ph-pdf-layout

Java library for creating fluid page layouts with Apache PDFBox 3.x.

Please check the examples files to see what kind of PDFs may be created. Please see the unit tests on how to create and use the different elements.

System requirements:

At least Java 11 - newer versions should work as well
GitHub actions test with all LTS version (currently 11, 17 and 21)

The basic elements provided are:

PageLayoutPDF - the entry class, having a list of page sets
PLPageSet - a set of pages that share the same size and orientation and contain a set of elements. The assignments to pages happens dynamically.
PL elements - basic or complex layout elements ("PL" is short for "PDF Layout")
- Basic (inline) elements are
  - plain text in class PLText (Unicode of course)
    - For custom Open Source fonts to be used see the https://github.com/phax/ph-fonts project
    - Note: the available characters heavily depend on the used font. So if you get a "?" character, try loading a different font
  - and image in classes PLImage and PLStreamImage (whatever ImageIO can load).
- Basic (block) element is box (class PLBox)
- Layout elements are
  - horizontal box or h-box in class PLHBox - like a row of a table
  - vertical box or v-box in class PLVBox - like a column of a table
  - spacer-x in class PLSpacerX - a horizontal spacer - just in case you need explicit distance to a certain element
  - spacer-y in class PLSpacerY - a vertical spacer - just in case you need explicit distance to a certain element
  - page break in class PLPageBreak - an explicit page break that starts a new page
- The most complex element is a table, which consists of a number of "h-boxes" (rows) which itself consist of a number of "v-boxes" (columns) plus comes with repeating headlines etc.
  - See classes PLTable, PLTableRow and PLTableCell for details
- Elements can have the following properties - if you know CSS you should be familiar with it:
  - "min-size" - the minimum element size
  - "max-size" - the maximum element size
  - "margin" - a transparent outer border (outside of the border)
  - "border" - a visible border with different styles (between padding and margin)
  - "padding" - a transparent inner border (inside of the border)
  - "fill-color" - the background or fill color of an element

A set of example files as created from the unit test can be found in folder example-files. The source code for these examples is https://github.com/phax/ph-pdf-layout/tree/master/src/test/java/com/helger/pdflayout
