python - Create set of random JPGs -

-

here's scenario, want create set of random, small jpg's - anywhere between 50 bytes , 8k in size - actual visual content of jpeg irrelevant long they're valid. need generate thousand or so, , have unique - if they're different single pixel. can write jpeg header/footer , random bytes in there? i'm not able use existing photos or sets of photos web.

the second issue set of images has different each run of program.

i'd prefer in python, wrapping scripts in python.

i've looked python code generate jpg's scratch, , didn't find anything, pointers libraries good.

if images can random noise, generate array using numpy.random , save them using pil's image.save.

this example might expanded, including ways avoid (very unlikely) repetition of patterns:

import numpy, image  n in xrange(10):     = numpy.random.rand(30,30,3) * 255     im_out = image.fromarray(a.astype('uint8')).convert('rgba')     im_out.save('out%000d.jpg' % n)

these conditions must met in order jpeg images:

  1. the array needs shaped (m, n, 3) - 3 colors, r g , b;
  2. each element (each color of each pixel) has byte integer (uint, or unsigned integer 8 bits), ranging 0 255.

additionaly, other way besides pure randomness might used in order generate images in case don't want pure noise.

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
