The exact PNG image file format is not new to the web. It in the beginning developed in the mid-90s as a solution to the shortcomings of your traditional GIF image file format. However , because early technique applications offered only spotty support for the PNG’s highly developed features, web designers, developers were limited in its use.
But so what?!? And besides being one letter short of my favorite 72 video game, what makes a free clipart so great? Below, are some reasons why PNGs are the best image format since the Polaroid.
types of See-Through! (Alpha Transparency):
As compared to the GIF, PNG is designed with a far less basic form of transparency. With GIFs, a particular coloration (or colors) is able to be saved as transparent, allowing colors either entirely opaque or transparent. There is no hidden inside.
PNGs have a distinct advantage in this area. The PNG image format supports “semi-transparent pixels, ” meaning a PNG is often saved with a soft drop shadow and floated in excess of any background. It can be used as a watermark on a finished or gradiented background. It can even be smoothly faded out of fully opaque to transparent, revealing the web page ingredients beneath.
Summerour. net features a logo which demonstrates the following function. The homepage layout called for a logo by using a soft drop shadow over a textured background of industrial sketches that regularly change. Using a GIF or JPG would be highly impractical, because every time the image changed, the main logo’s background would need to be edited. A PNG, nevertheless is floated over the image with a faded drop of an, making the task quick, simple and dynamic. PNGs make the look of your page flexible.
They Look Great!
(Lossless Compression ):
Every time a JPEG is saved and compressed, it loses some of the original file’s information and the image quality degrades. The GIF file format offers lossless compression (so the file can be saved and resaved without losing image quality), but it only supports a limited 256 color palette, making it inadequate for full-color photography and other such complex images.
PNG offers the best of both worlds. It displays full color photographic images, like the JPEG, but it also supports a managed color scheme, like the GIF format. While the PNG will typically have a much better file size than the JPEG for photographic images, it does employ a distinct advantage: its compression is lossless, meaning pics never degrade in quality or suffer from “compression artifacting” which affects many JPEG images.
The results are clearer, brighter images that will “pop” on your pages unlike ever in your life.
They’re Self Optimizing! (Gamma Correction ):
Adjusting the actual brightness and contrast of images to look correct using a wide variety of monitors and operating systems is a common problem facing web-designers. This problem is primarily related to different monitor Gamma options.
Gamma is a method monitors use to distribute their luminance evenly across the display. Unfortunately, different operating systems (in unique the Mac and Windows) use different Gamma adjustments. So an image that is color-corrected for the Macintosh operating system may perhaps look too dark on the Windows operating system and conversely.
