I don't know if that's a problem with TikZ or ConTeXt (no time to
debug now, but maybe I can try to prepare some minimal example that
fails; later). ConTeXt MKII works fine on the same document.
this has to do with the fact that tikz manipulates documents resources
it probably went unnnoticed in previous mkiv and mkii, but that way tikz was
obscuring regular context resource handling (i.e. when you use mp an tikz
mixed one of them wins with respect to resources so the other kind's graphics
fail to view i.e. shades, transparencies, etc)
therefore in mkiv all access is shielded and goes via special macros:
\pdfbackendsetextgstate {name}{legal pdf}
\pdfbackendsetcolorspace{name}{legal pdf}
\pdfbackendsetpattern {name}{legal pdf}
\pdfbackendsetshade {name}{legal pdf}
normal "legal pdf" is a reference like 123 0 R
If more access is needed, i can add it but it will always go via an interface
as in mkiv most \pdfcommands are going away.
So, tikz needs to be adapted to this. A few weeks ago I looked at it but
found out that i had an old version so delayed it.
I am using the latest context minimals with latest tikz.
Test file:
\logginall
\usemodule[tikz]
\starttext
\input knuth
\stoptext
The log file says
\pgfu...@addpdfresource@colorspaces #1->\appendtoPDFdocumentcolorspaces
{#1}
#1<- /pgfprgb [/Pattern /DeviceRGB]
{undefined}
So, \appendtoPDFdocumentcolorspaces is undefined.
Now, \append...colorspaces is defined in back-pdf.tex which AFAIU that
file is not loaded. It is redefined in spec-fdf.mkii, so mkii uses that
defininition. In mkiv, back-pdf.mkiv defines \pdfbackendsetcolorspace.
So, which command should tikz use so that it works with both mkii and
mkiv. Or should it do a \beginLUATEX redefinition of some macros for mkiv?
The relavant tikz file is tex/generic/pgf/pgfutil-context.def so the
changes there will not affect latex.
