Drawing ascii 0xA

[ZX-80]

I have some code that takes a few fonts from INT10h.org and outputs them as 64x4 character images

from PIL import Image, ImageDraw, ImageFont

FONT_NAME = "Px437_EverexME_7x8.ttf"
FONT_SIZE = 8
ROWS = 4
COLUMNS = 256 // ROWS

font = ImageFont.truetype(FONT_NAME, FONT_SIZE, encoding='utf-8')
def draw_bitmap() -> Image:
    for row in range(ROWS):
        text = ''.join(chr(i + COLUMNS * row) for i in range(COLUMNS))
        if row == 0:
            _, _, width_image, height_row = font.getbbox(text)
            image = Image.new("RGB", (width_image, height_row * ROWS), "black")
            draw = ImageDraw.Draw(image)
        draw.text((0, height_row * row), text, "white", font, allow_multiline=False)
    return image

draw_bitmap().save(f"{FONT_NAME}.png")

But because ascii 10 is being interpreted as a newline, I get this:

The docs for the text argument in ImageDraw.text() state:

If it contains any newline characters, the text is passed on to multiline_text()

How do I bypass this and force it to ignore the newline? I feel like I'm missing something really simple. For now, I've resorted to modifying ImageDraw.py and adding an allow_multiline argument that skips the self._multiline_check(text) when false, but that's obviously far from ideal:

There is currently no way to do this with ImageDraw, and I'm not sure how much interest there would be in adding support for it.

I'd suggest you just copy the relevant code from ImageDraw.text:

        def text_force_singleline(draw, xy, text, font, fill, **kwargs):
            class FakeBitmap:
                def load():
                    pass
            bitmap = FakeBitmap()
            mask, offset = font.getmask2(text, "L", **kwargs)
            bitmap.im = mask
            coord = xy[0] + offset[0], xy[1] + offset[1]
            draw.bitmap(coord, bitmap, fill)

(Note that your use of font.getbbox does not actually give you the size, but that is probably fine with your font. For your specific use-case you might be interested in using width, height = mask.width, mask.height and coord = (0, height * row), i.e. ignoring the offset, but this might not be helpful for other fonts.)

I think it's much easier to omit 0xA from the string.
