a question of Export custom file format?
Hi My os is ms windows. I write a extention. In my extention how can I get openoffice program path. I want to Dynamic loading some dll. Who can tell me get the path method? My programming language use C++. Best regards.

Hi , On 07.06.2012 02:24, wrote: hi Armin can i modify the SDK to achieve my need. Not the SDK, but the UNO API definition and imlementation for primitives. You could do that in principle, but it is a lot of work and requires knowing the UNO API and it's principles, Primitives and their principles, some of the AOO code and it's functionalities and a lot of AOO-specific data types and how to handle them over the API. It also is a region where first design and then open discussion will be needed to guarantee a good API design; it would be intended to be used by everyone and (in principle) should never need to be changed (and needs to stay backward compatible from there on since it would be a public API). achieve demo code as below: Reference XRenderable xRenderable( mxSrcDoc, UNO_QUERY ) VCLXDevice* pXDevice = new VCLXDevice; .. PDFWriter* pPDFWriter = new PDFWriter( aURL.GetMainURL(INetURLObject::DECODE_TO_IURI), PDFWriter::PDF_1_4, eCompressMode ); OutputDevice* pOut = pPDFWriter-GetReferenceDevice(); pXDevice-SetOutputDevice( pOut ); .. GDIMetaFile aMtf; const MapMode aMapMode( MAP_100TH_MM ); const Size aMtfSize( aPageSize.Width, aPageSize.Height ); pOut-Push(); pOut-EnableOutput( FALSE ); pOut-SetMapMode( aMapMode ); aMtf.SetPrefSize( aMtfSize ); aMtf.SetPrefMapMode( aMapMode ); aMtf.Record( pOut ); xRenderable-render( nSel - 1, aSelection, aRenderOptions ); aMtf.Stop(); aMtf.WindStart(); if( aMtf.GetActionCount() ) bRet = ImplExportPage( *pPDFWriter, aMtf, nCompressMode ) || bRet; pOut-Pop(); just provide the output of the VCL. To meet my needs. If this idea can be. How do I do?

You cannot use this when you want to develop an extension, the UNO API for primitives is minimal currently and thus you would have to link against office components (what the definition of extension does not allow).

a question of Export custom file format?
Hi 蜗牛 You can modify the source code to be recompiled. Reference XRenderable xRenderable( mxSrcDoc, UNO_QUERY ) VCLXDevice* pXDevice = new VCLXDevice; .. PDFWriter* pPDFWriter = new PDFWriter( aURL.GetMainURL(INetURLObject::DECODE_TO_IURI), PDFWriter::PDF_1_4, eCompressMode ); OutputDevice* pOut = pPDFWriter-GetReferenceDevice(); pXDevice-SetOutputDevice( pOut ); .. GDIMetaFile aMtf; const MapMode aMapMode( MAP_100TH_MM ); const Size aMtfSize( aPageSize.Width, aPageSize.Height ); pOut-Push(); pOut-EnableOutput( FALSE ); pOut-SetMapMode( aMapMode ); aMtf.SetPrefSize( aMtfSize ); aMtf.SetPrefMapMode( aMapMode ); aMtf.Record( pOut ); xRenderable-render( nSel - 1, aSelection, aRenderOptions ); aMtf.Stop(); aMtf.WindStart(); if( aMtf.GetActionCount() ) bRet = ImplExportPage( *pPDFWriter, aMtf, nCompressMode ) || bRet; pOut-Pop(); Regards

hi Armin can i modify the SDK to achieve my need. achieve demo code as below: Reference XRenderable xRenderable( mxSrcDoc, UNO_QUERY ) VCLXDevice* pXDevice = new VCLXDevice; .. PDFWriter* pPDFWriter = new PDFWriter( aURL.GetMainURL(INetURLObject::DECODE_TO_IURI), PDFWriter::PDF_1_4, eCompressMode ); OutputDevice* pOut = pPDFWriter-GetReferenceDevice(); pXDevice-SetOutputDevice( pOut ); .. GDIMetaFile aMtf; const MapMode aMapMode( MAP_100TH_MM ); const Size aMtfSize( aPageSize.Width, aPageSize.Height ); pOut-Push(); pOut-EnableOutput( FALSE ); pOut-SetMapMode( aMapMode ); aMtf.SetPrefSize( aMtfSize ); aMtf.SetPrefMapMode( aMapMode ); aMtf.Record( pOut ); xRenderable-render( nSel - 1, aSelection, aRenderOptions ); aMtf.Stop(); aMtf.WindStart(); if( aMtf.GetActionCount() ) bRet = ImplExportPage( *pPDFWriter, aMtf, nCompressMode ) || bRet; pOut-Pop(); just provide the output of the VCL. To meet my needs. If this idea can be. How do I do?

It would be more or less the same as every UNO API based export, iterate over the document, the pages and the shapes. Instead of getting a MetaFile from the shape (using Graphicxporter) you would get the sequence of primitives and use that as base geometry information. You cannot use this when you want to develop an extension, the UNO API for primitives is minimal currently and thus you would have to link against office components (what the definition of extension does not allow). To do this, the most needed primitives would need to get an UNO API implementation first. Regards Sincerely, Armin -- ALG /:includetail
a question of Export custom file format?
HI: I need to develop an extension program of openoffice's write, the extended function is export a custom file format , the file format similar as PDF file format , But not the PDF file format. I analyzed the export of PDF files ,the Function through VCL output. I have two question as below: 1)Such need can be achieved in extension of openoffice's write? 2) Can I use calss VirtualDevice calss GDIMetaFile interface--- Reference XRenderable xRenderable (mxSrcDoc, UNO_QUERY) in openoffice's write?
