hi,
i am wondering if there is a faster way to find the number of frames or pages
in a 3-d tiff image than doing something like this:
img = Image.open("myFile.tif")
frame = 0
try:
while 1:
img.seek(frame)
frame = frame + 1
except EOFError:
img.seek(0)
pass
any hints on this? i looked through all the tags and did not find anything that
tells the number of frames in the 3-d tiff images i am working with. this code
works, but seems to be somewhat slow. also, along these lines, i wonder if
there is generally any faster way to read these multi-frame tiff images than
what i list above (assuming i also then assign img to some 3-d array i made
using numpy). doing so with my images can take up to twice as long as if i
read the same images in matlab (an average of 1.88 times slower when i test
with a bunch of different images). even as compared to my matlab code, the
actual read time is not prohibitively slow, but is considerably slower than any
other means i have of reading the images, so i am guessing there must be a
better way for me to read the data than this try: statement.
thanks for any insight!
bryan
