It is very likely that you have dealt with a bitmap image. They are the type of image produced by digital cameras and scanners. People also use them when they are editing or enhancing photos or drawings. These images, although widely used, have several advantages and disadvantages. This includes issues with resizing an image, image quality, and file size.
Bitmap images are made up of small squares that work together to create a recognizable realistic image.
One of the benefits of using a bitmap image is that you can display an image realistically. Bitmap images are made up of pixels, which are basically a dot of color. Properly placing dots of different colors next to each other will create the illusion that one color is mixing with another. Therefore, it is easier to get a more realistic image using this format.
Bitmap images are easy to reduce, but generally cannot be enlarged without pixelating.
The ease with which people can share and edit photos is another advantage of these images. Computer programs ranging from oekaki drawing forums to professional image editing software are available to view, create, and edit these photos. With all the options available, it is possible for just about anyone with access to a computer to share and manipulate some formats of these images. And many people do. Different bitmap image formats are used in website graphics as well as in online art galleries.
A bitmap refers to a type of file format for computer graded images.
One of the drawbacks associated with a bitmap image is that it doesn’t tend to resize very well. While it may be easy to reduce an image without losing clarity, it is not easy to enlarge it without pixelation. Another disadvantage associated with a bitmap is the large file size. An uncompressed image can be very large due to the amount of information required to display all the pixels in multiple colors. This file may take a long time to upload, send or receive.
To combat this, different compressed file formats can be used. The downside to this is that compressing a bitmap file can often lead to artifacts, blurry areas, or incorrectly colored areas that can ruin the details and overall appearance of an image. JPEG (.jpg or .jpeg) and CompuServe Graphics Interface (.gif) are compressed bitmap file types. Depending on the image you have, you may choose to use one of these file types. The JPEG file type can work on a very large and detailed file, like a photograph, but a GIF might be more suitable for graphics, text, or animations.
Bitmap images can be produced by a digital camera.
