PXCV_DrawPageToDC and MM_ANISOTROPIC hDC MapMode

[Vitaly111]

Dear Sirs.
Could you help me?

I use MM_ANISOTROPIC hDC Map Mode for drawing in my application;
I'll try to use PXCV_DrawPageToDC in that mode... but unsuccessfully.
Can I use PXCV_DrawPageToDC in MM_ANISOTROPIC mode or only MM_TEXT mode?

Hi Vitaly,

I think you have posted in the wrong product topic, are you using the ActiveX Viewer SDK?

Hi!
I use C++ PDF Viewer SDK.( PDF-XChange Viewer Pro SDK 2.056 SDK Base Pack )

So still have a problem with MM_ANISOTROPIC MapMode - I have black square instead PDFPage bitmap. Even if I use correct LPtoDP, DPtoLP... etc transformation.
When I use MM_TEXT mode all is OK and PDFPage draw to offscreen DC.

Hello Vitaly,

Can you please try with the latest SDK build (2.5.189) and see if the problem still exists?

Best,
Stefan

Hi,Stefan.
I've just try to add some lines of code:

Code: Select all

...
          //the calculation of the size Page in  custom  hDC   dimension 
           double fcx=0;
	double fcy=0;
	if (curDoc)
	{
		if (IS_DS_SUCCESS(PXCV_GetPageDimensions(curDoc,nPageNum,&fcx,&fcy)))
		{
			m_PageSize.cx=MulDiv(int(fcx),100,72);
			m_PageSize.cy=MulDiv(int(fcy),100,72);
		}

		
	}

...


...
           // mapping mode is MM_ANISOTROPIC
	// these extents setup a mode similar to MM_LOENGLISH
	// MM_LOENGLISH is in .01 physical inches
	// these extents provide .01 logical inches

	pDC->SetMapMode(MM_ANISOTROPIC);
	pDC->SetViewportExt(pDC->GetDeviceCaps(LOGPIXELSX), pDC->GetDeviceCaps(LOGPIXELSY));
	pDC->SetWindowExt(100, -100);

	// set the origin of the coordinate system to the center of the page
	CPoint ptOrg;
	ptOrg.x = GetDocument()->m_PageSize.cx/2;
	ptOrg.y = GetDocument()->m_PageSize.cy/2;

	// ptOrg is in logical coordinates
	pDC->OffsetWindowOrg(-ptOrg.x,ptOrg.y);
...

                      PXV_CommonRenderParameters dp;
		dp.WholePageRect = (LPRECT)rcWindow;
		dp.DrawRect =(LPRECT)client;
		dp.Flags = 0;
		dp.RenderTarget = pxvrm_Viewing;
		hr=PXCV_DrawPageToDC(curDoc, 0, pDC->GetSafeHdc(), &dp);
		//pDC->Rectangle(client);

rcWindow= {top=550 bottom=-550 left=-425 right=425};
client = {top=550 bottom=-265 left=-425 right=408};

I had black square as result.
I've uncommented //pDC->Rectangle(client);
I have rectangle at right place;
