screenshot not possible

[_Askin_]

hi,

I have following methods which I request/trigger over http-request:

def take_photo():
img = camera.take_photo(size = (640,480))
size = 480, 320
image = img.resize(size)
image.save(PICTURE_FILE)
return file(PICTURE_FILE).read()

def screenshot():
img = graphics.screenshot()
size = 480, 320
image = img.resize(size)
img.save(SCREENSHOT_FILE)
return file(SCREENSHOT_FILE).read()

first works fine and I am able to display the taken picture on the html website. BUT the second throws the following error on the phone:
Progr.geschl.:
HttpdMain
KERN-EXEC 3

any ideas why I get this error? THX for help!
regards,
Askin

This is caused by the Python environment, when running in the context of the web-server, being slightly different than the Python environment when running in the context of a UI application. Specifically (if you are versed in the S60 C++ API), when running under the web-server, there is no CCoeEnv instance.

The implementation of some component in that screenshot code above assumes that there is a CCoeEnv instance and since there is not, it leads to a crash, which is visible as that KERN-EXEC 3.

At one point I experimented with creating a CCoeEnv instance inside the web-server, but it caused other problems, so I abandoned that approach.

thx for your answer!
is there any effort to fix this or to make this feature possible in MWS? Or do I have other options to provide screenshots in MWS environment?

As far as I know, nobody is looking into this at the moment.

Byt PyS60 is fully open sourced, so just grab the code, make the fix, submit a patch, and I'm sure it will be accepted

Or do I have other options to provide screenshots in MWS environment?

You could make a native Apache module. In that case you have access to the complete S60 API and can do anything.

If that's not an option, then you could make a separate Python application that takes the screenshot and with which your request handler communicates.

Seems like this is more of a feature request for Python?
