Metadata can be read ok, as can label images. Error printed out:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>TIFFFillTile: 0: Invalid tile byte count, tile 75<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>(the tile no. varies from about 64-75)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Which causes openslide to return the error “TIFFRGBAImageGet failed”, and of course all subsequent calls to fail. I’m using openslide under windows (pre-built from a couple of months back). Am I potentially doing something wrong? Or is this a bug (ImageScope opens the same images fine). One example:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>openslide_read_region(..,..,0,0,2,1024,1024), on an image of size 41832 x 24971, so this should be well within the image. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Derek<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
