Hello,
I use PIL 1.1.6 and Python 2.5. I have a simple method drawing a
watermark into images. Input parameter is a URL of the original image
and out is the watermarked image. The method works but after many
calling the python process consumes more and more memory until it
crashes totally.
Could anyone advise me how to solve the problem? Is there anything
which I have to delete or close?
def draw_watermark(self, REQUEST):
address = REQUEST.form['url']
url = urllib.urlopen(address)
fil = StringIO(url.read())
url.close()
img = Image.open(fil)
fmt = img.format
if img.mode != 'RGBA':
img = img.convert('RGBA')
COLOR = (255,255,255)
draw = ImageDraw.Draw(img)
f = ImageFont.truetype('C:/Windows/Fonts/Verdana.ttf', 11,
encoding="unic")
txt = "Copyrighted"
draw.text((5,5), unicode(txt,'UTF-8'), font=f, fill=COLOR)
del draw
out = StringIO()
img.save(out, fmt)
REQUEST = self.REQUEST
REQUEST.RESPONSE.setHeader('Content-Type', fmt)
return REQUEST.RESPONSE.write(out.getvalue())
Thank you in advance.
Karel
