Generate pseudo-star images with given Moffat parameters at given coordinates xi,yi (with amplitude ampi, ampi < 256). Also draw different primitives and text.

Usage: genu16 [args] x1,y1[,w1] x2,y2[,w2] ... xn,yn[,w3] - draw 'stars' at coords xi,yi with weight wi (default: 1.)

    Where args are:

-?, --help show this help -b, --beta=arg beta Moffat parameter of 'star' images (default: 1) -h, --height=arg resulting image height (default: 1024) -i, --input=arg input file with coordinates and amplitudes (comma separated) -l, --lambda=arg lambda of Poisson noice (default: 10) -o, --output=arg output file name (default: output.jpg) -s, --halfwidth=arg FWHM of 'star' images (default: 3.5) -w, --width=arg resulting image width (default: 1024)

genu16

The same as 'generate', but works with 16-bit image and save it as 1-channel png (ampi now is weight). No noice.

gauss

Simulator of falling photons with given gaussian distribution.

Usage: gauss [args], where args are:

-?, --help show this help -X, --xstd=arg STD of 'photons' distribution by X (default: 10) -Y, --ystd=arg STD of 'photons' distribution by Y (default: 10) -h, --height=arg resulting image height (default: 1024) -n, --niter=arg iterations ("falling photons") number (default: 1000000) -o, --output=arg output file name (default: output.png) -w, --width=arg resulting image width (default: 1024) -x, --xcenter=arg X coordinate of 'image' center (default: 512) -y, --ycenter=arg Y coordinate of 'image' center (default: 512)

poisson

Add poisson noice to every pixel of image.

-?, --help show this help -h, --height=arg resulting image height (default: 1024) -l, --lambda=arg mean (and dispersion) of distribution (default: 15.) -o, --output=arg output file name (default: output.png) -w, --width=arg resulting image width (default: 1024)
