它们都是可行的选择。
我发现 wkhtmltopdf 太耗费资源且速度太慢。如果您确实想走这条路,那么已经有现有的 html 模板可以通过快速google search 找到。
PDF::API2 性能非常好,我在服务器系统上运行它没有任何问题。这是我用于以网格格式布置元素的示例脚本;
#!/usr/bin/env perl
use strict 'vars';
use FindBin;
use PDF::API2;
# Min usage, expects bank.pdf to exist in same location
render_grid_pdf(
labels => ['One', 'Two', 'Three', 'Four'],
cell_width => 200,
cell_height => 50,
no_of_columns => 2,
no_of_rows => 2,
);
# Advanced usage
render_grid_pdf(
labels => ['One', 'Two', 'Three', 'Four'],
cell_width => 200,
cell_height => 50,
no_of_columns => 2,
no_of_rows => 2,
font_name => "Helvetica-Bold",
font_size => 12,
template => "blank.pdf",
save_as => "my_labels.pdf",
# Manually set coordinates to start prinding
page_offset_x => 20, # Acts as a left margin
page_offset_y => 600,
);
sub render_grid_pdf {
my %args = @_;
# Print data
my $labels = $args{labels} || die "Labels required";

# Note: PDF::API2 uses cartesion coordinates, 0,0 being

# reference to top-left to make things easier to manage
my $page_offset_x = $args{page_offset_x} || 0;
my $page_offset_y = $args{page_offset_y} || $no_of_rows * $cell_height;
# Open an existing PDF file as a templata
my $pdf = PDF::API2->open("$template");

my $font = $pdf->corefont($font_name);
my $page = $pdf->openpage(1);

# Exit condition
if ( $current_label > scalar @{$labels}) {

}
}
}
# Save the PDF
$pdf->saveas($save_as);
