Could you give a short test program that reproduces the problem? Sounds
like it only needs to read the file and maybe generate a thumbnail.

Hello,<br>
<br>
Thanks for the respons.<br>
<br>
Well, any trivial code may reproduce the problem :<br>
<br>
folder = /folder/with/image/files<br>
images = glob.glob(folder)<br>
for image in images:<br>
img = QtGui.QImage(image)<br>
if not img.isNull():<br>
set_thumbnail(img)<br>
<br>
If you have some RAW type of image in the folder, these files <br>
are converted in .tiff and the original files are lost.<br>
<br>
(RAW images are downloadable here : <a class="moz-txt-link-freetext" href="http://www.rawsamples.ch">http://www.rawsamples.ch</a>)<br>
<br>
I know, I can filter the list before process, but this isn't the
question.<br>
<br>
After reading the doc, I believed that Qt did not support RAW type.<br>
<br>
Actually, I'm implementing the support of RAW files in my application
Oqapy.<br>
I use, for this, the librairy Dcraw for extract thumbnails, metadatas, <br>
convert images to .tiff, etc.<br>
<br>
At this end and for testing, I have a folder with some images in RAW
type.<br>
<br>
The probleme : if I open (accidentally) this folder with the last
version of Oqapy,<br>
witch NOT yet support RAW type, all files is convert immediatelly in
.tiff format.<br>
<br>
Bad surprise, no ?<br>
<br>
I investigate in Qt doc, Faq and forum and, maybe, I'll post a bug.<br>
<br>
Thanks again.<br>
<br>
Cheers.<br>
