PROE强大的参数化建模能力在各种领域应用广泛。本文讨论三个函数：ProRasterFileWrite，ProIntf3DFileWrite和ProPDFExport
这三个函数的共同特点是导出模型，具体有所不同。ProRasterFileWrite导出图片；ProIntf3DFileWrite则侧重与各种三维图形格式的转换；ProPDFExport则把模型导出为PDF格式文件。
（1）ProRasterFileWrite
ProRasterFileWrite函数定义如下：
| ProError | ProRasterFileWrite | ( |
| int window_id | ||
| /* (In) | ||
| 导出窗口ID,当前窗口用ProWindowCurrentGet获得 | ||
| */ | ||
| ProRasterDepth depth | ||
| /* (In) | ||
| 像素类型：PRORASTERDEPTH_8；PRORASTERDEPTH_24 | ||
| */ | ||
| double width | ||
| /* (In) | ||
| 图片宽度多少 inches | ||
| */ | ||
| double height | ||
| /* (In) | ||
| 图片宽度多少 inches | ||
| */ | ||
| ProDotsPerInch dots_per_inch | ||
| /* (In) | ||
| 每个英寸多少像素PRORASTERDPI_100 = 100, PRORASTERDPI_200 = 200, PRORASTERDPI_300 = 300, PRORASTERDPI_400 = 400, PRORASTERDPI_500 = 500, PRORASTERDPI_600 = 600 | ||
| */ | ||
| ProRasterType type | ||
| /* (In) | ||
| 图形格式：PRORASTERTYPE_BMP, PRORASTERTYPE_TIFF, PRORASTERTYPE_EPS, PRORASTERTYPE_JPEG | ||
| */ | ||
| ProPath output_file | ||
| /* (In) | ||
| 文件名称，包含扩展名 | ||
| */ | ||
| ) | ||
这个函数用法很简单，就是把当前窗口打印出来，可以生成几种不同的图形格式：PRORASTERTYPE_BMP, PRORASTERTYPE_TIFF, PRORASTERTYPE_EPS, PRORASTERTYPE_JPEG。当然也可以用-1来代表当前窗口ID。
int id; ProWindowCurrentGet(&id); ProRasterFileWrite(id,PRORASTERDEPTH_24,100,100,PRORASTERDPI_100, PRORASTERTYPE_JPEG,L"out.jpeg"); 或者 ProRasterFileWrite(-1,PRORASTERDEPTH_24,100,100,PRORASTERDPI_100, PRORASTERTYPE_JPEG,L"out2.jpeg");
当然也可以根据模型handle来获取窗口：ProMdlWindowGet ( ProMdl mdl, int* window_id );
（2）ProIntf3DFileWrite
ProIntf3DFileWrite可以将模型导出成如下格式：
|
|
|
Type Constant |
|---|---|---|
函数定义如下:
| ProError | ProIntf3DFileWrite | ( |
| ProSolid solid | ||
| /* (In) | ||
| The solid model used for export. | ||
| */ | ||
| ProIntf3DExportType file_type | ||
| /* (In) | ||
| The type of output file to produce. | ||
| */ | ||
| ProPath output_file | ||
| /* (In) | ||
| The output file name to produce. Optionally, this includes the path for the file location. The filename should not include the file extension, this will be added automatically by Pro/ENGINEER. | ||
| */ | ||
| ProOutputAssemblyConfiguration configuration | ||
| /* (In) | ||
| Specifies the number and type of output files to produce. Users should check that this option is valid for the type of output specified in file_type by using the function ProOutputAssemblyConfigurationIsSupported(). If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this value is ignored by Pro/ENGINEER. | ||
| */ | ||
| ProSelection reference_csys | ||
| /* (In) | ||
| The reference coordinate system. If NULL, the system uses the default coordinate system. If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
| ProOutputBrepRepresentation brep_representation | ||
| /* (In) | ||
| The options that specify the type of representation to create. Users should check that these options are valid for the type of output specified in file_type by using the function ProOutputBrepRepresentationIsSupported(). If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
| ProOutputInclusion inclusion | ||
| /* (In) | ||
| The options for entity inclusion or exclusion in the output file(s). If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
| ProOutputLayerOptions layer_options | ||
| /* (In) | ||
| The options that specify how layers are to be output. If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
几点注意事项:
参数ProIntf3DExportType定义导出类型,有下面几种:
typedef enum pro_intf3d_export_type {
PRO_INTF_EXPORT_STEP = 1,
PRO_INTF_EXPORT_SET,
PRO_INTF_EXPORT_VDA,
PRO_INTF_EXPORT_IGES,
PRO_INTF_EXPORT_CATIA,
PRO_INTF_EXPORT_CATIA_MODEL,
PRO_INTF_EXPORT_SAT,
PRO_INTF_EXPORT_NEUTRAL,
PRO_INTF_EXPORT_CADDS,
PRO_INTF_EXPORT_CATIA_SESSION, /* Not currently supported; */
/* reserved for future use. */
PRO_INTF_EXPORT_PDGS, /* Not currently supported; */
/* reserved for future use. */
PRO_INTF_EXPORT_PARASOLID,
PRO_INTF_EXPORT_UG,
PRO_INTF_EXPORT_RESERVED,
PRO_INTF_EXPORT_CATIA_PART,
PRO_INTF_EXPORT_CATIA_PRODUCT
} ProIntf3DExportType;
请注意这个参数:ProOutputAssemblyConfiguration configuration
它定义了装配导出后的性质,可以将整个装配体定义为一个PART，或者将装配所包含的所有部件逐一导出，详细解释：
PRO_OUTPUT_ASSEMBLY_FLAT_FILE：表示将ASM当作PART处理，导出后整个ASM模型合并成一个PART。
PRO_OUTPUT_ASSEMBLY_SINGLE_FILE：将ASM文件导出，引用其其现有组成部件。
PRO_OUTPUT_ASSEMBLY_MULTI_FILES：将ASM文件导出，将其现有组成部件也一起逐个导出。
PRO_OUTPUT_ASSEMBLY_PARTS
可以用ProOutputAssemblyConfigurationIsSupported判断ProOutputAssemblyConfiguration是否对当前模型适应。
ProOutputBrepRepresentation brep_representation：如何表示导出的几何体，当作线，面或者体
先用ProOutputBrepRepresentationAlloc制造一个ProOutputBrepRepresentation
然后调用函数进行设置：
ProOutputBrepRepresentationFlagsSet(rep,
PRO_B_FALSE,//ProBoolean as_wireframe,
PRO_B_FALSE,//ProBoolean as_surfaces,
PRO_B_TRUE,//ProBoolean as_solid,
PRO_B_FALSE//ProBoolean as_quilts
);
结束后释放内存：ProOutputBrepRepresentationFree
ProOutputInclusion inclusion：规定一些辅助线，坐标系是否导出
用这个函数进行设置：ProOutputInclusionFlagsSet(lnc,
PRO_B_TRUE,//ProBoolean include_datums,
PRO_B_FALSE,//ProBoolean include_blanked,
PRO_B_FALSE//ProBoolean include_facetted
);
最好放掉内存：ProOutputInclusionFree
一个简单的例子如下：将当前的PRT或者ASM导出为.ps(PARASOLID)格式。
ProMdl mdl; ProOutputBrepRepresentation rep; ProOutputBrepRepresentationAlloc(&rep); ProOutputBrepRepresentationFlagsSet(rep, PRO_B_FALSE,//ProBoolean as_wireframe, PRO_B_FALSE,//ProBoolean as_surfaces, PRO_B_TRUE,//ProBoolean as_solid, PRO_B_FALSE//ProBoolean as_quilts ); ProBoolean pb; //检查输出选项是否支持 ProError er=ProOutputBrepRepresentationIsSupported(PRO_INTF_EXPORT_PARASOLID, rep,&pb); if (er!=PRO_TK_NO_ERROR||!pb) { AfxMessageBox("Not Support!"); return; } ProOutputInclusion lnc; ProOutputInclusionAlloc(&lnc); ProOutputInclusionFlagsSet(lnc, PRO_B_TRUE,//ProBoolean include_datums, PRO_B_FALSE,//ProBoolean include_blanked, PRO_B_FALSE//ProBoolean include_facetted ); ProOutputLayerOptions lop; ProOutputLayerOptionsAlloc(&lop); ProOutputLayerOptionsAutoidSet(lop, PRO_B_FALSE//auto_ids ); //当前PRT 或者 ASM ProMdlCurrentGet(&mdl); if (!mdl) { AfxMessageBox("no prt or asm avaiable"); return; }
//导出 ProIntf3DFileWrite((ProSolid)mdl, PRO_INTF_EXPORT_PARASOLID,//导出ps格式 L"new_ps_name",//不要带后缀名，会自动加上去 PRO_OUTPUT_ASSEMBLY_FLAT_FILE,//将ASM当作一个PART处理导出 NULL, rep, lnc, lop ); ProOutputBrepRepresentationFree(rep); ProOutputInclusionFree(lnc); ProOutputLayerOptionsFree(lop);
模型文件：
导出PS格式后：
（3）导出PDF文件
需要包含头文件#include <ProPDF.h>
主要函数有这么几个：
- ProPDFoptionsIntpropertySet()：设置int型参数值
-
ProPDFoptionsAlloc() ：产生一个ProPDFOptions对象，后面的属性设置和导出都需要ProPDFOptions作为输入
主要的属性对象如下：
typedef enum { PRO_PDFOPT_FONT_STROKE, /* Enum, ProPDFFontStrokeMode, default PRO_PDF_USE_TRUETYPE_FONTS */ PRO_PDFOPT_COLOR_DEPTH, /* Enum, ProPDFColorDepth, default PRO_PDF_CD_COLOR */ PRO_PDFOPT_HIDDENLINE_MODE, /* Enum, ProPDFHiddenLineMode, default PRO_PDF_HLM_DASHED */ PRO_PDFOPT_SEARCHABLE_TEXT, /* Boolean, default TRUE */ PRO_PDFOPT_RASTER_DPI, /* Int, Range 100 - 600, default 300 */ PRO_PDFOPT_LAUNCH_VIEWER, /* Boolean, default TRUE */ PRO_PDFOPT_LAYER_MODE, /* Enum, ProPDFLayerMode, default PRO_PDF_LAYERS_ALL */ PRO_PDFOPT_PARAM_MODE, /* Enum, ProPDFParamMode, default PRO_PDF_PARAMS_ALL */ PRO_PDFOPT_HYPERLINKS, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_ZONES, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_VIEWS, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_SHEETS, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_FLAG_NOTES, /* Boolean, default TRUE */ PRO_PDFOPT_TITLE, /* String, default "" */ PRO_PDFOPT_AUTHOR, /* String, default <current user name> */ PRO_PDFOPT_SUBJECT, /* String, default "" */ PRO_PDFOPT_KEYWORDS, /* String, default "" */ PRO_PDFOPT_PASSWORD_TO_OPEN, /* String, default NULL, which means that the document may be opened by anyone */ PRO_PDFOPT_MASTER_PASSWORD, /* String, default NULL, which means that anyone may perform any change regardless of any of the modification flags PRO_PDFOPT_ALLOW_* listed below */ PRO_PDFOPT_RESTRICT_OPERATIONS, /* Boolean, default FALSE set to TRUE to use PRO_PDFOPT_ALLOW_* to use ProPDFRestrictOperationsMode */ PRO_PDFOPT_ALLOW_PRINTING, /* Boolean, default TRUE */ PRO_PDFOPT_ALLOW_PRINTING_MODE, /* Enum, ProPDFPrintingMode, default PRO_PDF_PRINTING_HIGH_RES */ PRO_PDFOPT_ALLOW_MODE, /* Enum, ProPDFRestrictOperationsMode, default PRO_PDF_RESTRICT_NONE */ PRO_PDFOPT_ALLOW_COPYING, /* Boolean, default TRUE */ PRO_PDFOPT_ALLOW_ACCESSIBILITY /* Boolean, default TRUE allows visually impaired screen reader devices to extract data independent of RestrictOperationsMode */ } ProPDFOptionType;
示例代码如下：
ProPDFOptions ops; ProPDFoptionsAlloc(&ops); //use ProPDFoptionsBoolpropertySet() and ProPDFoptionsStringpropertySet() //to set property //............... ProMdl mdl; ProMdlCurrentGet(&mdl); if (!mdl) { AfxMessageBox("no prt or asm avaiable"); return; } ProPDFExport(mdl,L"obj.pdf", ops); ProPDFoptionsFree(ops);
