As an example, a 640 x 480 image requires information to be stored for 307,200 pixels, while a 3072 x 2048 image (from a 6.3 Megapixel digital camera) needs to store information for a whopping 6,291,456 pixels. The larger the image, the more disk space the image file will take up. This means a large file needs a large bitmap. Raster images use bit maps to store information. In some contexts, the term bitmap implies one bit per pixel, while pixmap is used for images with multiple bits per pixel.

It is also called a bit array or bitmap index.The more general term pixmap refers to a map of pixels, where each one may store more than two colors, thus using more than one bit per pixel. An image is made up using a collection of pixels referred to as a bitmap.īitmap : In computer graphics, a bitmap is a mapping from some domain (for example, a range of integers) to bits, that is, values which are zero or one. The selfie that you click with your mobile phone is another example of a raster image. A pixel is simply the smallest addressable element of a picture represented on a screen.Ī majority of pictures that we see on our computer screen are raster images. Pixel : In Computer graphics a pixel, dots, or picture element is a physical point in a picture. vector::push_back() and vector::pop_back() in C++ STL.A Step by Step Guide for Placement Preparation | Set 1.Overview of Data Structures | Set 1 (Linear Data Structures).Top 10 algorithms in Interview Questions.Initialization of static variables in C.Understanding “volatile” qualifier in C | Set 2 (Examples).What are the default values of static variables in C?.
