אתה יכול פשוט להשתמש בגרסת ME – מזרח תיכון שתומכת בBIDI
אתה צודק, אבל כמו שהיום כבר אין גרסאת חלונות למזרח התיכון, אני חושב שאדובי סתם מתאצלים בקטע הזה.

the way to reverse hebrew text in photoshop is to just click the drop down menu in the Paragraph window and choose “Reset Paragraph”
Thats nice
does the SCRIPT reverse ARABIC ??
Yes, it should. You can try reversing Arabic here http://textreverse.appspot.com/
“Reset Paragraph” didn’t work for me. Is this only on later versions? I have CS2.
CS2!!! Time to upgrade… it just worked for me in CC… many thanks for the help!!
Cheers!
My little script does nearly the same thing, works with connected writing sytems too:

My photoshop just can’t reverse it, I don’t know why.
You saved me 🙂
