http://www.international-presence.com/images/nodes/dataformatter.png

To create a PDF document create a new custom data formatter in your task. Be sure to select 'PDF Document' as the 'Type of document to produce'.

This will then create the template for your PDF instructions.

http://www.international-presence.com/images/docs/pdf/dataformatterscreen.png

As usual if you enter < then the helper will appear with a list of options and permitted tags for the PDF.

Note it is actually the saving option that tells presence to send these instructions through the PDF formatter to generate the file.

To create a PDF file you need to set the 'Write Output' option to 'Into PDF File'

If you were to select 'To File' then the instructions themselves will be saved as pure text. This is useful if you need to send the instructions to us for debugging purposes, as we can then put the file into a task and run it through the PDF formatter to see what is happening.

http://www.international-presence.com/images/docs/pdf/dataformattersave.png

To create a PDF file we create a series of instructions similar to html. The language is a well structured html with some extra tags that are specific to the PDF. Each tag should be terminated with an associated closing tag. eg a <page> should eventually include a </page>

At present only basic formatting is supported, so no style sheets or inline formatting is allowed.

Acceptable tags

<pdf>

Denotes the start of the PDF

<document>

Describes the document properties and can have the following optional attributes

userpassword - if added then this is needed to open the pdf file

ownerpassword - if added then this is needed to edit the pdf file

allowprinting - whether the document can be printed (true/false)

allowcopy - whether the document can be copied (true/false)

pagenumbers - whether the document will include automatic page numbers (true/false)

landscape - landscape mode (true/false)

header - image that can appear on every page, aligned at the origin(0,0) eg ".\res\images\ipheader.png"

footer - image that can appear on every page, aligned at the bottom eg ".\res\images\ipfooter.png"

pagesize - eg a1 a2 a3 a4 ledger legal letter note 22,33

marginleft - space for left margin

marginright - space for right margin

margintop - space for top margin

marginbottom - space for bottom margin

<page>

Denotes a new page, so that at any point in the document we can start a new page. This has similar attributes to the document, but whereas the document attributes cover every page, these can be specific to this page only.

landscape - landscape mode (true/false)

header - image that can appear on every page, aligned at the origin(0,0) eg ".\res\images\ipheader.png"

footer - image that can appear on every page, aligned at the bottom eg ".\res\images\ipfooter.png"

pagesize - eg a1 a2 a3 a4 ledger legal letter note 22,33

marginleft - space for left margin

marginright - space for right margin

margintop - space for top margin

marginbottom - space for bottom margin

thispageonly - dictates whether these are attributes are to be used for subsequent pages or not.

<p>

As in html this describes a new paragraph

<table>

Similar to html, allows you to create a new table and can have the following attributes

width % The width of the table (as a percentage of the page width)

cellpadding - The spacing between the text and the cell

cellspacing - The spacing between cells in the table

border - Lined border thickness

positionabs - Set if you want to position the table in a specific fixed position

align - left|center|right|justify

bgcolor - The background color of the cell/table

title - The associated title

caption - The associated caption

As in html to define a new row in the table use <tr> and to define a new cell <td> or <th> which is a header cell and so will be at the top of each page when the table carries over onto the next page.


Cell attributes

colspan - How many columns the cell spans

width % - How wide this cell is as a percentage of the table width

bgcolor - The background color for the cell

align - Alignment of text in the cell (left|center|right|justify)

valign - top|middle|bottom|baseline

nowrap - Set if you want the text in the cell to be on a single line

As in html tables are often used for setting out your content with no borders.

Table Example

Notice how the document is added into the

http://www.international-presence.com/images/docs/pdf/table1.png

Next we iterate over our unique ID for each row(in this case the task id)

http://www.international-presence.com/images/docs/pdf/table2.png

Finally we close the document

Here is the table created

<img>

src - url for image align - alignment on page (left|center|right|justify) scaleabs - scalefit - image tag watermark positionabs

<font>

type - Specify the font from one of 3 built in types, courier|helvetica|times

face - Specify the font type by giving a path to the file name eg, face="c:\\windows\\fonts\\Bell.ttf"

align - left|center|right|justify

valign - top|middle|bottom|baseline

color - Font color

size - Font size in points

positionabs - Absolute position of text between font tags

example <font face="c:\\windows\\fonts\\CURLZ___.TTF" align="right" size="14" color="red">Danger</font>

checkbox input

It is possible to include checkboxes in the document, these do not have to be within a <form> tag

 Example Of UnChecked Checkbox 

<input type="checkbox"></input>  would result in an unchecked check box

 Example Of Unchecked Checkbox

<input type="checkbox" checked="checked"></input>  would result in a checked check box

Miscellaneous

h1 h2 h3 h4 h5 h6 - Put this text in a header, eg <h1>Title</h1>

br - line break

hr - horizontal line

bold - Set bold on (also accepts b and strong)

u - underline

i - switch on italics

small - reduce text size

big - increase text size

Lists

ol - ordered list

Example

<ol>
<li>First</li> 
<li>Second</li> 
<li>Third</li> 
</ol>

ul - unordered list

Example

<ul>
<li>Unordered information. </li> 
<li>Ordered information. </li> 
<li>Definitions. </li> 
</ul>

Color

Colors can be defined as one of several labels or by hex as in html if you want more control.

For instance green could be specified as either '#00FF00','green'

Presence recognises the following labels as colors:-

black blue cyan darkgray gray green lightgray magenta orange pink red white yellow


Example Of Colors

<font color="#00FF00">I am green text</font>

<td color="blue">This cell will have a blue background</td>

Formatting Special Characters

Sometimes you may want to include special characters such as a < or a " As the document is expecting pure well formatted xml it won't let you do this so instead you must escape the characters, for instance putting &lt; will result in a <

&lt; <

&gt; >

&quot; "

&amp; &

\n space

\t space

&nbsp; space

It's also worth noting that several spaces or returns will get replaced with one space as in html. For behaviour other than that you can use preformatted text.

<pre>The  spaces   between    words    will   be  obeyed</pre> pre preformatted text, so between these tags all spaces and tabs will be obeyed, whereas normally several spaces or line breaks will be replaced with one space.

Absolute positioning

Sometimes you need to be specific when positioning text (for instance if the document is going to be scanned by an ocr reader, or if you wish to position an address so that it appears in the right position in a windowed envelope, or if you want to place text in the border).

Example Of Absolute positioning

 <font positionabs="575,822">Signed:_______________</font>

 <table positionabs="0,0" border="0">
  <tr>
   <td>Origin</td>
  </tr>
 </table>

In these instances it can be useful to use absolute positioning.

It's worth noting that an A4 page is 595 units across by 842 units down.

Also depending on the table width the table will be pushed left so that it is not hanging off the right hand side of the page. For instance, if the table width was 50% then the positionabs="500,200" would actually be positioned at 298,200.
