I chose kakadu and everything works fine. However, I<br>decided to try with OPENJPEG 1.5 since it is open-source and it seems<br>to be the future reference. I have two main problems that I want to<br>share:<br><br>1. The information is shown in the command prompt every time I run the<br>program. I redirect the output to a "garbage" txt as a solution.<br>However, it works for "j2k_to_image" but not for "image_to_j2k". I<br>think it would be nice an option to avoid these information like in<br>kakadu (-quiet).<br><br>2. I lose the georeference of the pixels. When I convert to TIFF I<br>lose it and I found no option in the functions. GDAL can read the<br>geoinformation of JPEG2000 but it cannot be directly updated to a<br>JPEG2000 file. Therefore, that is for me a limitation. Probably, there<br>are some other options... but anyway, it would be nice if the<br>application recognises that information automatically like with<br>kakadu.<br><br>Thanks in advance<br><br>-- <br>You are subscribed to the mailing-list of the OpenJPEG project (<a href="http://www.openjpeg.org">www.openjpeg.org</a>)<br>To post: email to <a href="mailto:openjpeg@googlegroups.com">openjpeg@googlegroups.com</a><br>To unsubscribe: email to <a href="mailto:openjpeg+unsubscribe@googlegroups.com">openjpeg+unsubscribe@googlegroups.com</a><br>For more options: visit <a href="http://groups.google.com/group/openjpeg">http://groups.google.com/group/openjpeg</a><br>For more info about OpenJPEG main partners : visit <a href="http://www.tele.ucl.ac.be">www.tele.ucl.ac.be</a> (UCL) and <a href="http://www.intopix.com">www.intopix.com</a><br></div></blockquote></div><br></body></html>
