PDL::Graphics::X::Fits
OO X Windows fits image display

PDL::Graphics::X::Fits - OO X Windows fits image display


NAME

PDL::Graphics::X::Fits - OO X Windows fits image display


SYNOPSIS


  use PDL;

  use PDL::Graphics::LUT;

  use PDL::Graphics::X::Fits;

  my $fits = rfits("PDL-2.4.1/m51.fits");

  my $win1 = PDL::Graphics::X::Fits->new($fits, {WIN_TITLE => "In Color", CTAB => cat(lut_data("idl5"))});

  my ($x, $y) = $win1->cursor();


DESCRIPTION

A OO X Windows fits image display module built on PDL::Graphics::X. This module draws fits image with appropriately labeled axises & tick marks, similar to those drawn by PGPLOT. Once the image has been displayed, the cursor method will return the location of the next mouse click in image coordinates.

Options recognized


       CTAB - color table to use when displaying the image (greyscale is default)

        MIN - minimum value to display (image minimum is default)

        MAX - maximum value to display (image maximum is default)

        RGB - set to 1 to display a RGB fits (expects the image to be in the form (x, y, RGB))

  WIN_TITLE - a title for the window (default is "X::FITS")

EXPORT

None by default.

KNOWN ISSUES

Since PDL::Graphics::X doesn't handle rotated text very well, the y-axis label looks pretty ugly.
