Basic PDF manipulation using PDFKit

4d-plugin-pdf-kit

Perform basic PDF manipulation on OS X.

• PDF INSERT PAGES is rewritten to internally duplicate trailing pages before inserting new pages then finally remove the duplicate pages.

• PDF REMOVE PAGE is rewritten to internally exchange the target page before removing it.

New in 1.4

• Removed the "retain" patch for earlier El Capitan crash problem.
• PDF REMOVE PAGE is restored to use original code.

Note: Most page commands (insert, remove, exchange) will not work if a page is rotated. The plugin is not using PDF Kit to simply rotate a page, but rather, calling CGPDF to re-draw such pages on a rotated context. You should rotate the page at the very end.

New in 1.2

Passing 0 to PDF SET PAGE ROTATION will rotate all pages.

Fuite mémoire

Hi,
J’utilise votre plugin PDF Kit avec 4D 20R4 sur macOS 14 et je rencontre un problème de fuite mémoire.

Si vous appelez la commande, par exemple, PDF GET PAGE, dans le Process principal, la mémoire utilisée par 4D augmente, et ne redescend pas !

Voici une base exemple

PDF SET PAGE ROTATION2 not found

Hello,
I have installed the plugin on a 4D server (4Dv13) with the V11 version of the plugin to fix el capitan issue. The server is on OS X 10.9 and the other stations on El Capitan or 10.6.
The method PDF SET PAGE ROTATION is present and working but I can't find the method PDF SET PAGE ROTATION2.

V13 version?

Any chance of a V13 build?
