Pixel Pixel Basics:Pixels are the basis of a page layout. A pixel is the smallest area in which a computer can display a particular color. When the device is the same size but the pixels become denser, the screen can display a more detailed transition and the site looks more crisp.Px:pixel, pixels, the smallest unit displayed on the screen for web design, intuitive and convenient;Pt:point, is a standard len

Background Developing mobile H5 Pages Face different resolution of the phone Face different screen size of the phone Visual manuscriptBefore the front-end development, the visual mm will give us a PSD file, called the visual manuscript.For mobile development, in order to achieve the effect of high-definition pages, visual Draft specifications will often follow the following two points:1) First, choose a phone's screen width high as a benchmark (formerly IPhone4 320x480, now

Mobile Web development has been around for more than a year, during which some confusing things have been encountered. Like what: We often use in the viewport exactly what meaning, here device-width and we use JS to get to the screen width of the difference and the connection is what, why remove the Why a lot of resolution of the screen width is not large, screen resolution and the use of JS to get to the screen width of the difference and contact is what? And so on, a series

With the ellipse selection tool, set to a fixed size, height and width of 24 pixels. Click anywhere on the canvas and click in the selection box to drag and place the upper-left corner of the canvas.

of the three-dimensional difference. Having said so much, you may have vaguely sensed that it is not an easy thing to show the ideal effect. Yes, there are many challenges waiting for us, such as light and reflection, highlights and glare, and shadows. In the authoring process, we will try to develop Photoshop features, channels, filters, layer effects and various image adjustment tools, as well as layer blending mode. One thing to know is that there are many different ways to achieve the same

Histogram is an important basic tool in digital image processing, before we discuss various spatial image processing, we must first understand the concept of histogram and its meaning. The histogram provides the statistical information of the image and provides a foreshadowing for understanding the connotation of various spatial enhancement techniques. In addition, histogram manipulation can also be used directly for image enhancement. At present, most digital cameras have the functio

Resolution. If images are an important part of your web page, you need to pay close attention to the scaling in different resolutions, because image scaling may cause blurred and pixel problems.To provide the best visual effects at all resolutions, you need to control the scaling by providing the viewport metadata of the target resolution of your page, CSS or Javascript is used to provide different images for different resolutions.The rest of this document describes how to consider these effect

Mobile web development-view and web development view This article mainly records the classification of mobile terminal video ports and other knowledge. Before starting, let's take a look at a typical example: The above code is believed to be frequently written during mobile development. It studies two things: meta-view and width-based media queries. Generally, we call the above Code the media query function of CSS3. The media query function can be used to display desktop-level web designs in di

Adding a canvas element to a page produces a rectangular bitmap canvas on the page, and you can use JavaScript to draw a graphic image in real time on the canvas. When drawing a drawing, you need to call the canvas's getcontext function to get the object associated with the canvas for drawing graphics (such as 2D graphics, 3D graphics), and then use this object to invoke different graphical functions to draw the corresponding graphic. The following describes how to draw several common graphics i

I. Principles and procedures for regional growthThe basic idea of regional growth is to assemble pixels with similar properties to form a region. In particular, a seed pixel is used as the starting point for each area that needs to be segmented, and then the pixels surrounding the seed pixels with the same or similar properties as the seed

With large canvas design, the image quality can be avoided in the process of resizing. Select the

Principle Analysis First we briefly describe the principle, we click on the point of the click to get the "color", and then follow the algorithm we choose to fill the color can be. Algorithm 1: Seed fil

First of all, we talk about displacement, displacement filter used relatively little, in fact, no matter what tool, its existence, there must be a reason, just depending on whether we will use. Here, we will explain the operation of displacement in detail. The position of the offset filter is the filter--the other--displacement. Displacement maybe we don't use it very often, but, responsibly, displacement is quite powerful, especially for making some seamless design, with five stars. Next, le

, you have to specify a number of pixels after a W (for example, W). To better understand this example, let's look at an effect from the SXC.HV website-"Autumn in Moscow". The size after compression is 1368 x 700, the optimized volume is 389kb. So far, the advantage we've been discussing is to let users download an image that is larger than the device when using their smartphone, so can his device be displayed? Also, keep in mind that the mobile conne

added (with some pixels specified by the user as the target), the effect will be more perfect: (3) Its border matting technology makes the target's boundary more natural and perfect: Of course, it is also imperfect. First, there is no algorithm that can be universally applied. It is no exception. if the background is complex or the background and the target are similar, the split is not very good; second, the speed is a little slow. Of course, there

Note: The digital photos we have taken are generally not of the standard size. The images taken with a digital camera are generally set at the resolution of the computer screen, therefore, the ratio is basically 4: 3, and the size ratio of the standard photo is different. For example, the ratio of the 5-inch photo is 10: 7, and the size of the 6-inch photo is 3: 2, if you
