With MBS FileMaker Plugin 14.0 we include the DynaPDF Parser functions. These functions provides a top-level interface on the parser in DynaPDF. You can do various operation using them:

• Parse a page
• Find text on the page.
• Extract text on the page
• Delete text within a rectangle.
• Query coordinates for found text.
• Replace found text with new text.
• Set alternative font for new text.
• Finally write changes back to page.

The combination of these allows for a lot of things. Like finding text on a page and replacing it with new text for a little PDF editor. Or to find text and then:

• Draw rectangles around the found text to show it.
• Put highlight annotations on the text.
• Find website names or keywords and put WebLink annotations on them.
• Use DeleteText function to remove the text from the PDF.
• Find each character and then know the coordinates of every letter.

The possibilities from the handful of functions is enormous. Let's take a look on sample code:

# Find and Replace Text all pages in file Find and Replace Text

# Find Text all pages and replace with new text

# 

Set Variable [ $StartTime ; Value: Get(CurrentTimeUTCMilliseconds) ] 

# Initialize DynaPDF if needed

If [ MBS("DynaPDF.IsInitialized")  ≠  1 ] 

Perform Script [ Specified: From list ; “InitDynaPDF” ; Parameter:    ]

End If

# Clear current PDF document

Set Variable [ $pdf ; Value: MBS("DynaPDF.New") ] 

# Load PDF from container

Set Variable [ $r ; Value: MBS("DynaPDF.OpenPDFFromContainer"; $pdf; DynaPDF Replace Text::InputPDF) ] 

# import a page

Set Variable [ $r ; Value: MBS("DynaPDF.ImportPDFFile"; $pdf; 1) ] 

# 

# initialize parser

Set Variable [ $OptimizeFlags ; Value: 0 ] 

Set Variable [ $r ; Value: MBS( "DynaPDF.Parser.Create"; $pdf; $OptimizeFlags ) ] 

Set Variable [ $r ; Value: MBS( "DynaPDF.Parser.SetAltFont"; $pdf; "Helvetica"; 0; 12) ] 

# 

# 

# loop counting up from 1 to $count

Set Variable [ $count ; Value: MBS("DynaPDF.GetPageCount"; $pdf) ] 

Set Variable [ $index ; Value: 1 ] 

If [ $index ≤ $count ] 

Loop [ Flush: Always ]

# Now parse a page

Set Variable [ $r ; Value: MBS("DynaPDF.Parser.ParsePage"; $pdf; $index; "EnableTextSelection") ] 

If [ MBS("IsError") ] 

Show Custom Dialog [ "Failed to parse page" ; $r ] 

Else

# Run a find

Set Variable [ $continueFind ; Value: 0 ] 

Set Variable [ $r ; Value: MBS( "DynaPDF.Parser.FindText"; $pdf; DynaPDF Replace Text::SearchText; "CaseInsensitive"; $continueFind) ] 

If [ $r = 1 ] 

Loop [ Flush: Always ]

# Do the replace

Set Variable [ $r ; Value: MBS( "DynaPDF.Parser.ReplaceSelText"; $pdf; DynaPDF Replace Text::ReplaceText) ] 

# 

# Continue search

Set Variable [ $continueFind ; Value: 1 ] 

Set Variable [ $r ; Value: MBS( "DynaPDF.Parser.FindText"; $pdf; DynaPDF Replace Text::SearchText; "CaseInsensitive"; $continueFind) ] 

Exit Loop If [ $r ≠ 1 ] 

End Loop

# 

# Save changes back

Set Variable [ $r ; Value: MBS( "DynaPDF.Parser.WriteToPage"; $pdf; $OptimizeFlags) ] 

End If

End If

# 

# next

Set Variable [ $index ; Value: $index + 1 ] 

Exit Loop If [ $index > $count ] 

End Loop

End If

# 

# save

Set Field [ DynaPDF Replace Text::OutputPDF ; MBS( "DynaPDF.Save"; $pdf; "output.pdf" ) ] 

Set Variable [ $EndTime ; Value: Get(CurrentTimeUTCMilliseconds) ] 

Show Custom Dialog [ "Time" ; ($EndTime - $StartTime) ] 

# Cleanup

Set Variable [ $r ; Value: MBS("DynaPDF.Release"; $pdf) ] 

This does a search and replace while looping over all pages. Instead of doing the replace, we could of course query the coordinates on the page for later using the DynaPDF.Parser.SelectionBBox function. Then after we found all the positions, we can call EditPage to make changes and for example draw rectangles into the found places. Or add annotations.

Please try the new functions and let us know.
