class multicolorfits.PanelState(filepath='', data=None, header=None, stretch='linear', vmin=0.0, vmax=1.0, percent_min=0.0, percent_max=100.0, data_min=0.0, data_max=1.0, color='#FFFFFF', label='', smooth=False, smooth_sigma=3.0, in_use=False, reprojected=False)[source]#

State for one image layer (one GUI panel).

Parameters:

filepath (str)
data (ndarray | None)
header (McfHeader | None)
stretch (str)
vmin (float)
vmax (float)
percent_min (float)
percent_max (float)
data_min (float)
data_max (float)
color (str)
label (str)
smooth (bool)
smooth_sigma (float)
in_use (bool)
reprojected (bool)

filepath#

Path of the loaded FITS file, if any.

Type:: str

data, header

Image data and WCS/header after optional squeeze / reproject.

Type:: array / McfHeader

stretch, vmin, vmax

Display stretch and absolute limits for rescale_image().

Type:: str / float

percent_min, percent_max

Percentile limits (updated when the user adjusts percentile controls).

Type:: float

color, label

Layer color (hex) and optional legend label.

Type:: str

smooth, smooth_sigma

Optional Gaussian smoothing before colorize.

Type:: bool / float

in_use#

Whether this panel contributes to the combined image.

Type:: bool

reprojected#

True after the layer has been aligned off its on-disk pixel grid.

Type:: bool

Methods

`__init__`([filepath, data, header, stretch, ...])
`apply_header_string`(hdrstring)	Replace the panel header from newline-separated card text.
`apply_zscale`()	Set limits with the IRAF zscale algorithm.
`clear`()	Reset the panel to its unloaded state.
`header_string`()	The panel header serialized as newline-separated cards.
`load_fits`(filepath)	Load a FITS image into this panel.
`render_color_rgb`([gamma, inverse, dtype, ...])	Produce the colorized RGB array for this panel (the quantity that combine_multicolor consumes).
`render_display`([gamma, inverse, dtype, max_size])	Display-ready [0..1] RGB preview of this single panel (gamma-corrected; inverted single images are white-background).
`reset_minmax`()	Reset limits to the full data min/max.
`set_data`(data[, header, filepath])	Assign image data (and optional header) from arrays.
`set_limits`([vmin, vmax])	Set absolute scaling limits, updating the matching percentiles.
`set_percentiles`([pmin, pmax])	Set scaling limits from data percentiles.
`set_reprojected`(data, header)	Replace this panel's data and header with a reprojected version (from an align operation), preserving the user's display settings (stretch, color, smoothing, and absolute vmin/vmax scaling limits).
`to_dict`()
