To the photographic enthusiasts for detailed analysis to share the Canon 100D camera specific pixel values. Analytical sharing: The Canon 100D effective pixel is 18 million pixels and the total pixel is 18.5 million pixels. Well, the above information is small knitting to all of you to bring the detailed Canon 100D camera

(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

Objective In our impression, Flash is based on a set of vector design software, bitmap is not conducive to scaling, and the location of each point of the bitmap and color must be stored, so the bitmap file will be relatively large. Therefore, the general flash used in almost all vector map resources. So, the bitmap in Flash is really useless? You can take a look at the example I've done: Click here to download the source file Is the effect OK? This is the legendary

Do you remember the 1983 Nintendo famous game "Super Mary," the bearded Italian plumber, and the Japanese Konami company 1987 release of the shooting game, "the soul of the bucket" in the two of the mighty Superior soldiers Bill Rezey and Lance Bien. Believe that these two pixel cartoon image in the year to leave a deep impression, but also let me first know the pixel map.Super Mary Image Microsoft's opera

In the book 3D Mathematical Fundamentals-graphics and game development, we see the concept of pixel-to-width ratio. Of course it's good to understand that pixels are squares, so the pixel-to-width ratio is 1. For pixel aspect ratio details, please refer to msdn:https://msdn.microsoft.com/zh-cn/library/cc294571.aspx, I will parse the meaning of the formula after q

The pixel padding rate refers to the number of pixels that the graphics processing unit renders per second, in mpixel/s (million pixels per second), or gpixel/s (1 billion pixels per second), which is the most common metric used to measure the pixel processing performance of the current display chip. The rendering pipeline is an important part of the display core and is a set of specialized channels in the

Use the text in Flash with a very small font size? Of course, the first time to think of 04 such a classic pixel font (PIXEL font) but with the PIXEL font disadvantage is not no, the first is the need to set a fairly accurate, otherwise the word or to paste (need to be accurate to 0.1 pixel adjustment, very annoying) f

OpenCV Learning (Pixel operation manipuating the Pixels) OpenCV Although there are many types of image processing functions, you can do a variety of common image processing, but there will always be some operations are not, then we need to manipulate the pixels, to achieve the functions we need. Today we will talk about several methods of OpenCV for pixel-level operation, and make a comparison. In OpenCV,

One pixel knowledge 1.1 device pixel (Devices pixel)It is a physical concept, referring to the physical pixels used in the device (physic pixel). This unit is represented by PX, which is a [relative absolute unit] ————That is, on the same device, the physical length (such as inches) represented by each of the 1 device

principle of Google, find some answers on the internet, the following is a simple answer. 1. DPI and PPI what the hell. The DPI (Dots per Inch) is initially used to measure the number of points that are printed without an inch, which means that your printer can hit as many points in an inch. The smaller the DPI value, the less pleasant the picture is. When the concept of the DPI is used on a computer screen, it should be called PPI (Pixels per Inch). Similarly: PPI is the number of

Pixel In English pixel, the abbreviation of image elements (picture element) is the number of points in the unit area that make up the image. Each pixel has a different color value. The more pixels in the unit area, the higher the resolution, the better the effect of the image. Pixels are sometimes referred to as PEL (the abbreviation for picture element). The
