Vector Logo Design Vs Raster Logo Design

Raster graphics are images that are defined in terms of a generally rectangular grid of pixels, or picture elements. Each pixel is one small square of color, which, when combined with other pixels side by side, merge together to form one solid image to the eye.

Raster formats

There have been a number of formats developed over the years to store raster graphics. Some of the most popular formats are discussed below, each with their advantages and disadvantages.

BMP – Bitmap Graphics (Avoid wherever possible)

Easy to create with the built-in Windows Paint program.

Long history, therefore good, universal support.

No compression means the format is lossless.

Creates huge files since no file compression is used.

No transparency.

GIF – Graphics Interchange Format (Good for the web, on images of less than 256 colors, for example simple geometric shapes eg bullets for lists)

Creates small files as good compression is used.

Universally supported across platforms.

Transparency supported.

Animation supported.

Palette of colors limited to 256 per image.

Transparency is only 1-bit, therefore no translucency.

JPG – Joint Photographic Expert Group (Good for the web, for images like photographs where color depth is important but lossless formats produce large file sizes)

Lossy compression format produces relatively small files.

Universally supported across platforms.

Artifacts visible at high compression rates.

No transparency.

PNG – Portable Network Graphics (Great for the web, but be careful if using transparency.

Both lossy and lossless compression available.

Both 1-bit and full alpha channel transparency available.

Small file sizes produced.

Poor support in some web browsers for full channel transparency.

Compression not as great as lossy formats.

Vector Graphics

Where raster graphics are defined in terms of individual pixels, vector graphics are actually stored as mathematical rules – widths, heights, curves, proportions, ratios. Where raster graphics have a set height and width and look pixelated when stretched beyond these boundaries, vector graphics render themselves to the space given to them, such that they are resolution independent. login in to to view image exemples of raster vs vector.

Vector based logos is not based on pixels any longer. It is based on points set at proportional differences, joined with lines and curves, and filled with a solid black color. When drawing curves in vector graphics programs, a number of points are defined and dragged such a smooth curve is plotted. This curve is independent of dimensions but is saved as in proportions and ratios such that it will scale to any resolution.

Vector artwork can be modified and stretched without havinng to worry about loss of quality, clarity or sharpness. Because of their mathematical origins, Vector Graphics are readable scalable without distortion.

Vector graphics formats

Again, a number of formats exist for storing vector graphics, each with their advantages. It is important to note that, by their very definition, vector graphics are SMALL in comparison to raster graphics when it comes to file size. Since they are not saving information on each and every pixel, but rather rules for rendering, file size is cut immensely. The universally accepted format for vector graphics, especially when it comes to company logos and sending files to print, is EPS – Encapsulated PostScript. PostScript is a format developed by Adobe to describe pages to a printer, plotter, or screen. Rather than standing straight data stores instructions for the makeup of the page. Fonts are stored as individual character vector objects, for example, so they can be printed at as high a resolution as the printer can print. Macromedia's Flash technology is an excellent example of vector graphics working at their finest – whatever the size, vector elements of the flash movie appear crisply anti-aliased, and individual frames can even be printed in high resolution due to the vector-based nature.

A good question. At first glance, vector graphics seem to overcome all the difficulties of raster graphics. They can be resized to any size without loss of quality, and pixelation just does not occur. File size is also greatly reduced. However, each format has an individual purpose. A photograph can not be expressed as a vector graphic because it simply is not vector data. A sunset can not be defined mathematically, at the risk of starting a philosophical argument on the world around us. The real world is not vector-based. The table in front of you has an infinite pixel depth, infinite variations in colors, infinite variations in relief and texture. Vector graphics are reserved for images such as typefaces, lines, curves. Complex vector images can be created but they have been created specifically in vectors. Photographs and complex raster effects like lens flares are defined with pixel-by-pixel lighting and color effects, not with vectors.

Logos for businesses should always be created as a vector. Why? For maximum usage. It's all very well creating a great raster logo with lens flares and bevels and gradients but what happens when it needs to be on a huge banner in a hall? Or, at the other extreme, printed on headed notepaper. Raster effects just are not practical when it comes to corporate identities. With vector-based logos, the image will scale to any size and any application; raster graphics would require re-rendering each time a new size was required, not to mention problems with transparency across print and computer platforms.

iPhone 4 App Allows Customers to Request Free Bumper

Have you noticed your iPhone 4 losing reception when you hold it in a certain way? Specifically, holding the iPhone 4 with your left hand or covering the black lines at the bottom of the phone? Apple has acknowledged their fault in the phone and the following article will help you get your free bumper / case to protect your iPhone 4 screen and prevent reception drop.

The first step in obtaining your free bumper is to decide which route you prefer. The two options are in store (where you will fight the masses) or through the new app that apple graciously created.

The app is found by simply typing "iPhone case" in the app store search bar. Once you discover the iPhone 4 case app, download it and allow it to install. After installing click on the app and follow the simple instructions.

The most unusual / annoying part of the process is the wait that is correlated with all of the cases / bumpers. What I found is that most of the products offered have about a 3-12 week wait. Will apple be paying for all of the dropped calls during that wait time? Obviously not; however on the plus side, the cases they offer are quite nice. They could have just provided the basic case, but instead they decided to allow all customers to access some of the most expensive cases.

The nicest thing with this app is that it allows you to send the case where you would like. This contrasts sharply with the order process for the iPhone 4, which forces you to send the phone to the AT & T billing address. If you are a college student, this forced you to have someone at the billing address ship it over to you.

Whatever your situation, this app is a must do! The app will only be available until September 30, 2010. After this time, you will have to bite the cost of the case.
