以下是一个简单的使用mupdf库在Windows下开发的程序,可用于指定纸张和纸盒将PDF文件发送到打印机进行打印。
```c
#include <stdio.h>
#include <mupdf/fitz.h>
#include <windows.h>
// 打印机选项
#define PRINTER_NAME "Microsoft Print to PDF"
#define PAPER_SIZE DMPAPER_A4
#define PAPER_SOURCE DMBIN_AUTO
int main(int argc, char **argv)
{
// 加载PDF文件
char *filename = "example.pdf";
fz_context *ctx = fz_new_context(NULL, NULL, FZ_STORE_DEFAULT);
fz_document *doc = fz_open_document(ctx, filename);
if (!doc) {
printf("Failed to open document: %s\n", filename);
return 1;
}
// 获取第一页
fz_page *page = fz_load_page(doc, 0);
if (!page) {
printf("Failed to load page 1\n");
fz_close_document(doc);
fz_free_context(ctx);
return 1;
}
// 获取页面大小
fz_rect bbox;
fz_bound_page(doc, page, &bbox);
// 准备打印机
DOC_INFO_1 di = { 0 };
di.pDocName = "Print Document";
di.pOutputFile = NULL;
di.pDatatype = "RAW";
if (!OpenPrinter(PRINTER_NAME, &hPrinter, NULL)) {
printf("Failed to open printer\n");
fz_drop_page(doc, page);
fz_close_document(doc);
fz_free_context(ctx);
return 1;
}
StartDocPrinter(hPrinter, 1, (LPBYTE)&di);
StartPagePrinter(hPrinter);
// 设置打印参数
DOC_INFO_2 di2 = { 0 };
di2.pszPrinterName = PRINTER_NAME;
di2.pszDocName = "Print Document";
di2.pszOutputFile = NULL;
di2.pszDatatype = "RAW";
di2.pDevMode = NULL;
di2.fwType = 0;
if (!GetPrinter(hPrinter, 2, NULL, 0, &size_needed)) {
if (GetLastError() == ERROR_INSUFFICIENT_BUFFER) {
p_info = (PRINTER_INFO_2*)malloc(size_needed);
if (!GetPrinter(hPrinter, 2, (LPBYTE)p_info, size_needed, &size_needed)) {
printf("Failed to get printer info\n");
EndPagePrinter(hPrinter);
EndDocPrinter(hPrinter);
ClosePrinter(hPrinter);
fz_drop_page(doc, page);
fz_close_document(doc);
fz_free_context(ctx);
return 1;
}
di2.pDevMode = p_info->pDevMode;
}
}
// 设置纸张和纸盒
di2.pDevMode->dmFields |= DM_PAPERSIZE | DM_DEFAULTSOURCE;
di2.pDevMode->dmPaperSize = PAPER_SIZE;
di2.pDevMode->dmDefaultSource = PAPER_SOURCE;
// 打印页面
HDC hdc = CreateDC(NULL, PRINTER_NAME, NULL, di2.pDevMode);
fz_device *dev = fz_new_printer_device(ctx, hdc);
fz_matrix transform = fz_scale(72.0 / 300, 72.0 / 300);
fz_run_page(doc, page, dev, &transform, NULL);
fz_close_device(dev);
DeleteDC(hdc);
// 结束打印
EndPagePrinter(hPrinter);
EndDocPrinter(hPrinter);
ClosePrinter(hPrinter);
// 释放资源
fz_drop_page(doc, page);
fz_close_document(doc);
fz_free_context(ctx);
return 0;
}
```
该程序使用mupdf库加载PDF文件并获取第一页。然后,它使用Windows API打开指定的打印机,并根据指定的纸张和纸盒设置打印参数。接下来,它创建一个打印设备并使用该设备打印页面。最后,它关闭打印机并释放资源。
请注意,该程序仅提供了一个简单的示例,并且可能需要根据您的具体需求进行更改。特别是,您可能需要添加错误处理和异常情况处理以确保程序的稳定性和可靠性。
