Automate Photoshop to insert text from file - localization

Question

I have a multilanguage website and need automate the process of updating textlayers in psd-files from a csv-source.
I know that there might be glitches in the psp because of changed widths, but anyway it would help a lot to have the text inside the documents.
What are my options?
EDIT:
Murmelschlurmel has a working solution. Here is the link to the Adobe documentation.

The format of the csv-file is not so nice: you need a column for each variable. I would expect a row for each variable.
It works with Umlaut (ä, ö etc)
EDIT 1:
Another solution is to use com to automate Photoshop. Thats nice if you have a couple of templates (buttons) that need changed text. Here is my script in python that might get you startet.
You need to have an excel file with columns:
TemplateFileName, TargetFileName, TargetFormat, Text
(ie template.psd, button1 , gif , NiceButton) .
The first row of the sheet is not used.
The psp template should only have 1 textlayer and can not have layergroups.
import win32com.client
import xlrd
spreadsheet = xlrd.open_workbook("text_buttons.xls")
sheet = spreadsheet.sheet_by_index(0)
psApp = win32com.client.Dispatch("Photoshop.Application")
jpgSaveOptions = win32com.client.Dispatch("Photoshop.JPEGSaveOptions")
jpgSaveOptions.EmbedColorProfile = True
jpgSaveOptions.FormatOptions = 1
jpgSaveOptions.Matte = 1
jpgSaveOptions.Quality = 1
gifSaveOptions = win32com.client.Dispatch("Photoshop.GIFSaveOptions")
for rowIndex in range(sheet.nrows):
if(rowIndex > 0):
template = sheet.row(rowIndex)[0].value
targetFile = sheet.row(rowIndex)[1].value
targetFileFormat = sheet.row(rowIndex)[2].value
textTranslated = sheet.row(rowIndex)[3].value
psApp.Open(r"D:\Design\Produktion\%s" % template )
doc = psApp.Application.ActiveDocument
for layer in doc.Layers:
if (layer.Kind == 2):
layer.TextItem.Contents = textTranslated
if(targetFileFormat == "gif"):
doc.SaveAs(r"D:\Design\Produktion\de\%s" % targetFile, gifSaveOptions, True, 2)
if(targetFileFormat == "jpg"):
doc.SaveAs(r"D:\Design\Produktion\de\%s" % targetFile, jpgSaveOptions, True, 2)

Answer 1

You can use "Data Driven Design" to do this. There is also a concept of data driven design in computer science, but as far as I can see this is not not related to the use of the word in Photoshop.
Here is how to proceed:
Load your image in Photoshop and define your variables with Image > Variable > Define.
Then convert your csv to a format Photoshop can read. I had the best experiences with tab delimted text.
Finally load the text file in Photoshop with Images > Variables > Data Set and let Photoshop save all iterations.
When I tried this first, I found that the Photoshop help file didn't provide enough details. I searched the Internet for photoshop "data set" and found some good tutorials, e.g. this one from digitaltutors.

It might be little bit off too much, but I have used Adobe AlterCast/Grphics server to handle exactly same issue.
Also if its just Text GIF/JPG image, you can use Python+PIL (Python Imaging Library).
Here is a sample code (works on Windows OS with Arial and Osaka fonts installed.)
#!/usr/bin/python
# -*- coding: utf-8 -*-
import ImageFont, ImageDraw, Image
#font = ImageFont.truetype("/usr/share/fonts/bitstream-vera/Vera.ttf", 24)
#font = ImageFont.truetype("futuratm.ttf", 18)
font = ImageFont.truetype("arial.ttf", 18)
im = Image.new("RGB", (365,20), "#fff")
draw = ImageDraw.Draw(im)
draw.text((0, 0), "Test Images", font=font, fill="#000")
im.save("TestImg_EN.gif", "GIF")
font = ImageFont.truetype("osaka.ttf", 18)
im = Image.new("RGB", (365,20), "#fff")
draw = ImageDraw.Draw(im)
draw.text((0, 0), u"テストイメージ", font=font, fill="#000")
im.save("TestImg_JP.gif", "GIF")
