[mapserver-users] Raster reprojection

[Vladimir Guzmán]

I'm sorry to disturb you again with the same problem, but I can not 
figure out why do I have to install gdal library,
if I didn't need it with MS 3.4.

The error appears when I use a tiff image as background map, so I 
decided to use a png, with the same result:

*Warning*: MapServer Error in msDrawRasterLayer( PNG ): Raster 
reprojection supported only with the GDAL library. in 
*/usr/local/apache/htdocs/sig/admin/templates/mapa_form.php* on line *246*

*Fatal error*: Call to a member function on a non-object in 
*/usr/local/apache/htdocs/sig/admin/templates/mapa_form.php* on line *247*

But the error doesn't appear every time,  only in some zooms.

Do I have to install gdal anyway?
Why?

Thanks a lot,
