# PDF::Class
This Raku module is the base class for [PDF::API6](https://pdf-raku.github.io/PDF-API6).
PDF::Class provides a set of roles and classes that map to the internal structure of PDF documents; the aim being to make it easier to read, write valid PDF files.
It assists with the construction of PDF documents, providing type-checking and the sometimes finicky serialization rules regarding objects.
## Description
The entry point of a PDF document is the trailer dictionary. This is mapped to `PDF::Class`. It contains a `Root` entry which is mapped to a `PDF::Catalog` objects, and may contain other entries, including an `Info` entry mapped to a `PDF::Info` object.
```
use PDF::Class;
use PDF::Catalog;
use PDF::Page;
use PDF::Info;
my PDF::Class $pdf .= open: "t/helloworld.pdf";
# vivify Info entry; set title
given $pdf.Info //= {} -> PDF::Info $_ {
.Title = 'Hello World!';
.ModDate = DateTime.now; # PDF::Class sets this anyway...
}
# modify Viewer Preferences
my PDF::Catalog $catalog = $pdf.Root;
given $catalog.ViewerPreferences //= {} {
.HideToolbar = True;
}
# add a page ...
my PDF::Page $new-page = $pdf.add-page;
$new-page.gfx.say: "New last page!";
# save the updated pdf
$pdf.save-as: "tmp/pdf-updated.pdf";
```
- This module contains definitions for many other standard PDF objects, such as Pages, Fonts and Images, as listed below.
- There is generally a one-to-one correspondence between raw dictionary entries and accessors, e.g. `$pdf<Root><AA>` versus `$pdf.Root.AA`.
- There are often accessor aliases, to aide clarity. E.g. `$pdf.Root.AA` can also be written as `$pdf.catalog.additional-actions`.
- The classes often contain additional accessor and helper methods. For example `$pdf.page(10)` - references page 10, without the need to navigate the catalog and page tree.
This module is a work in progress. It currently defines roles and classes for many of the more commonly occurring PDF objects as described in the [PDF 32000-1:2008 1.7](http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf) specification.
## More examples:
### Set Marked Info options
```
use PDF::Class;
use PDF::Catalog;
use PDF::MarkInfo;
my PDF::Class $pdf .= new;
my PDF::Catalog $catalog = $pdf.catalog; # same as $pdf.Root;
with $catalog.MarkInfo //= {} -> PDF::MarkInfo $_ {
.Marked = True;
.UserProperties = False;
.Suspects = False;
}
```
### Set Page Layout & Viewer Preferences
```
use PDF::Class;
use PDF::Catalog;
use PDF::Viewer::Preferences;
my PDF::Class $pdf .= new;
my PDF::Catalog $doc = $pdf.catalog;
$doc.PageLayout = 'TwoColumnLeft';
$doc.PageMode = 'UseThumbs';
given $doc.ViewerPreferences //= {} -> PDF::Viewer::Preferences $_ {
.Duplex = 'DuplexFlipShortEdge';
.NonFullScreenPageMode = 'UseOutlines';
}
# ...etc, see PDF::ViewerPreferences
```
### List AcroForm Fields
```
use PDF::Class;
use PDF::AcroForm;
use PDF::Field;
my PDF::Class $doc .= open: "t/pdf/samples/OoPdfFormExample.pdf";
with my PDF::AcroForm $acroform = $doc.catalog.AcroForm {
my PDF::Field @fields = $acroform.fields;
# display field names and values
for @fields -> $field {
say "{$field.key}: {$field.value}";
}
}
```
## Gradual Typing
In theory, we should always be able to use PDF::Class accessors for structured access and updating of PDF objects.
In reality, a fair percentage of PDF files contain at least some conformance issues (as reported by `pdf-checker.raku`) and PDF::Class itself
is under development.
For these reasons it possible to bypass PDF::Class accessors; instead accessing hashes and arrays directly, giving raw access to the PDF data.
This will also bypass type coercements, so you may need to be more explicit. In
the following example forces the setting of PageMode to an illegal value.
```
use PDF::Class;
use PDF::Catalog;
use PDF::COS::Name;
my PDF::Class $pdf .= new;
my PDF::Catalog $doc = $pdf.catalog;
try {
$doc.PageMode = 'UseToes'; # illegal
CATCH { default { say "err, that didn't work: $_" } }
}
# same again, bypassing type checking
$doc<PageMode> = PDF::COS::Name.COERCE: 'UseToes';
```
## Scripts in this Distribution
#### `pdf-append.raku --save-as=output.pdf in1.pdf in2.pdf ...`
appends PDF files.
#### `pdf-burst.raku --save-as=basename-%03d.pdf --password=pass in.pdf`
bursts a multi-page PDF into single page PDF files
#### `pdf-checker.raku --trace --render --strict --exclude=Entry1,Entry2 --repair input-pdf`
This is a low-level tool for PDF authors and users. It traverses a PDF, checking it's internal structure against
PDF:Class definitions as derived from the [PDF 32000-1:2008 1.7](http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf) specification.
- `--trace` print a dump of PDF Objects as the file is traversed
- `--render` also render and check the contents of graphical objects, such as Pages and XObject forms
- `--strict` perform additional checks:
- `--repair` repair PDF before Checking
#### Example 1: Dump a simple PDF
% pdf-checker.raku --trace t/helloworld.pdf
xref: << /ID ... /Info 1 0 R /Root 2 0 R >> % PDF::Class
/ID: [ "×C¨\x[86]üÜø\{iÃeH!\x[9E]©A" "×C¨\x[86]üÜø\{iÃeH!\x[9E]©A" ] % PDF::COS::Array[Str]

Checking of t/helloworld.pdf completed with 0 warnings and 0 errors
This example dumps a PDF and shows how PDF::Class has interpreted it.
- indirect object `1 0 R` is a dictionary that has had the `PDF::Info` role applied
- indirect object `2 0 R` has been loaded as a `PDF::Catalog` object.
- font `/F3` is a ZapfDingbats type1 font
The PDF contains has one page (PDF::Page) that references various other objects, such as fonts and
xobject images.
#### Example 2: Check a sample PDF
% wget http://www.stillhq.com/pdfdb/000025/data.pdf
% pdf-checker.raku --strict --render data.pdf
Warning: Error processing indirect object 27 0 R at byte offset 976986:
Ignoring 1 bytes before 'endstream' marker
Rendering warning(s) in 28 0 R (PDF::Page):
-- unexpected operation 'w' (SetLineWidth) used in Path context, following 'm' (MoveTo)
-- unexpected operation 'w' (SetLineWidth) used in Path context, following 'm' (MoveTo)
Rendering warning(s) in 30 0 R (PDF::XObject::Form):
-- unexpected operation 'w' (SetLineWidth) used in Path context, following 'm' (MoveTo)
Unknown entries 1 0 R (PDF::Catalog) struct: /ViewPreferences(?ViewerPreferences)
Checking of /home/david/Documents/test-pdf/000025.pdf completed with 5 warnings and 0 errors
In this example:
- Object `28 0 R` had an extra byte in its stream data.
- Some Page and XObject graphics operations were not in the
expected order, (as outlined in PDF 32000 Figure 9 – Graphics Objects).
- The Catalog dictionary had an unexpected `/ViewPreferences`
entry (It should be `/ViewerPreferences`, see PDF::Catalog).
##### Notes
- A message such as `No handler class PDF::Filespec`, usually indicates the the object has not yet been implemented in PDF::Class.
#### `pdf-content-dump.raku --raku in.pdf`
Displays the content streams for PDF pages, commented,
and in a human-readable format:
% pdf-content-dump.raku t/example.pdf
% **** Page 1 ****
BT % BeginText
1 0 0 1 100 150 Tm % SetTextMatrix
/F1 16 Tf % SetFont
17.6 TL % SetTextLeading
[ (Hello, world!) ] TJ % ShowSpaceText
T* % TextNextLine
ET % EndText
The `--raku` option dumps using a Raku-like notation:
pdf-content-dump.raku --perl t/example.pdf
# **** Page 1 ****
.BeginText();
.SetTextMatrix(1, 0, 0, 1, 100, 150);
.SetFont("F1", 16);
.SetTextLeading(17.6);
.ShowSpaceText($["Hello, world!"]);
.TextNextLine();
.EndText();
#### `pdf-info.raku in.pdf`
Prints various PDF properties. For example:
% pdf-info.raku ~/Documents/test-pdfs/stillhq.com/000056.pdf

## Development Status
The PDF::Class module is under construction and not yet functionally complete.
Note: The roles and classes in this module are primarly based on roles generated by the PDF::ISO_32000 module.
The PDF::class module currently implements around 100 roles and classes of the 350+ objects extracted by PDF::ISO_32000.
