Invalid TIFF directory; tags are not sorted in ascending order. `TIFFReadDirectoryCheckOrder'

[punith8626]

Hello,

I am trying to convert tiff file and i get below error message when i try to convert tiff to png.

Code: Select all

convert.exe: Invalid TIFF directory; tags are not sorted in ascending order. `TIFFReadDirectoryCheckOrder' @ warning/tiff.c/TIFFWarnings/768.
convert.exe: ASCII value for tag "Artist" contains null byte in value; value incorrectly truncated during reading due to implementation limitations. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/768.
convert.exe: Depreciated and troublesome old-style JPEG compression mode, please convert to new-style JPEG compression and notify vendor of writing software. `OJPEGSetupDecode' @ warning/tiff.c/TIFFWarnings/768.
convert.exe: Missing JPEG tables. `OJPEGReadHeaderInfoSecTablesQTable' @ error/tiff.c/TIFFErrors/508.

Is there any solution for this?
I am using ImageMagick-6.7.7-Q16 with windoes 7 environment.

Is the final image created? If so you may be able to ignore the errors.
What happens if you try a file from another source - if this works it could be the problem with the software that creates the tiff. Use different software to create it
What is your actual code?
Have you tried in a different Imagemagick version?
You need to upload the problem file somewhere so the members here can try it.

The first 3 are just warnings and can be ignore. The last implies there is a malformed TIFF which is missing the JPEG tables, assuming it is JPEG compressed.

- convert C:\Users\Desktop\lense\NotWorking.tif C:\Users\Desktop\lense\NotWorking.png
- I tried with image magic versions like ImageMagick-7 and ImageMagick-6.7.7-Q16 so far not output. We get output as black screen
- I have restriction to upload the corrupted file to forum
- I tried the convert same image using laserfiche and coolutils and I am able to convert it.

Tiff is a very customizable format. I suspect those tools are not sensitive to proper tiff formatting. Libtiff may be more sensitive to such changes. So I still think this is a malformed or very customized image TIFF formatting that libtiff will not handle.

Can you generate a TIFF image that is not proprietary and provide a link to it here?

I tried with coolutils and i am able to convert it but not with image magic

Any update on this?

tiffcp and Windows Photo Viewer can't open it.

Gimp doesn't complain, and makes an image that seems entirely black.

IM complains, but makes an image that is entirely black.

A developer may take a look, but I doubt that IM will be modified to read this file.

your data is located at 2046 byte point and its byte count is 477825. As everyone says, this is likely to be a non-standard tiff file, however, when compression is old-jpeg, raw data is sometimes found there.

Well, it looks JFIF format, so you can extract the data cutting the header (and the trailer if it has).

Code: Select all

$ tail -c+2047 NotWorking.tiff | head -c 477825 > tmp.jpg
$ identify tmp.jpg 
tmp.jpg JPEG 1700x2200 1700x2200+0+0 8-bit Gray 256c 477825B 0.000u 0:00.000

Now I can see the file with display command and can convert it to png.

Is 2046 and 477825 is common for all the files ? If not How do i get to know which bytes needs to remove.

See

Code: Select all

StripOffsets (273) LONG (4) 1<2046>
StripByteCounts (279) LONG (4) 1<477825>

from command output above. If all your files are created by same software, there is a chance to be able to extract the file same way. tiffdump command comes from libtiff.

Hello,

Sometimes when i run the tiffdump command I get permission denied.
