<p dir="ltr">The release sounds good. I'm really looking forward to trying out Charles' geod interface too.</p>
<p dir="ltr">Just wondering if the Robinson issue raised by Edward Campbell on this list was on the radar for this release? As it stands the Robinson projection is pretty broke at latitudes of around 40°...</p>
<p dir="ltr">All the best,</p>

<div>changes so that all file access can go through a virtual layer. This virtual file</div><div>api looks like the following, and is associated with a "context" (projCtx). </div>
<div><br clear="all"><div><div>typedef struct projFileAPI_t {</div><div> PAFile (*FOpen)(projCtx ctx, const char *filename, const char *access);</div><div> size_t (*FRead)(void *buffer, size_t size, size_t nmemb, PAFile file);</div>

<div>and provided a default "stdio" based implementation. These changes are</div><div>now available in svn and I have yet to actually try it out beyond use of the</div><div>stdio based implementation, but I'm interested in if anyone sees this as</div>
<div>useful or has thoughts on how it ought to be done better.</div><div><br></div><div>I'm also contemplating an optional build mechanism that will build grid </div><div>shift files and init files right into the shared library for easy deployment</div>
<div>though I'm not sure exactly how I'll do that yet.</div><div><br></div><div>I have also updated svn in preparation for a 4.9.0 beta release which I </div><div>hope to do in the next week or so. I'll try to review the bug database and</div>
<div>fix anything I can but this is a good time to bring any pressing bugs to the</div><div>table. So far the NEWS file contains:</div><div><br></div><div><div>4.9.0 Release Notes</div><div>-------------------</div>
<div><br></div><div> o Implement new virtual file api (projFileAPI) so that all access to grid</div><div> shift and init files can be hooked.</div><div><br></div><div> o Replace geodesic implementation with one from Charles Karney and add a </div>
<div> supported public interface (geod_interface.h).</div><div><br></div><div> o Upgraded to EPSG 8.0.</div><div><br></div><div> o Removed old (deprecated) Java bindings in favor of the new api introduced</div><div> in 4.8.0.</div>
<div><br></div><div> o Various bug fixes and cleanup.</div><div><br></div><div>Best regards,</div></div>-- <br>---------------------------------------+--------------------------------------<br>I set the clouds in motion - turn up | Frank Warmerdam, <a href="mailto:warmerdam@pobox.com" target="_blank">warmerdam@pobox.com</a><br>
