Wed, 24 Feb 2010 18:59:50 -0500 http://www.wischik.com/lu/programmer/1bpp.html Fascinating! I'm getting the same results, i.e. your Bitonal code is twice as fast as the GDI approach. Very nice. Tue, 16 Feb 2010 16:07:19 -0500 http://www.wischik.com/lu/programmer/1bpp.html Hi, this is really interesting. I was using a similar strategy like Bob Powell's which I lent from http://www.codeproject.com/KB/GDI-plus/BitonalImageConverter.aspx. ConvertToBitonal first copies the BitmapData to a byte[] where processing can be done without Interop. Obviously I was anxious to see how it compares to your code. nbsp; And here are the results (tada!): nbsp; GDI conversion time: 3209ms FAQ conversion time: 8032ms Bitonal conversion time: 1461ms lt;---- this is ConvertToBitonal (can you believe it?) nbsp; I modified the test so it can handle several images (I used 10 Jpegs from my cam for this particular test). I also used Stopwatch rather than TimeSpan/DateTime for measuring. nbsp; Now, I am a bit confused by the results. From all your explanations about the the graphics hardware accelerator card and so on I was convinced that your code would be way faster. Do I have a crappy graphics card? Can someone test this? Here comes the modified code, first Main, followed by ConvertToBitonal (rest stays the same):- nbsp; nbsp; static void Main(string[] args) nbsp; { nbsp; string[] files = Directory.GetFiles(".", "*.jpg", SearchOption.TopDirectoryOnly); nbsp; //Bitmap b = new Bitmap("test.jpg"); nbsp; //SplashImage(b, 0, 0); nbsp; // nbsp; Stopwatch sw = new Stopwatch(); nbsp; long tsFaq = 0, tsLu = 0, tsBitonal = 0; nbsp; Bitmap b; nbsp; for (int i = 0; i lt; files.Length; i++) nbsp; { nbsp; b = new Bitmap(files[i]); nbsp; // nbsp; sw.Start(); nbsp; Bitmap b2 = ConvertToBitonal(b); nbsp; sw.Stop(); nbsp; tsBitonal += sw.ElapsedMilliseconds; nbsp; sw.Reset(); nbsp; //SplashImage(b2, 400, 200); nbsp; b2.Dispose(); nbsp; // nbsp; sw.Start(); nbsp; Bitmap b0 = CopyToBpp(b, 1); nbsp; sw.Stop(); nbsp; tsFaq += sw.ElapsedMilliseconds; nbsp; sw.Reset(); nbsp; //SplashImage(b0, 200, 100); nbsp; b0.Dispose(); nbsp; // nbsp; sw.Start(); nbsp; Bitmap b1 = FaqCopyTo1bpp(b); nbsp; sw.Stop(); nbsp; tsLu += sw.ElapsedMilliseconds; nbsp; sw.Reset(); nbsp; //SplashImage(b1, 400, 200); nbsp; b1.Dispose(); nbsp; b.Dispose(); nbsp; } nbsp; Console.WriteLine("GDI conversion time: {0}ms", tsFaq.ToString()); nbsp; Console.WriteLine("FAQ conversion time: {0}ms", tsLu.ToString()); nbsp; Console.WriteLine("Bitonal conversion time: {0}ms", tsBitonal.ToString());

I have found that if I call OpenAddressBook without being logged into the Outlook front end the call fails and GetLastError is: nbsp; The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action. MAPI was unable to load the information service EMSABP.DLL. Be sure the service is correctly installed and configured nbsp; Do you think there is any way around this? Tue, 5 Jan 2010 08:36:40 -0500 http://www.wischik.com/lu/programmer/get-image-size.html searched the whole web for this thanks :-) Wed, 30 Dec 2009 23:10:45 -0500 http://www.wischik.com/lu/programmer/ Genious.... thanks. nbsp; Eugene Thu, 24 Dec 2009 19:31:18 -0500 http://www.wischik.com/lu/programmer/unison-ssh.html This way works, using key based authentication (rather than clear-text password). Follow the instructions for puttygen here, to put your key in the server's authorized_keys file: http://the.earth.li/~sgtatham/putty/0.58/htmldoc/Chapter8.html#puttygen-generating. Make sure that you save your private key as well, as "id_rsa.ppk". Check that it works, using ssh.exe or plink.exe. In your unison profile, stick the following lines: sshcmd=ssh.exe sshargs=-i id_rsa.ppk nbsp; This will cause plink (via the exe above) to use the key specified with the "-i" option to connect. This is based on the post above with the clear text password. Thu, 24 Dec 2009 15:48:18 -0500 http://www.wischik.com/lu/programmer/1bpp.html You have saved me. Great work. Thanks Mon, 21 Dec 2009 11:38:59 -0500 http://www.wischik.com/lu/programmer/1bpp.html Thank you! Sun, 20 Dec 2009 23:46:12 -0500 http://www.wischik.com/lu/programmer/unison-ssh.html For those having problems with typing the password, instead of this ssh.exe wrapper I run unison on windows to linux as follows. Links for the steps below are at http://palintech.blogspot.com/2009/05/unison-on-windows.html and at http://www.mcpressonline.com/tips-techniques/linux-open-source/techtip-windows-and-linux-file-synchronization.html nbsp; In a nutshell, just put *both* the unison-gtk-gui-exe and ssh.exe of your choice in same \GTK.x\bin folder. Shortcut (*.lnk) files and cmd or bat files can run unison with ssh from this folder. nbsp; 1. Install Pidgin (which installs GTK). nbsp; 2. Download the unison windows binaries and put the two exe files in the GTK directory: nbsp;("C:\Program Files\common\GTK.0\bin" in my system). Right-click on the unison-GUI-exe, and send-to-desktop (or pin to taskbar). Optionally add the shortcut (*.lnk) file to the Start menu for all users. Right-click on the shortcut and verify the "Start in" location is same ..\GTK.x\bin folder. nbsp; 3. Instead of the ssh.exe wrapper above I have been using a non-commercial "SSH Secure Shell 3.2.9" The default install will work, but I like to make two changes from the default choices: nbsp; (a.) Install to c:\program files\SSH\ instead of the horribly long path they use. nbsp; (b.) I uncheck the box to add the install location to the path. (If I need to run ssh from the command line, I use cygwin, and don't want any confusion as to which ssh is run). nbsp; Per http://www.ssh.com/support/downloads/secureshellwks/non-commercial.html "You can still download the older SSH Secure Shell 3.2 non-commercial source code and Windows Client free of charge from various anonymous ftp sites around the globe for purposes of EVALUATION, NON-COMMERCIAL USE, AND UNIVERSITY USE as defined in the license agreement." nbsp; 4. In the install directory you'll find ssh2.exe file. Copy it to ..\GTK.x\bin then rename it from ssh2.exe to just ssh.exe (because unison is looking for ssh.exe). nbsp; When you fire up unison-gui with one root being an ssh destination, look for a 2nd black command window asking for your ssh password. Click on that window, enter the password, and unison will then proceed. nbsp; I'll post more details and check if it can do different ports or keys in a follow-up post. nbsp; Sat, 19 Dec 2009 17:32:21 -0500 http://www.wischik.com/lu/programmer/editable-web/ Fri, 11 Dec 2009 12:03:50 -0500 http://www.wischik.com/lu/programmer/1bpp.html Hi, nbsp; i have to draw a rectangle box in the given 8bpp indexed image. so i use the " g.DrawImageUnscaled(img, 0, 0)" method to generate a 32bpp image from the given 8bpp indexed image.. then i use draw method of c# graphics.. then copy the 32bpp image back to 8bpp image using the code given here. all are working well except one thing which bothers me very much is the file size.. it got reduced almost half of its original size. and if i use the rainbow palette the 2MB file is reduced to 380kb. if i use the gray scale(the above code as it is) am getting 1MB file. i need to show the rectangle in color red. with the rainbow palette, am getting red but am worried why the file size is reduced this much. pls guide me.

The most enjoyable? nbsp; 3. If you could have any one tool to make your job easier, what would it be? nbsp; 4. Are analog engineers truly different from digital engineers? nbsp; 5. What made you choose analog design? nbsp; 6. What applications are you working on; consumer electronics, wireless communication, networking, power management, etc., etc.? nbsp; 7. What process technology are you working in? nbsp; 8. If you have been doing analog for a while, do you think thetools have gotten better or stayed the same? nbsp; 9. Do shrinking processes make analog design more difficult? nbsp; 10. What part of your job do you wish you could hand off to someone else to do? nbsp; 11. How does it feel to get working silicon back for a new design? Is that the buzz that keeps you doing this, or if not, what is? nbsp; 12. Do you worry about digital taking over? nbsp; 13. Do your designs represent just one (critical) part of a mostly digital chip? nbsp; 14. How do you interface to the digital engineers? nbsp; 15. Do you work in digital as well; use programming or modeling languages: Verilog, Verilog-AMS, etc.? nbsp; Subscribe for daily updates. href="http://techdockets.com" nbsp; Tue, 9 Jun 2009 18:18:09 -0400 http://www.wischik.com/lu/programmer/editable-web/documentation.html Sun, 7 Jun 2009 11:11:40 -0400 http://www.wischik.com/lu/programmer/editable-web/documentation.html ljkj Sun, 7 Jun 2009 11:11:00 -0400 http://www.wischik.com/lu/programmer/ Zip utils is great.

Tue, 20 Jan 2009 17:20:46 -0500 http://www.wischik.com/lu/programmer/webform.html Well thanks for the reply Lucian, but problem still persists. That might be because Mingw does not have mshtmhst.h and mshtmdid.h in ./includes. nbsp; Secondly, if you get some time to ddownload Dev C++ IDE (small in size) and test it, it would be big contribution, becuase almost all MingW users rely on some browser embedding DLL files, and link them explicitely (including me). I am WINAPI developer but never got into COM. I wrote RAD C++ GUI Library, and wanted a way to have Browser class (too) included in it, but no luck because of lack of support in headers available with Mingw. nbsp; Will be waiting for your response. nbsp; Ali (support@image-host-script.com) Fri, 16 Jan 2009 17:31:03 -0500 http://www.wischik.com/lu/programmer/webform.html Well thanks for the reply Lucian, but problem still persists.

Then it works for me. nbsp; Tue, 12 Aug 2008 00:37:50 -0400 http://www.wischik.com/lu/programmer/vbdev/variance-introduction.html It seems to me that declaration-site variance (as implemented in the CLR, and now proposed for C# and VB.NET) is less useful than call-site variance (as implemented in Java using wildcards). Here's why: stop for a moment and think, how many of BCL generic classes could actually be converted to use this feature? There's IEnumerable lt;T gt;, alright - but what else? ICollection lt;T gt; is right out, because it is IEnumerable lt;T gt; (and hence covariant), but it also takes T as an argument for Add() (which is contravariant) - the intersection of those is invariant. The same goes for all interfaces further extending ICollection lt;T gt;, such as IList lt;T gt;. nbsp; On the other hand, with wildcards, I can deal with ICollection lt;T gt; either in covariant or contravariant fashion: for example, only using GetEnumerator() and Count - a typical real-world scenario - is covariant; only using Add() is contravariant. You can do this with declaration-site variance too, but you have to split every interface into its covariant and contravariant parts, and I doubt the BCL team would do it at this point; besides, it relies upon interface designers to do the right thing, and gives the user no recourse if they don't. Mon, 11 Aug 2008 04:13:25 -0400 http://www.wischik.com/lu/programmer/vbdev/variance-introduction.html It seems to me you only need to have one key work Like x as CLONE List(Of T) on function call. Then in the scope of the method x will reference clone of List(Of T). Everything works as normal. Modifications of list are bound into scope of the method or object and will not have effect callers list. Furthermore modifications to objects in the list will persist out of scope which is porsumably is a desired result. This would allow stuff like is. nbsp; Class Fruits nbsp; Public Property Washed() As Boolean nbsp; Public Property Eaten() As Boolean End Class nbsp; Class WashedFruitList nbsp; Private mList As List(Of Fruits) nbsp; Public Sub New(ByVal NewList As List(Of Fruits)) nbsp; For Each Fruit As Fruits In NewList nbsp; Fruit.Washed = True nbsp; Next nbsp; mList = NewList nbsp; End Sub nbsp; Public Sub EatList() nbsp; For Each Fruit As Fruits In mList nbsp; Fruit.Eaten = True nbsp; Next mList=New List(Of Fruits) nbsp; End Sub nbsp; Public Sub Add(ByVal itm As Fruits) nbsp; itm.Washed = True nbsp; mList.Add(itm) nbsp; End Sub nbsp; End Class . . .

Thu, 7 Aug 2008 16:28:43 -0400 http://www.wischik.com/lu/programmer/vbdev/variance-introduction.html VB Variance Co- and Contravariance This is the first in a series of posts exploring how we might implement generic co- and contra-variance in a hypothetical future version of VB. This is not a promise about the next version of VB; it's just one possible proposal, written up here to get early feedback from potential users. Look at the above code. You'd think it should work. It's a common enough scenario: there's a library function which handles some kind of data type, but you've inherited from that type for your own purposes. How can you pass a collection of your own inherited type into the library function? We're considering a VB language feature to support this kind of conversion. The topic is called "Co- and contra-variance", or just "variance" for short. Variance has actually been in the CLR since 2005 or so, but no one's yet released a .net language that uses it. There are other languages with it, though. Here are some links to what people have written on the to...

Thanks Wed, 5 Dec 2007 23:21:54 -0500 http://www.wischik.com/lu/programmer/1bpp.html Great stuff, thanks! nbsp; The only strange thing I encountered was color quantization when converting to grayscale (even with the palette you used). I created a 256x256 bitmap and filled it with horizontal lines starting from (0,0,0) to (255,255,255) and after conversion to 8bpp the resulting image included only something around 20 gray levels. I checked the color table selected into the DC and everything looks ok, but still quantization occurred. nbsp; For now I added another method for recalculating the gray image after it's created by the CopyToBpp method (see below). I'm not sure what causes the problem or if I'm doing something wrong. nbsp; nbsp; private static void Calc8BPPGrayscale(Bitmap bmpSrc, Bitmap bmpDst8BPP) nbsp; { nbsp; if (bmpSrc.Size != bmpDst8BPP.Size) nbsp; { nbsp; throw new System.ArgumentException("Destination size mismatch", "bmpDst8BPP.Size"); nbsp; } nbsp; if (bmpDst8BPP.PixelFormat != System.Drawing.Imaging.PixelFormat.Format8bppIndexed) nbsp; { nbsp; throw new System.ArgumentException("Format8bppIndexed", "bmpDst8BPP.PixelFormat"); nbsp; } nbsp; if (bmpSrc.PixelFormat != System.Drawing.Imaging.PixelFormat.Format24bppRgb nbsp; bmpSrc.PixelFormat != System.Drawing.Imaging.PixelFormat.Format32bppArgb nbsp; bmpSrc.PixelFormat != System.Drawing.Imaging.PixelFormat.Format32bppRgb) nbsp; { nbsp; throw new System.ArgumentException("Format24bppRgb or Format32bppArgb or Format32bppRgb", "bmpSrc.PixelFormat"); nbsp; } nbsp; nbsp; int width = bmpSrc.Size.Width; nbsp; int height = bmpSrc.Size.Height; nbsp; Rectangle rect = new Rectangle(0, 0, width, height); nbsp; BitmapData bmpData = bmpSrc.LockBits(rect, System.Drawing.Imaging.ImageLockMode.ReadOnly, bmpSrc.PixelFormat); nbsp; BitmapData bmpData8 = bmpDst8BPP.LockBits(rect, System.Drawing.Imaging.ImageLockMode.ReadWrite, bmpDst8BPP.PixelFormat); nbsp; int iPixelWidth = bmpSrc.PixelFormat == System.Drawing.Imaging.PixelFormat.Format24bppRgb ? 3 : 4; nbsp; nbsp; unsafe nbsp; { nbsp; byte* pScan = (byte*)bmpData.Scan0.ToPointer(); nbsp; byte* pScan8 = (byte*)bmpData8.Scan0.ToPointer(); nbsp; for (int y = 0; y lt; height; y++) nbsp; { nbsp; byte* pPixel = pScan; nbsp; byte* pPixel8 = pScan8; nbsp; for (int x = 0; x lt; width; x++) nbsp; { nbsp; byte gray = (byte)((*pPixel + *(pPixel + 1) + *(pPixel + 2)) / 3); nbsp; *pPixel8 = gray; nbsp; pPixel += iPixelWidth; nbsp; pPixel8++; nbsp; } nbsp; pScan += bmpData.Stride; nbsp; pScan8 += bmpData8.Stride; nbsp; } nbsp; } nbsp; nbsp; bmpSrc.UnlockBits(bmpData); nbsp; bmpDst8BPP.UnlockBits(bmpData8); nbsp; } nbsp; Sun, 2 Dec 2007 05:01:34 -0500 http://www.wischik.com/lu/programmer/1bpp.html very nice it's so fast thanks Sat, 24 Nov 2007 11:01:49 -0500 http://www.wischik.com/lu/programmer/eye-on-the-web.html Hello, is there a way to change the 10 minutes to 2 minutes ?

The thing is, Unison needs SSH and that isn't so straightforward under Windows. Many people instead use the almost-equivalent Plink and then have some kind of wrapper around it. Unison-ssh is a particularly convenient wrapper. Using it Download ssh.exe (320k, for Windows) To install : place it in your windows directory. You'll also need to have installed Unison. Before running for the first time: in a command window, do ssh username@hostname for the host you're synchronizing with. This will sort out keys and assure you that it's working. Read the unison docs for an explanation. To run : run unison as normal. It will invoke ssh behind-the-scenes. About it Unison-ssh is a wrapper around plink with some nice features.

Mon, 23 Jul 2007 15:36:56 -0400 http://www.wischik.com/lu/programmer/editable-web/documentation.html Markup blocks If you hold down the Control key while you click on a block, it will go straight into raw markup editing rather than the WYSIWYG editor. In fact, it'll first fetch the exact page source code from the webserver before giving it to you to edit. This way it preserves your formatting perfectly. You can make a block so it only does markup, i.e. prevent users from accidentally editing it in WYSIWYG mode. Do this by enclosing it inside div editable="markup" ... /div . Create a "code block" by clicking on the CODE button in the WYSIWYG toolbar (or, in raw markup mode, enclose it with pre editable="code" ... /pre ). A code block again operates on raw text, and preserves the formatting of that text. It also provides Fri, 20 Jul 2007 17:43:07 -0400 http://www.wischik.com/lu/programmer/editable-web/download.html tag to its header (again, pointing to where you unzipped to).
