image.insert - Function
1.1.1 Insert specified image into this image
Description
This function inserts the specified image (or part of it) into the image
referenced by this tool. The specified image may be given via argument
infile as a disk file name (it may be in native CASA, FITS, or Miriad format;
Look ?? for more information on foreign images).
If the locate vector is not given, then the images are aligned (to an integer pixel shift) by their reference pixels.
If locate vector is given, then those values that are given, give the absolute pixel in the output (this) image of the bottom left corner of the input (sub)image. For those values that are not given, the input image is symmetrically placed in the output image.
The image referenced by this tool is modified in place; no new image is created. The method returns True if successful.
