Hello enhzflep, The input image itself is 8 bit gray scale image and if i want to detect edge i need more contrast edges ( i enhanced the image ( Histogram equalization ) but the image still looks weird - even we could not see in our human eye )
Here you can find my enhanced images :

ok , sorry

DWORD dwBytesperline -> i am not sure about this parameter , please explain me.
i am using 8 bit image ( 1400 * 1024 ) - so how much it would come for DWORD dwBytesperline??

Sorry for that..
Its Gerber format. used for Printed circuit board format.

yeah i did ..the problem was leaving Whitespaces after \ ..i directly copied from the code and pasted it ,,

Thanks for the reply ..

Here is the link for grevView ( RS-274x ) source, but i don know how to start and where to start..
is the url given below is right one with source code ??

Thanks i have already downloaded this, but i don't know how to use this on my project ..
via XML Parsing ?
How to do, i am new to these area..

Pixel86 26-Apr-12 1:40am View

its Open Multi-Processing - for Parallel processing instead of thread we can use this..

Pixel86 25-Apr-12 2:26am View

yeah, thanks i will do..

Pixel86 25-Apr-12 1:46am View

yeah i tried; could not able to find the corresponding library files to access this ..

Do you know ???

Hello,

this is the code i am using for loading 8 bit image.
I am using bmpfile.h and .cpp ...

I don know what mistake i have done ,, please someone can help me out from this issue....

Here is the main code ..

int nWidth = 149 ;
int nHeight = 126;

unsigned char * pInputBuffer = new unsigned char[nWidth*nHeight]();
