Reprojection problem

That sounds very strange!  Can you post the LAYER definition for the troublesome layer, or at least the PROJECTION block for it?

Subject: [UMN_MAPSERVER-USERS] Reprojection problem

Hello,

I recently upgraded from 3.6.6 to 4.6.1, and now I'm having problems with a map that reprojects a single layer ...

I have a MAP level PROJECTION object, and one layer with a different PROJECTION than the others ... (The map is in an LCC projection, and the layer in geographic).

This used to work fine in 3.6.6, but now I get "msDrawMap(): Image handling error. Failed to draw layer named 'featureannotate'." ... That layer being the one in geographic that should be getting reprojected.

If I take out the PROJECTION parameter of the layer, no errors!  I tried moving it's definition with the layer, which didn't change anything ... I also tried using both epsg codes and in-line definitions, which also didn't help :(

I was using PROJ 4.4.5 ... Upgraded to 4.4.9 ... That didn't help.  I re-compiled MS just to be safe, the problem remains ...

I have a WMS server running off the same setup without complaints (including reprojection).  The shapefile looks ok, shpdump/shptest and dbfdump didn't produce anything out of the ordinary ...

Any ideas?

Thanks!
