How to swap two pixels location?

Hello every body,

I'm new here, and I'm a beginner in C++. I don't know if this is the right place to post my question [^o)], which is:

How to deal with the image's pixel to swap it's location with different pixel? 

Note:
I'm using C++ Builder5 <---[:S] Is it good to use in this area?

Ayman,

Are you using any of LEADTOOLS products?
If yes, which LEADTOOLS version (15, 16, etc.) and programming interface (.Net classes, API C DLL, C++ Class Library, etc.) are you using?

Do you mean that you want to get the color of a pixel and swap it with a different pixel? If yes, and you are using our C DLL API functions, you can use the L_GetPixelColor function to obtain the 2 pixel colors and save them into 2 COLORREF variables. Then you can use L_PutPixelColor function to change the color values of the 2 pixels by swapping their values from the 2 COLORREF variables you saved earlier.

If you mean something else, please provide me with more details about what exactly you are trying to accomplish.

hello Maen

thanks a lot for ur replay

- no I'm not using LEADTOOLS!!

- Yes that was my idea exactly, would u please tell me how to get these tools and can I use it with C++ builder 5?

Ayman,

You can use our LEADTOOLS C DLL or C++ Classes with Borland Builder.
We have functions that enable you to load, display and manipulate pixels in images (bitmaps).
For example, you could use the following LEADTOOLS functions:
- L_LoadBitmap: loads almost any type of raster image such as BMP, GIF, TIFF, JPEG and many more.
- L_GetPixelColor and L_PutPixelColor which I mentioned before.
- L_SaveBitmap: saves the image after changing it if you want.
You can also display the images using our L_PaintDC function.

If you would like, you can download the free evaluation version of LEADTOOLS v16.5 from the following page:
http://www.leadtools.com/Survey/WebEvalSurvey.asp?category=Raster

After downloading and installing the setup, you can find a C builder demo that uses C DLL functions on the following folder:
[LEADTOOLS 16.5]\Examples\CBuilder\LoadSaveDemo
