Thank you Martin,
Following the link I compiled correctly. Therion and Lock are working.
But I can’t find xtherion..
What I have missed?

Re: [Therion] Plan gridline colour changes unpredictably

[Bruce Mutton]

Thanks Martin

Highlights the dangers of absorbing a language by osmosis.  A false sense of 
understanding!

I’ll try that out and see how it works.

 

Out of interest I went back over old maps to check the colour of my gridlines.  
Until a few weeks ago I only ever used the default rgb colour model, and even 
now I only specify rgb, but occasionally force Therion to convert by specifying 
a cmyk colour model.  I found that I actually got a random section of the two 
gridline output colours over previous years.  My excuse for not picking it as a 
Therion behaviour is that I routinely use a number of pdf viewers and printers. 
 They all present line thicknesses and colours slightly differently. Especially 
Sumatra pdf compared to most others.

Hi,

 

0.5white doesn't work in CMYK properly (it's equivalent to 0.5*(0,0,0,0) = 
(0,0,0,0) = white)

0.1black doesn't work in RGB (it's 0.1*(0,0,0) = (0,0,0) = black)

 

So your formula produces 50% gray in RGB and 10% gray in CMYK. No idea why you 
got 10% gray in some RGB setups, some test data would be needed.

 

To get 10% grey colour you need to use 0.1[white,black] which works in all RGB, 
CMYK and Grayscale.

 

Cheers

Martin

I have in my layout some metapost code to redefine the plan gridlines, used 
without apparent problem for perhaps 10 years.  It includes a colour 
specification…

 

withcolor 0.1black+0.5white;

 

Mostly they come out like this, very light grey.  This example is exported 
using colour-model cmyk, but most of the time using colour-model rgb it looks 
exactly the same, in my current project (only variables are colour map-fg, some 
map previews on or off and the colour model).



 

For some reason, in my current project, if I use colour-model rgb for a 
particular output variant, I get a much darker gridline, as below.  Other 
variants with rgb, the colour of the gridline matches the first example.



 

Any hints as to why the difference?

I might have expected this to occur with the new cmyk colour model, but it does 
not.

So far it has only happened with in a single specific case when using the rgb 
colour model.  I’ll watch for more cases…

Printers are allway dependent on setup of colour management in its driver. Pro 
printers are dependent on setup of RIPs sending data to them. Not easy task.
