small example to test

When the document contain 16bit tiff image, it is either not loaded at all, or shown distorted, or shown as single color rectangle.
Comment 1 Jean-Baptiste Faure 2014-02-01 20:49:02 UTC
Please, could you attach a screencopy showing how this test file looks in MS-Powerpoint? 

Tested with LO 4.1.4, LO and the master on Ubuntu 13.10 x86-64; each shows a black rectangle.
I guess it is not what is expected. So set status to NEW.

Best regards. JBF

Sorry, not have powerpoint available just now, image should look like this (some sort of grid)
Comment 3 steve 2015-04-26 09:05:06 UTC
I don't think this is a bug. The attached test file shows identical in MS Powerpoint and LO (screenshot attached).

In both cases a back square is shown in the middle of the document. So this is not a LO bug, but it seems something with the file is broken.

Then downloaded .tiff file and added that in MS Powerpoint. Save file. Open saved file with LO → all is good.

WORKSFORME (attaching screenshots)

It is working right only in recent versions of powerpoint (2013 should work, 2007 should not, I've no 2010 version).
Comment 7 V Stuart Foote 2015-08-06 04:05:06 UTC
Confirming this is still an issue filter parsing with LibreOffice, either opening into Draw or on insert into Draw the TIFF raster is rendered as a solid black image.

This bug is just: load TIFF attachment 93197 [details] in LO (Writer, Impress).
Bug is black rectangle.
