I downloaded some test images from:
<url:http://www.remotesensing.org/libtiff/images.html>
I then ran a test:
LIBTIFFPIC = r".\libtiffpic"
import Image, os
def main():
ok = error = 0
for root, sub, files in os.walk( LIBTIFFPIC ):
for i in files:
if i.endswith( '.tif' ):
full = os.path.join( root, i )
try:
tiff = Image.open( full )
except:
print "error:", full[ len( LIBTIFFPIC ) + 1 : ]
error += 1
else:
print "ok: ", full[ len( LIBTIFFPIC ) + 1 : ]
ok +=1
print "ok:", ok, "\terror:", error, "\ttotal:", ok + error
main()
The final line gave:
ok: 28 error: 33 total: 61
So I only managed to load 28 of the 61 test images, AFAIK I
have never installed anything special to get PIL to work
with tiff images.
As a side note The GIMP <url:http://www.gimp.org/> wouldn't load
some of the images too (I didn't test all), it had problems with
64 bit floating point images and images with RBGA data in them.
