安装
使用 pip 安装:
pip install levicanvas
快速开始
from levicanvas import LeviCanvas
from PIL import Image
# 压缩图片
LeviCanvas.compress_image("input.jpg", "output.jpg", quality=80)
# 从URL加载图片
img = LeviCanvas.load_image_from_url("https://example.com/image.jpg")
# 创建圆角图片
rounded_img = LeviCanvas.get_round_image(img, radius=20)
# 生成二维码
qr_img = LeviCanvas.generate_qr_code("https://example.com")
# 绘制文本
font = ImageFont.truetype("arial.ttf", 24)
img = LeviCanvas.Draw_Text(img, font, (10, 10), (0, 0, 0), "Hello World")
主要功能
图片处理
压缩图片
# 压缩图片到指定质量
success = LeviCanvas.compress_image("input.jpg", "output.jpg", quality=80)
圆角处理
# 普通圆角
rounded_img = LeviCanvas.get_round_image(img, radius=20)
# 自定义圆角(左上、右上、左下、右下)
rounded_img = LeviCanvas.get_round_imageEx(img, radius=20, type=(1, 1, 0, 0))
# 纯色圆角矩形
color_rect = LeviCanvas.get_solidColorRound_image(200, 100, (255, 0, 0), radius=10)
圆形图片
# 创建圆形图片
circular_img = LeviCanvas.get_circular_image(img, radius=100)
图片缩放
# 等比例缩放,自动填充空白
resized_img = LeviCanvas.zoom_img(img, width=500, height=300, alpha=True)
图形绘制
半透明区域
# 在图片上创建半透明区域
translucent_img = LeviCanvas.get_translucent_area(
img,
area=(10, 10, 100, 100), # (x1, y1, x2, y2)
color=(255, 0, 0, 128), # RGBA
_radius=10
)
渐变图片
# 创建渐变图片
gradient_img = LeviCanvas.get_gradient_image(
width=200,
height=100,
start_color=(255, 0, 0),
end_color=(0, 0, 255),
direction=1 # 1:左到右, 2:上到下, 3:左上到右下, 4:左下到右上
)
文本处理
基本文本绘制
font = ImageFont.truetype("arial.ttf", 24)
img = LeviCanvas.Draw_Text(img, font, (10, 10), (0, 0, 0), "Hello World")
居中文本
# 在指定区域内居中显示文本
img = LeviCanvas.Draw_TextMax(
img,
font,
area=(0, 0, 200, 100), # (x, y, width, height)
color=(0, 0, 0),
text="Centered Text"
)
高级文本处理
# 多行文本,自定义间距和对齐方式
img = LeviCanvas.Draw_TextMaxEX(
img,
font,
area=(0, 0, 200, 100),
clearance=5, # 行间距
color=(0, 0, 0),
text="Line 1\nLine 2\nLine 3",
mid=True # 居中显示,False为左对齐
)
进度条
线性进度条
font = ImageFont.truetype("arial.ttf", 24)
img = LeviCanvas.draw_progress_bar(
img,
font=font,
progress=0.75, # 0.0-1.0
text="75%",
area=(50, 50, 250, 100), # (x1, y1, x2, y2)
auto=True # 自动根据进度值变色
)
圆环进度条
img = LeviCanvas.draw_circle_outline(
img,
font=font,
progress=0.6, # 0.0-1.0
text="60%",
point=(200, 200), # 圆心坐标
radius=100,
thickness=20,
auto=True # 自动根据进度值变色
)
二维码生成
普通二维码
# 基本二维码
qr_img = LeviCanvas.generate_qr_code("https://example.com")
# 自定义样式二维码
config = {
"version": 1,
"box_size": 10,
"border": 2,
"fill_color": "black",
"back_color": "white"
}
qr_img = LeviCanvas.generate_qr_code("https://example.com", config=config)
带头像的二维码
# 生成带头像的二维码
qr_with_logo = LeviCanvas.generate_qr_code_with_logo(
"https://example.com",
config=config,
logo_path="logo.png"
)
特效处理
高斯模糊
# 对指定区域应用高斯模糊
blurred_img = LeviCanvas.apply_gaussian_blur(
img,
box=(50, 50, 150, 150), # (left, upper, right, lower)
radius=10
)
透明渐变
# 从指定位置开始透明渐变
gradient_img = LeviCanvas.grad_transparent_rectangle(img, y_begin=100)
