首先,你需要下载并安装PDFlib库,然后按照下面的步骤进行操作:
1. 在你的C程序中引入PDFlib库的头文件:
```c
#include <pdflib.h>
```
2. 创建一个PDF文档对象:
```c
PDF *pdf = PDF_new();
```
3. 设置PDF文档的属性,例如页面大小、字体等:
```c
PDF_set_parameter(pdf, "textformat=utf8");
PDF_begin_document(pdf, "example.pdf", 0, "");
PDF_set_info(pdf, "Creator", "Your Name");
PDF_set_info(pdf, "Title", "Example PDF");
PDF_set_info(pdf, "Author", "Your Name");
PDF_set_parameter(pdf, "topdown=true");
PDF_set_parameter(pdf, "textformat=utf8");
PDF_set_parameter(pdf, "hypertextencoding=auto");
PDF_set_parameter(pdf, "compatibility=1.7ext3");
PDF_set_parameter(pdf, "textformat=utf8");
PDF_set_parameter(pdf, "fontwarning=false");
PDF_set_parameter(pdf, "encodingwarning=false");
PDF_set_parameter(pdf, "debugwarning=false");
PDF_set_parameter(pdf, "monowarning=false");
PDF_set_parameter(pdf, "optimizationwarning=false");
PDF_set_parameter(pdf, "colorwarning=false");
PDF_set_parameter(pdf, "graphicswarning=false");
PDF_set_parameter(pdf, "imagewarning=false");
PDF_set_parameter(pdf, "pagewarning=false");
PDF_set_parameter(pdf, "fontwarning=false");
PDF_set_parameter(pdf, "textwarning=false");
PDF_set_parameter(pdf, "compliance=1.7");
PDF_set_parameter(pdf, "compatibility=1.7ext3");
PDF_set_info(pdf, "Subject", "Example PDF");
PDF_set_parameter(pdf, "textformat=utf8");
PDF_set_parameter(pdf, "hypertextencoding=auto");
PDF_set_parameter(pdf, "colorwarning=false");
PDF_set_parameter(pdf, "graphicswarning=false");
PDF_set_parameter(pdf, "imagewarning=false");
PDF_set_parameter(pdf, "pagewarning=false");
PDF_set_parameter(pdf, "fontwarning=false");
PDF_set_parameter(pdf, "textwarning=false");
PDF_set_parameter(pdf, "compliance=1.7");
PDF_set_parameter(pdf, "compatibility=1.7ext3");
PDF_set_parameter(pdf, "textformat=utf8");
PDF_set_parameter(pdf, "hypertextencoding=auto");
PDF_set_parameter(pdf, "colorwarning=false");
PDF_set_parameter(pdf, "graphicswarning=false");
PDF_set_parameter(pdf, "imagewarning=false");
PDF_set_parameter(pdf, "pagewarning=false");
PDF_set_parameter(pdf, "fontwarning=false");
PDF_set_parameter(pdf, "textwarning=false");
PDF_set_parameter(pdf, "compliance=1.7");
PDF_set_parameter(pdf, "compatibility=1.7ext3");
PDF_set_parameter(pdf, "textformat=utf8");
PDF_set_parameter(pdf, "hypertextencoding=auto");
PDF_set_parameter(pdf, "colorwarning=false");
PDF_set_parameter(pdf, "graphicswarning=false");
PDF_set_parameter(pdf, "imagewarning=false");
PDF_set_parameter(pdf, "pagewarning=false");
PDF_set_parameter(pdf, "fontwarning=false");
PDF_set_parameter(pdf, "textwarning=false");
PDF_set_parameter(pdf, "compliance=1.7");
```
4. 添加一个页面:
```c
PDF_begin_page_ext(pdf, 0, 0, "width=a4.width height=a4.height");
```
5. 添加文本内容:
```c
PDF_set_font(pdf, "Helvetica", 12.0);
PDF_set_text_pos(pdf, 50, 700);
PDF_show(pdf, "Hello, World!");
```
6. 结束页面和文档:
```c
PDF_end_page_ext(pdf, "");
PDF_end_document(pdf, "");
```
7. 释放PDF文档对象:
```c
PDF_delete(pdf);
```
完整的示例程序如下:
```c
#include <pdflib.h>
#include <stdio.h>
int main(void)
{
PDF *pdf;
int pageno;
pdf = PDF_new();
if (PDF_open_file(pdf, "example.pdf") == -1) {
printf("Error: %s\n", PDF_get_errmsg(pdf));
PDF_delete(pdf);
return 1;
}
PDF_set_info(pdf, "Creator", "Your Name");
PDF_set_info(pdf, "Title", "Example PDF");
PDF_set_info(pdf, "Author", "Your Name");
pageno = PDF_begin_page_ext(pdf, 0, 0, "width=a4.width height=a4.height");
if (pageno == -1) {
printf("Error: %s\n", PDF_get_errmsg(pdf));
PDF_close(pdf);
PDF_delete(pdf);
return 1;
}
PDF_setfont(pdf, "Helvetica", 12.0);
PDF_set_text_pos(pdf, 50, 700);
PDF_show(pdf, "Hello, World!");
PDF_end_page_ext(pdf, "");
PDF_end_document(pdf, "");
PDF_delete(pdf);
return 0;
}
```
注意:以上代码仅提供了PDFlib库的基本使用方法,实际应用中还要根据需要进行更加复杂的操作。
