Anti-chain (including the station outside the site of any page left a link to the site, is a back chain, the chain to contain the URL of a plain text, where the main is reflected in the Baidu chain above, this may increase your URL of the detonation of the luminosity, to rank helpful.

has a Lab color mode. L indicates the Luminosity, a indicates the intensity from the ocean red to the green, and B indicates the intensity from the yellow to the blue. 　　 Here, the most important thing is brightness (also called brightness). When optimizing an image, we usually compress the color channel, but try to keep the highlighted brightness channel as much as possible, because people are most sensitive to it. Here, the most important thing i

Light Sensor Demo 1Having told a whole bunch of theories, the following example shows the use of a light sensor. Why fully show the usage of light sense, I This example is very easy to write, just write the use of light sense necessary code, and then use a few TextView to display the value of light changes to the user interface. Allows the user to see changes in luminosity at any time.Below are Activity 's Code :Java code: public class Lightdemoac

Creative image magnifiers implemented by pure css3 and css3 creative magnifiers Today I want to share with you a special image magnifier effect with pure css3. Five small pictures are displayed on the page. When you move the cursor over the image, the current image is displayed as a gray background image. The results are very good.

very simple, a simple idea: After switching the space view, first the original cabinet hidden, and then in the same place according to space and equipment situation to create a number of different cubes to list. The color of the cube is adjusted according to the height of the cube. In order to increase the visual effect, you can pay attention to the cubic block not exactly close together, you can leave a little space to increase the three-dimensional sense; free squares set a certain degree of

be used in large quantities to make up for the above shortcomings. Here are some examples to introduce the application of the "layer adjustment method" in the work. Case 1: add contrast Clip image 1. copy this file (menu Image> Duplicate) and name it "Lab Image". in the new file, convert the Color to the Lab Color (Image> Mode> Lab Color ); 2. select the Lightness channel of the file, select all images of the channel [Ctrl A], and copy [Ctrl C] to return to the start work file, paste [Ctrl V]

is the lowest in the color material. The low luminosity of purple gives a dull, mysterious feeling. 1, in the purple red in the composition of more, its consciousness has a sense of repression, threat. 2, in the purple to add a small amount of black, its feeling tends to dull, sad, horror. 3, adding white in the purple, can make the purple dull character disappear, become elegant, delicate, and full of feminine charm. Six, white color sense of light,

the blue character. A) If there is more yellow in orange, its character tends to be sweet, bright and fragrant. b) mixed with a small amount of white in orange, the perception of orange tends to become agitated and powerless. Four, Green is a yellow and blue two components of the color. In green, the yellow sense of expansion and the blue contraction of the sense of moderation, the yellow warmth and blue color to counteract the cold. This makes the green character the most peaceful and stabl

clear color, dark color, pure color, turbid colors named. The relationship between Hue and hue is consistent with the structure of the three-element relationship of the color system, and the axis of light and shade is composed of different luminance levels.Near the light and dark axis of the color group, is a low-purity turbid color tone, LTG color Group, G color Group.Away from the central axis of the color group, is a high-purity V-color, B-color group, near the light and dark axis of the col

-section and the top surface. This representation may be considered to be a more accurate mathematical model of the HSV color space, but the number of levels of saturation and hue that can be distinguished in practice decreases as the luminosity approaches black. In addition, the computer typically uses a finite precision range to store the RGB values, which constrains the precision, coupled with the limitations of human color perception, making the c
