RASTER IMAGE EXAMPLE PROFESSIONAL

If the raster file (photo) is of really high quality, it can be converted and accepted for high-quality printing. Raster images are also converted into graphic files that can be made to print for commercial printing. PNG is another common file format used online. This means you can have your logo overlap with other objects without a white box appearing around the logo. This file format supports raster graphics that allow for a clear background. One of the most common file formats for this is PNG (Portable Network Graphics).

If you are looking for a raster image that does not have a white background, such as for an online logo, then you need to save your file in a format that supports transparency.

Almost all of the images in a Google image search are raster images. In this way, a raster file such as a JPEG can be easily shared with anyone, almost anywhere. The advantage to this being that a JPEG is a type of file format that virtually any device today can open and view. The same for probably any other type of program that has a “Save as JPEG” export feature. One can take a document such as a Word file, and export it out as a JPEG. There are so many different types of raster files, but here are some of the most common ones:Īlmost any type of document can be rasterized. From photos to logos, almost every image on the world wide web is a raster image. Raster images are what you are seeing, by and large, when you are online.

But, if you are a working professional in a number of fields relying on high-resolution raster files, you will want to make sure you are using high-resolution raster images for professional output. This may not be an issue if you are posting online socially such as to share between friends and family. With each save, you can potentially degrade the image quality. If you remember photocopiers and the idea of making a copy of a copy of a copy…well, that’s what’s happening. This can happen each time you re-save a photo back onto itself. This is accomplished by removing data from the file itself to become even smaller in file size. That’s because the JPEG file format generally compresses the image to save file size from getting too large. A raster image is best for photographs and images requiring smooth color transitions.īeware: saving the same JPEG file continuously over itself can degrade the quality of the image. Collectively, these bitmaps form the images in continuous tone graphics, such as photos. Bitmaps are tiny coded squares of color that appear grid-like if you were to view them extremely close up. We’ll talk more in depth about vector images next month.Ī raster image is a type of file format composed of bitmaps. The source of this type of graphic is more than likely coming from a digital device, such as a smartphone or even a DSLR (professional digital camera such as from Canon or Nikon, etc.) Whether the photo is taken on the fly using your cell phone or technically set up in a photographer’s studio, they are both essentially the same file format. In this article, we’ll talk about the most common graphics file format: the raster image.Ī photo is a “graphic” and is the most common file being posted to social media. Even if you only casually post photos to social media such as Facebook or Instagram, you are aware of what a graphic file is. For the vast majority of people posting online, that’s usually a JPEG or JPG file. Chances are you have had to deal with logos or graphics at some point in your career.
