Wkhtmltopdf
The version of wkhtmltopdf available in Debian/Ubuntu repositories does not support headers and footers (requires patched QT version), so it must be downloaded from the project's page.
-
0.12.0[.*]: not recommended, minimal supported version as of Odoo 8.- Several known issues fixed in 0.12.1.
-
0.12.1[.*]: recommended for Odoo 9.0 and earlier (.deb for Debian jessie, .deb for Ubuntu Trusty/Xenial, .deb (0.12.3.1) for Ubuntu Bionic (18.04)).
Known problems:- Some rare crashes during layout of multi-page tables (workaround: play with margins and/or dpi settings: 96, 100, 110dpi). Appears to be fixed in 0.12.2, but this version has worse problems.
- Known exponential memory usage and file descriptors usage when rendering documents with many pages (500+). Workaround: increase fd limit with
ulimit, remove header/footers (internal layout). Experimental horrible patch: split the long table in smaller chunks and usepyPdfto merge the pages. - Debian: no official release of 0.12.1 for Debian. We've built one for Jessie here
-
0.12.2[.*]: not recommended.
Known problems:-
--dpiparameter broken, causes ugly/broken layout (usingzoomcould be a partial workaround but requires complex ratio computations on win32 due to default dpi) - fails to execute external JS file in header/footer (Supposedly fixed in 0.12.3)
-
-
0.12.3: not recommended. Known problems:-
--dpiparameter still broken, see 0.12.2
-
-
0.12.4: not recommended. Was announced to include a fix for the--dpibug (see 0.12.2) which is better than thezoomworkaround, but apparently doesn't work on Linux. Some users report have tried to use option--disable-smart-shrinkingbut it still does not give the exact same result as 0.12.1.
Broken on mac OS (fix coming in 0.12.5). -
0.12.5-1: recommended for Odoo 10 to 15 or on older systems.-
--dpiparameter behaves differently than with 0.12.1. It is however possible to obtain the exact same rendering than with 0.12.1, at the same DPI level, by adding--zoom 96/DPI. For example for the default 90 DPI, add--zoom 1.0666.
This workaround is now enabled by default in Odoo 10 and later -
The
--disable-smart-shrinkingoption is not necessary and should not be used. -
Debian: official builds for older Debian ranging from Jessy and up to Buster (see discussion on issue #14127 for older builds).
-
The Odoo 11.0 Docker image is based on stretch and uses wkthmltopdf 0.12.5-1. Binary and libs are extracted in
/usr/local/{bin,lib}. -
Known problems:
-
opacityCSS directive seems broken< CCAA /a>, can be emulated with RGBA value
-
-
-
0.12.6.1-3: recommended for Odoo 16 and later and on newer systems.-
--disable-local-file-accessparameter is enabled by default. - Debian: official builds for Debian and Ubuntu versions starting at Debian 9 Stretch and Ubuntu 16.04 Xenial.
- The Odoo 16.0 Docker image is based on Ubuntu 22.04 "Jammy" and uses wkhtmltopdf 0.12.6-3.
