      Description

      This image uses 32-bit floating point values for encoding pixels. It's not a widely used format and even my Photoshop CC rejects it ("Unsupported bit depth"), but my application has no problem reading and displaying it with libtiff. However, when I attempt to load it with QImage, access violation occurs.

      The TIFF file is too large to attach directly (300 MB), so here's the cloud storage link: https://mega.nz/file/0mokiYYR#-xKleYM6aVfo2gvgTXzUY_w31zk_SJj-fCFtpcPOZNc
