SynPDF now generates (much) smaller PDF file size

We have reduced PDF generated file size for all version of the PDF format, by trimming any uneeded space in the generated content.

We introduced a new optional PDFGeneratePDF15File property for even better compression, using advanced features (Object Streams and Cross-Reference Streams) of the PDF 1.5 format.
This PDF 1.5 format needs Acrobot 6.0 and up to open them.
Which should be the case on your computer.

Can be up to 70% smaller for a pdf with a lot of pages with simple textual context.

I suspect our library is able to generate the smallest file size possible, even in regard to other alternative libraries.
Open Source can be great, can't it?

SynPDF now implements 40 bit and 128 bit security

The trunk version of our Open Source SynPdf library now features encryption using 40 bit or 128 bit key size.

This is a long awaiting feature, and sounds working just fine from my tests.
Speed has been optimized (as usual with our libraries), as a consequence encrypting the content will only be slightly slower.

Synopse PDF Engine 1.18

Our SynPdf library was released as part of every mORMot version.
But the stand-alone .zip was still in 1.15 revision.

I have updated it, and now it reflects the latest version from our source code repository (i.e. 1.18).
Open Source, working from Delphi 5 up to XE3.

Thanks to nice proposals - like those from Sinasa - conversion engine from metafile content is pretty complete.
Font fallback has been introduced for glyphs not available in the current font, and some issues have been identified and fixed.
SynPdf unit can now link to standard ZLib.pas unit if you want to use it stand-alone and do not need our faster SynZip.pas + deflate.obj + trees.obj.

Forum and feedback are welcome on our forum.
Direct download link is available in our Download section.

But it's still working from all previous IDE versions, starting with Delphi 5, and still 100% free - released under GPL/LGPL/MPL license, choice is yours.

Synopse PDF Engine 1.14

Our SynPdf unit has been updated to the 1.14 version.

Some enhancements:

  • new SetCMYKFillColor and SetCMYKStrokeColor methods for TPdfCanvas
  • now handles EMR_POLYBEZIER* commands in conversion from meta file content
  • fixed EZeroDivided error when enumerating SetWindowExtEx(szlExtent(0,0))
  • some enhancements for better PDF/A-1 conformance to the standard: now includes the ICC profile for RGB pictures; corrected /Link flag and XML metadata; new header with 8 bit characters; correct outlines and other minor issues: now pass e.g. validation tests.

Compatible with Delphi 5 up to Delphi XE.

Source code released under GPL/LGPL/MPL license, on choice.
That means: free, like a bird, and like a beer.

Synopse PDF engine 1.7.2

The Unicode part of the Synopse PDF engine has been updated in order to support right-to-left languages and ligatures (i.e. glyph shaping).

Therefore, our Open Source engine is one of the few PDF producer able to natively handle Arabic languages. Even most commercial engines don't implement this nice feature.

Among its features, you can use a true TCanvas to create the PDF, and embed True Type fonts subsets. Of course, it's Unicode ready, and licensed under a MPL/GPL/LGPL tri-license.
