ImageLoad error - System error #-8970

Hi everyone,

I have a new strange issue. We use a microscope that creates .tif images. I would like to load them in Igor to do some image analysis, but loading fails and I get a strange error "ImageLoad error - System error #-8970".
Do you have any idea how to overcome this? I tried to load the images pretending they are another format e.g. bmp or jpg, but that gives the same error.
If I open the image in another software and save it as .bmp, then Igor works fine but it is really painful to convert by hand 100's of images.

I attached an example image, in case someone wants to try it out. Ironically I could not even attach the .tif here, it is zipped and apparently cursed :)

thanks a lot! 110.zip
Could you post your operating system, the Igor version, and the command used to 'load' the image?

In case you use IP6 - is QuickTime installed?

I got the following messages in IP7:
ImageLoad/T=tiff/O/G "Path:110.tif"
  Image from: 110.tif
  TIFFReadDirectory: Unknown field with tag 347 (0x15b) encountered
  TIFFReadDirectory: Unknown field with tag 33560 (0x8318) encountered
  Path\110.tif: JPEG compression support is not configured
  Path\110.tif: JPEG compression support is not configured

and only zeros in the created wave (the dimensions are ok though)

Thanks for your answer, I use IgorPro 6.32 on a Windows 7.
I tried all sorts of loading ways and always the same error.

ImageLoad/T=tiff/G
ImageLoad/T=tiff


in general

Hi Davide,

I tried to load your image with IP7 on a Windows 7 computer. The image loads without any error messages but - as already reported by HJ - contains only 0.
I guess that Igor has some difficulties with jpg encoded TIFF images. I tried another image with the same encoding and this showed the same behaviour. Igor will load a "real" jpg image, so jpg in principle seems not to be the problem. As a quick solution you could convert all your pictures with a batch converter like IrfanView.

Greetings,

Igor 6.32 is a little old (maybe apply an update?) and potentially related to a QickTime issue (afaik IP6 has no native TIFF import).

However, I don't think this causes your trouble. Batch conversion of the images is most likely to way to go.
But maybe one of the WM gurus has another idea...

I'm getting the same error with the latest IP6.

My linux box knows about the image:
tron@abakus:~/thomas$ tiffinfo 110.tif TIFFReadDirectory: Warning, Unknown field with tag 33560 (0x8318) encountered.

And with the latest IP7 I get:

ImageLoad/T=tiff/O/G "h:110.tif" Image from: 110.tif TIFFReadDirectory: Unknown field with tag 347 (0x15b) encountered TIFFReadDirectory: Unknown field with tag 33560 (0x8318) encountered H:\110.tif: JPEG compression support is not configured H:\110.tif: JPEG compression support is not configured

So this looks like you gotta contact WM support.

Thank you all for the efforts. I am now batch converting with Irfanview as suggested above, so I can proceed with the programming. Sure it would be nice to fix the original problem somehow.
Apparently I have one more reason to update to IP7

As others have pointed out, your version of Igor is old. We have been shipping IP7 for about 8 months now so it is time to upgrade.

Also as mentioned by others, you have a TIFF file that contains a JPEG compressed image. JPEG in TIFF is not supported in Igor. In fact, I find it difficult to believe that someone would consider using JPEG compression in a microscope image. You never know... maybe they are trying to optimize performance for some phone app. and did not feel like using straight JPEG file with EXIF tags.

If your application requires quality images you might want to find if there is a different format that you could save the images. The conversion that you describe still has a step that involves JPEG so it may not be ideal.
