# PdfConverter
文件转 Pdf 工具
## 使用说明
```pascal
alias := "";
doc := "D:\\temp\\wordtopdf\\3M.docx";
output := "D:\\temp\\1.pdf";
docx_to_pdf := new TSDocxToPdf(alias, doc);
docx_to_pdf.Font.SetSubstitutionRules("仿宋", "宋体");
docx_to_pdf.Transform();
err := docx_to_pdf.SaveToFile(alias, output);
echo "SaveToFile::\t", "err := ", format("%x", err), "\toutput_file := ", output, "\n";
```
TSDocxToPdf中的[Font](./ware/TSFontWare.tsf)属性是设置转PDF时的一些字体配置包含以下函数
- `SetDefaultSz(value: real);`设置默认字体大小Docx转Pdf会遇到获取默认字体大小失败情况此时可通过此方法设置字体大小。不设置情况下默认是10.5磅
- `SetSubstitutionRules(source: string; target: string);`:字体替换规则,遇到不支持的字体,需要设置替换的目标字体。未设置情况下会默认替换为宋体
- `UseExternalFont()`使用外部字体需要部署在fonts文件夹。暂不支持
当前默认使用的是Pdf内置的字体仅支持宋体和黑体
## 部署
将此文件夹部署到 tsl 安装目录下`funcext`即可
