Implementations

impl Args

pub fn validate_projection_args(&self) -> Result<(), String>

Validate that projection-specific arguments are only used with their respective projection

pub fn resolve_config(&self) -> Result<PlotConfig, String>

pub fn get_output_filename(&self) -> String

Determine output filename from –out flag or input FITS filename.

Logic

1. If –out is explicitly provided, use it
2. If input FITS file is provided, use it with .fits → .pdf extension
3. If neither, use “map2fig_test.pdf” as fallback

pub fn describe_coord_transform(&self) -> Option<String>

Check if coordinate transformation is needed.

Returns Some(from_to_string) if input_coord != output_coord

pub fn resolve_view_transform(&self) -> Result<ViewTransform, String>
