Hello Marco,
what for do you need the jpg-files.
I made a solution to preview pdf files for a docViewer. There I open the pdf and make a screen shot.
If you are interested please let me know.
Best regards,
Otto

Not available for Linux and OSX, only for Windows

We need to keep searching...

FWH has already implemented coversion of jpeg to pdf natively without the need of any external library. But the code is static inside \fwh\source\prv2pdf.prg.

You can remove the static declaration of FWPDF class in the above program and use it in your applications.

example

Code: Select all  Expand view

oPdf := FWPDF():New( cNewPdfFile )
oJpgBuf := MemoRead( <jpegfile> )
oPdf:nPage := 1
oPdf:WritePage( oJpgBuf )
oPdf:Close()
 

Haven't yet applied my mind to do the opposite.

Hello,

I tested latest preview posted by Master Antonio at FiveDbu, and the pdfs generated by native FWH are too big in size (one page, almost 4 mb).

I don´t have Office 2007.

Also, if I try to generate a pdf > 100 pages, it produces an hb_out.log at Harbour.

Elvira,

Please post the hb_out.log contents here, thanks

There was a memory leak bug in DibToStr(), thanks to Rao that saw it

Fixed and testing, we will publish a new build in a day or two. This was only appearing on a large print preview.

This is the fix in source/winapi/dib.c:

Code: Select all  Expand view

HB_FUNC( DIBTOSTR )  // ( hDib ) --> lSuccess
{
   long lSize;
   char * pDib;

   #ifndef _WIN64
      pDib = DibToStr( ( HGLOBAL ) hb_parnl( 1 ), &lSize );
   #else  
      pDib = DibToStr( ( HGLOBAL ) hb_parnll( 1 ), &lSize );
   #endif

   hb_retclen( pDib, lSize );
   hb_xfree( ( void * ) pDib );  // Here !!!
}

Antonio,

Are not others ways to create FWH PDFs without Office, and without this enormous capacity needed for one page, 4 mb ?

I use a virtual printer named PDFill Pdf Writer, who produce my pdf manuals, with for example 707 pages for only 9307 ko.
Inside there is a lot of png images of my soft. This product work perfect, i use it since a long time.

If you want to see, the manual is here : http://www.icim.fr/pdf/icim_facturation ... erence.pdf

I think it would be good if the users of my softs could print directly on pdf without virtual printer.
It is the only reason who do me change and let down PDFill Pdf Writer, because it is the better product
than i know to make PDFs with no limited numbers of pages, in a extraordinary little file size.

Badara,

you have 3 possibilities to create a pdf file.

1: using word (if installed)
2: using an printer driver that creates pdf.
3: you can use HaruPdf lib that comes with (x)harbour. With this lib you can create pdf directly from your app. There is good sample in the contrib folder of (x)harbour.
