<div dir="ltr">Folks,<div><br></div><div>To smooth out deployment of PROJ.4 at my workplace, I have made some</div><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> int (*FSeek)(PAFile file, long offset, int whence);</div><div> long (*FTell)(PAFile file);</div><div> void (*FClose)(PAFile);</div><div>} projFileAPI;</div></div><div><br></div><div style>I have reworked the the init file and grid shift file access goes through this</div>
<div style>and provided a default "stdio" based implementation. These changes are</div><div style>now available in svn and I have yet to actually try it out beyond use of the</div><div style>stdio based implementation, but I'm interested in if anyone sees this as</div>
<div style>useful or has thoughts on how it ought to be done better.</div><div style><br></div><div style>I'm also contemplating an optional build mechanism that will build grid </div><div style>shift files and init files right into the shared library for easy deployment</div>
<div style>though I'm not sure exactly how I'll do that yet.</div><div style><br></div><div style>I have also updated svn in preparation for a 4.9.0 beta release which I </div><div style>hope to do in the next week or so. I'll try to review the bug database and</div>
<div style>fix anything I can but this is a good time to bring any pressing bugs to the</div><div style>table. So far the NEWS file contains:</div><div style><br></div><div style><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 style>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>
