有没有办法用 Pillow 绘制带有渐变颜色的文本? [英] Is there a way, to draw Text with a gradient color with Pillow?

问题描述

我将要创建一个带有文字的图像.到目前为止，一切正常.现在，对于微调，我认为文本具有渐变颜色会很好.

I am about to create an image with text on it. So far everything is working fine. Now, for the fine-tuning, I thought it would be nice to have the text with a gradient color.

这是我目前的重点.

这就是我想要拥有的.

推荐答案

我设法生成了以下图像:

I've managed to generate following image:

使用该脚本:

from PIL import Image, ImageFont, ImageDraw

OUTPUT_IMAGE = '53952270.png'
BG_COLOR = (0, 102, 0)
TEXT = 'STIEFELSTANGE'
TEXT_COLOR = (255, 255, 255)
SHADOW_COLOR = (231, 255, 227)

image = Image.new('RGB', (212, 45), color=BG_COLOR)
draw = ImageDraw.Draw(image)
font = ImageFont.truetype('impact', 36)
text_size = font.getsize(TEXT)
draw.text((0, 0), TEXT, font=font)
pixels = image.load()
size = image.size

x_list = []
y_list = []
for x in range(size[0]):
    for y in range(size[1]):
        if pixels[x, y] == TEXT_COLOR:
            x_list.append(x)
            y_list.append(y)

shadow_height = text_size[1]/4
for x, y in zip(x_list, y_list):
    if y < min(y_list) + shadow_height or y > max(y_list)-shadow_height:
        pixels[x, y] = SHADOW_COLOR

image.save(OUTPUT_IMAGE)
