This is a paper I have spent a month in my postgraduate studies. It takes only a month to design and write a paper. It can be more than just a few minutes to publish, add, modify, and wait for the paper to be published, I remember writing started in November 2010. I wrote it in December 2010. I made a draft at the end of 2010. I changed it several times in early 2011 and finally published it in May. In November 2010, my tutor said that there were many topics that could be studied on wireless se
, high compression ratio, can be graduated transparent , with almost all the advantages of GIF, the disadvantage is that the color is not as rich as JPG, the same picture volume is slightly larger than JPG. But PNG should be promoted in website design, it is recognized as the most suitable image format for the use of Web pages. Almost all of Google's site's image resources are in PNG format. A 8-bit PNG can completely replace GIF.Another advantage of PNG is that successive approximation displays

Alpha Blending, Chinese translation alpha blendblending is the control of transparency. In the final phase of rasterization. Here for example we put a material for a model, then at a point calculated that the color value is called the source, and the point before the accumulated color value, called the target. GrammarBlend Off does not mixBlend srcfactor dstfactor srcfactor is the source factor, and Dstfactor is the target factorFinal color = (shader calculated point color value * source factor)

Fusion (Coherence) is a viewing mode that allows you to run Windows applications as if they were native applications on your MAC.
Note: The Parallels Desktop virtual machine starts in converged (Coherence) view mode on the first boot.
In converged (Coherence) mode, you can use both Windows and MAC applications without having to manage two separate desktops or reboots. You can even download Windows apps directly from the Mac Dock or Mac desktop. In t
