ConTeXt-defined colours broken in TikZ in MkIV with latest betas

ConTeXt-defined colours broken in TikZ in MkIV with latest betas

[Mojca Miklavec]

Hi,

The following example works in MkII and it works in TeX Live 2014, but
it fails with the latest beta (it draws a black rectangle instead of
using the defined colour):

\usemodule[tikz]
\starttext
\definecolor[mycol][r=0.9,g=0.8,b=0.8]
\starttikzpicture
\fill[mycol] (0, 0) rectangle (2,4);
\stoptikzpicture
\stoptext

It would be really nice to fix this in time for TeX Live 2015.

Thank you,
    Mojca

Hi

I can confirm this bug. It worked fine for me a week before. It seems to be
a bug in one of the latest beta.

Thanks for fixing it
Christian

Hm, i'm a bit puzzled why some suggested patched are nto in the 
distribution. Anyway, attached a more modern variant

you need a beta that i just uploaded because i found out that when tijz 
predefines some mixed colors it assumes rgb color space

your example then runs ok here

Re: ConTeXt-defined colours broken in TikZ in MkIV with latest betas

[-- Attachment #1.1: Type: text/plain, Size: 2485 bytes --]

Thanks Hans for the fix!

I have noticed, that spotcolors can be used in tikz, but they are darker.
Is that wanted or a bug?

MWE:

\usemodule[tikz]
\starttext
\definecolor[gruen][c=0.52,y=0.86]
\definespotcolor[mycol][gruen][p=1]
\definespotcolor[mycol_h][gruen][p=0.5]
\definespotcolor[mycol_q][gruen][p=0.25]
\startcolor[mycol]
{\bfa Test Test Test Test Test}
\stopcolor

\starttikzpicture
\fill[mycol] (0, 0) rectangle (2,4);
\fill[mycol_h] (2, 0) rectangle ++(2,4);
\fill[mycol_q] (4, 0) rectangle ++(2,4);
\stoptikzpicture
\stoptext


I expect the first rectangle to have the same color as the (wanted) color
of the text. But the color of the text is closer to the color of the
rectangle in the middle (50%).

they will map onto cmyk or rgb depending on definitions ... don't expect 
advanced context color models to work with tikz (but they do work with 
metafun)

[-- Attachment #1.1: Type: text/plain, Size: 2312 bytes --]

Thanks Hans for clarification. But even with simple context color models
(that worked before) I get other colors.

MWE:

\usemodule[tikz]
\setupbodyfont[40pt]
\starttext
\definecolor[mycol][c=0.23,m=0.58,y=0.88,k=0.45]
\definecolor[mycol_h][c=0.115,m=0.29,y=0.44,k=0.225]
\definecolor[mycol_q][c=0.055,m=0.145,y=0.22,k=0.1125]
\startcolor[mycol]
{\bfa •••••••• Test}
\stopcolor

\starttikzpicture
\fill[mycol] (0, 0) rectangle (2,4);
\fill[mycol_h] (2, 0) rectangle ++(2,4);
\fill[mycol_q] (4, 0) rectangle ++(2,4);
\stoptikzpicture
\stoptext

I'm not so familiar with metafun, so I couldn't do the rectangle with
metafun (the different colors between context/metafun and tikz would
certainly be better visible so). But the bullet shows, that the text color
isn't the same as the tikz-figure. But they should as they are identical.
Something must have changed in color handling.

Re: ConTeXt-defined colours broken in TikZ in MkIV with latest betas

[Christian Prim]

[-- Attachment #1.1: Type: text/plain, Size: 2743 bytes --]

Hi Hans

is it correct, that with the new beta one can just use rgb-colors using
tikz or is there a bug preventing the usage of cmyk-colors as it used to
work before?

Thanks!

Christian

PS.: See mail below for MWE showing false cmyk colors in tikz.

cmyk should work ok but afaik tikz assumes rgb in some cases so that 
prohibits that we can do automatic conversion tp other color spaces at 
he context end

Re: ConTeXt-defined colours broken in TikZ in MkIV with latest betas

[Christian Prim]

[-- Attachment #1.1: Type: text/plain, Size: 6757 bytes --]

Hi Hans

sorry to ask again. But the different color handling between
context-version before 2015.04.14 00:54 and
context-version 2015.04.14 00:54 is remarkable and annoying.

See attached pdf-documents. Both have exactly the same source:

\usemodule[tikz]
\setupbodyfont[40pt]
\starttext
\definecolor[mycola][c=0.23,m=0.58,y=0.88,k=0.45]
\definecolor[mycolb][c=0.115,m=0.29,y=0.44,k=0.225]
\definecolor[mycolc][c=0.055,m=0.145,y=0.22,k=0.1125]

\starttikzpicture
\node[fill=mycola,rectangle, minimum height=4cm,minimum 
width=2cm,anchor=south west] {\startcolor[mycola]T\stopcolor};
\node[fill=mycolb,rectangle, minimum height=4cm,minimum 
width=2cm,anchor=south west] at (2,0) {\startcolor[mycolb]T\stopcolor};
\node[fill=mycolc,rectangle, minimum height=4cm,minimum 
width=2cm,anchor=south west] at (4,0) {\startcolor[mycolc]T\stopcolor};
\stoptikzpicture
\stoptext

I write in each box the letter T with exactly the same color as the 
underlying box. Textcolor is set using context, fill color of the box 
is set using tikz.

old.pdf shows the correct color handling. The letter T has exactly the 
same color as the box and therefore disappears.

With newest beta (new.pdf) the letter T is visible.

Must I now stay with an old beta or can this "bug" be fixed? Perhaps 
it's a bug in tikz...

Thanks
Christian

i found out that it relates to the lack of gray support (which in fact 
seems to be rgb support)

so the next beta might work ok for you (no upload yet)

Re: ConTeXt-defined colours broken in TikZ in MkIV with latest betas

[Christian Prim]

[-- Attachment #1.1: Type: text/plain, Size: 4219 bytes --]

Hi Hans

I don't know if the latest beta already has the new code. But I can
confirm, that there is still a difference between tikz-colors and
context/metafun colors.

TikZ translates c=1,m=1 in (native) RGB, that is b=1, which is in some way
correct.
ConTeXt translates c=1,m=1 in something I couldn't really define (perhaps
sRGB or some other color profile) r=0.183... g=0.191... b=0.574... or in
Web-Hex: #2e3092

or back to cmyk: c=.68, m=.67,k=.43 (which is blue with some key-value
compared to TikZ with k=0)

So I think that TikZ and ConTeXt don't use the same color profile....

Hope it could help somewhat to solve my problem.

Thanks
Christian

your example works ok here (with the tikz def file i made last week)

i also made

\setupcolors[cmyk=no]
\setupcolors[rgb=no]
\setupcolors[cmyk=no,rgb=no]
\setupcolors[state=stop]

working (nothing needed in tikz as the code that interfaces to it does 
that) which will be in the next beta

for the fix!
