Screen capture problem

foxyfox

I need to take a screen capture of my Sparrow 1.4 game. Looking in Sparrow Wiki, I found an extension "SPDisplayObject+Image.h" from Shilo and incorporated it into the game. It seems to work on the Simulator, but testing on a device I got EXC_BAD_ACCESS (code = 1) on line:

glReadPixels(0, (stage.height*contentScaleFactor)-height, width, height, GL_RGBA, GL_UNSIGNED_BYTE, &buffer);

Does anyone know how to fix this problem?
Or is there another way to take a screen capture in Sparrow 1.4 that works?
Any help will be much appreciated. Thanks!

I finally found an extension that works on devices.
Just in case anybody else need to take screenshots with good old Sparrow 1.4, you can try SXScreenshot (download link here: http://forum.sparrow-framework.org/topic/screen-capture-with-sparrow ).
