I think there is an issue in Image::readPixels that I noted in 2.8.x Assume you have set the Image "packing" is set to say 4 , via image->setPacking(4) before this call. glReadPixels might try and store 'too much' data into _data ( overwriting memory) because glReadPixels will be expecting the pixel data is using a packing of 4 but allocateImage was passed a "packing" of 1 via the default parameter.
It certainly cause my code to crash depending on the variations of width and height. void Image::readPixels(int x,int y,int width,int height, GLenum format,GLenum type) { allocateImage(width,height,1,format,type); glPixelStorei(GL_PACK_ALIGNMENT,_packing); glReadPixels(x,y,width,height,format,type,_data); } changing code to allocateImage(width,height,1,format,type,_packing); seems to fix the issue. It's pretty subtle, and may only affect some people who need a particular format for the image data, and maybe calling setPacking is an abuse of the API so this can be seen as informational only rather than a 'bug' report. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=46637#46637 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
