I'm using xelatex (cf. my minimal code example)

I would like to know how to convert my image in bitmap rather than having a lot of gradation? Is it possible to do so with xelatex?

I would like to convert the image like something close to the second part part of the image (like some uniform pixels) :

    The image you show should almost certainly not be in png (or any bitmap) format. It should be prepared in a scalable format (e.g., eps, pdf, svg) so that it can be zoomed in without loss of quality (like the first A in your last image). If, for any reason, it must be in a bitmap format like png, one usually asks the program that creates the image to use or (not use) anti-aliasing on the fonts. Your close-up of "du gra" shows characters that have had antialiasing applied. This looks smoother at low magnification. The second A in your last image has not had antialiasing applied.

  • The problem is, you're providing xelatex w/ an anti-aliased pixel image --- if you convert it to a posterized file w/ few enough colours in it you'll have a very jagged image. The best thing to do is to re-create the chart using some tool which will make a press-ready, vector .pdf Commented Dec 4, 2013 at 19:53

Your close-up of "du gra" shows characters that have had antialiasing applied (border pixels are grayed). This looks smoother at low magnification. The second A in your last image has not had antialiasing applied.
