Screen areaĪ screen area is a rectangular two-dimensional grid of screen pixels with the same color depth.
Pixel sorter github serial number#
For example, it would be a poor choice to include the serial number of the device. While many properties of screens could be used for active fingerprinting, the strings used as labels in particular should be considered carefully to minimize the uniqueness.

"640x480", it could include a distinguishing number, e.g. "external", it could include the dimensions, e.g. It could describe the screen relative to the device, e.g. Note: The label can be an arbitrary string selected by the user agent. Ī connected screen has a label, which is a string that meaningfully describes the screen to a user. Return the result of dividing CSS pixel size by device pixel size.Ī connected screen has an orientation, which is described in.

Let device pixel size be the vertical size of a screen pixel. Let CSS pixel size be the size of a CSS pixel. The computer system hosting the user agent presents information using one or more connected screens.Ī computer system’s connected screens may change while a user agent is running.Ī connected screen's device pixel ratio is the result of this algorithm: Represent the intensity of the (red, green, blue) subpixels of an LCD screen pixel. The 24 bits are separated into 3 groups of 8 bits used to Note: Some popular rendering systems model screen pixels as having a colorĭepth of 24. Reasoning about pixel components (subpixel rendering) is out of scope for this specification.Ī screen pixel's color depth is the number of bits used to represent the color displayed by that pixel. Note: On a liquid-crystal display (LCD), each screen pixel is made up of three components.Įach component is a (red, green, blue) light with variable intensity. Screen pixelĪ screen pixel is the smallest component of a screen that can be programmed directly.
Pixel sorter github windows#
Ĭreativity app shows secondary windows (e.g.x-rays) on a high-resolution grayscale display. įinancial app opens a dashboard of windows across multiple monitors.Slideshow app presents on a projector, shows speaker notes on a laptop screen. Here are some use cases that inform the design:

The aim of this specification is enable better experiences for web application users with multiple screens. This document extends existing Window, Screen, and FullscreenOptions concepts, and offers new ScreenDetails and ScreenDetailed interfaces to place windows and request fullscreen on specific screens. Operating systems generally allow users to connect multiple screens to a single device and arrange them virtually to extend the overall visual workspace.Īs multi-screen devices and applications become a more common and critical part of user experiences, it becomes more important to give developers information and tools to leverage that expanded visual environment. 1.2.5 Placing windows on a specific screen.1.2.4 Showing elements fullscreen on a specific screen.1.2.3 Requesting extended screen information.1.2.2 Detecting the presence of extended screen areas.1.2.1 Detecting when screen properties change.
