Techopedia explains Bitmap (BMP) 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. While it may be easy to scale down an image without loss of clarity, it is not easy to enlarge the image without the image becoming pixelated. (Inherited from BitmapSource) PixelHeight: Gets the height of the bitmap in pixels. Bitmap, method by which a display space (such as a graphics image file) is defined, including the colour of each of its pixels (or bits).

The bitmap provides a relatively easy way to keep track of memory as the size of the bitmap is only dependent on the size of the memory and the size of the units. Therefore, most images you see on the web are compressed bitmaps. When you create a bitmap image (not to be confused with the Windows BMP file format) you are creating a sharp, press-ready image, but with severe restrictions. A Bitmap is a type of graphic that consists of small elements called pixels. To display a bit-mapped image on a monitor or to print it on a printer, the computer translates the bit map into pixels (for display screens) or ink dots (for printers). Qu’est-ce qu’une image Bitmap? An image that clarifies the use of bitmap is as follows − The bitmap given in the image writes 1 for the occupied memory unit and 0 for the unoccupied memory unit. Together, these dots can be used to represent any type of rectangular picture. Bitmap definition: A bitmap is a type of graphics file on a computer. In a standard bitmap image, each dot can be assigned a different color. Each format uses a different type of compression, but they all represent an image as a grid of pixels. Short for "Bitmap." A bitmap (or raster graphic) is a digital image composed of a matrix of dots. This simple, universal image format can be recognized on nearly all platforms, but is not very efficient, especially for large images. Also known as a raster image. The BMP file format, also known as bitmap image file, device independent bitmap (DIB) file format and bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on … * A raster image can be either of the above, depending on how complicated the encoded data is. Elle supporte mal les opérations de redimensionnement qui se traduisent par une perte d'information.

Image matricielle formée de plusieurs pixels (image bitmap) ou points (image imprimée) La Définition pour une image matricielle est : " La quantité de pixels ou de points la composant ". The pixels hold some color and when they are arranged together, they form an image. typically JPEGs and GIFs. Bitmaps are not only more common in everyday life but are easier to use. 1 : an array of binary data representing a bitmapped image or display also : a file containing such data. 2 : a bitmapped image or display.
