# Form8sn

Generate PDF based templates, and fill them in from data objects

The general plan:

-----------------

1. Someone with a form does a Print to PDF with all the spaces blank

2. They get a data structure (schema) from another app or API

3. Both the PDF and the data are loaded into the **Form8sn UI**, and they:

   - Place boxes on the PDF page surfaces

   - Add rules to partition the data and repeat PDF pages (plus running totals and the like)

4. This is exported to a command file embedded in a modified version of the PDF

5. A programmer can then pass the command file and data to the **Form8sn SDK** to get back a finished PDF

The PDF generation phase should be as fast as possible. If we can, it should be a streaming process so we

don't need to load the whole PDF template or output into memory.

Components

==========

* **PDFSharp** - A modified version of the main project (so I can add or specialise bits)

* **PortableGdi** - A minimal version of `System.Drawing` to support PDFSharp. Based on GNU Portable.Net base libraries.

* **BasicImageFormFiller** - GUI app to take scanned paper forms (in JPEG) and

  fill them in from arbitrary data, based on examples.

* **TestApp** - Console app scratch space

* **PdfSharp.Charting** - Currently unused.

* **Form8snCore** - File formats and filtering to produce PDFs from project files

* **WebFormFiller** - .Net MVC website and JS app for editing Form8sn projects

To-do:

------

* [ ] Write some documentation

* [x] Ensure the core PDFsharp and Form8snCore don't use GDI+ **(important)**

  * [x] Portable system.drawing

  * [x] JPEG reading and writing ( `Portable.Drawing.Imaging.ImageFormats.JpegReader.Load` )

  * [x] Font reading & metrics ( `PdfSharp.Drawing.XFontSource.GetOrCreateFromFile` )

  * [x] Remove defunct platform specific calls in PDFsharp.

* [x] Handle PDFs as input

* [x] Decode PDF forms so we can use existing 'boxes'

* [ ] Embed Form8sn instructions in PDF files and handle those? *(not important)*

* [x] Web-based form editor?

* [ ] Full suite of tests
