In the previous articles we learn about the file formats that come under the name of Bitmap images. Today we will learn the advantages and some disadvantages of these type of file format.

Bitmap Advantages

Following are some of the benefits of using the bitmap images:

  • Bitmaps are very easy to create. Take a picture with a digital camera, or scan something in, and you’ve got one.
  • Bitmaps are fairly simple to output, as long as your RIP or printer has sufficient memory.
  • They are easy to come by.
  • They are very cost effective. You can take a picture or scan in a drawing, and easily show it on the Internet or send in an email.
  • A bitmap image uses solid color pixels, which can be identified and recolored easily.
  •  The geographic location of each cell is implied by its position in the cell matrix. Accordingly, other than an origin point, e.g. bottom left corner, no geographic coordinates are stored.

 Bitmap Disadvantages

However bitmap images have some drawbacks too. A few common disadvantages of these format are as follows:

  • The most common and obvious disadvantage of these image format is that they are not upward scalable. You can make a bitmap smaller without to much loss, but you cannot make it larger without loosing quality. If you ever see a bitmap image blown up, you’ll notice it has little individual squares or dots that make up the image. When you see it at its optimal size you don’t notice the individual dots, but if you try to make it bigger, the image become fuzzy, jaggy or pixelated.
  • Another disadvantage of bitmap images is that they require higher resolutions and anti-aliasing for a smooth appearance.
  • The bmp file has been created by microsoft and ibm and is therefor very strictly bound to the architecture of the main hardware platform that both companies support.

That is all about the Bitmaps. The next few article will be dedicated to the second category of images: i-e the vector images.
