PES文件编码

PES格式的绣花文件是Deco、Brother、Babylock等绣花机共用的绣花文件格式。这个格式的优点在于包含了颜色信息，包含了绣花框大小的信息。下面是PES的编码构成
Most numerical values appear to be 16 bit signed ints and are shown as such in this document, unless otherwise noted.
All characters appear to be ascii.

#PES0001 (16 bytes in this section)
1. address of the PEC section start (this is a UInt32)
2. a value of 1 here seems to indicate design data is over 100KB long, or 0 for less than 100KB
3. 1 (the rest of the fields in this section appear to be always the same; they also match the ending fields of the next section)
4. 1
5. -1
6. 0
7. number of characters in the name of the next class (7 for CEmbOne)
CEmbOne (66 bytes in this section)

22. design X offset
23. design Y offset
24. design width
25. design height
26.
27.
28.
29. 1 (the rest of the fields in this section appear to be always the same; they also match the ending fields of the previous section)
30. 1
31. -1
32. 0
33. number of characters in the name of the next class (7 for CSewSeg)
CSewSeg
Start stitch blocks
Block:
(color start indicator) (all color changes have the same value for this field; if the value here is not the same as the first block, it’s not a color change)
(color index)
(number of stitches in this block)
(x value)
(y value)
(x value)
(y value)
(x value)
…
-32765 (block seperator or joiner) (03 80 in hex, 32771 as UInt16)
(block)
(block seperator)
(block)
(block seperator)
…
when you read all the stitches for a block and the next value is not a block seperator, stitch blocks are done (I think)
Start color table:
(color index)
(number of blocks before next color change?)
(color index)
(number of blocks)
…
This block ends with 0 0 (00 00 in hex)
After the color table should be 16716 (LA in char, 4C 41 in hex) which seems to signal the start of the PEC section
