[Gdal-dev] Patch to get jpg driver to read world files with .tfw extension

[Eric Dönges]

It seems that some people use world files with a .tfw extension  
instead of
the .jpgw and .wld extensions the jpeg driver looks for, so I've  
patched it to
look for .tfw and .tifw as well. Which leaves me wondering - is this  
the correct thing
to do ? Of all the other drivers that can read world files, only the  
(Geo)TIFF
(obviously !) and PNG drivers search for .tfw and .tifw files. If the  
JPEG driver should
look for .tfw and .tifw files, shouldn't all other drivers that can  
read world files
do as well ?

With kind regards,
Eric
