<p>Sebastian,</p>
<p>JPEG compression is definitely not needed, nor appropriate for
the kind of TIFF files PROJ handles. The grid files distributed by
PROJ use the DEFLATE compression method, which requires libtiff to
be built against zlib</p>

<p class="MsoNormal">I am trying to build PROJ9 for my android
application. At the moment it works in a proof of concept with
"ENABLE_TIFF=OFF".<o:p></o:p></p>
<p class="MsoNormal">Now I want to build and integrate TIFF

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does PROJ9 need JPEG support in the libtiff
library. If not, it will be a bit easier.<o:p></o:p></p>
