| Here is a Perl script that does the conversion, and avoids a temp pdf file
| by using a blob.
| 
| #!/usr/bin/perl
| use warnings;
| use strict;
| use Image::Magick;
| 
| # a shell script equivalent... for comparison
| #convert -resize 99% -density 160x160 -quality 100% -compress Lossless 
lightcurve.eps lightcurve1.pdf
| #convert -quality 100% -compress Lossless lightcurve1.pdf lightcurve1.png
| #convert lightcurve1.png -trim lightcurve2.png
| #convert -bordercolor SkyBlue -border 40x40 lightcurve2.png  lightcurve3.png
| 
| my $img = Image::Magick->new;
| $img->Read('lightcurve.eps');
| $img->Resize('101%');  #needed hack for portrait/landscape conversion
| $img->set('quality'=> 100, );
| $img->set('compresion'=> 'LosslessJPEG' );
| #$img->Write(filename=>'zzimage.pdf'); #works good when written to temp file
| # but using an inline blob here to avoid a temp file
| $img->set('magick'=>'pdf');
| my $blob = $img->ImageToBlob();
| 
| #and the opposite
| my $img1 = Image::Magick->new(magick=>'pdf');
| $img1->BlobToImage( $blob );
| $img1->set('quality'=> 100, );
| $img1->set('compresion'=> 'LosslessJPEG' );
| 
| #add a border
| $img1->Border('bordercolor' => 'SkyBlue','width'=>40,'height'=>40);
| 
| $img1->Write(filename=>'zzzimage.jpg');
| $img1->Write(filename=>'zzzimage.png');
|
