Solve:PDF Converter 3.02 in XP/2003 generates too large file

[lovison@algolsh.it]

Hi,
we have a strange behavior with all pc's of a customer (5 Windows XP / 2003 pc's) :
PDF Converter 3.02 generates a too large pdf file of ~ 5Mb
while the same source file with PDF Creator (http://www.pdfforge.org/)
is ONLY 200Kb. On my pc PDF Creator generates ~ 300Kb pdf file.

Any suggestion

Fabrizio

Customer's PC :
2 MS Windows SERVER 2003 (IE 7.0) with 3.5Gb RAM
4 MS Windows XP SP3 (IE 7.0) with 1Gb RAM

More info :

Customer's PDF file :

PDF Version : 1.3 (Acrobat 4.x) - 4.79 Mb - Pages 144 - Tagged PDF : NO - Fast WebView : NO

My's PDF file :

PDF Version : 1.4 (Acrobat 5.x) - 632.12 Kb - Pages 144 - Tagged PDF : NO - Fast WebView : NO

Why is'nt my PDF version the same? How do I change this PDF version ?

Hello,

If you and your customer don't have the same PDF version than you are either using different version of the PDF Converter or different settings while generating the PDF file.

Are you and your customer using the same version and the same settings for the PDF Converter?

Please note that to get optimal PDF file size for PDFs containing images, you need to use Compression algorithms available in the PDF Converter. I suggest that you try Jpeg Compression or Automatic Compression

Hi Joan and thank you for the reply

My customer and I have the same PDF Converter, 3.02, and the same version program to generate pdf.

Today I added in our program the flags : JPegLevelLow + AutoCompression
with this result when I print a file with 200 pages :

- On my PC : before 612Kb -> after 612Kb (exactly the same)
- On customer's PC : before ~ 13Mb -> after ~ 4Mb

But the PDF type is always PDF 1.3 (Acrobat 4.x)
How I can still improve? Why this difference between me and the customer?

Have a nice day!

Hello,

If the PDF files have different version numbers than there is definitely a difference in the printer settings in the PDF Converter between you and your customer.

At your location, have you tried installing your application on a clean PC?

One other thing that my help you in reducing the file size is downsample images to fit output resolution and Remove Duplicate Images.

I have included below a code snippet on how to enable this option.


HANDLE hPrinter;
hPrinter = PDFDriverInit( "My Application Converter" ); // create a new printer
If ( hPrinter )
{
SetVerticalMargin( hPrinter, 0 ); // set minimum vertical margin to 0
SetHorizontalMargin( hPrinter, 0 ); // set minimum horizontal margin to 0
SetImageOptions( hPrinter, 3 ); // downsample images to fit output resolution + Remove Duplicate Images
SetDefaultConfig( hPrinter ); // make the values default
}


thanks
Jose

Perfect!
With SetImageOptions( hPrinter, 3 ) the size of customer's pdf is acceptable!

Thank you very much!

Best regards.
