Microsoft has defined a particular representation of color bitmaps of different color depths, as an aid to exchanging bitmaps between devices and applications with a variety of internal representations. They called these device-independent bitmaps as DIBs, and the file format for them is called DIB file format or BMP file format. According to Microsoft support: A device-independent bitmap (DIB) is a format used to define device-independent bitmaps in vari… Microsoft has defined a particular representation of color bitmaps of different color depths, as an aid to exchanging bitmaps between devices and applications with a variety of internal representations.

WebA bitmap consists of the pixel data for a graphics image and its attributes. There are many standard formats for saving a bitmap to a file. GDI+ supports the following file formats: BMP, GIF, EXIF, JPG, PNG, and TIFF. For more information about supported formats, see Types of Bitmaps. WebBitmaps and vectors As you learned in Week 1, text and colours in computers are stored and transmitted as a series of ones and zeros (binary). This is also true for the images and graphics you see on screen. How an image is encoded depends on whether it is stored as a bitmap or a vector image.
WebVector graphics are stored as a list of attributes. The attributes are used by the computer to create the graphic. Rather than storing the data for each pixel, the computer will generate an object ... WebAll bitmap images are stored in the computer as a rectangular grid of pixels. The resolution of an image refers to the number of pixels in the grid; higher resolutions mean that more details can...
