To reveal Middle Eastern type options in the Photoshop interface, do the following:
To create content in Arabic and Hebrew, you can make the right-to-left (RTL) direction the default text direction. However, for documents that include left-to-right (LTR) text, you can now seamlessly switch between the two directions.
When you are working in Arabic or Hebrew, you can select the type of digits you want to use. You can choose between Arabic, Hindi, and Farsi.
By default, in Arabic versions of Photoshop, Hindi digits are auto-selected; in Hebrew versions, Arabic digits are selected. However, you can manually change digit types if necessary:
In Arabic, text is justified by adding Kashidas. Kashidas are added to Arabic characters to lengthen them. Whitespace is not modified. Use automatic Kashida insertion to justify paragraphs of Arabic text.
Select the paragraph, and at the lower-right of the Paragraph panel, choose an option from the Insert Kashidas pop-up menu: None, Short, Medium, Long, or Stylistic.
Note: Kashidas are inserted only in paragraphs with fully justified margins.
To apply Kashidas to a group of characters, select the characters in the document, and then choose Type > Language Options > Kashidas.
With some OpenType fonts, you can automatically apply ligatures to character pairs in Arabic and Hebrew. Ligatures are typographic replacement characters for certain letter pairs.
Discretionary ligatures provide more ornate options that some fonts support.
A font can provide alternative shapes for certain letters, typically for stylistic or calligraphy purposes. In rare cases, justification alternates are used to justify and align paragraphs containing these shapes.
Justification alternates can be turned on at a character level, but only if a font supports this feature. At the bottom of the Character panel, select Justification Alternates.
These Arabic fonts contain justification alternates: Adobe Arabic, Myriad Arabic, and Adobe Naskh.
These Hebrew fonts contain justification alternates: Adobe Hebrew and Myriad Hebrew.
