TVMask
======
Display masks from file (non-interative mode) on an image.
Plugin Type: Local
------------------
TVMask is a local plugin, which means it is associated with a
channel. An instance can be opened for each channel.
Usage
-----
This plugin allows non-interactive display of mask by reading in a FITS
file, where non-zero is assumed to be masked data.
To display different masks (e.g., some masked as green and some as pink, as
shown above):
1. Select green from the drop-down menu. Alternately, enter desired alpha value.
2. Using "Load Mask" button, load the relevant FITS file.
3. Repeat Step 1 but now select pink from the drop-down menu.
4. Repeat Step 2 but choose another FITS file.
5. To display a third mask as pink too, repeat Step 4 without changing the
drop-down menu.
Selecting an entry (or multiple entries) from the table listing will
highlight the mask(s) on the image. The highlight uses a pre-defined color and
alpha (customizable below). Clicking on a masked pixel will highlight the
mask(s) both on the image and the table listing.
You can also highlight all the masks within a region both on the image
and the table listing by drawing a rectangle on the image using the right mouse
button while this plugin is active.
Pressing the "Hide" button will hide the masks but does not clear the
plugin's memory; That is, when you press "Show", the same masks will
reappear on the same image. However, pressing "Forget" will clear the masks
both from display and memory; That is, you will need to reload your file(s) to
recreate the masks.
To redraw the same masks with different color or alpha, press "Forget"
and repeat the steps above, as necessary.
If images of very different pointings/dimensions are displayed in the same
channel, masks that belong to one image but fall outside another will not
appear in the latter.
To create a mask that this plugin can read, one can use results from
the `Drawing` plugin (press "Create Mask" after drawing and save the
mask using `SaveImage`), in addition to creating a FITS
file by hand using `astropy.io.fits`, etc.
Used together with `TVMark`, you can overlay both point sources and
masked regions in Ginga.
