It's not an official API and should be safe to remove - there may be more as consequence of these...as always ;-) Of course some UnitTests would be nice, too, best with EMF+ test data files which make use of the new stuff. As Thorsten already stated: Help much appreciated! Regards, Armin (alg) How hard would it be to move the workbench example in VCL to use this? https://cgit.freedesktop.org/libreoffice/core/tree/vcl/workben/mtfdemo.cxx
Not too hard - indirectly it will partially use it already, it will read the metafile (|ReadWindowMetafile), but still paint it as metafile using vcl (||maMtf.Play). |||Instead you may use a Graphic (which you construct using the Metafile)/GraphicObject (which you construct using the Graphic), and something like in paintGraphicUsingPrimitivesHelper/paintUsingPrimitivesHelper like in sw, but only the parts that construct the drawinglayer::primitive2d::GraphicPrimitive2D. You may also directly use a drawinglayer::primitive2d::MetafilePrimitive2D, then you only need the transformation and the Metafile, and a drawinglayer::processor2d::BaseProcessor2D (best is to use drawinglayer::processor2d::createProcessor2DFromOutputDevice, that will do all stuff for you).
