Incomplete extent of raster after reprojection - corner missing

[Delfos, Jacob]

Hi List,

I have a raster which I am reprojecting on the fly from LCC to either UTM or Latlong. I just realised that in each mapimage, it misses a small corner at the bottom-right. The background colour of the map shows through. It appears that the slice being cut out of the raster-image prior to reprojection is too small; after reprojection, the cut-out slice doesn't cover the map-image completely, because of the distortion due to reprojection. This problem occurs every time the layer is drawn. 

I have attached part of the map-image. The background of the map is light yellow, as is the bottom-right of the image. The height of the corner missing is typically about 8% (compared to mapimage-height). It occurs in php_mapscript version 4.4 and 4.6, using gdal 1.26 and 1.31 respectively. The raster is an ecw.

It's no major drama, but I was hoping it might be easy to fix.....

Regards,

Jacob
