looks like pyopengl 3.x returns a numpy array now instead of a string
by default... which breaks pygame.image.save on gl with pyopengl 3.x.
Here's a work around screenshot function for gl.
def save_screen(screen, filename):
def readScreen(x, y, width, height):
""" Read in the screen information in the area specified """
glFinish()
glPixelStorei(GL_PACK_ALIGNMENT, 4)
glPixelStorei(GL_PACK_ROW_LENGTH, 0)
glPixelStorei(GL_PACK_SKIP_ROWS, 0)
glPixelStorei(GL_PACK_SKIP_PIXELS, 0)
data = glReadPixels(x, y, width, height, GL_RGB, GL_UNSIGNED_BYTE)
if hasattr(data, "tostring"):
data = data.tostring()
return data
def saveImageData(width, height, data, filename):
""" Save image data """
surface = pygame.image.fromstring(data, (width, height), 'RGB', 1)
pygame.image.save(surface, filename)
data = readScreen(0,0, screen.get_width(), screen.get_height())
saveImageData(screen.get_width(), screen.get_height(), data, filename)
