binary blue color

The C language converts the color BMP bitmap into a Binary Map, bmp bitmap CTF does not have a systematic understanding of the hidden Question of the image. First, we will summarize the composition of the BMP image and deepen our understanding by converting the color image into a binary image. Only the format and code

JavaScript implements the method of color RGB and 16 binary conversion. Share to everyone for your reference. Specific as follows:Color (12,34,56); Color ("#fff") Color ("#defdcd")//color Conversion var-color = function () { if (!

Values begin with a # sign.The first 2 digits represent the transparency of the color, 00~FF, 00 indicates that the color is completely transparent, and FF indicates that the color is completely opaque.The latter 6 digits represent the RGB value of the color. such as: 000000 for Black, ffffff for white, ff0000 for red

In the development of web pages, often need to color settings, and often need to encounter the issue of color conversion, such as: RGB to 16 binary, 16 to RGB, a few days ago in the test, found that the color of the site to convert a class of 16 colors (for example: #000080, # FA08FA) conversion always prompt

Principle: RGB Color According to the calculation of ' grayscale ' formula, can be converted to black and white 2 colors, achieve two value.Business Scenario Application: Depending on the background color, take a black or white color, as the background color of the copy font colorSpecific code: function GetTextColor
