Parameters ---------- filename : str The filename of the FITS file. ext : int FITS extension name or number of the image to convert. The default is 0. out_fn : str The filename of the output bitmap image. The type of bitmap is determined by the filename extension (e.g. '.jpg', '.png'). The default is a PNG file with the same name as the FITS file. stretch : {{'linear', 'sqrt', 'power', log', 'asinh'}} The stretching function to apply to the image. The default is 'linear'. power : float, optional The power index for ``stretch='power'``. The default is 1.0. asinh_a : float, optional For ``stretch='asinh'``, the value where the asinh curve transitions from linear to logarithmic behavior, expressed as a fraction of the normalized image. Must be in the range between 0 and 1. The default is 0.1. min_cut : float, optional The pixel value of the minimum cut level. Data values less than ``min_cut`` will set to ``min_cut`` before stretching the image. The default is the image minimum. ``min_cut`` overrides ``min_percent``. max_cut : float, optional The pixel value of the maximum cut level. Data values greater than ``min_cut`` will set to ``min_cut`` before stretching the image. The default is the image maximum. ``max_cut`` overrides ``max_percent``. min_percent : float, optional The percentile value used to determine the pixel value of minimum cut level. The default is 0.0. ``min_percent`` overrides ``percent``. max_percent : float, optional The percentile value used to determine the pixel value of maximum cut level. The default is 100.0. ``max_percent`` overrides ``percent``. percent : float, optional The percentage of the image values used to determine the pixel values of the minimum and maximum cut levels. The lower cut level will set at the ``(100 - percent) / 2`` percentile, while the upper cut level will be set at the ``(100 + percent) / 2`` percentile. The default is 100.0. ``percent`` is ignored if either ``min_percent`` or ``max_percent`` is input. cmap : str The matplotlib color map name. The default is 'Greys_r'. iNiiu,data in FITS extension {0} is not a 2D arrayu.fitsu.pngupngu2.0.0iÿÿÿÿu,{0} is not a valid matplotlib colormap name.tstretchtpowertasinh_atmin_cuttmax_cutt min_percentt max_percenttpercenttcmaptoriginulowertformatuSaved file to {0}.(t matplotlibt matplotlib.cmtcmtmatplotlib.imagetimagetintt ValueErrorRt ExceptionRtcriticaltndimRtNonetostpathtsplitexttendswithtlowerRt __version__tdatadRtimsavetinfo(tfilenametexttout_fnRR R R R R RRRRRtmimgRtet out_formattnorm((sHlib/python2.7/site-packages/astropy/visualization/scripts/fits2bitmap.pyt fits2bitmap sF;            !cC`s/ddl}|jddƒ}|jddddddd d ƒ|jd dd d tddd dƒ|jdd tddd dƒ|jdd tddd dƒ|jdd tddd dƒ|jdd tddd dƒ|jdd tddd dƒ|jdd tddd dƒ|jdd tddd dƒ|jd d tddd d!ƒ|jd"dd#d tdd$d d%ƒ|jd d&d'd d(ƒ|j|ƒ}x~|jD]s}t|d)|j d*|j d+|j d,|j d-|j d.|jd/|jd0|jd1|jd2|jd3|jƒ q´WdS(4Nit descriptionu'Create a bitmap file from a FITS image.u-eu--exttmetavaruhdutdefaultthelpu8Specify the HDU extension number or name (Default is 0).u-oufilenamettypeuZFilename for the output image (Default is a PNG file with the same name as the FITS file).u --stretchulinearu^Type of image stretching ("linear", "sqrt", "power", "log", or "asinh") (Default is "linear").u--powergð?u4Power index for "power" stretching (Default is 1.0).u --asinh_agš™™™™™¹?u•The value in normalized image where the asinh curve transitions from linear to logarithmic behavior (used only for "asinh" stretch) (Default is 0.1).u --min_cutuHThe pixel value of the minimum cut level (Default is the image minimum).u --max_cutuHThe pixel value of the maximum cut level (Default is the image maximum).u --min_percentuLThe percentile value used to determine the minimum cut level (Default is 0).u --max_percentuNThe percentile value used to determine the maximum cut level (Default is 100).u --percentu}The percentage of the image values used to determine the pixel values of the minimum and maximum cut levels (Default is 100).u--cmapu colormap_nameuGreys_ru1matplotlib color map name (Default is "Greys_r").tnargsu+u)Path to one or more FITS files to convertR(R)RR R R RRR R R(targparsetArgumentParsert add_argumenttstrRtfloatt parse_argsR'R.R(toRR R R RRR R R(targsR5tparserR'((sHlib/python2.7/site-packages/astropy/visualization/scripts/fits2bitmap.pytmain{sD    (t __future__RRRRRtdistutils.versionRt mpl_normalizeRtRtio.fitsRRR.R>(((sHlib/python2.7/site-packages/astropy/visualization/scripts/fits2bitmap.pyts"     k
