Tiff metadata - sudecki - Aug-09-2018
Hi, I am new on the forum, I search a solution for my work. I process Tiff image of Olynpus miscroscope. And inside image, you can find some details of acquisitions but you can't read with anyEXIF reader.
I try to do a code to read of original image and write on a proccesing image. I am sorry it is not beautiful code. But when I do this, i create a corrupt file. I try a lot Exif or Tiff libreary. But any can't read these elements.
Can you help me?
My code:
nfc=path+nom
######Read metadata on the original file
fd = open(nfc, encoding='utf-16-be')
d= fd.read()
x_start = d.find('analySIS')
x_end = d.find('Solutions')
x_str = d[:xmp_end+11]
x_str2 = d[xmp_start-16:]
fd.close()
######Write
#read the image data
fd = open(os.path.join(path2,nom), encoding='utf-16-be')
d= fd.read()
fd.close()
#add metadata on image of the orinal image
d=x_str+d[140:]+x_str2
fd = open(os.path.join(path2,nom), 'w+',encoding='utf-16-be')
fd.write(d)
fd.close()And the image file: (You can open with notepad, informations I want are at the begening and at the end.)Image TIFF
I work on windows 7 with Python3.6 64bits, because I process image with an IA.
Thanks

Hi, I have found
######Read metadata on the original file
fd = open(nfc, 'rb')
d= fd.read()
xmp_start = re.search(b'analySIS',d)
xmp_end = re.search(b'Solutions',d)
xmp_str = d[:xmp_end.span()[0]+11]
xmp_str2 = d[xmp_start.span()[0]-16:]
fd.close()
######Write
img2.save(os.path.join(path2,nom))
fd = open(os.path.join(path2,nom), 'rb')
d= fd.read()
fd.close()
d=xmp_str+d[140:]+xmp_str2
fd = open(os.path.join(path2,nom), 'w+b')
fd.write(d)
fd.close()
