bmp file header?

meow.

i made a bitmap prog. it was written from the rfc specifications. when i looked at a saved bitmap generated from a paint prog with a hex editor i saw 16 octets that were not in the rfc. 797? forget which rfc. at the begining of the file. it had BM in the first so i assumed that stood for the .bmp file identifyer. i did search many times the rfcs and did not find any file header for the bmp files. meow.

Below is a representation of a bitmap file (each square is one
octet):

----------------------------------------------------------
| 1 | 2 | 3 | 4 | 5 |
| width | width | width | width | length |
----------------------------------------------------------

----------------------------------------------------------
| 6 | 7 | 8 | 9 | 10 |
| length | length | length |x-increment|y-increment|
----------------------------------------------------------

----------------------------------------------------------
| 11 | 12 | 13 | 14 | 15
| data | data | data | data | data...
----------------------------------------------------------

Bitmap formats.

Thank You i gota lota reading to do.

i copied the first 16 octets to the saved file then the rfc stuff format. that i did. that i can do. i was just wondering what the other octets were for after the "BM" and what the header was. what each of the unknown octets were for. meow. some progs let you convert the format just by use "save as" to the new format. about.com had some good stuf for bitmaps info as well. i like reading the vector and raster graphics. will read again thank you.
