screen area . So, for example, we say that a cell phone is 3.2 feet, that is, the diagonal length of its viewable area is: 3.2*2.54 = 8.128cm.Resolution : It refers to the number of pixels in the vertical and horizontal direction of the screen. For example, the resolution is: 480*320, that is to say: Horizontal direction (width) has 320 pixels. The vertical direction (high) has 480 pixel points.dpi: pixel density, or dots per inch, refers to the number of pixels per inch. such as 160dpi refers

traversal. How long does this function take? This function has a total of 2172 elements, which takes 21720 ms, that is, 21 seconds. Obviously, IE must have reported that the script has been executed for too long. Knowing the cause of low efficiency, we need to solve it fundamentally. Naturally, we need to find ways to merge loops. At first glance, follow the numbers in the notes in the above Code, at least the following points can be merged: 3 and 4 can be combined into a loop, from 120 + 60 +

. The dynamic image Expert Group (mPEG), when defining the SIF (source input format) format standard, has referred to the CIF format standard defined by the International Telecommunication Union (ITU, therefore, the SIF standard format is almost the same as the CIF standard format. The difference between the two is that the SIF format is 525 × 352 @ 29.97fps in NTSC standard (240-line, in the PAL/SECAM standard (625-line), it is 352 × 288 @ 25fps, whi

offset. offset is relative to the original memory address, one memory address + offset = another memory address, if two memory addresses are 65560 and 65800 respectively, the calculation is 65800-65560 = 240. Here, the 240 is the offset, because it is not a memory address that directly points to a memory address, it needs to be added with one memory to get another memory address, for example, 65560 +
