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}, % columns=22, columndistance=1pt, % grid=yes, ] \showframe \showgrid \starttext \input tufte \stoptext Aditya
