utils/healpix.py: Fix the import issue

2016-11-09T15:37:09+00:00

utils/init.py: Only import "setup_logging" from "logging.py"

2016-10-29T15:10:40+00:00

Since some modules (e.g., healpix.py) under "utils" involves Numba JIT
optimization, which significantly slows the start-up speed, even some
consumers (e.g., bin/fg21sim-webui) do not need them at all.

Fix various import statements of other modules.

NOTE: not test at the moment!

utils/random.py: Add a note on conversion to (longitude, latitude)

2016-10-28T13:39:18+00:00

utils/rotate.py: Add a new ref. which may help further vectorization

2016-10-28T13:37:40+00:00

Investigate whether the vectorization will improve the speed.

utils/fits.py: Add parameter "checksum" for write_fits_healpix()

2016-10-27T03:12:01+00:00

Also update the docstring and one comment.

utils/rotate.py: Fix two bugs which cause wrong results

2016-10-26T12:35:16+00:00

* Fix the wrong output shape: wrongly swap the row and column
* Fix the area mapping method, which may give zero values when the index
  of the input is integer, which cause problem to calculate the
  overlapping areas.

utils/grid.py: JIT optimize "make_grid_ellipse()"

2016-10-26T07:50:19+00:00

NOTE that the original optional paramter "rotation" is now required.

utils/grid.py: Use own-implemented JIT-optimized "rotate_center()"

2016-10-26T07:36:57+00:00

Also remove the dependence on "scipy".

Add utils/rotate.py: Implement basic image rotation

2016-10-26T07:33:28+00:00

The "rotate_center()" function rotates a gray-scale image by a given
angle about its center, using the area mapping method or simple nearest
neighbor.

This function is `numba` JIT-optimized, and can replace the
`scipy.ndimage.rotate()` function.

draw.py: Remove the unused "circle()" function

2016-10-25T15:34:18+00:00
