So in short, I ask if there is a better way please. The images below are enlarged so you can better see aliasing, blurring etc.
1] Firstly, I have echoed some unicode chars in urxvt terminal with dejavu 18pt ttf font. Nice and sharp, as desired.
Code: Select all
echo -ne "aaa \u259A bbb \u256c ccc \u2591 ddd"

2] Next, I created an image of a unicode message using dejavu 14pt ttf font. Some blurring though.
Code: Select all
msg=$(echo -ne "aaa \u259A bbb \u256c ccc \u2591 ddd")
convert -font DejaVu-Sans-Mono-Bold -pointsize 14 label:"$msg" out.png

3] Now, I created the same unicode text, but with anti-aliasing disabled. Sharp, but still looking odd.
Code: Select all
msg=$(echo -ne "aaa \u259A bbb \u256c ccc \u2591 ddd")
convert -font DejaVu-Sans-Mono-Bold -pointsize 14 +antialias label:"$msg" out.png

4] Lastly, I create text image with IM using the fixed bitmap font. But the unicode chars failed to render at all.
Code: Select all
msg=$(echo -ne "aaa \u259A bbb \u256c ccc \u2591 ddd")
bitmapfont='-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso8859-1'
convert -font $bitmapfont label:"$msg" out.png

In short, none of the methods I've used above have given me nice sharp unicode cahrs in an image. So I ask, is there a better way.
Code: Select all
