PES (Brother) Design format
Explanation of Abbreviations :
|
= hexadecimal = decimal = Most significant Bit = Least significant Bit = Value varies or unknown |
uses PEC code block stored in PES file for decoding
also works with PES type 2 files
depending on type of stitch, each stitch has two to four bytes !
File structure :
| Adress : | Variable name : | Explanation : |
| HEX 0008 - 0010 | pecstart | 3 Bytes, pointing to beginning of PEC codeblock stored in PES file, LSB first |
| pecstart + 49 | No. of colors in file | |
| pecstart + 515 | graphic | 3 Bytes pointing to beginning of pixel graphic, LSB first |
| pecstart + 521 | 2 Bytes, x-size of design, LSB first | |
| pecstart + 523 | 2 Bytes, y-size of design, LSB first | |
| pecstart + 533 | Beginning of stitch data | |
| pecstart + graphic + 512 | End of stitch data | |
| pecstart + graphic + 513 | 228 Byte pixel graphic, each bit = one pixel, drawn from top left to bottom right |
Examples :
| Byte values: | No. of Bytes: | Explanation |
| kx=254, ky=176, NN |
3 | Color change, Byte following ky gives color No. Stitch data (2-4
Bytes) follows
|
| 128 <= kx <= 254, ky |
2 | Jump stitch, lower four bytes (nibble) of kx is multiplication factor for jump stitch ky, direction of jump is determined as follows: |
| (kx and 15) <= 7 | jump in positive direction. length = ky + (kx and 15) x 256 | |
| (kx and 15) >=8 | jump in negative direction. length = (ky-256) + ((kx and 15)-15) x 256
|
|
| kx,ky | 2 | Regular stitch data 0 <= kx <= 63 : positive 64 <= kx <= 127 : negative, kx=kx-128
0 <= ky <= 63 : positive |
| kx = 255, ky = 0 |
2 | End of stitch data |
