#127 meaning of map2tga input parameters

[Anonymous]

Dear all,
I am a beginner of Healpix. I want to use map2tga to convert fits file to a tga file.
But I do not fully understand the meaning of input parameters.

map2tga <input file=""> <output file=""> [-sig <int>]</int> [-pal <int>]</int>
[-xsz <int>]</int> [-bar] [-log] [-asinh] [-lon <float>]</float> [-lat <float>]</float>
[-mul <float>]</float> [-add <float>]</float> [-min <float>]</float> [-max <float>]</float>
[-res <float>]</float> [-title <string>]</string> [-flippal] [-gnomonic]
[-interpol] [-equalize] [-viewer <viewer>]</viewer></output>

Where to find out the meaning of all parameters?

For example, I want to show latitude and longitude in a map.

Thank you very much.

Hi,

you can find a description of the parameters at https://healpix.sourceforge.io/html/Healpix_cxx/facilities.html (the other C++ command-line tools are documented there as well).
But please note that map2tga only allows fairly basic image generation ... if you need latitude/longitude indicators and similar, you should probably use healpy (https://healpy.readthedocs.io/en/latest/healpy_visu.html).
