Package gmisclib :: Module g_ds9

Module g_ds9

Handles interactions with ds9 (http://hea-www.harvard.edu/RD/ds9/). Ds9 is an image display and analysis tool commonly used in astrophysics, but it's good for any kind of greyscale image.

Note: there is an extra, special property Coordsys. This is not fed to ds9. It is merely something that you can use to remember what coordinate system the regions are in.

Classes
	UnknownProperty
	execwait
	ds9_io
	BadTagError
	Region
	line
	circle
	point
	text
	ds9
	ds9_file This is just a convenient way to write regions to a file, instead of writing them to a ds9 session.

Function Details

copy(r, **kwargs)

source code

Copy a region and update some of the keyword arguments (e.g. color). The original object is unchanged, and you can copy any subclass of Region.

read_regions_iter(fd, Coordsys=None)

source code

Read regions from a file. This is an iterator. Fd is a file descriptor.

read_regions(fd, Coordsys=None)

source code

Read regions from a file. Fd is a file descriptor.
