[Mapserver-users] GDAL / GIF misunderstanding?

Tue Mar 4 10:21:34 PST 2003

Hi,

I'm wondering if I'm confused.

I've added a WMS client layer whose source is only available in GIF to a map
file. I've got GDAL installed with internal GIF support. I'm using the map
as a WMS server. As I don't have GIF output support, I'm requesting the
output format set to image/png. When requesting a map, I see:

<ServiceExceptionReport version="1.1.0">
<ServiceException>
drawGIF(): Image handling error. GIF support is not available.
</ServiceException>
</ServiceExceptionReport>
Content-type: text/html
<HTML>
<HEAD><TITLE>MapServer Message</TITLE></HEAD>

<BODY BGCOLOR="#FFFFFF">
drawGIF(): Image handling error. GIF support is not available.
</BODY></HTML>

Do I misunderstand? I thought that if I use GDAL, I should be able to read
the GIFs. I'm not trying to write GIF, but the drawGIF() message above seems
to indicate that I'm trying to do so. I'm definitely requesting the map
using FORMAT=image/png in the WMS request.

Any ideas would be appreciated.

Doug
