This article is a personal blog backup article, the original address:http://validvoid.net/win2d-dpi-dips/This article is intended to explain the difference between physical pixels and device-independent pixels (DIPs, devices independent pixels), and how win2d handles DPI (dots per inch/in dots).WIN2D is designed to be self-aware of the device environment to render the correct visual representation on device
We know that with the support of high DPI, the Windows XP era started, when support for high DPI was relatively simple, but from vista/win7 to now win8/win8.1, Windows ' support for high DPI has changed a lot,Let's briefly introduce the following. If we had reason not to focus on high DPI in the previous XP era, then i

I recently handled a problem about DPI. I think it's interesting to share it with you. First, let's clarify several concepts:
DPI:Dots per inch, the number of points per inch. We often say that the mouse DPI refers to the number of points that move the mouse 1 inch away from the slippery point; print DPI, the number of points that are printed per inch in length
first, the basic concept
Dip:density independent pixels, device independent pixels.
DP: Just Dip
PX: pixels
dpi : dots per inch, which is directly the number of pixels in an inch. A common value of 120,160,240. I am generally referred to as pixel density, short density
density : Direct translation of the words seems to be called density. Common values are 1.5, 1.0. Proportional to the standard

Traditional DPI scaling mechanism
The traditional DPI scaling mechanism is used by Windows XP, and developers are self-checking for potential problems with font scaling.
Pros: Clear Fonts
Cons: Typographical disorders (UI element text box overlay, table text overflow, interface beyond screen edge)
Modern dpi scaling mechanism:
Tongteng Network Shunt, also known as the core network collector, is an important basic equipment for the network monitoring front-end in the network security field. It is an essential equipment for the entire network security! It plays a key role in network security! Currently, the fixed network has been upgraded to 400 GB, supporting different links. The mobile Internet signaling collection traffic has been upgraded to a GB interface, supporting different carriers to separately distribute traf
Explanation of dpi/screen-size on androidAndroid defines four screen-size: small normal large xlarge and six dpi levels: ldpi (low )~ 120 dpimdpi (medium )~ 160 dpihdpi (high )~ 240 dpixhdpi (extra-high )~ 320 dpixxhdpi (extra-high )~ 480 dpixxxhdpi (extra-high )~ 640 dpi defines these levels to better organize resources to adapt to different devices.

Now the consumer electronic devices screen more and more small, but the resolution is increased, such as Surface pro,10.6 inch screen, 1080p Full HD display, will make Windows display text becomes unusually small. This phenomenon is due to the fact that the screen dot pitch is smaller than the standard (about 207.82 dots per inch, the standard is about 96 dots per inch), but the display is more subtle, but the Windows rendering of text is still the default D
The dpi of the mouse is the dots per inch, which is the number of points that the mouse moves on the screen every inch of the pointer. For example, 400DPI mouse, when he moves an inch, the pointer on the screen can move 400 points.
Precision
In fact, the concept of DPI can not be more accurate only to represent the accuracy of the mouse. For example, the dots in dots per inch are not constant

Mouse is a very important computer operation peripherals, in the operation of computer control plays a vital role. DPI is one of the most important parameters in determining the performance parameters of the mouse. Often have some netizens asked small edit mouse how to see the dpi, how to see the mouse optical resolution, and so on, the following Triad Small series will be in detail for everyone to share.
In recent years, with the continuous progress of technology, screen resolution is also constantly improving. has reached the 1920x1080 resolution, which is already a common device configuration, there are higher. However, the default DPI of the Windows system remains at the DPI, which is bad for viewing text under a high-resolution monitor. For this we need to know the
