display-im6.q16: unexpected end-of-file on miff files

[user001]

Conversion to miff fails on some images, such as this one: https://ufile.io/2v40w

This works fine:

Code: Select all

convert a.tif -depth 8 -colorspace gray PNG:- | display -

whereas this fails:

Code: Select all

convert a.tif -depth 8 -colorspace gray miff:- | display -

The error is:

Code: Select all

display-im6.q16: unexpected end-of-file `/tmp/magick-18299r_gUYwVHKpo': No such file or directory @ error/miff.c/ReadMIFFImage/1621.

Even if the image is first converted to a PNG, the error still results when attempting to convert to miff:

Code: Select all

convert a.tif -depth 8 -colorspace gray PNG:- | convert - miff:- | display -

The error is image-specific, as it does not occur on other images.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.

That was very fast, thanks!

FYI: I downloaded your tiff file. But Preview on my Mac will not open it. Also when I open in GIMP, the file opens but I get several messages.

GIMP Message
Calling error for procedure 'gimp-image-set-resolution':
Image resolution is out of bounds, using the default resolution instead.

TIFF image Message
Sorry, can not handle images with 64-bit samples

TIFF image Message
Unsupported layout, no RGBA loader

Yes, it's a 64-bit tiff, so the majority of image viewers fail to open it. The resolution is 65 nm/px, expressed as cm^-1 (TiffTag RESUNIT_CENTIMETER = 3, https://www.awaresystems.be/imaging/tif ... nunit.html). The resolution shouldn't matter to an image viewer. I'm not sure about the RGBA loader complaint. It's a valid tiff as far as I can tell (header and pixel data).

Code: Select all

I can confirm that the patch worked. Thanks again!
