BMP file format Wikipedia. The BMP file format, also known as bitmap image file or device independent bitmap DIB file format or simply a bitmap, is a raster graphicsimage file format used to store bitmapdigital images, independently of the display device such as a graphics adapter, especially on Microsoft Windows1 and OS22 operating systems. The BMP file format is capable of storing two dimensional digital images both monochrome and color, in various color depths, and optionally with data compression, alpha channels, and color profiles. The Windows Metafile WMF specification covers the BMP file format. Among others wingdi. BMP constants and structures. Device independent bitmaps and the BMP file formateditDiagram 1 The structure of the bitmap image file. 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 or DIBs, and the file format for them is called DIB file format or BMP image file format. According to Microsoft support 4A device independent bitmap DIB is a format used to define device independent bitmaps in various color resolutions. The main purpose of DIBs is to allow bitmaps to be moved from one device to another hence, the device independent part of the name. A DIB is an external format, in contrast to a device dependent bitmap, which appears in the system as a bitmap object created by an application A DIB is normally transported in metafiles usually using the Stretch. DIBits function, BMP files, and the Clipboard CFDIB data format. The following sections discuss the data stored in the BMP file or DIB in detail. This is the standard BMP file format. Some applications create bitmap image files which are not compliant with the Microsoft documentation. Also, not all fields are used a value of 0 will be found in these unused fields. File structureeditThe bitmap image file consists of fixed size structures headers as well as variable size structures appearing in a predetermined sequence. Many different versions of some of these structures can appear in the file, due to the long evolution of this file format. Referring to the diagram 1, the bitmap file is composed of structures in the following order Structure name. Optional. Size. Purpose.

When loaded in memory as non packed DIB, it is located between the color table and Gap. DIBs in memoryeditA bitmap image file loaded into memory becomes a DIB data structure an important component of the Windows GDI API. The in memory DIB data structure is almost the same as the BMP file format, but it does not contain the 1. DIB header. For DIBs loaded in memory, the color table can also consist of 1. RGB color definitions. In all cases, the pixel array must begin at a memory address that is a multiple of 4 bytes. In non packed DIBs loaded in memory, the optional color profile data should be located immediately after the color table and before the gap. When the size of gap. DIB data structure is customarily referred to as packed DIB and can be referred to by a single pointer pointing to the beginning of the DIB header. In all cases, the pixel array must begin at a memory address that is a multiple of 4 bytes. In some cases it may be necessary to adjust the number of entries in the color table in order to force the memory address of the pixel array to a multiple of 4 bytes. For packed DIBs loaded in memory, the optional color profile data should immediately follow the pixel array, as depicted in diag. Packed DIBs are required by Windows clipboard API functions as well as by some Windows patterned brush and resource functions. This block of bytes is at the start of the file and is used to identify the file. A typical application reads this block first to ensure that the file is actually a BMP file and that it is not damaged. The first 2 bytes of the BMP file format are the character B then the character M in ASCII encoding. All of the integer values are stored in little endian format i. Offset hex. Offset dec. Size.

This block of bytes tells the application detailed information about the image, which will be used to display the image on the screen. The block also matches the header used internally by Windows and OS2 and has several different variants. All of them contain a dword 3. The reason that there are different headers is that Microsoft extended the DIB format several times. The new extended headers can be used with some GDI functions instead of the older ones, providing more functionality. Since the GDI supports a function for loading bitmap files, typical Windows applications use that functionality. One consequence of this is that for such applications, the BMP formats that they support match the formats supported by the Windows version being run. See the table below for more information.
