wPDF V3 embed data

jyarnott

The new features section says:

Binary Data embedding: You can store the document source which was used to create a PDF file within this PDF file. When you use WPTools for the PDF creation you can store the RTF source document inside of the created PDF data, the user only has to click on an icon to extract this document. This can be a great feature if you use it to embed programming examples within your programming manual!

We are very interested in looking at this for use in our software and are looking at upgrading but I can't find an api reference that documents this nor an example that shows it. I downloaded the examples. Can you point me toward this? Thanks.

Hi,

Embedding files requires this new API:

procedure EmbedData(const aName : string; r: TRect;
Icon : TWPEmElementIcon; data: TStream;
compressmode: TWPEmCompressMode; const FileExtension: string);

Code

Parameters:


const aName : string; 
This is the name which will be displayed as hint for this object. In the example above "Document.RTF". The name may be 99 chars long.


r: TRect;
This is the rectangle where to place the icon for the data. It is measured in canvas coordinates, this means you can use Canvas.StretchDraw( R, SomeImage ) and EmbedData with the same values for "R".


Icon : TWPEmElementIcon; 
The Icon to be displayed by AcrobatReader.


Possible values are: 
   wpemNone, 
   wpemPushPin,  
   wpemGraph, 
   wpemPaperClip, 
   wpemTag 


If you use wpemNone you can draw any image and place the hot spot at the same location.


data: TStream;


The data to be embedded.


compressmode: TWPEmCompressMode; 


The compression mode. If you embed already compressed data you should use wpemDontCompress, otherwise use wpemDefault.


const FileExtension: string


The file extension, for example RTF, ZIP or PNG.

It is executed during regular drawing and the coordinates uses the current "Canvas" coordinates.
