best dpi for fps

WebApp development in the early days, will encounter the PC-side development of the page in the mobile display too big problem, here need to add META tags in the HTML head to control the zoomHere are specific instructions for this tag:Viewport Syntax Introduction:The content contains several properties:height = [Pixel_value | Device-height] ,width = [Pixel_value | device-width],Initial-scale = Float_value,Minimum-scale = Float_value,Maximum-scale = Float_value,user-scalable = [yes | no],target-d

The dimensions and sizes must be distinguished by the following units: dp, sp, pt, px, mm, in Px: pixel, in the unit of pixel size. In the android UI, this unit is the same as the actual physical screen resolution, and is mainly used to display the definition effect. Dp: Density-independent Pixels (device independent pixel), short for "dp", that is, dip. It is an abstract unit, because the physical screen is large and small, however, dp displays the same size on different physical screens, t

How do I adapt to the various screen sizes of Android smartphones using Qt-developed Android apps?When it comes to screen sizes, from 2.8-inch to 8.9-inch phone screens, it's a little more painful for program apes. The Android project itself has considered this issue, resource files, ldpi/mdpi/hdpi/xhdpi, and so on, the Android framework automatically selects the appropriate icon based on the screen size, so that the application looks the same on different screen sizes.What about the Qt applicat

Camera pictures, pictures on the computer, text in Word, computer screen, mobile screen, camera screen display size Everything's all figured out!First, the picture.xxdpi= points DotX is the actual size of the picture, simple point, we only calculate the height of the picture, for example, took a picture 144x144 72dpi, then its actual height is 144÷72=2 inchesDPI is the dots per inch, after the camera has taken a picture of its DPI is determined (right

. The height is calculated based on the aspect ratio of the device screen. (In fact, the height of the viewport is almost useless and can be ignored) In this way, the width and height of the viewport provided for CSS computing are similar to those of the desktop browser, and the rendering Effect of page computing is almost the same as that of the desktop browser. Page zoom-in does not affect layout viewport, that is, does not affect page rendering. In a mobile browser, when all pages are

undoubtedly possible, but it is not universal... The following is an example: Let's first implement the process of setting the height of the ImageView to make the image display a normal proportion in this specific simulator: The actual pixel size of the above image is: 828*314, the ratio of width to height is about 2.43, and the size of the simulator we use here is 480*800 (unit: px, that is, pixels), that is to say, the width of the pixel is 480, so we need to set the height of this ImageVie

In the past two days, I used swing to write and print data. I found that the JDK document contains a description in units of 1/72 inch. It is troublesome to convert the paper size and screen size. What is 1/72 inch. I found the following information and finally found the conversion formula. Let's record it here :) 72 pixels/inch = 28.346 pixels/centimeter 300 pixels/inch = 118.11 pixels/centimeter 1 CM = 0.3937 inch 1 inch = 2.54 cm Later I found another article, which is fully written.

In this case, we will briefly animate the motion Picture (animation). Just like the cartoon principle, the essence of animation is to use the visual persistence of the human eye, quickly transform the picture, resulting in the illusion of the object in motion. For the Three.js program, the implementation of the animation is also achieved by redrawing the screen several times per second.To measure the screen switching speed, the concept of fps (Frames

First, let us know an unfortunate message: pixels cannot be directly converted into inches or centimeters, and must be converted under DPI!

-scalable=no" />Android 4.0 ~ 4.3As a relatively old version of Android, it has a poor support for the width attribute in meta. In Samsung Note II, for example, its device-width is 360px. If you set the width (hereinafter abbreviated) in viewport vWidth to a value that is less than or equal to 360, it will not have any effect, and a vWidth value greater than 360 will not cause the screen to scale, but a horizontal scroll bar appears.If you want to support Android 4.0 to 4.3, you still have to re
