Cross-browser gray scale solution

The implementation of grayscale initially included the exclusive attribute filter Implementation launched by ie6. Later, w3c implemented the standard filter in css3, but the implementation degree of different browsers was different, therefore, at this stage, we must explore a browser-compatible solution.1. the IE private filter method starts with IE4. IE introduces a private filter to achieve transparency, blur, shadow, light-emitting, and other effects. Of course, it can also achieve

The principle and realization of gray scale of image

First, the basic principle of image gray processing The process of transforming color image into grayscale image becomes gray processing of image. The color of each pixel in the color image is determined by the R, G, b three components, and each component has a value of 255, so that a pixel can have a range of more than 16 million (255*255*255) colors. And the gray

Xubuntu11.04 has a default topic named "gray pigeon ".

With the release of the second beta version of 11.04 (December February 3), XUbuntu will use a new default topic-gray pigeon. Although the theme was inspired by the famous Elementary theme, there are many differences between them. : The border of the form still looks like Elementary, but it will change as it is updated continuously. In addition, many elements need to be combined and upgraded, such as the label style, the selected background color, and

Gray Code generates all subsets of the Set in order

Introduction Gray code, a coding scheme proposed by Frank Gray, a scientist at Bell's laboratory decades ago, was mainly used to transmit signals to prevent errors. In addition to applications in communication and hardware design, Gray code is also widely used in computer-related science, such as generating all subsets of a set in order.

Convert from RGB color to gray color algorithm __ algorithm

First, the basisFor color to grayscale, there is a well-known psychological formula: Gray = r*0.299 + g*0.587 + b*0.114 Second, integer algorithm In practical application, we want to avoid low speed floating-point operation, so we need integer algorithm.Note that the coefficients are all 3-bit precision, we can scale them 1000 times times to implement the integer arithmetic: Gray = (r*299 + g*587 + b*114 +
