Thanks for repairing the code, will try to remember ;-)

Grr forgotten to include code in this forum, so sorry

I got from github a file for sounds ...
starting with : from ctypes import c_void_p, c_char_p and some more ...

My pythonista contains wel eg. numpy (new sinds?) but not ctypes ..

So either say, no not yet, otherwise how to get it inluded ;-)

Please,

I saw, that so much has been done with Pythonista

My last problem was to set a date onto a number of images ..
using this

import photos as ph
from PIL import Image as im
n = ph.get_count()
print 'size is',n
#aanname datum photo is laatste!!!
todolijst = [el for el in range(n-5, n-1)]
print todolijst
def doimg(n):
        img = ph.get_image(n)
        return img
i15 = doimg(todolijst[-4])
print i15.size
#import Sketch
#print (ph.get_count())
nrim = ph.get_count()
dateImg = ph.get_image(-1) #laatste moet het date plaatje zijn met Sketch te maken
dimgsize = dateImg.size
print 'imgsiz',dimgsize
i15 = i15.resize(dimgsize)
print i15.size
res = im.blend(i15,dateImg,0.2)
res.show()
ph.save_image(res)
'''
import photos as ph
from PIL import Image as im
m_plaatjes =  4 #ij changeME
#Aanname: laatste plaatje bevat datum van Sketch gemaakt
#Daarvoor m_plaatjes om met datum te blenden!
n = ph.get_count()
print 'size is',n

#todolijst = [el for el in range(n-5, n-1)]

#print todolijst

def getImg(nr):
              img = ph.get_image(nr)
              return img
#i15 = doimg(todolijst[-4])
def blendAllImageMetDatum(m_plaatjes,n):
    dateImg = getImg(n-1)
    dimgsize = dateImg.size
    welke = n - 2
    for i in range(m_plaatjes):
        tmp = getImg(welke)
        tmp = tmp.resize(dimgsize)
        res = im.blend(tmp, dateImg,0.1)
        res.show()
        ph.save_image(res)
        welke -= 1

blendAllImageMetDatum(m_plaatjes,n)

def overlay2img(n):

    t1 = getImg(n-1)
    t2  = getImg(n-2)
    res = im.blend(t1,t2,0.5)
    res.show()
    ph.save_image(res)

#overlay2img(n)

and the gift to make a date picture: Sketch.py

Will pythonista still work, if I upgrade my Ipad to IOS7?
Greets Peter

Thanks, will try ...(later)

isn't it that 'shellista' does what you want?
(a gist is found here ..., to lazy to find it here back for you, sorry)

If time is a problem, in the foregoing century I replaced divisions by multiplications ...
Will check the difference on an Ipad 2 ;-)

Does tmp = tmp + 1 be as efficient as tmp += 1 ???

And I will look at the most inner loop for ...

EDIT:
nothing changed I get 'white' vertical lines 'moving' from left to right,
how could that be avoided (repaired?)

Maybe have a look here: http://www.daniweb.com/software-development/python/threads/277522/gui-scientific-calculator-homework

Maybe something nice to build with Pythonista?
Ideas of which classes one needs ... and then and building it 'testdriven' with unittest
(http://docs.python.org/2/library/unittest.html) ?!

Hi now an more or less working source can be found:
https://gist.github.com/4245408

See a picture first?

Comments and found errors are welcome ;-)

Thanks, will have a look ;-)

What is an app_key ( for to set in the source) ?
