The device screen may have lower pixel resolution than the image rendered in previous step.

Before the image can be displayed, it must be downsampled (resized) to lower pixel resolution.

Physical Pixels

At the beginning, coordinates of all drawings are specified in

Points are abstract units, they only make sense in this mathematical coordinate space.

Points

Point-based drawings are rendered into pixels. This process is known as rasterization.

Point coordinates are multiplied by scale factor to get pixel coordinates. Higher scale factors result in higher level of detail.

Rendered Pixels

Finally, computed pixels are displayed on the physical screen.

The PPI number tells you how many pixels fit into one inch and thus how large the pixels appear in the real world.
