Hi Geoff,I don't believe that OSG enforces any type of image size limit. I suspect that your computer is simply running out of memory trying to allocate that much contiguous memory (over 5 GB for that image).
The good news is that OSG does have a framework in place that can help you handle and display large images. I don't know much about how it works, but I believe that osg::PagedLOD is involved somehow.

Hi,
I am currently working on creating a poster image from several images and the
file size is pretty large. Currently the one I am trying to create is 65250
wide x 22500 pixels in height (Image needs to be large)
Currently I am doing the following:
Code:
posterImage = new osg::Image;
posterImage->allocateImage( (mHeight), (mWidth), 1, GL_RGBA,
GL_UNSIGNED_BYTE );
Right now it is giving me an exception when trying to allocate that image. Is
there a size limit on it, or am I doing something wrong?
...
Thank you!
Cheers,
Geoff
