This question already has an answer here:

I wrote:

RasterizeWord[word_, font_, size_] := 
Rasterize[Style[word, FontFamily -> font, Black],RasterSize -> size,Background -> Gray] 
f=RasterizeWord["A", "Arial", 20]

and I got (after zoom):

enter image description here

with 18 pixels (easy to calculate). Why??

How to make it the grayscale?

I set antialising to none in Unity Tweak Tool (Linux) and I got:

enter image description here

So I tried:

RasterSize -> size, ImageSize -> size

I got the same result. But it is interesting that in GIMP:

enter image description here

when I Export["f.png", f]. I think something is wrong with the zoom.

  • $\begingroup$ You could disable subpixel antialiasing in your OS's text rendering settings. $\endgroup$ – Szabolcs Nov 6 '14 at 16:07
  • $\begingroup$ Replace RasterSize by ImageSize, you will get the correct width, see also recent mathematica.stackexchange.com/questions/64758/… $\endgroup$ – Alexey Bobrick Nov 6 '14 at 16:10
  • $\begingroup$ Thanks Alexey, but it is not true. $\endgroup$ – ZYX Nov 6 '14 at 16:59
  • $\begingroup$ @ZYX, on my system (MMA 10, Ubuntu 14), your code < Rasterize["A", RasterSize -> 20] // ImageDimensions > gives {9,18} . If you call instead < Rasterize["A", ImageSize -> 20] // ImageDimensions > , you get {20,34} on my configuration. Please, let me know, if you get a different result. $\endgroup$ – Alexey Bobrick Nov 6 '14 at 17:02
