Indeed. Not with the amount of bugs they deal on the daily basis :~

Those can celebrate Programmer's Eve the day before :laugh:

Today is 256th day of the year! So congratulations to everyone on this Programmer's Day[^].

Hello, When it comes to image processing tasks, I would say that it is much easier to discuss when there are few sample pictures available (if there are no some confidentiality restrictions of course). Talking about circles ... in some cases you can simplify things a lot by finding stand alone blobs/objects in a picture and then doing further shape analysis of those ...

Hello, Did not run the C version of the algorithm you've pointed, but there are some already made implementation of thinning in C#, which are made in AForge.NET Framework[^]. One example is to use math morphology filters for this: [^]. Another is simple skeletonization filter[^].

Hello You need to use gacutil.exe for it.

gacutil.exe /i <assembly_path>

Hello Yes, you can use the above code to convert your image to 24bpp or 32bpp format (as you already know, Image.Clone does not produce this functionality, as it was expected). With 24bpp image you can use most of image processing filters.

I was observing this message board and found out the following code:

Yes, there is. Use LockBits. But, you will get troubles if you have color indexed image (like GIF). As you can see from my first article, I am using 24bpp format for color images, 8bpp indexed for grayscale images. Both formats I am processing using LockBits. And in the case of grayscale image it's rather obvious to implement brightness filter (the same logic as for 24bpp).

Hello You can try the next code: uint i = 0xABCDEF12; byte[] bytes = new byte[4] { (byte) (i & 0xFF), (byte) ((i >> 8) & 0xFF), (byte) ((i >> 16) & 0xFF), (byte) (i >> 24) }; With best regards, Andrew Kirillov, MCP x 3 Prize winner, August 2005

Hello You need to use ContectMenu property of TreeView. With best regards, Andrew Kirillov, MCP x 3 Prize winner, August 2005

Hello May be you need to try this: int.Parse( str ) or this: Convert.ToInt32( str ) With best regards, Andrew Kirillov, MCP x 3 Prize winner, August 2005

Hello You use the next code:

byte[] bytes = new byte[] { 0x41, 0x42, 0x43, 0x44, 0x45 };
string str = System.Text.Encoding.ASCII.GetString( bytes );
System.Diagnostics.Debug.WriteLine( str );

Hello. You can use the next code:

// create new image with desired pixel format
Bitmap bmp = new Bitmap(width, height, PixelFormat.Format32bppArgb);

// draw source image on the new one using Graphics
Graphics g = Graphics.FromImage(bmp);
g.DrawImage(src, 0, 0, width, height);
g.Dispose();

With best regards, Andrew

Hello Why do you think your GIF image is 32-bit ? You can check the PixelFormat property and you will see, that it's Format8bppIndexed. You can try to use ImageLockMode.ReadOnly mode or lock your image with PixelFormat.Format8bppIndexed or convert your image to 32-bit before (which will be useful if you are planning some image processing routines). With best regards, Andrew

Is it possible to produce eggs without chickens ? ;) No. C# is a .NET language, so any program written on C# requires .NET framework.

Rahul.P.Menon wrote: 4)Can we develop any application using C# alone in notepad editor and without using dotnet(including dotnet frame work) You can write your application in any editor, even in notepad if you are masochist.

Hello, To capture from your webcam you can interop Video for Windows or to use DirectShow (interop it or use managed extension of DirectX 9). You can find about interoping DirectX here on CP: http://www.codeproject.com/cs/media/directshownet.asp[^] And about VfW on C#: http://www.codeproject.com/cs/media/aviFileWrapper.asp[^] You can also look at my article Motion Detection Algorithms[^]. This application is able to work with local capture devices. For working with scanner you should google or search here on CP, because the topic was already discussed. With best regards, Andrew
