Bmp to hex file

There are well 54 bytes before the first byte 00 of the pixels. The second part, the bitmapinfoheader about the image , makes 40 bytes. It contains informations about the size and the color format of the picture. Indeed, there are 5 lines containing each 5 pixels and a byte 00 at the end of lines. If this value is in zero, all the colors are required.

The third part contains the RGB colors values of all the pixels constituing the picture. Device Independent Bitmaps act as an aid to exchanging bitmaps between devices and applications. Due to the continuous evolution of this file format, the information contained in the headers can be different as per the version of Bitmap. A single bitmap file consists of fixed as well as variable-size structures in a specific sequence.

The File header is not part of this data structure. The color can also consist of bit entries that constitute indexes to the curently referenced palette instead of explicit RGB color definitions. Lets have a look at some of these in detail, especially the headers. A Bitmap File Header is similar to other file headers used to identify the file. All integer values are stored in little-endian format. The detailed information about the image is represented by this header.

Based on this information, application will be determined that will be used to display the image on the screen. All such headers contain a DWORD bit field, specifying their size, so that an application can easily determine the header used int he image.
