The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

How to write a WebCam application using Directshow to preview and capture in portrait and landscape mode?

Asked by rahul_r_jadhav in Computer Web Cameras, DirectX Graphics & Game Programming, C++ Programming Language

Tags: Camera, Portrait, Landscape, Directshow

     I have written an application using C Plus Plus and  DirectShow that can preview and capture images in landscape mode. I dont know how to change the mode from landscape to portrait. So the application can do preview and capture for resolutions such as 800x600 or 1200x900. But what I need is, the application should also be able to do preview and capture for resolutions such as 900x1200 or 600x800. We thought of rotating the stream by 90 degrees but it isn't actually a solution.

        I tried to find the solution over net but unsuccessful. I think the Camera in itself need to support the portrait resolutions such as 900x1200 along with the landscape resolutions but I could not find a justifying referece to confirm it.

        Any help in this issue is highly appreciated.
