WebWe can represent the value 0 to 255 using 8 bits. So each component can be represented using 8 bits. Therefore, we will need 32 bits to represent a pixel. For a 2D image we will have pixels arranged in rows and columns. Origin (starting pixel) of the image is at the coordinate (0,0). So, we can denote a pixel (x,y) as P x,y (A,R,G,B) Webubuntu20-dotnet5-opencv4.5.3: multi-stage build by @shimat in #1322.
