already found the option for flip, its "dds_flip" for the reader/writer
but still got the color-problem with uncompressed format...

hi robert!
Try this dds-file, for example... (it happens both, with and without
embedded mipmaps)
http://stud4.tuwien.ac.at/~e0425503/appearsBlue.dds
http://stud4.tuwien.ac.at/~e0425503/appearsBlue_nomip.dds
It's a kind of wooden texture, and appears completely blue...
Regarding the flip-issue: when loading a dds-file with mipmaps and
applying osgImg->flipHorizontally() afterwards, only the mip-level 0
gets is flipped, right?
This results in terribly filtering issues.... is there an option for
the osg-dds plugin to flip at loading time?
In prior Discussions about the flip-issue someone mentioned a "flip-y"
- option in NVIDIAs dds Photoshop-Plugin, but I didn't find any...
greets,

Hi Heninrich,
I haven't seen/heard of this problem before. Could you post a
problem dds file.

Hi,
I tried out the DDS-Loader using images generated by NVIDIA
dds-photoshop-plugin, and had the following issues:
.) when using uncompressed format (3. or 4 channel) I get incorrect
colors (looks like only Blue / Green colors)
.) the image is always horizontally flipped
-> I know this issue was already discussed in the mailing
list, but
I couldn't find any general solution for that... NVIDIA's own
DDS-Loader
for OpenGL
loads all files correctly, so I guess the flipped image
is not
intended to look like that....
Does anyone have the same issues? Any solutions for that?
I like the dds - fileformat because the artists have more options to
choose between different compression-formats, and are able to
manipulate the mip-map-levels (fading color, sharpening -> esp. on
normal maps. etc....)
thnx
