_D_e_s_c_r_i_p_t_i_o_n:

     Creates a new pixbuf by loading an image from a file.  The file
     format is detected automatically. If 'NULL' is returned, then
     'error' will be set. Possible errors are in the 'GDK_PIXBUF_ERROR'
     and 'G_FILE_ERROR' domains. The image will be scaled to fit in the
     requested size, optionally preserving the image's aspect ratio.

_U_s_a_g_e:

     gdkPixbufNewFromFileAtScale(filename, width, height, preserve.aspect.ratio, .errwarn = TRUE)

_A_r_g_u_m_e_n_t_s:

'filename': [char]  Name of file to load, in the GLib file name
          encoding

 'width': [integer]  The width the image should have or -1 to not
          constrain the width

'height': [integer]  The height the image should have or -1 to not
          constrain the height

'preserve.aspect.ratio': [logical] 'TRUE' to preserve the image's
          aspect ratio

.errwarn: Whether to issue a warning on error or fail silently

_D_e_t_a_i_l_s:

     When preserving the aspect ratio, a 'width' of -1 will cause the
     image to be scaled to the exact given height, and a 'height' of -1
     will cause the image to be scaled to the exact given width. When
     not preserving aspect ratio, a 'width' or 'height' of -1 means to
     not scale the image  at all in that dimension. Negative values for
     'width' and 'height' are  allowed since 2.8.  

     Since  2.6

_V_a_l_u_e:

     A list containing the following elements: 

  retval: ['GdkPixbuf']  A newly-created pixbuf with a reference count
          of 1, or 'NULL'  if any of several error conditions occurred:
           the file could not be opened, there was no loader for the
          file's format, there was not enough memory to allocate the
          image buffer, or the image file contained invalid data.

 'error': ['GError']  Return location for an error

_A_u_t_h_o_r(_s):
