函数ProPrintExecute该怎么用才能将工程图打印到硬盘里
有没有人搞二次开发工程图打印的？函数ProPrintExecute该怎么用才能将工程图打印到硬盘里并保存为jpg格式的图片？我的代码如下：ProPath path;ProPlotPaperSize size =
{
A4_SIZE_PLOT
};
int width = 297;
int height = 210;
ProPrintSize papersize =
{
size,
(double)width,
(double)height
};
int slew = 0;
ProPrintPrinterOpts PrinterOpts =
{
"JPEG",
///File related options
PRO_B_TRUE,
PRINT_SAVE_SINGLE_FILE,
//name,
PRO_B_FALSE,
///Print command options
PRO_B_FALSE,
//path,
//path,
1,
///Printer specific options
PRO_B_TRUE,
PRO_B_FALSE,
PRO_B_FALSE,
(double)slew,
PRO_B_FALSE
};
ProPrintMdlOpts PrintMdlOpts =
{
&model,
3,
///Options available only with solid objects
PRO_B_TRUE,
///Options available only with drawing objects
PRO_B_TRUE,
PRO_B_TRUE,
PRO_B_TRUE,
PRO_B_FALSE,
//name,
PRINT_CURRENT_SHEET,
0
};
int scale = 1,label_height=0;
double ofset={0,0}, clip_area={{0.000000,0.000000},{1.000000,1.000000}};
ProPrintPlacementOpts PlaceOpts =
{
(double)scale,
ofset,
PRO_B_FALSE,
///options for clipping
PRO_B_TRUE,
PRO_B_TRUE,
PRO_B_TRUE,
///options for label
PRO_B_FALSE,
NULL//(double)label_height
};
ProPrintPrinterOptionsGet("JPEG",&PrinterOpts);
ProPrintMdlOptionsGet(&model,&PrintMdlOpts);
ProPrintPlacementOptionsGet(&PlaceOpts);
err = ProPrintExecute(w_id,&PrinterOpts,&PrintMdlOpts,&PlaceOpts);
编译没有问题，但就是打印不出来文件，请问各位大侠，我的代码哪里出问题了？
