IMAQ Read File Inconsistency

[Michael Noll-Hussong]

Dear LabViewers,

I have a problem reading Tiff-Files using IMAQ Read File (Version 6.05):

Opening a 16-bit-grayscale picture taken from a microscopy program (FluoVIEW) the image does not look like it has to be - the whole color table seems to be shifted. Now I open another 16-bit-grayscale picture I took some weeks before the the same program (and before I updated that program) and everything looks o.k. - Nevertheless: Opening now my first image again the color representation is also o.k. The question is: What do I change with the IMAQ Read File settings when I open a Tiff picture ? Why is this effect resident because after calling "IMAQ Dispose" the color representation stays in its wanted (correct ?) form. Even if I close the VI and resta
rt it again everything is satisfying when you once loaded the image with the color table you wanted...

Thank you very much for any help in advance !

Mino. Does the behavior persists if you open the images in LabVIEW and then resave them as tiff files? I ask because tiff files have no formal standards, so if they're saved in another program, they could open inconsistantly in LabVIEW. Of course, another option is to use some other image format like bmp or jpg.

Dear Kyle V, your suggestion seems to work - open the tiff file and save it again establishes the wanted "color feeling". Unfortunately I have to use Tiff-files because of the microscopy software we use. Is there a way to avoid this load-save-load-look - procedure ?

Thanks a lot in advance,
