Usage

Import the import parts

from piltext import FontManager, ImageDrawer, TextGrid

Download fonts:

f = FontManager(default_font_size=20)
font1 = f.download_google_font("ofl", "roboto", "Roboto[wdth,wght].ttf")
font2 = f.download_google_font("ofl", "jersey10", "Jersey10-Regular.ttf")
f.default_font_name = font1
print(f.list_available_fonts())

Fonts with variations can be used

print(f.get_variation_names())

Create image with texts:

image = ImageDrawer(100, 100, f)
xy = (0, 0)
w, h, font_size = image.draw_text("Test", xy, font_variation="Bold")
xy = (xy[0], xy[1] + h)
w, h, font_size = image.draw_text("Test", xy)
xy = (xy[0] + w, xy[1])
w, h, font_size = image.draw_text("Test", xy)
xy = (xy[0], xy[1] + h)
w, h, font_size = image.draw_text("Test", xy, font_name=font2, fill=128)
xy = (0, xy[1] + h)
w, h, font_size = image.draw_text(
    "Test", xy, end=(100, 100), font_variation="Condensed Medium"
)
print(f"w: {w}, h:{h}, font_size: {font_size}")

image.finalize(inverted=False)
display(image.get_image())

Anchor can be used:

image = ImageDrawer(480, 280, f)
xy = (5, 3)
w, h, font_size = image.draw_text(
    "Long Text 1", xy, end=(480, (280 - 15) / 3), anchor="lt"
)
xy = (5, int(h * 0.85))
w, h, font_size = image.draw_text(
    "Long Text 2", xy, end=(480, xy[1] * 1.5), anchor="lt"
)
xy = (5, xy[1] + h)
w, h, font_size = image.draw_text(
    "Long Text 3", xy, font_size=font_size, font_variation="Thin", anchor="lt"
)
xy = (5, xy[1] + h)
w, h, font_size = image.draw_text("Long Text 3", xy, font_size=font_size, anchor="lt")
w, h, font_size = image.draw_text(
    "Long Text 4", (480 - 5, 280 - 5), end=(5, 5), anchor="rs"
)

image.finalize(inverted=False)
display(image.get_image())

TextGrid

image = ImageDrawer(480, 280, f)

grid = TextGrid(7, 4, image, margin_x=2, margin_y=2)
grid.print_grid()
merge_list = [
    ((0, 0), (0, 3)),
    ((1, 0), (2, 1)),
    ((1, 2), (2, 3)),
    ((3, 0), (6, 3)),
]
grid.merge_bulk(merge_list)
grid.print_grid()

can be used to improve text layout:

image.initialize()
grid.set_text(0, "Test1", font_name=font2)
grid.set_text(1, "Test2")
grid.set_text(2, "Test3")
grid.set_text(3, "Test4", anchor="lt")
image.finalize(inverted=False)
display(image.get_image())

The text can also be set as bulk using a list:

image.initialize()
text_list = [
    {"start": 0, "text": "Test1", "font_name": font2},
    {"start": 1, "text": "Test2"},
    {"start": 2, "text": "Test3"},
    {"start": 3, "text": "Test4", "anchor": "lt", "fill": 128},
]
grid.set_text_list(text_list)
image.finalize(inverted=False)
display(image.get_image())
