In this video, we're going to discuss Image Resolution and PPI (Pixels Per Inch) concepts in Computer Graphics. In the display screen, the number of horizontal and vertical pixels is called Resolution and the Image Resolution is specifically concerned with the total number of pixels (Height * Width of Image). Moreover, the Image Resolution is generally described in PPI (Pixels Per Inch). These two are quite important to understand to learn Computer Graphics. So, let's get started now.
