Hi,
I'm parsing some output from a command that I execute with os.popen.
This command (tiffinfo) displays information about Tiff images. The
solution I'm using does work, but I'm wondering there's a 'better' way
to do it.
Here's the typical output from the command:
[start output]
TIFF Directory at offset 0x8
Subfile Type: (0 = 0x0)
Image Width: 12000 Image Length: 16800
Resolution: 400, 400 pixels/inch
Bits/Sample: 1
Compression Scheme: CCITT Group 4
Photometric Interpretation: min-is-white
Samples/Pixel: 1
Rows/Strip: 16800
Planar Configuration: single image plane
DocumentName: buzzsaw.com
[end output]
I need to return the size (width & length) in inches of the Tiff. So I
need the information on lines:
Image Width: 12000 Image Length: 16800
Resolution: 400, 400 pixels/inch
Example: 12000 / 400 = 30 & 16800 / 400 = 42, so the Tiff is 30" x 42".
Here's how I'm doing it:
[start code]
import os
import re
filename = 'C:/Tiff Files/Large Tiffs/Nbm001.TIF'
command = 'tiffinfo "%s"' % (filename)
p = re.compile('\d+')
def getTiffWidthLength():
tmp = []
s = []
r = []
for line in os.popen(command).readlines():
if line.startswith(' Image Width:') or \
line.startswith(' Resolution:'):
tmp.append(line.strip(' \n'))
s.append(tmp[0])
r.append(tmp[1])
for wl in s:
size = p.findall(wl)
for i in r:
res = p.findall(i)
width = int(size[0]) / int(res[0])
length = int(size[1]) / int(res[1])
print (width, length)
if __name__ == '__main__':
getTiffWidthLength()
[end code]
Like I said, it does work but can it be improved upon?
Thanks for any help.
Bill
