FITS2BITMAP(1)

✨ NAME ✨

fits2bitmap — bestie, this makes a bitmap file out of a FITS image. that's it, that's the whole job 💅

🌸 DESCRIPTION 🌸

okay so here's the vibe. you got a FITS image (astronomy data, iconic), and you want a cute lil picture out of it. that's literally what this does. here's how you call it:

usage: fits2bitmap [-h] [-e hdu] [-o filename] [--scale SCALE] [--power
POWER]

       [--asinh_a ASINH_A] [--min_cut MIN_CUT] [--max_cut MAX_CUT]
       [--min_percent MIN_PERCENT] [--max_percent MAX_PERCENT]
       [--percent PERCENT] [--cmap colormap_name] filename [filename
       ...]

like yes it's a lot of brackets, breathe, we'll get through it together 🫶

🎀 positional arguments 🎀

• filename — the path to one or more FITS files you wanna convert. yes, more than one, she's flexible ✨

💜 optional arguments 💜

• -h, --help — shows you this help message and dips. classic.
• -e hdu, --ext hdu — tells it which HDU extension number or name to use. (HDU = header data unit, iykyk)
• -o filename — the filename for the output image. the default? a PNG file with the exact same name as the FITS file. lowkey convenient.
• --scale SCALE — the type of image scaling. your options are "linear", "sqrt", "power", "log", or "asinh". pick your fighter.
• --power POWER — the power index, and this one's only for "power" scaling. no cap.
• --asinh_a ASINH_A — the value in the normalized image where the asinh curve transitions from linear to logarithmic behavior. only used for "asinh" scaling, so don't stress about it otherwise 🧚
• --min_cut MIN_CUT — the pixel value of the minimum cut level.
• --max_cut MAX_CUT — the pixel value of the maximum cut level.
• --min_percent MIN_PERCENT — the percentile value used to determine the minimum cut level.
• --max_percent MAX_PERCENT — the percentile value used to determine the maximum cut level.
• --percent PERCENT — the percentage of the image values used to determine the pixel values of the minimum and maximum cut levels.
• --cmap colormap_name — the matplotlib color map name. go wild, she's giving aesthetic 🌈

fr fr, that's every single flag. nothing hiding. no secret menu 💖

this whole thing is brought to you by astropy 1.0.2, dated April 2015, and it's literally called fits2bitmap. ok that's the whole page, you ate, go make some bitmaps bestie 👑💅
