* utils/draw.py: Replace "ellipse()" with the `skiimage' versionAaron LI2017-08-311-27/+96
| | | | | | | Also do not use Numba JIT here. Credit: scikit-image - skimage/draw/draw.py https://github.com/scikit-image/scikit-image/blob/master/skimage/draw/draw.py
* utils/draw.py: Add function circle()Aaron LI2017-07-181-1/+62
| | | | | | Draw a circle at the center of the output grid with radial profile Signed-off-by: Aaron LI <aly@aaronly.me>
* utils/draw.py: Merge "_ellipse_in_shape()" to "ellipse()"Aaron LI2016-12-131-84/+24
| | | | | * Fix the bug that "ellipse()" generate unexpected results. * Update the parameters of "ellipse()" also
* utils/draw.py: Fix a wrong brace in "_ellipse_in_shape()"Aaron LI2016-12-131-1/+1
| | | | | This bug causes wrong ellipse generation, which is the main reason to the strange and wrong SNRs shapes.
* utils/draw.py: Remove the "Modified BSD" license; Update creditAaron LI2016-11-181-40/+4

* draw.py: Remove the unused "circle()" functionAaron LI2016-10-251-42/+0

* draw.py: Optimize "ellipse()" using numba JITAaron LI2016-10-251-17/+27
| | | | | | | | | | NOTE: However, there are two significant problems: * Cannot figure out why ``nb.optional(nb.types.UniTuple(nb.int64, 2))`` does NOT work. Therefore, make ``shape`` as mandatory parameter instead of optional. * Cannot figure out multi-dispatch that allows both int and float types for ``r``, ``c``, ``r_radius`` and ``c_radius``. Thus only support the int type for the moment.

* Add utils/draw.py: draw circles and ellipsesAaron LI2016-10-151-0/+128
These functions will be used to draw the image of a SNR or a radio halo. These functions are copied from the `scikit-image` project. Thanks! scikit-image: http://scikit-image.org/docs/dev/api/skimage.draw.html
