A bitmap file displays a small dots in a pattern that, when viewed from afar, creates an overall image. A bitmap image is a grid made of rows and columns where a specific cell is given a value that fills it in or leaves it blank, thus creating an image out of the data

It is also called a bit array or bitmap index.Bitmap image downsampled from an Inkscape vectorial imageIn computer graphics, when the domain is a rectangle (indexed by two coordinates) a bitmap gives a way to store a binary image, that is, an image in which each pixel is either black or white (or any two colors).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. Often bitmap is used for this as well. In some contexts, the term bitmap implies one bit per pixel, while pixmap is used for images with multiple bits per pixel.[1][2]A bitmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of bits. Now, along with pixmap, it commonly refers to the similar concept of a spatially mapped array of pixels. Raster images in general may be referred to as bitmaps or pixmaps, whether synthetic or photographic, in files or memory.Many graphical user interfaces use bitmaps in their built-in graphics subsystems;[3] for example, the Microsoft Windows and OS/2 platforms' GDI subsystem, where the specific format used is the Windows and OS/2 bitmap file format, usually named with the file extension of .BMP (or .DIB for device-independent bitmap). Besides BMP, other file formats that store literal bitmaps include InterLeaved Bitmap (ILBM), Portable Bitmap (PBM), X Bitmap (XBM), and Wireless Application Protocol Bitmap (WBMP). Similarly, most other image file formats, such as JPEG, TIFF, PNG, and GIF, also store bitmap images (as opposed to vector graphics), but they are not usually referred to as bitmaps, since they use compressed formats internally. ahm18003231 https://padlet.com/eethansmith/wmi4fyembqr7/wish/285982577 2018-09-26 12:51:32 UTC https://padlet.com/eethansmith/wmi4fyembqr7/wish/285982577 syeddanial786 https://padlet.com/eethansmith/wmi4fyembqr7/wish/285982635 To create a bitmap, an image is broken into the smallest possible units (pixels) and then the color information of each pixel (color depth) is stored in bits that are mapped out in rows and columns. The complexity of a bitmap image can be increased by varying the color intensity of each dot or by increasing the number of rows and columns used to create the image. ]]> 2018-09-26 12:51:39 UTC https://padlet.com/eethansmith/wmi4fyembqr7/wish/285982635 Bitmap images are widely used on digital cameras, smartphones and online. Common bitmap image file types include JPEG, GIF and PNG. Bitmaps are also known as pixelmaps or raster graphics. ahm18003231 https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983451 2018-09-26 12:53:12 UTC https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983451 Typical bit depths are 8, 16, 24, 32 and 48 bits per pixel. ahm18003231 https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983766 2018-09-26 12:53:49 UTC https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983766 syeddanial786 https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983878 Bitmap images are stored as a series of tiny dots called pixels. Each pixel is actually a very small square that is assigned a color, and then arranged in a pattern to form the image. When you zoom in on a bitmap image you can see the individual pixels that make up that image.]]> 2018-09-26 12:54:06 UTC https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983878 123Z123 https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983902 Each pixel is actually a very small square that is assigned to a color ]]> 2018-09-26 12:54:09 UTC https://padlet.com/eethansmith/wmi4fyembqr7/wish/285983902 Vote to remove charles eethansmith https://padlet.com/eethansmith/wmi4fyembqr7/wish/285984532 like yes dislike no
