Save as Image

[ Edited ]

 

Hello,

i need an urgent help, before i will lose my mind! Smiley Happy

actually i want to do a simple thing, get a draft document and save it as tif file, in order to do that i must use the save as image method- which applied only for "view object", and "sheet metal"

i have a draft document, i tryed to reach both object-sheetmetal and view but i cant.

i get stuck in the windows collection- returns idispatch- and i need a window .

please view the code bellow...(it wont work cause i try to insert the idispatch into the windowptr)

 

DraftDocumentPtr drafDoc = doc;

WindowsPtr windows = drafDoc->Windows;

IDispatchPtr window = windows->Item((

long)1);

WindowPtr windowp= window;

ViewPtr view = windowp->View;

view->SaveAsImage(tiffFileName,0,0,0,0,0,seImageQualityHigh,VARIANT_FALSE);

please any ideas????

See CopyEmfToClipboard and .NET Discussion.  Basically you want to use the CopyEmfToClipboard function.  Search the forums for that keyword as well as the SDK for documentation.

Here is the example.

You will have to figure out how to get it to the image type that you want from there.

There is plenty of room for improvement on this code but it gets the point across.  I attached the solution to the post so you would have everything.// ExtractDraftImages.cpp : Defines the entry point for the console application.//#include "stdafx.h"bool GetEncoderClsid(const GUID FormatID, CLSID* pClsid){ UINT num, size; Gdiplus::GetImageEncodersSize(&num, &size); Gdiplus::ImageCodecInfo* pImageCodecInfo = (Gdiplus::ImageCodecInfo*)(malloc(size)); Gdiplus::GetImageEncoders(num, size, pImageCodecInfo); bool found = false; for (UINT ix = 0; !found && ix ActiveDocument; pSections = pDraftDocument->Sections; pSection = pSections->WorkingSection; pSectionSheets = pSection->Sheets; for (LONG i = 1; i Count; i++) { pSheet = pSectionSheets->Item(i); /* Copy EMF to Clipboard */ hr = pSheet->CopyEMFToClipboard(); /* Ensure EMF format is available */ if (IsClipboardFormatAvailable(CF_ENHMETAFILE)) { if (OpenClipboard((HWND)LongToHandle(pApplication->hWnd))) { /* Clipboard controls the handle! */ HENHMETAFILE hEmf = (HENHMETAFILE)GetClipboardData(CF_ENHMETAFILE); if (hEmf) { /* Gdiplus::Metafile */ Metafile metaFile(hEmf); CLSID encoder; if (!GetEncoderClsid(Gdiplus::ImageFormatTIFF, &encoder)) return E_FAIL; TCHAR szPath[MAX_PATH]; PathCombine(szPath, _T("C:\\"), pSheet->Name); PathAddExtension(szPath, _T(".tiff")); Gdiplus:Smiley Frustratedtatus status = metaFile.Save(szPath, &encoder); if (status == Gdiplus:Smiley Surprisedk) return E_FAIL; } CloseClipboard(); } } } /* Shut down Gdiplus */ Gdiplus::GdiplusShutdown(gdiplusToken); } pSheet = NULL; pSectionSheets = NULL; pSection = NULL; pSections = NULL; pDraftDocument = NULL; pApplication = NULL; CoUninitialize(); return 0;}

Hey

 

First- Thank you so much! you are such a big help....

 

i have one last question, i search the web and find it could mean so many things ...

in the

metaFile.Save(szPath, &encoder);

i get a genericerror.

too general, i saw on forums this could mean a graphic issue, or lots of other things...

 

do you know maybe why do i get that error?

 

Thanks!!!!!

I've read that permission issues is the most common cause. My example is writing to C:\. Does you app have rights to write a file there? Are you using Vista with UAC enabled?

 

I just noticed that: if (status == Gdiplus:Smiley Surprisedk) return E_FAIL;

is wrong. Don't return at that point because you need the Gdiplus::GdiplusShutdown(gdiplusToken);

to execute.

Hi Jasson,

this link does not work.
http://www.jasonnewell.net/Portals/0/NTForums_Attach/CopyEMF.zip
Can you send me a new link.

Thank you.

Re: RE: Save as Image

Dang, I can't find it either...

 

I'll rewrite the example and post a reply here with a link to the source. Which language are you needing?
