Re: [NTG-context] Offseting the baseline grid, and irregular columnsets

27 May 2022


      Thanks Rik, that fixed the issue with at which line the text begins, but I
still get the grid offset.

You left out the comma after the backspace setting. WIth that in, all is
well.

Thank you very much Aditya for looking into this. But I still have the
same baseline grid offset problem. Interestingly, when I remove the
columns, the text shifts downwards by two lines.
My code:
\definemeasure[xheight][0.1in]
\definemeasure[base][3\measured{xheight}]
% Since all distances are in terms of base units, specify the paper size
in those
% terms as well.
\definepapersize[slide][width=26\measured{base},height=20\measured{base}]
\setuppapersize[slide]
\setupinterlinespace[line=\measure{base}]
\setuplayout
[
topspace=2\measured{base},
header=\zeropoint,
headerdistance=\zeropoint,
height=middle, % Space for 20-4=16 lines
footerdistance=\zeropoint,
footer=\zeropoint,
bottomspace=2\measured{base},
%
cutspace=2\measured{base},
leftmargin=\zeropoint,
leftmargindistance=\zeropoint,
width=middle, % space for 26-4=22 col
rightmargindistance=\zeropoint,
rightmargin=\zeropoint,
backspace=2\measured{base}
grid=yes,
]

I'm attaching the pdf output.

Dear list,
My adventures into the world of grids continue. In the linked file
(slide_grid_overlay.pdf) there are two things I cannot yet achieve:
1. I want the baseline grid to evenly (vertically) divide the text
area, but my code produces a smaller height of the first line and an
additional space at the bottom.
You did not set footerdistance to zero. So, that takes up some space.
...
2. The number of columns is 21.5, that is the first column is 0.5
units
...
wide and the rest are 1 unit wide.
I believe that columns has to be an integer. Why do you want fractional
columns? Columns are useful because you can say:
\setlayer[name][line=2,column=3]{....}
for absolute positioning of layers. So, you can always use:
\setlayer[name][line=2,column=3,x=0.5\measured{base}]{....}
to move everything to the right by 0.5 units.
Another option is not to use columns at all, and simply do:
\setlayer[name][line=2,x=3.5\measured{base}]
which will place the layer at 3.5 units from the left edge of the text
area.
...
Here is what I got right now:
Currently your textwidth is not a multiple of base units. I have tweaked
the code below so that it is.
\definemeasure[xheight][0.1in]
\definemeasure[base][3\measured{xheight}]
% Since all distances are in terms of base units, specify the paper size
in those
% terms as well.
\definepapersize[slide][width=26\measured{base},height=20\measured{base}]
\setuppapersize[slide]
\setupinterlinespace[line=\measure{base}]
\setuplayout
    [
      topspace=2\measured{base},
      header=\zeropoint,
      headerdistance=\zeropoint,
      height=middle, % Space for 20-4=16 lines
      footerdistance=\zeropoint,
      footer=\zeropoint,
      bottomspace=2\measured{base},
      %
      cutspace=2\measured{base},
      leftmargin=\zeropoint,
      leftmargindistance=\zeropoint,
      width=middle, % space for 26-4=22 col
      rightmargindistance=\zeropoint,
      rightmargin=\zeropoint,
      backspace=2\measured{base},
