Size Description L Size of «Paint Data Section» (including this long) L Offset within «Paint Data Section» of pixel data. Always 28 00 00 00 ? L X Size of picture in dots L Y Size of picture in dots «Length» XSize of the picture in twips. 00 00 00 00 means unspecified. «Length» Y Size of the picture in twips. 00 00 00 00 means unspecified. L Number of bits in a dot. Usually 02 00 00 00 L 00 00 00 00 for greyscale pictures, 01 00 00 00 for colour (?) L Always 00 00 00 00 ? L Encoding (see table below) L (CA) Always FF FF FF FF ? L (CA) Always 44 00 00 00 ? Pixel dataThe two longs marked (CA) are only found in a «Clip Art File». Their use is unknown. They are not included in the size of the section (first long) and the offset of the pixel data(second long): you should add 8 to both of them.There are several ways an image may be encoded: Vlaue Description 00 00 00 00 Plain data 01 00 00 00 8-bit RLE encoding 02 00 00 00 12-bit RLE encoding 03 00 00 00 16-bit RLE encoding 04 00 00 00 24-bit RLE encodingThough all lines have the same length, this length can be a little larger than the picture X size. The remaining padding should be discarded. The length of a line is always a whole number of bytes (after RLEdecoding).8-bit RLE encoding consists of sequences of marker bytes with data bytes. A marker byte of 00 to 7F means that the next byte should be repeated that many times and once more. A marker byte of 80 to FF means that (100-marker) bytes of data follow.12-bit RLE encoding consists of words. The 4 most significant bits hold the number of repetitions minus 1 of the 12 least significant bits.After RLE decoding (or right at the start if this was plain data), you are left with a series of bytes. Depending on the number of bits per pixel, you can get any number of colours. Least significant bits are leftmost pixels, and for colour pictures, blue is usually least significant, green is in the middle, and red is most significant.If the number of bits per pixel equals 2, each byte encodes four pixels. A pixel is two bits wide, and can range from black to invisible: Value Color 0 Black 1 Dark grey 2 Light grey 3 InvisibleIf the number of bits per pixel equals 4, a palette is used for colour images as follows: Value RGB Color 0 00 00 00 Black 1 55 55 55 Dark grey 2 80 00 00 Dark red 3 80 80 00 Dark yellow 4 00 80 00 Dark green 5 FF 00 00 Red 6 00 FF 00 Green 7 FF FF 00 Yellow 8 FF 00 FF Magenta 9 00 FF 00 Blue A 00 FF FF Cyan B 80 00 80 Dark magenta C 00 00 80 Dark blue D 00 80 80 Dark magenta E AA AA AA Light grey F FF FF FF WhitewA 8-bit colour palette as below has been found: Value RGB  00 00 00 00 01 33 00 00 02 66 00 00 03 99 00 00 04 CC 00 00 05 FF 00 00 06 00 33 00 07 33 33 00 08 66 33 00 09 99 33 00 0A CC 33 00 0B FF 33 00 0C 00 66 00 0D 33 66 00 0E 66 66 00 0F 99 66 00 10 CC 66 00 11 FF 66 00 12 00 99 00 13 33 99 00 14 66 99 00 15 99 99 00 16 CC 99 00 17 FF 99 00 18 00 CC 00 19 33 CC 00 1A 66 CC 00 1B 99 CC 00 1C CC CC 00 1D FF CC 00 1E 00 FF 00 1F 33 FF 00 20 66 FF 00 21 99 FF 00 22 CC FF 00 23 FF FF 00 24 00 00 33 25 33 00 33 26 66 00 33 27 99 00 33 28 CC 00 33 29 FF 00 33 2A 00 33 33 2B 33 33 33 2C 66 33 33 2D 99 33 33 2E CC 33 33 2F FF 33 33 30 00 66 33 31 33 66 33 32 66 66 33 33 99 66 33 34 CC 66 33 35 FF 66 33 36 00 99 33 37 33 99 33 38 66 99 33 39 99 99 33 3A CC 99 33 3B FF 99 33 3C 00 CC 33 3D 33 CC 33 3E 66 CC 33 3F 99 CC 33 40 CC CC 33 41 FF CC 33 42 00 FF 33 43 33 FF 33 44 66 FF 33 45 99 FF 33 46 CC FF 33 47 FF FF 33 48 00 00 66 49 33 00 66 4A 66 00 66 4B 99 00 66 4C CC 00 66 4D FF 00 66 4E 00 33 66 4F 33 33 66 50 66 33 66 51 99 33 66 52 CC 33 66 53 FF 33 66 54 00 66 66 55 33 66 66 56 66 66 66 57 99 66 66 58 CC 66 66 59 FF 66 66 5A 00 99 66 5B 33 99 66 5C 66 99 66 5D 99 99 66 5E CC 99 66 5F FF 99 66 60 00 CC 66 61 33 CC 66 62 66 CC 66 63 99 CC 66 64 CC CC 66 65 FF CC 66 66 00 FF 66 67 33 FF 66 68 66 FF 66 69 99 FF 66 6A CC FF 66 6B FF FF 66 6C 11 11 11 6D 22 22 22 6E 44 44 44 6F 55 55 55 70 77 77 77 71 11 00 00 72 22 00 00 73 44 00 00 74 55 00 00 75 77 00 00 76 00 11 00 77 00 22 00 78 00 44 00 79 00 55 00 7A 00 77 00 7B 00 00 11 7C 00 00 22 7D 00 00 44 7E 00 00 55 7F 00 00 77 80 00 00 88 81 00 00 AA 82 00 00 BB 83 00 00 DD 84 00 00 EE 85 00 88 00 86 00 AA 00 87 00 BB 00 88 00 DD 00 89 00 EE 00 8A 88 00 00 8B AA 00 00 8C BB 00 00 8D DD 00 00 8E EE 00 00 8F 88 88 88 90 AA AA AA 91 BB BB BB 92 DD DD DD 93 EE EE EE 94 00 00 99 95 33 00 99 96 66 00 99 97 99 00 99 98 CC 00 99 99 FF 00 99 9A 00 33 99 9B 33 33 99 9C 66 33 99 9D 99 33 99 9E CC 33 99 9F FF 33 99 A0 00 66 99 A1 33 66 99 A2 66 66 99 A3 99 66 99 A4 CC 66 99 A5 FF 66 99 A6 00 99 99 A7 33 99 99 A8 66 99 99 A9 99 99 99 AA CC 99 99 AB FF 99 99 AC 00 CC 99 AD 33 CC 99 AE 66 CC 99 AF 99 CC 99 B0 CC CC 99 B1 FF CC 99 B2 00 FF 99 B3 33 FF 99 B4 66 FF 99 B5 99 FF 99 B6 CC FF 99 B7 FF FF 99 B8 00 00 CC B9 33 00 CC BA 66 00 CC BB 99 00 CC BC CC 00 CC BD FF 00 CC BE 00 33 CC BF 33 33 CC C0 66 33 CC C1 99 33 CC C2 CC 33 CC C3 FF 33 CC C4 00 66 CC C5 33 66 CC C6 66 66 CC C7 99 66 CC C8 CC 66 CC C9 FF 66 CC CA 00 99 CC CB 33 99 CC CC 66 99 CC CD 99 99 CC CE CC 99 CC CF FF 99 CC D0 00 CC CC D1 33 CC CC D2 66 CC CC D3 99 CC CC D4 CC CC CC D5 FF CC CC D6 00 FF CC D7 33 FF CC D8 66 FF CC D9 99 FF CC DA CC FF CC DB FF FF CC DC 00 00 FF DD 33 00 FF DE 66 00 FF DF 99 00 FF E0 CC 00 FF E1 FF 00 FF E2 00 33 FF E3 33 33 FF E4 66 33 FF E5 99 33 FF E6 CC 33 FF E7 FF 33 FF E8 00 66 FF E9 33 66 FF EA 66 66 FF EB 99 66 FF EC CC 66 FF ED FF 66 FF EE 00 99 FF EF 33 99 FF F0 66 99 FF F1 99 99 FF F2 CC 99 FF F3 FF 99 FF F4 00 CC FF F5 33 CC FF F6 66 CC FF F7 99 CC FF F8 CC CC FF F9 FF CC FF FA 00 FF FF FB 33 FF FF FC 66 FF FF FD 99 FF FF FE CC FF FF FF FF FF FFð " Courier New "Times New Roman  " Courier Newð"Times New Roman:1T8LII2D  æ0!"""Û÷ŒSŠ Z0
