Hi,
instead of the magic "3" in your setImage, try "GL_RGB".
E.g. we have some code like this:
->setImage(ImageFormat_.getWidth(), ImageFormat_.getHeight(), 1,
GL_RGB, GL_RGB, GL_UNSIGNED_BYTE,
&(im->Data_[0]),
osg::Image::NO_DELETE)

Dear All,
I am using openCV and OSG together in my project. What the problem is as
follows:
1) When I try to convert the IplImage to osg::Image the following
command line trace occurs. Except the last three lines, the trace shows
the openCV and osg image properties.
Pixel Bits: 32, Image Size (Byte): 307200
Video Depth: 1
cv Channels = 3
Convert_OpenCV_to_OSG_IMAGE()::Origin Passed 2...
Mutex w/r : 0
error pixelFormat = error pixelFormat = 33
Warning: detected OpenGL error 'invalid operation' after RenderBin::draw(,)
Warning: detected OpenGL error 'invalid operation' after RenderBin::draw(,)
2) I lock the mutex in order to prevent simultaneous writes to
osg::Image data and as you can see at 5th line above it returns the
correct value 0. Then use the following code:
void Convert_OpenCV_to_OSG_IMAGE(IplImage* cvImg, osg::Image* osgImg)
{
//.....
osgImg->setImage(cvImg->width,
cvImg->height,
1,
3,
GL_RGB,
GL_UNSIGNED_BYTE,
(unsigned char*)(cvImg->imageData),
osg::Image::AllocationMode::NO_DELETE,
1);
//.....
}
The above code segment is similar to the one in a post I encountered in
this forum (*John Steinbis* jsteinbis at gmail.com
<mailto:osg-users%40lists.openscenegraph.org?Subject=%5Bosg-users%5D%20Convertion%20to%20osg%3A%3AImage%20from%20IplImage%20%28OpenCV%29%20for%0A%09useas%20texture&In-Reply-To=E4D07AB09F5F044299333C8D0FEB45E9042314AE%40nrccenexb1.nrc.ca>
/Mon Sep 17 11:04:04 PDT 2007/) but there are modifications for my
needs. I can be sure that cvImg->imageData contains the actual processed
video data because I can see the results in a seperate window. But the
above problem occurs when I try to render the processed video as a
texture onto a surface.
3) The above function Convert_OpenCV_to_OSG_IMAGE() is called in the
main loop as follows:
while(!viewer.done())
{
//.....
getPixelBufferObject()->setImage(Convert_OpenCV_to_OSG_IMAGE(pImage,
((osg::Image*)(video.get()))));
//.....
}
What might be the problem? When I disable the code segment
osgImg->setImage(cvImg->width,
cvImg->height,
1,
3,
GL_RGB,
GL_UNSIGNED_BYTE,
(unsigned char*)(cvImg->imageData),
osg::Image::AllocationMode::NO_DELETE,
1);
everything is OK but as you can guess I cannot use the processed frame
as a texture in 3D environment.
Thanks for your helps...
Best Regards
Ugras Erdogan
