What is raster to vector conversion? Computers Articles | February 25 Derek Carr Color Rush Jersey , 2010
Raster to Vector (or R2V) is used extensively in commercial and industrial applications to convert technical drawings, maps and other paper graphics from scanned raster files to vector formats. The process starts with a high quality scan.


Scanning



When a paper drawing is scanned, the resulting digital file is a raster file. The large format scanner used to scan paper drawings for raster to vector conversion should be a scanner that is capable of providing a high quality image. Image quality is everything here.?? If two lines are muddied and appear as a single line in the scanned drawing it will be difficult, if not impossible, to know that they should be separated when the scanned raster image is converted to a vector image. Once you have the best scanned raster image possible, rectify the image to make sure it is aligned correctly Howie Long Color Rush Jersey , scaled correctly, and that it measures correctly on all axes points.


Converting



In order to work with a digital file in a CAD (Computer Aided Design) system, the scanned raster file needs to be converted to a vector file by a process called raster to vector conversion or, simply, vectorization. According to Wikipedia, ?vectorization refers to the process of converting raster graphics into vector graphics.? In very simple terms Bo Jackson Color Rush Jersey , this means converting pixels, which are dots of color (raster) like this? . . . . . . . . . . . into lines (vectors) like this __________. It?s important to note that when you enlarge a raster image, the dots or pixels begin to break apart, and you lose the clarity of the image.? (Think about enlarging a photo taken with your digital camera). On the other hand, a vector image can be enlarged indefinitely without loss of integrity, because it is made of lines Antonio Brown Color Rush Jersey , arcs, polygons, etc.



But how exactly to convert from raster to vector?



There are many different conversion methods. There are commercially available raster to vector conversion software packages from companies like GTX, Hitachi, IVector, and Softelec. Some conversion service companies have written their own raster to vector conversion routines. Unfortunately I have found that one raster to vector conversion product does not fit all. It is not uncommon with 100 drawings Hunter Renfrow Color Rush Jersey , that 30% are converted via one (1) method, the next 40% need to converted via a different method, and the remaining are hand redrawn.



Please do not be misled with raster to vector software vendors promising 'automatic raster to vector conversion'. Simply put, it is not true.? These products are tools - and only tools. They all can help in the conversion process, but they are not the cure-alls they claim to be.



Generally, I have found that the most reliable way to get ?CAD Perfect? digital drawings is by using an experienced raster to vector conversion service. Make sure the firm has proven and verifiable capability to provide converted files that can be brought into your AutoCAD Foster Moreau Color Rush Jersey ,? Microstation, or other CAD program that you use. Make sure that the conversion service you choose is able to provide vector files that are easily editable in your PC CAD, CNC, GIS or other program.

Finally, confirm that the raster to vector conversion service that you use provides quality control and a satisfaction guarantee. The work should be guaranteed to be 100% correct, 100% of the time. No exceptions. No excuses.


Is saturated fat good for you? Health Articles | December 29 Isaiah Johnson Color Rush Jersey , 2016

Despite years of shunning fat in favor of carbs and protein, we appear to have reaped zero health benefits. We did not see heart disease risk decrease. We did not see waistlines slim down. 聽Now, in fact, a recent Norwegian study suggests that fat, and again in particular saturated fat, is good for us.2 What? How could the research be so polar opposite to our previous understanding?



Likely by now you’ve heard the debate. Is fat Maxx Crosby Color Rush Jersey , and in particular saturated fat, bad for you or not? In the 80’s and 90’s we made fat the villain and steered our entire country towards a low fat mentality, but in recent years perceptions have evolved. Studies have come out to contradict previous research that found fat harmful to cardiovascular health. Even more recently we found that some studies were in fact manipulated to spin sugar in a more positive light and lay the health blame squarely on fat. Just a few months ago NPR reported that the sugar industry paid scientists to bias their research so that fat appeared to be the main concern in regards to heart health.1 So, what are we to believe?


Studies still go both ways, but we certainly have a growing collection of research to show that fat does not deserve to be treated as an evil part of our diet. Despite years of shunning fat in favor of carbs and protein, we appear to have reaped zero health benefits. We did not see heart disease risk decrease. We did not see waistlines slim down. Increased consumption of Snackwells and low fat lattes did not result in the statistics health experts were hoping for.


Now Trayvon Mullen Color Rush Jersey , in fact, a recent Norwegian study suggests that fat, and again in particular saturated fat, is good for us.2 What? How could the research be so polar opposite to our previous understanding?


In the study, the researchers did not simply take subjects, put them on high fat diets Johnathan Abram Color Rush Jersey , and observe the results, as many previous studies have done. No, they put people on carefully crafted high fat diets that were rich in unprocessed or lowly processed choices, such as butter, cream and cold pressed oils. These were combined with a decent intake of vegetables and whole grains while simultaneously avoiding white fl.
