Re: [Rd] Question about grid.group compositing operators in cairo

2022-09-28 Thread Paul Murrell
Hi Would it work to explicitly record a filled-and-stroked shape as two separate elements (one only filled and one only stroked) ? Then it should only be as hard to apply the active operator on both of those elements as it is to apply the active operator to more than one shape (?) Paul On

Thank you for the very thorough explanation Paul. To answer your question on 11: The dsvg device, simply defines svg elements with their attributes (rect with fill & stroke in my examples). It does not do any internal image processing like cairo. My concern is how to proceed with the implemen

Thanks Brodie, this certainly seems like the same issue! I’ll add some comments to the issue tracker and hope that this can finally be fixed. Best, Taras > On 28 Sep 2022, at 12:33, Brodie Gaslam wrote: > > Hi Taras, > > I have not looked in detail at your examples here, but the > use

Hi Taras, I have not looked in detail at your examples here, but the use of evalq and sys.parent makes me think these issues: https://bugs.r-project.org/show_bug.cgi?id=17849 https://bugs.r-project.org/show_bug.cgi?id=15531 are possibly related. Best, B. On Wednesday, September 28, 2022 at

[Rd] parent.frame(n) produces different result from sys.frame(sys.parent(n))

2022-09-28 Thread Taras Zakharko
