gdaltindex raster files (MapInfo gif + tab format)

[Zhonghai Wang]

Hi guys,

I get some info again from the "Raster Dat Access" document, and it
indicates that:

****
GIF: If GD is configured with GIF (OUTPUT=GIF) support, then MapServer will
also be able to read GIF files for raster layers. The only way to
georeference GIF files is with a world file.

If GD is not configured with GIF support, it may still be available in GDAL

****

Is it true that GIF raster images can only be georeferenced with a
worldfiles? TAB files are not supported?
