Hello

You can use TextureIO to create a TextureData instance but Texture uses only GL.GL_TEXTURE_2D and GL2.GL_TEXTURE_RECTANGLE_ARB as texture targets. You can pass the pixels of a TextureData instance returned by getBuffer() to glTexSubImage3D.

Our PNG loader uses PNGJ under the hood, it should work except if you use an unsupported PNG format.
