Re: [osg-users] Allocating osg::image from my own data buffer

[Robert Osfield]

HI Bruno,

Simply clone the image i.e.

  osg::ref_ptr iimag_copy = osg::clone(img);

The osg::Image will copy the internal image data without attempting to
share it, and will own it's own local copy of the data and delete it
automatically when img_copy is deleted (ref count goes to 0.)

[osg-users] Allocating osg::image from my own data buffer

[Bruno Oliveira]

Hello,

the following code block is creating an image from a buffer I own. This
does not allocate a new buffer, but assumes my buffer will not be
deallocated. How do I create a new, independent osg::Image copying data
from my buffer to an internal array?

osg::Image img = osg::image();
img->setImage(
  width,
  height,
  1,
  internalTextureFormat(),
  type(),
  MyDataBuffer(),
  osg::Image::NO_DELETE);
