Hi Member 4708266, Are you by chance looking for a program to compare two .gif files using C++? [added] BTW There is the following function

BOOL PleaseCompareTheseGifFiles(LPCTSTR szGifAFilename, LPCTSTR szGifBFilename);

exported by the CompareStuff library available for free on www.freproductz.cpallini.com[^]. :-D [/added]

You did not mention the magic site :D

Regards, Sandip.

Your request is rather vague. What do you want to compare, size of the files, content,...?

CPallini

Fixed. :-D

You're so mean... Isn't the name of the function PlzComparezDaFilez(..) ?

With the above name it is exported by the DLL only if you compile it defining the SMS_SLANGZ symbol. :)

You are our winner because your site doesnt has any limited for generate code! :-D

Don't forget that is ALL :rolleyes: free stuff! :laugh:

I want to compare content of two .gif files using c++ win32 APIs. Size of two .gif files may be different, but if content is same, the our API should return true as they are same. Please reply me soon, it is very very URGENT.I have tried using LoadImage() and memcmp() APIs, but failed.If possible please give me the code. Thanks in Advance...

You need to two loops for width and height and then you must be check pixels of two gif files of course this wasy is very slow.

I found the code as follow.But it isn't working fine.Please tell me the necessary modifications ASAP. int main() { HANDLE hBitMap = LoadImage(0, "img.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE); BITMAP bitmap; GetObject(hBitMap,sizeof(BITMAP),&bitmap); int size = bitmap.bmHeight*bitmap.bmWidth*bitmap.bmBitsPixel/8; BYTE *lpBits = new BYTE[ size ]; GetBitmapBits((HBITMAP)hBitMap,size,lpBits ); HANDLE hBitMap2 = LoadImage(0, "img2.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE); BITMAP bitmap2; GetObject(hBitMap2,sizeof(BITMAP),&bitmap2); int size2 = bitmap2.bmHeight*bitmap2.bmWidth*bitmap2.bmBitsPix el/8; BYTE *lpBits2 = new BYTE[ size2 ]; GetBitmapBits((HBITMAP)hBitMap2,size2,lpBits2 ); int ScreenWidth = bitmap2.bmWidth; int ScreenHeight = bitmap2.bmHeight; int numOfCard = 1;int x, j, k; int cardHeight = bitmap.bmHeight; int card_line_length = bitmap.bmWidth; for( i = 0 ; i < ScreenWidth; i++ ) { for( j = 0 ; j < ScreenHeight; j++ ) { for ( k= 0; k < numOfCard; k++ ) { int tmpY = j; for ( x = 0; x < cardHeight; x++ ) { if ( memcmp(lpBits2[i][tmpY],lpBits[x], card_line_length ) != 0 ) break; // we didnt find macth of a line tmpY++; // move to next line } if ( x == cardHeight) { cout << "found"; } } } } system("PAUSE"); return 0; }

I dont have any compiler for text your code but you can use of a simple code instead this code but its very slow.You can use COLORREF CImage::GetPixel(int x,int y) it returns RGB of pixels on the loop you can use of it for first gif and second gif for check COLORREF.

Hi Hamid, Thanks for your reply.But I failed to get it. In your free time plz send me the code.I think no of lines will be limited to max 10.So won't take more time. Thanks & Regards.

Hamid Taebi

But why you dont use of Codeproject's articles they used of fast way because dont know I saw them on the codeproject or codeguru its better you see here and there.
