> loader to un-premultiply the alpha (now in the codebase).
Applying the code brightens the semi-transparent portion, but the black edges are still there (same on both osgviewer and FlightGear).
Therefore I believe that the alpha channel is completely ignored (on png, gif, tiff, etc...). I tweaked and tweaked and finally got a workaround.
Please commit the enclosed file to fix these issues.
My workaround is a bit tricky (and some lines are even weird for me), but it resolves the black edges.
These workarounds also work on GIF, TIFF, TGA, and PSD as long as I've tested so far.
Please read this for more info on this issue:

I'm very happy if some of you guys find a better means of solving the black edges.

"Here is our freshly baked 3DS reader/writer (named 'v0.5' to differentiate from previous one). Changes are against trunk rev. 10819.
Short changelog (from rev 10819):
- Added 3DS writer
- Sync'd with latest lib3DS
- Added options, especially "flattenMatrixTransforms" to get the "old" behaviour (else the reader correctly maps to OSG the transforms from the 3DS file).
What should be done:
- Check with pivot points, with and without "flattenMatrixTransforms" option.
- We ran tests on it, but we can never be 100% sure there is no bug. Testing from the community would of course be helpful."
fixed a small bug then:
ReaderWriterPDF.cpp, line 133, change:
std::string uri = std::string("file:") + foundFile;
to:
#if defined(WIN32) && !defined(__CYGWIN__)
std::string uri = std::string("file:///") + foundFile;
#else
std::string uri = std::string("file:") + foundFile;
#endif
That's because glib accepts "file:///C:\\data\\file.pdf" as URIs on
Windows, as well as "file:/home/data/file.pdf" on Unix, but
"file:C:\\data\\file.pdf" is not recognized.
Now I could read my Chinese translation of OSGQSG with osgpdf. :P"
and so, if the .dot plugin was loaded, it would happily handle any file
name extension.
To reproduce the bug, first save a scene to a dot file (to load the dot
plugin), then try to write the scene to an osg file. If you look at the
osg file, you will see that it is a dot file."
.dds texture files from internally-embedded textures during IVE writes."
From Robert Osfield, fixed a bug in the above submission, and changed the way that the filename of the file is passed into DataOutputStream to avoid issues with the .ive's plugins ability to read from istreams.
functionality and I also modified osgmovie example to support "seek"."
Note from Robert Osfield, changes osgmovie to use '>' for the seek as '+' was already used in a separate submission that had been merged.
then reload a video and finally delete the second XineStreamImage.
In src/osgPlugins/xine/video_out_rgb.c, many code is ASM code, and 'clear()' function is one of them.
If OSG is compiled without the flag COMPILE_ASSEMBLY (default behaviours) the clear() function is an empty
function and allocated memory is never initialized to 0. So a structure which contain pointer haven't its pointer set to NULL.
And when we need to delete this pointer, all go bad.
I join the fixed file."
being able to accurately provide the cool stuff that SVG is good for. :)
There is a one-line bug on line 68 in the
src/osgPlugins/svg/ReaderWriterSVG.cpp file where you can set the width
in the Options string, but not the height."
synchronization, improve capture device support.
here how to use it to display a capture device:
osg::Options* options = new osg::Options;
options->setPluginStringData("captureWantedWidth", "800");
options->setPluginStringData("captureWantedHeight", "600");
options->setPluginStringData("captureWantedFps", "30");
options->setPluginStringData("captureVideoDevice", "USB Video Device" );
options->setPluginStringData("captureSoundDevice", "");
then
osgDB::readImageFile("capture.directshow", options)
you can use a graphedit application to list devices available in
directshow.
for classic avi file you just need to do a
osgDB::readImageFile("file.avi.directshow");
You will need of course to install the codec needed by directshow to
read the avi files.
I recommand this tool http://avicodec.duby.info/, that check which
video/sound codec is needed to play an avi file.
You can test it with the osgmovie example.

The patched loader also complains more loudly if a material library file wasn't found or if a referenced material wasn't found in the material library."
makes smoothing optional for verticies which do not have a normal
associated with them in the OBJ input file. The previous behavior was
to always smooth at all verticies which did not have surface normals.
In this new implementation smoothing is on by default to be compatible
with previous behavior. The user can now specify the "generateFacetNormals"
option to the reader to use facet normals for verticies where the OBJ
file does not specify a normal."
Note from Robert Osfield, changed "noSmoothing" naming used by Lee to "generateFacetNormals".
Most notable the __hpux define stuff. The __hpux__ variant seems to be not
defined which resulted in a compile error at this time. Consequently I have
replaced all occurances of __hpux__ with __hpux. And huge surprise: now osg
plugins are found and loaded correctly ...
The next notable one is the MSVC_IDE fix which makes the nmake Makefiles cmake
generator target behave like the ide one. Showed up because I started to do
scripted builds with nmake instead of devenv...
The rest is the usual bunch of stuff that just happens during normal
coding ..."
I attach a modified ReaderWriterZIP.cpp (based on version 2.9.5 revision 10374).
This includes a little bit of code tidying, but the only functional change is a test of the return value of OpenZip and the addition of a call to CloseZip."
It adds new PrimitiveSet constants for the specific geometry shader primitive types :
- LINES_ADJACENCY
- LINE_STRIP_ADJACENCY
- TRIANGLES_ADJACENCY
- TRIANGLE_STRIP_ADJACENCY
It also adds some missing features to the glsl reader plug'in.
