pixel settings and the best picture size can be printed on the table, according to their own wish to print the size of the photo to choose to use. If you want your digital photos to be printed as a general specification (the current mainstream digital stamping is 5R, or 5x7 inches), then 3 million pixels is enough. Now commonly used digital camera image primes are usually 2 million pixels to 8 million pixels. Select the higher the number of pixels o

suggest you use PS this software, his function is very powerful, use up also very convenient.First of all, we can draw from the simplest lines, such as (22.6-degree slash/30-degree slash/45-degree oblique).Line/Line/ARC). We can then try to draw the underlying graphic such as (equilateral/rectangle/rounded/rounded). Then learn how to do perspective/cone perspectives such as 22.6-degree perspective/45-degree perspective/cylinder. Skills:1, portrait of the general selection of the Pencil tool

he raised a question about how it would affect web developers. I've been delving deeply into the wide-spread performance of mobile across browsers, so to speak, in 99%, Apple will not have any impact on web developers. But the rest of the 1% is more of a sore egg, but I expect Apple to use an intermediate transition pixel layer like Android to solve this problem. (John points out) there is such a layer in Android. First of all, I want to make it clea

(Click here for the original article link) Author: Johannes Kopf (Microsoft Research Institute) and Dani lischinski (Hebrew University) Summary We propose a novel algorithm to export a smooth, resolution-Independent Vector image from a pixel image, which can be scaled up without distortion. Our algorithm completely retains the scaling feature information of the original input pixel image, and generates a sh

resolution and the longitudinal resolution. A smaller number is usually a longitudinal resolution, that is, we generally distinguish between the values used for scanner resolution. In other words, the 600x1200 dpi scanner, we are usually referred to as the DPI. The resolution of the computer monitor is about 72dpi, this value is calculated in this way: to a 15-inch computer monitor For example, the visual area of the horizontal length of about 11.2 inches, if the display mode is 800x600, then

Before I begin, I need to make sure that you read this article to learn how to create digital media works based on pixels, but not just here. At this point you might say that I use this method when I want to create a design that needs to be displayed on a digital device, but when I design a work that needs to be printed, I use the usual setup method.

how to create digital media works based on pixels, but not just here. At this point you might say that I use this method when I want to create a design that needs to be displayed on a digital device, but when I design a work that needs to be printed, I use the usual setup method. Not so, in most cases (in some cases, you don't want to use this method: hand-painted works, AI have more flexible curvature), the best design method is based on pixels (in order to fit two media, based on

Which YCbCr 4:1:1 more commonly used, the meaning is: each point to save a 8bit brightness value (that is, Y value), each 2x2 point to save a Cr and CB value, the image in the naked eye of the feeling will not be too big changes. Therefore, the original use of RGB (R,g,b are 8bit unsigned) model, 4 points need to 8x3=24 bites (the first diagram below). And now only need 8+ (8/4) + (8/4) =12bites, an average of 12bites per point, so that the image of the data compression half.

Let's compare the three scenarios together, see Figure 8, from left to right in Figure 7 in the A, B, C scheme, we see that the middle of the B scheme, although no sawtooth, but the volume is significantly smaller than a, C scheme, and C scheme at the same time with a zero-sawtooth, equal volume sense two advantages.

1 Overview YUV is a color encoding method. It is developed to be compatible with black and white TVs. In Modern Color TV systems, three-channel color cameras or color CCD cameras are usually used to retrieve images, and then the acquired color image signals are divided by color, respectively amplified and corrected to obtain RGB, then, the Brightness Signal y and two color difference signal R-Y (U) and B-Y (v) are obtained through Matrix Transform cir
