I finally resolved my problem !
I look the 'conditionaltranspose' action. It helps me understand some little things.
I used the "values" method of the Action class, for get "info[('filename')]".
This is how my action is for now :
from core import models
from core.translation import _t
def init(cls=None):
global Image, ImageDraw, ImageFont
import Image, ImageDraw, ImageFont
def numerotationpage( image, page_number, font, color, oddright):
position= int(page_number)%2 and (oddright and (1000,800) or (10,800)) or (oddright and (10,800) or (1000,800))
font = ImageFont.truetype(font, 50)
ImageDraw.Draw(image).text(position, page_number, font=font, fill=color)
return image
class Action(models.Action):
label = _t('Numerotation page')
author = 'orfvz'
email = 'orfvz.jywa@gmail.com'
init = staticmethod(init)
pil = staticmethod(numerotationpage)
version = '0.1'
tags = [_t('default'),_t('text')]
__doc__ = _t('Add page number on image')
def interface(self,fields):
fields[_t('Font')] = self.FontFileField('Free Sans')
fields[_t('Color')] = self.ColorField('#000000')
fields[_t('Oddright')] = self.BooleanField(True)
def values(self,info, pixel_fields={}):
page_number = info[('filename')][-2:]
font = self.get_field( _t('Font'), info )
color = self.get_field( _t('Color'), info )
oddright = self.get_field( _t('Oddright'), info )
return {
'page_number' : page_number,
'font' : font,
'color' : color,
'oddright' : oddright,
}

The 2 last characters of my image's name are their page's number.
I used it for know if it's an odd or even page and i write the number of the page at the right or the left bottom.
I think it will be useful to have some documentation about all the methods and attributes of the Action class.
Some docs with example about all fields available, should be very helpful too. I don't understand how take value of 'FileSizeField'.
