![]() ![]() The compressibility issue is one of the major problems with bitmap images. ![]() The Drawbacks of using Bitmap Images in your Design This makes them easy to upload and download, so they're very suitable for design projects. All other image file formats use some kind of compression algorithm to reduce the file size so they can be sent via the Internet. ![]() Of all these types, the BMP file format is the only one that cannot be compressed, and it is exclusive to Windows systems. This metadata is very important in many use cases. Other popular formats are RAW and EXIF, which contain not only the information about the image and how to render it but also tells us about the capture device (usually a camera), what settings were used, etc. that are primarily used for web transfers. The most common and widely used formats are JPG, GIF, TIFF, PSD, PNG, etc. The BMP file format is just one of many file formats for bitmaps or raster graphics. What are some Common Formats for Bitmap Images? This can cause a lot of confusion but, for the most part, raster graphics are usually referred to as bitmaps and vice-versa. However, a pixelmap is a map of how individual pixels should be assigned their colors. When it's a bitmap, then using either term is correct. A raster image can either be a pixelmap or a bitmap. How are Bitmap Images different from Raster Graphics?Īlthough a lot of designers use the term raster to refer to bitmap images, it's not always the same thing. bmp file - the data that tells the rendering part of the software how many squares there are and the color of each individual square. The map is sometimes referred to as a key that tells you which color is assigned to each of the thousands of squares on a typical bitmap image. The color is defined by the data for that square on the bitmap. We saw the concept of a map representing the color of each individual square in a bitmap image. Despite this drawback, bitmap images are extremely useful when designing interfaces and print materials. If they are, you will see an effect called pixelation, which is basically the phenomenon where you can see the individual squares rather than a smooth finish. The problem with bitmaps or even raster images is that they cannot be enlarged to a great degree. Now that we've covered the basics of what's a bitmap and how it is stored and used, let's go a little deeper. ![]() This is an important difference for designers to be aware of. In turn, these two image file formats are different from vector images. Of note is the fact that a bitmap image is sometimes also called a raster image, but it is not exactly the same. This bitmap file can be inserted into a document or a design when required. This image is stored in the form of the BMP file format, which has the extension. When a group of these squares or bits is given a coordinated color according to a fixed reference 'map', it displayed a color image, which we call a bitmap or a bitmap image. However, it can get confusing because the bits in a bitmap are sometimes called pixels! What is a Bitmap File? Pixels cannot be stretched or shrunk, obviously, because they are physical units on the other hand, bits or squares that make up a bitmap can be enlarged or shrunken, which makes the image larger or smaller, as the case may be. This square is not the same as a pixel, which is essentially a display unit on electronic screens. How to Use Bitmaps Effectively in your DesignsĪ bitmap is essentially a group of squares on a screen, with each square being assigned a particular color. ![]()
