Getting or Setting Pixels

Getting or Setting PixelsThe Safe (slow)

• Suppose you is working on an image<bgr, Byte>. You can obtain the pixel in the y-th row and x-th column by calling

= img[y, x];  

• Setting the pixel on the y-th row and x-th column are also simple

IMG[y,x= Color;  

The fast

The Image pixels values is stored in the Data property, a 3D array. Use the If you need to iterate through the pixel values of the image.

For example, in an grayscale image (Image<gray, byte>), instead of doing this:

= Imagegray[x, y];  

You would does this:

= Imagegray.  Data0];
