Convert TrueType glyphs to PNG image?
Python3
Since nobody has really address the part that specifies for C++, Python, Ruby, or Perl, here is the Python3 way. I've tried to be descriptive, but you can simplify to work how you need it to.
Requirements: PIL (Pillow)
PIL's ImageDraw and ImageFont module
# pip install Pillow
from PIL import Image, ImageFont, ImageDraw
# use a truetype font (.ttf)
# font file from fonts.google.com (https://fonts.google.com/specimen/Courier+Prime?query=courier)
font_path = "fonts/Courier Prime/"
font_name = "CourierPrime-Regular.ttf"
out_path = font_path
font_size = 16 # px
font_color = "#000000" # HEX Black
# Create Font using PIL
font = ImageFont.truetype(font_path+font_name, font_size)
# Copy Desired Characters from Google Fonts Page and Paste into variable
desired_characters = "ABCČĆDĐEFGHIJKLMNOPQRSŠTUVWXYZŽabcčćdđefghijklmnopqrsštuvwxyzž1234567890‘?’“!”(%)[#]{@}/&\<-+÷×=>®©$€£¥¢:;,.*"
# Loop through the characters needed and save to desired location
for character in desired_characters:
# Get text size of character
width, height = font.getsize(character)
# Create PNG Image with that size
img = Image.new("RGBA", (width, height))
draw = ImageDraw.Draw(img)
# Draw the character
draw.text((-2, 0), str(character), font=font, fill=font_color)
# Save the character as png
try:
img.save(out_path + str(ord(character)) + ".png")
except:
print(f"[-] Couldn't Save:\t{character}")

tar xvzf ttf2png-0.3.tar.gz
cd ttf2png-0.3 && make
./ttf2png ttf2png -l 11 -s 18 -e -o test.png /path/to/your/font.ttf
eog test.png&
probably partly duplicate of How can I convert TTF glyphs to .png files on the Mac for free?
imagemagick can fulfill this kind of requests, should works fine on Mac/Linux/Windows. :-)
convert -background none -fill black -font font.ttf -pointsize 300 label:"Z" z.png
if a batch convert is needed, maybe you can consider use a little ruby script called ttf2png .
The PIL provides an API for this, but it's easy to use. Once you've got the PIL image, you can export it.
