[Bioc-devel] Need help figuring out GeometryDoesNotContainImage-error on machv2-build for chimeraviz

[Hervé Pagès]

Hi Stian,

I went on machv2 and gave this a shot. I can reproduce the 
GeometryDoesNotContainImage error in an interactive session. I don't 
have an answer yet but I was curious about the "semi-transparency is not 
supported on this device" warning and was wondering if it could somehow 
be related with the error.

It turns out that the warning is actually easy to reproduce on a Mac 
with something like this:

   plot.new()
   lines(c(0.1, 0.22), c(0.5, 0.44), type = "l", lwd = 1, col = "#FF000080")

I think that the 4th byte (80) in the color specification ("#FF000080") 
is the level of transparency.

I can get this warning on machv2 **and** merida1. Some googling 
indicates that this is a pretty common warning on Mac. Since we don't 
get the vignette error on merida1 I think it's unlikely that the warning 
is related to the error.

I'll keep investigating the GeometryDoesNotContainImage error...

H.
