taking a screenshot

korakot (Korakot Chaovavanich) — Sun, 19 Jun 2005 22:28:13 GMT

In py_s60 1.1.0, we can take a screenshot using camera module.
In 1.1.3, however, the feature is moved to the new graphics module.

Here's a quick example.



import graphics

im = graphics.screenshot()

im.save(u'C:\\test.png')

You may notice the difference. Now you can save it in 'jpg' or 'png'
as you like by specifying the filename.
