广告图片生成器使用说明
软件功能
这是一个用于生成广告图片的工具，可以快速制作包含产品图片和文字的广告图片。
主要特点
自定义广告尺寸（默认620×420像素）
智能去除产品图片背景
自动排版（左文右图布局）
自动文字换行
可自定义颜色和文字
使用步骤
1. 基本设置
广告尺寸: 可设置宽度（300-1920px）和高度（200-1080px）
广告文本: 在文本框中输入需要显示的广告文字
输出路径: 默认为"D:\PIC"，可通过"选择路径"按钮更改
2. 图片处理
选择图片: 点击"选择产品图片"按钮选择要使用的图片
去背景功能:
可通过复选框开启/关闭去背景功能
使用滑动条调整去背景阈值（180-250）
点击"预览去背景"查看效果
3. 样式设置
背景颜色: 点击"选择背景颜色"按钮自定义背景色
文字颜色: 点击"选择文字颜色"按钮自定义文字颜色
4. 生成和保存
生成预览: 所有设置完成后会自动预览效果
生成图片: 点击"生成广告图片"按钮生成最终图片
保存图片: 点击"保存图片"按钮将图片保存到指定位置
布局说明
文字区域占图片宽度的1/3，位于左侧
产品图片占图片宽度的2/3，位于右侧
文字和图片都会自动居中对齐
注意事项
去背景功能最适合处理白色或浅色背景的图片
文字会根据区域大小自动换行
图片会自动等比例缩放以适应区域
每次生成的图片会自动以时间戳命名
系统要求
操作系统：Windows
Python环境
需要安装的库：
PySide6
Pillow (PIL)
快捷操作
可以直接拖拽图片到软件窗口
使用滑动条快速调整去背景效果
实时预览所有修改效果
