# PDF::Class 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. This is the base class for [PDF::API6](https://github.com/p6-pdf/PDF-API6). ## Description The top level of a PDF document is of type `PDF::Class`, which corresponds to the trailer dictionary. It may contain several entries including `PDF::Info` metadata in the 'Info' entry and `PDF::Catalog` in the `Root` entry. ``` 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 $pdf.save-as: "tmp/pdf-updated.pdf", :!info; ``` - This module contains definitions for many other standard PDF objects, such as Pages, Fonts and Images, as listed below. - There is generally a one-to-one correspondence between raw dictionary entries and accessors, e.g. `$pdf` 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; my PDF::Class $pdf .= new; my PDF::Catalog $catalog = $pdf.catalog; # same as $pdf.Root; with $catalog.MarkInfo //= {} { .Marked = True; .UserProperties = False; .Suspects = False; } ``` ### Set Page Layout & Viewer Preferences ``` use PDF::Class; use PDF::Catalog; my PDF::Class $pdf .= new; my PDF::Catalog $doc = $pdf.catalog; $doc.PageLayout = 'TwoColumnLeft'; $doc.PageMode = 'UseThumbs'; given $doc.ViewerPreferences //= {} { .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 we cast the PageMode to a name, so it appears as a name in the out put stream `:name`, rather than a string `'UseToes'`. ``` use PDF::Class; use PDF::Catalog; my PDF::Class $pdf .= new; my PDF::Catalog $doc = $pdf.catalog; try { $doc.PageMode = 'UseToes'; CATCH { default { say "err, that didn't work: $_" } } } # same again, bypassing type checking $doc = :name; ``` ## 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] /Info: << /Author "t/helloworld.t" /CreationDate (D:20151225000000Z00'00') /Creator "PDF::Class" /Producer "Raku PDF::Class 0.2.5" >> % PDF::COS::Dict+{PDF::Info} /Root: << /Type /Catalog /Pages 3 0 R >> % PDF::Catalog /Pages: << /Type /Pages /Count 1 /Kids ... /Resources ... >> % PDF::Pages /Kids: [ 4 0 R ] % PDF::COS::Array[PDF::Content::PageNode] [0]: << /Type /Page /Contents 5 0 R /MediaBox ... /Parent 3 0 R >> % PDF::Page /Contents: << /Length 1944 >> % PDF::COS::Stream /MediaBox: [ 0 0 595 842 ] % PDF::COS::Array[Numeric] /Resources: << /ExtGState ... /Font ... /ProcSet ... /XObject ... >> % PDF::COS::Dict+{PDF::Resources} /ExtGState: << /GS1 6 0 R >> % PDF::COS::Dict[Hash] /GS1: << /Type /ExtGState /ca 0.5 >> % PDF::COS::Dict+{PDF::ExtGState} /Font: << /F1 7 0 R /F2 8 0 R /F3 9 0 R >> % PDF::COS::Dict[PDF::Resources::Font] /F1: << /Type /Font /Subtype /Type1 /BaseFont /Helvetica-Bold /Encoding /WinAnsiEncoding >> % PDF::Font::Type1 /F2: << /Type /Font /Subtype /Type1 /BaseFont /Helvetica /Encoding /WinAnsiEncoding >> % PDF::Font::Type1 /F3: << /Type /Font /Subtype /Type1 /BaseFont /ZapfDingbats >> % PDF::Font::Type1 /ProcSet: [ /PDF /Text ] % PDF::COS::Array[PDF::COS::Name] /XObject: << /Im1 10 0 R /Im2 11 0 R >> % PDF::COS::Dict[PDF::Resources::XObject] /Im1: << /Type /XObject /Subtype /Image /BitsPerComponent 8 /ColorSpace /DeviceRGB /Filter /DCTDecode /Height 254 /Width 200 /Length 8247 >> % PDF::XObject::Image /Im2: << /Type /XObject /Subtype /Image /BitsPerComponent 8 /ColorSpace ... /Height 42 /Width 37 /Length 1554 >> % PDF::XObject::Image /ColorSpace: [ /Indexed /DeviceRGB 255 12 0 R ] % PDF::ColorSpace::Indexed [3]: << /Length 768 >> % PDF::COS::Stream 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.

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. ## See also - [PDF::Lite](https://github.com/p6-pdf/PDF-Lite-p6) - A Lite-weight alternative -
