0CH ~ 0DH Horizontal resolution. Ignored.

0EH ~ 0FH Vertical resolution. Ignored.

10H ~ 3FH All 0s

40H 0

41H Plane no., this should be 1.

42H ~ 43H Bytes per raster line

44H ~ 45H 0

46H ~ 47H Horizontal pixel count - 1

48H ~ 49H Vertical pixel count - 1

4AH ~ 7FH All 0

1 at pattern byte stands for white pixel and 0 for black pixel. If the width in pixels is not

a multiple of 8, the bits of “1”must be filled at the end of each row to form an integral

part of bytes.

Note: The alignment of word or long word for PCX file is at Intel format. That is the

most significant bytes is located at highest location and least significant byte is located

at lowest location.

Raster Data

There are two types of raster data.

 CC, pattern0

 pattern1

The control byte must be greater than C0H and pattern1 is less than C0H.

rep=CC & 3FH

rep represents the repeat count of pattern0 after expansion. For example, a raster line

data,

3AH, C0H, C1H, 41H, 41H, 41H, 41H, 41H

After compression, they become

3AH, C1H, C0H, C1H, C1H, C5H, 41H

1 2 ... 29 30 31 32 33 34 35 36 37 38 39 40 41
