Hello folks, I have a rather large image, whose size is around 6000 x 5000 pixels... I would like to perfom image normalization and other such operations...which include some mathematical calculation for each pixel.. But when I do this on my image, it take about 20 mins to finish... How to speed it up...?? Here is the normalization code which I am running.. public void NormalizeImage(ref Bitmap objBitmap, int iMaxColor) { DateTime dt = System.DateTime.Now; System.Diagnostics.Trace.WriteLine(" Normalizing Image: " + dt); int iX = objBitmap.Size.Width; int iY = objBitmap.Size.Height; int iMaxINTColor = 16777215; try { for (int i = 0; i < iX; i++) { for (int j = 0; j < iY; j++) { int iPrevColorVal = objBitmap.GetPixel(i, j).ToArgb(); //if (iPrevColorVal < 0) // iPrevColorVal = iPrevColorVal * -1; int iNormalizedVal = System.Convert.ToInt32(Math.Pow((iPrevColorVal / iMaxColor), 1)) * iMaxINTColor; objBitmap.SetPixel(i, j, Color.FromArgb(iNormalizedVal)); } } } catch { System.Diagnostics.Debug.Assert(false); } DateTime dt2 = System.DateTime.Now; System.Diagnostics.Trace.WriteLine("Done Normalizing Image:" + dt2); }

Yeah... VC is like eating a badly cooked meal, While Matlab is like visting the Giza pyramids on a month long sub-saharan tour :P So i chose matlab! :)) Btw the squid....welll its like when one tries to eat the pencil rubber in childhood days...its the same with a squid...just the difference being that you dont get rubbed by your mommy for wasting your pencil eraser... :P Btw I have tried raw fish, i.e. sushi ; Live fish, swirling in a pond of blood...so eating squid is like the "aaloo wala paratha or bieryanee" in pakistan :P

Hi, Guys where to put matlab question? Thanks! safee

yes i have it in a bstr...now i need to break that string into 32k segments..for further manipulations.. how to do it? regards safee

hello there .. there is a slight problem that i am facing with strings greater then 32k i have a variant bstr containing a string which is greater then 32ks.. 1. how do i store this thing? into a buffer?, but then how do i get the size of the bstr string so that i can create a buf of that size? 2. how do i truncate this bstr string into strings of sizes 32ks? thanks for the time regards

any place to get detailed info on variant arrays..and how to use them??

hey thanks ian.. one more thing plz..how do i then get the value from this variant? thanks

u have forgotten the last line return pvResult.bstrval; (offcourse after making your method of the type returning bstr) and if u already have it there in your code..then take a look at the following code, also if it doenot work then try looking into the dispatch map..have u given the correct VTs there for the return type?? //******************************* //body of a method returning BSTR DISPPARAMS * DispParam1 = new DISPPARAMS(); EXCEPINFO excep; UINT nArgErr; VARIANT *pVarRes = new VARIANT(); DispParam1->cArgs = 0; //number of arguments DispParam1->cNamedArgs = 0;// Number of named arguments. DispParam1->rgdispidNamedArgs = NULL; // Dispatch IDs of named arguments. IF1BookImpl::Invoke(DISPID_F1_Text, IID_NULL , ::GetUserDefaultLCID(), DISPATCH_PROPERTYGET, DispParam1, pVarRes , &excep, &nArgErr); delete DispParam1; return pVarRes->bstrVal; //******************************* regards safee

hi there people.. i lost my cd which came along Inside Ole (MS press) by Kraig BrockSchmidt...any body with a copy... or any link? many thanks

yes..but the drive is already formated using NTFS..and no file is greater the 800 mbs..

hi there.. Thanks for your time.. I am facing strange problems with my 160 Gb seagate hard disk. Firstly it was showing it as 134 Gbs , then i installed the SP4 for win 2k Adv Svr. Now it shows it as 160 Gbs. But when the data inside it exceeds 134 Gb, It starts writing on the previously written files hence "pasting" new video data inside the alrady existing videos :)) now when i play that old video , some parts of it are gone and contain new videos from other files which i recently pasted :( PLZ PLZ help me in this..it has been a month..seagates own drive wizard doesnot help too.. thanks regards
