How to get the font pixel height using PIL's ImageFont class?

 

Font Loading 후, font와 관련된 요소 추출 시, 참고

 

+) PIL이 update 되면서 text 자체의 box를 Fit하게 가져오는 코드가 생김

text_bbox = draw.textbbox((0, 0), text, font=font)
draw.rectangle(text_bbox, outline=(0, 150, 150), width=2)#CYAN color

+) 특수문자는 예외..

 

def font_inner_bbox():

    im = Image.new('RGB', (700, 400), (200, 200, 200))
    text = 'AQj'
    font = ImageFont.truetype('./resources/font/handwriting_font/FONT.ttf', size=220)
    ascent, descent = font.getmetrics()
    print(ascent, descent)
    # font
    # ascent (the distance from the baseline to the highest outline point)
    # descent (the distance from the baseline to the lowest outline point, a negative value)
    (width, height), (offset_x, offset_y) = font.font.getsize(text)
    draw = ImageDraw.Draw(im)
    draw.rectangle([(0, 0), (width, offset_y)], fill=(237, 127, 130))  # Red
    draw.rectangle([(0, offset_y), (width, ascent)], fill=(202, 229, 134))  # Green
    draw.rectangle([(0, ascent), (width, ascent + descent)], fill=(134, 190, 229))  # Blue
    draw.rectangle(font.getmask(text).getbbox(), outline=(0, 0, 0))  # Black
    draw.rectangle([(0, offset_y), (width, ascent + descent)], outline=(0, 255, 255))  # SKY

    text_bbox = draw.textbbox((0, 0), text, font=font)
    draw.rectangle(text_bbox, outline=(0, 150, 150), width=2)#CYAN color
    
    draw.text((0, 0), text, font=font, fill=(0, 0, 0))
    im.save('result.jpg')

    print(width, height)
    print(offset_x, offset_y)
    print('Red height', offset_y)
    print('Green height', ascent - offset_y)
    print('Blue height', descent)
    print('Black', font.getmask(text).getbbox())
