The color is expressed in 6-bit 16 notation, such as #ffffff, all F, which indicates a combination of various colors and is white.#000000是什么颜色都没有, that's black.Add the transparency, then add 2 bits of 16 binary such as: #00ffffff, a total of 8 digits 16 decimal numbers. Top two bits: 00 is fully transparent, and FF is completely opaque. The rest is calculated bas

Convert RGB color to 16 bit color [Suitable for beginners with game programming] I need to judge the colorkey when doing 16bit alpha blending. In my game engine, the colorkey is represented by Windows RGB color, in this case, we need to convert the RGB color to a 16-bit color. below is my practice.The RGB color is a DWORD Value, 32bit in the format of 0x00rrggbb. Three colors are obtained through three macr

In VC ++, there are two hexadecimal, 10 hexadecimal, and 16 hexadecimal conversions. Author: lixiaosanDate: 04/14/2006 The following is a legend indicating the function used in the conversion process. Bintodec cstring: Format2 --------------------------> 10 -----------------------------> 162 Dectobin strtoul 1. 2 hexadecimal -----> 10 hexadecimal Cstring bintodec (cstring strbin){Cstring strdec;Long ndec = 0, nlen;Int I, J, K;Nlen = strbin. getlength

hexadecimal to decimalUsing the Int () function, the first argument is the string ' 0Xff ', the second argument is the description, and the string is a number of binary numbers. The result of the conversion is a decimal number.>>> int (' 0xf ', 16)15Binary to Decimal>>> int (' 10100111110 ', 2)1342Octal to Decimal>>> Int (' 17 ', 8)15You can actually see that the int () function is used regardless of the number of decimal numbers that are converted in

layoutStraight to the point, similar implementations believe we all know that the core is the use of padding is relative to the width of the parent element (PS: The content width here relative to the parent element, even if the parent element exists padding, the percentage is relative to the content area, You can do your own experiment to verify).If you want to achieve a 16:9 adaptive scale layout, the core code is as follows:DOCTYPE HTML> Bodysty

The example in this article describes the method by which the jquery implementation converts the obtained color value to the 16 binary form. Share to everyone for your reference. The specific analysis is as follows: You may have noticed that in Google, Firefox and IE8 above the browser, get the color value is RGB form, such as RGB (255,255,0), feel very uncomfortable, or in the actual coding is not convenient to use, this time needs to be converted,

A few days ago, a Linux system needs to be installed because of my hobbies and work needs. I chose fedora 16 (don't ask me why, just feel it ). I think it is not difficult to install a Linux system on a hard disk. I have installed a Linux system before. the following is a summary of some problems that may occur during the personal installation process: 1. Download a grub4dos, decompress it to the C root directory, and copy the grldr to the c root dire
