Re: How to access pixels - urgent question

  Hi, 
   
  Try this:
   
  uchar getPixel( IplImage*img, int lin, int col ) {
  return ((uchar*)(img->imageData + img->widthStep*lin))[col] ; 
  }
   
  void setPixel( IplImage*img, int lin, int col, uchar valor ) {
  ((uchar*)(img->imageData + img->widthStep*lin))[col] = valor ;
  }
  
Regards,

  Hi guys.

Im trying to access Pixels of a grayscale image to get a
representantive   value. best of all would be if the value lies
between 0 für black and 255 für white.
Do you have an Idea?
I tried to use iplGetPixel, but that function is only for 3 or 4
channel pictures.

Thanx for xour help!
