使用PIL在其中绘制矩形和文本

使用PIL在其中绘制矩形和文本

你可以不用

composite()

from PIL import Image, ImageFont, ImageDraw, ImageEnhancesource_img = Image.open(file_name).convert("RGBA")draw = ImageDraw.Draw(source_img)draw.rectangle(((0, 00), (100, 100)), fill="black")draw.text((20, 70), "something123", font=ImageFont.truetype("font_path123"))source_img.save(out_file, "JPEG")

您可以创建带有按钮大小的空图像，并在其上放置文本，然后再将该图像放置在上

source_img

。这样，长文本将被剪切为按钮的大小。

from PIL import Image, ImageFont, ImageDraw, ImageEnhancesource_img = Image.open("source.jpg").convert("RGBA")# create image with size (100,100) and black backgroundbutton_img = Image.new('RGBA', (100,100), "black")# put text on imagebutton_draw = ImageDraw.Draw(button_img)button_draw.text((20, 70), "very loooooooooooooooooong text", font=ImageFont.truetype("arial"))# put button on source image in position (0, 0)source_img.paste(button_img, (0, 0))# save in new filesource_img.save("output.jpg", "JPEG")

编辑： 我

ImageFont.getsize(text)

用来获取文本大小并创建具有正确大小的按钮。

from PIL import Image, ImageFont, ImageDraw, ImageEnhancesource_img = Image.open("input.jpg").convert("RGBA")font = ImageFont.truetype("arial")text = "very loooooooooooooooooong text"# get text sizetext_size = font.getsize(text)# set button size + 10px marginsbutton_size = (text_size[0]+20, text_size[1]+20)# create image with correct size and black backgroundbutton_img = Image.new('RGBA', button_size, "black")# put text on button with 10px marginsbutton_draw = ImageDraw.Draw(button_img)button_draw.text((10, 10), text, font=font)# put button on source image in position (0, 0)source_img.paste(button_img, (0, 0))# save in new filesource_img.save("output.jpg", "JPEG")
