Description
Program in PHP/mapscript uses zoompoint to zoom in. With complicated 'MULTIPOLYGON' layers included , ie stewardship layers in example attached map will display only zoomed out all the way in releases greater than 5.0.2. Have tried 5.2.3, 5.4.2, and 5.6.1 all with same failure.

Can you supply the layer name of interest, an extents that works, and an extents that does not work?
Ideally, use those to test with shp2img and see if the problem is in the core mapserver engine, rather than mapscript.
Finally, for extra bonus marks, dump the database table to a shape file and see if the problem manifests there too.
The more you can narrow down the problem and the reproduction of the problem, the easier it is for a developer to quickly pick it up and fix it.
Thanks!

Hi,
I turned on layers counties and gapown and and set extent to a zoomed extent. Ran shp2img compiled in 5.0.2 and produced a map. Ran shp2img compiled with 5.6.1 and failed to make a map. Attached output with -all_debug 2 for both. layers gapown, gapman, and gapsta all fail in same way. These 3 layers were made from same input by a pl/pgsql script.
will work on getting a test using the shapefile.

Hi,
Attached output for mapserver 5.6.1 at default extent, which always works.

What failure do you get ? I think I'm not getting the same bug than you... with 5.6.1/trunk... using the extent 806873 188697 969149 273715, mapserver/shp2img never ends. I'm investigating in the problem...

It looks like your POLYGONS (I've only tested gapown) have an invalid exterior ring (probably not closed ?) and that AGG is unable to add a pattern/path for the HATCH symbols with those polygons. The code has a little bit changed in the mapserver agg renderer. Perhaps tbonfort would know what's the problem. Everything seems to work if we use GD renderer rather than AGG, or if we simply don't use HATCH symbol. basic

effectively. basic999, may you confirm us that we are experiencing the same behavior? to close this ticket.

I have tested both of these changes, ie use GD instead of AGG and comment out the hatch-lines and with either of these changes did draw a map using mapserver-5.4.2/shp2img.
At this point do I need to make a choice to stay with 5.02, not use AGG or not use the hatch, or will this be fixed when #3207 is resolved?

We will of course fix this bug, not sure when though. I'm going to add you in CC in the other ticket.
Closing this ticket since it is a duplicate of #3207.

I applied patch from #3207 on 5.6.1. It worked and my site is now running 5.6.1 with no problems.
Thanks.
database dump and source code were too large for upload. ftp from ancalagon.zo.ncsu.edu/anonymous In /out/OG_pub get database dump ncgap_12_28_2009 and code bug.tar.gz.
