fonts: โค๊ดไพธอนที่ใช้ช่วยทำงาน
Submitted by wd on Mon, 2008-04-21 12:05
Topic:
สรุปรวมจาก python: เขียนโค๊ดคลี่แสต็กฟอนต์ และ python: โค๊ดฟอนต์ย้อนกลับ
รวมเป็นไฟล์เดียว ตั้งชื่อว่า
เวลาใช้งาน จะต้องเขียนสคริปต์ไพธอนเพิ่มสำหรับฟอนต์แต่ละตัว เพื่อมาเรียกใช้ dfont เป็นมอดูล ปรับปรุง
รวมเป็นไฟล์เดียว ตั้งชื่อว่า
dfont.py การทำงานแค่คลี่และเรียงแสต็กใหม่เวลาใช้งาน จะต้องเขียนสคริปต์ไพธอนเพิ่มสำหรับฟอนต์แต่ละตัว เพื่อมาเรียกใช้ dfont เป็นมอดูล ปรับปรุง
- 51-05-06 เพิ่มฟังก์ชั่นการทำ grid fitting ทำให้การเขียนโค๊ดง่ายขึ้น
เช่นต้องการขยับจุด 20 ไป +8 ที่ฟอนต์ขนาด 9, 10 และ 11 ppem
เดิมเขียนโค๊ดเป็น
deltap1 3 20 15 20 31 20 47เปลี่ยนเป็น
f_deltap 20 9+8 20 10+8 20 11+8

"""
This file is only stack render engine.
Usage:
1. Decode from instucted code
./dfont.py -d INST_CODE.txt > PSEUDO_CODE.txt
2. Encode from pseudo_code
./dfont.py -e PSEUDO_CODE.txt > INST_CODE.txt
Implement:
1 Create FONTNAME.py contain code as followed:
1.1 import dfont, sys, os
1.2 cvt_dict = {"NAME": VALUE, ... }
1.3 pseudo_code_dict = {"CHARACTER_NAME": "PSEUDO CODE TRUETYPE INSTRUCTION", ...}
1.4 if __name__ == "__main__":
if sys.argv[1] == "--all":
#$0 --all = ENCODE ALL CHARS
sfd_file = os.path.basename(sys.argv[0]).split('.',1)[0] + '.sfd'
print "Encoding all character in %s" % (sfd_file)
dfont.inst_encode_all( sfd_file, pseudo_code_dict, cvt_dict )
else:
#$0 uni0E01 > x.txt = PRINT INSTRUCTION CODE OF uni0E01 TO x.txt
print '\n'.join(dfont.inst_encode( pseudo_code_dict[sys.argv[1]], cvt_dict ))
2 Encode:
2.1 Process all character, this script will modify FONTNAME.sfd
Usage: ./FONTNAME.py --all
2.2 Encode each character, for example KO_KAI="uni0E01"
Usage: ./FONTNAME.py uni0E01 > INSTRUCTED.TXT
