please advise if you have any opinions or expertise in it.
Unity indeed has support for 3d on web, but it requires from user that it has installed Unity player. Users might not like that.
However, with webGL, you would have absolute control over the look and capabilities of your product, users wouldn't have to install anything new, it would all be pure web and only IE users would be damaged, because IE still doesn't have full support for webGL.
To develop with webGL you can do it from scratch, or you could use some of the existing libraries/3D engines that would speed up your work and give results much faster.
Here's a list of webGL engines: http://ffwd.typepad.com/blog/2011/04/webgl-what-flavor-is-your-engine.html, it seems that most used are Three.js, Scene.js and there is also Goo Engine (http://www.gooengine.com/).
Hope this helps.
Check out 3DTin, it does seem to deliver a part of what you want to build, using WebGL:

I am playing around with Leadtools to see how it might benefit me but i am a little frustrated with their documentation regarding how the process works. I am creating a library with methods that take an input file, convert it to pdf, add a qrcode to the file and save it and then reading the qrcode again.
Does a pdf have to be converted to an image before leadtools is
able to read the qrcode?
Does leadtools allow converting from
doc to pdf and then adding the qrcode or do i have to convert it to
an image as well?
Is there anywhere I could look at code
samples of how I can go about doing what I talked about other than
the leadtools site itself?
I am sorry to hear that you are having difficulties, but I will do my best to get you pointed in the right direction.
To answer your questions:
A1.) Yes, the PDF will need to be rasterized before the LEADTOOLS barcode engine can be used. Our barcode engine will only work with raw image data. Once the file is decompressed into raw data, we will not access the file any further.
A2.) Yes, you can rasterize Microsoft Word documents using either our file I/O methods or with the LEADTOOLS Virtual Printer. Once you have the raw image data, you can pass it to the barcode engine to write the QR code into the data. Once the barcode is written, you can then compress the image into any supported format, including (raster) PDF. You can also create a searchable PDF by running the resultant image through an OCR engine & outputting to PDF.
A3.) The LEADTOOLS SDK has a main barcode demo that should illustrate the ability of the SDK to handle the features you describe here. There are also tutorials in the help file, and various projects on our support forums. We have also created a couple different CodeProject articles here:
Multi-Platform Barcode with LEADTOOLS 18
How to Read Barcodes from Images using LEADTOOLS
You haven't mentioned here what programming language you are developing with or what the specific problem are that you have encountered. Without knowing either of those, it's difficult to get more specific into any methods or other resources to check out. For a simple raster conversion of a Microsoft Word Doc to PDF and writing a barcode, I think this would probably take between 10-15 lines of code.
If you have not already, I would highly recommend sending an email to Support#leadtools.com or open a live chat with the LEADTOOLS Support team from LEADTOOLS.com. We can get into more specifics there and help you more directly with any issues you are encountering.

I tried adding this as a comment, but it is apparently too long for that. So I have added it as another answer.
Even if you are building a DLL, I would suggest starting out building a simple demo with a view of the image so you can see what exactly is happening to the image. Once you are comfortable that the image is being modified the way you want, then implement that code in your own library.
Also, I would recommend testing out the toolkit with the provided main demos. The demos are there to illustrate the different options you have access to in the code. If you can accomplish what your application or library will need to do through the demos, then it would be worth your time to begin coding specifically what you need. You might even need to use multiple demos to verify the tools can accomplish the goals that you have. You have all the toolkit code for the demos, so you can take them apart and use the specific pieces that you need in your application.
If you are having trouble identifying which demos to try out or whether the toolkit has the specific functionality that you need, your best bet is to contact Tech Support directly to ask. We are here to help get you pointed in the right direction.
To get down to brass tacks, the source of the image data is not all that important from the perspective of the barcode engine. It needs a RasterImage handle (raw image data) to write the specified barcode. Whether the image data is created on the fly, read from file, or generated from a scanner, it does not make a whole lot of difference.
To find the main .NET barcode demo, I would start out by going to the LEADTOOLS shortcuts. To get there, go to the Start menu -> LEADTOOLS -> Help and Demos. The shortcuts are broken down by programming language, feature, and then the base toolkit. You should be able to find the WinForms .NET barcode demo here:..\Shortcuts.NET Class Libraries.NET Framework\01 Imaging\07 Barcode
Our toolkit example is a .NET WinForms project, but it will work in ASP.NET also.
Here are some links to tutorials if you want to dig right into the code:
Loading and Displaying an Image in WinForms
Reading Barcodes
HOW TO: Load and Display an Image with WebImageViewer
There was also this recent code tip posted illustrating how to read and write UTF-8 characters in a QR barcode.
We provide both .NET 2.0 and .NET 4.0 DLLs for our barcode engine. Both of these work within Visual Studio 2012.
I want to make a charting control for an embedded device using Silverlight for Windows Embedded. Currently i am planning to use line shape for drawing the graph.
My question is if its a good approach(performance wise) or should i look for other options.
Or if any controls are available for SWE.
Thanks
Silverlight is not a proper answer to drawing charts on an Windows Embedded Compact device. You should go for using (or creating) a native GDI element. If performance is very important (e.g. for a fast-updating chart), you might also consider DirectDraw.
The best way in a commercial project would probably be to use a readymade component, such as this one.
You can find somebody else's experiences and advice here for pointers to what to look for when doing this yourself. If you expand your post with more details about what you are actually trying to achieve, I might give you a more detailed response.
The answer is stop using Silverlight, since Microsoft is abandoning the product. Do it in Flash—or better yet, use HTML5 and JavaScript.
In recent windows embedded applications that use windows universal apps I would highly recommend oxyplot.

These plots are the best I've found on the internet so far and very easy to use. Best of all they are free. You can get these using a NuGet Package manager which makes getting updates fairly simple.
I need to create a photo gallery for a website running IIS 4.0 or IIS 5.0 (im not sure which). It needs to display a low resolution version of the gallery to anyone, and it must show both the low and high resolution images for "priviledged" users. So I need access priviledges, photo albums and once the site is complete, the person I am doing this for needs to be able to upload their own images to the gallery. It also needs to have a minimal interface as it needs to be integrated into an existing website.
So I need some advice on this with the direction I should approach it.
Does anyone know if their is a customisable gallery out there that can do something like this, such as Coppermine or Jgallery or something. The alternative is to use a web framework like Ruby on Rails, CodeIgniter or Sproutcore (each which require learning a new language). The framework would be more work, but the existing galleries may not be customisable enough. The important bit is the user privileges in an admin panel.
I am relatively new to "web programming", although not new to normal/games programming. I have a few years experience with C/C++ OpenGL and Java. I have also read up on MVC etc, and did hello world with sproutcore, so I kinda get the idea. Although learning a framework is a much heavier investment.
What are your thoughts?
If you don't want to re-invent the wheel you could use Gallery2 (requirements here). It runs on IIS -- you'd just need PHP and a database. It's very configurable (including user accounts), has lots of plugins, and its open source if that's not enough. Also, the development and support communities are large and active.
you could always go the route of Dotnetnuke and then use Ventrian's Simple Gallery module (http://www.ventrian.com/Products/Modules/SimpleGallery/Demo.aspx)
Using DNN offers a ton of functionality, including the security you need, and it would save you from doing any web development.
If you are a bit more adventurous, try Smaltalk based Aida/Web and specially Aida/Scribo CMS (currently still in beta), which include Gallery so called scriblet as well. Scribo scriblets are otherwise web components which you can include directly into a text. You therefore add a gallery directly into a surronding text. See for instance a presentation as a Gallery for example.
I would recommend my own but... If it weren't for the low/high resolution thing with permissions I think it would fit the rest of your needs. I'm going to leave a link just in case you want to take a look at it:
nzFotolog
It's also open-source (although the license is not the best) and you can change it at will if you want. The code itself is clean and self-explanatory. The downside is that I haven't developed it for some time now :(
Having faced a similar dilemma myself I have to say that I found Gallery2 and Coppermine both far too all-encompassing and difficult to customise to the degree I would have wished. I ended up rolling my own using straight, procedural PHP with various bits of jQuery for the GUI fancy bits. At the same time I was able to bake in some e-commerce and data gathering for my wedding photography clients, ending up with something which exactly matched my needs. Certainly, the gallery aspects of this project were, for a complete programming (although not HTML) neophyte, the least challenging - it's exactly the sort of thing PHP is made for.
I'm now taking my first faltering steps with CodeIgniter for my next project (photoblogging software) and I can already see that the framework would make a gallery project very quick, simple and secure.
