Hello,

since some time, we don't know for sure since when, because an customer reported it, XTP Report Control stopped printing out icons, just an small dot is printed out.
We have v16.3 out at the customers, I tested here with 16.3 and 17.3 both have the same issue.
18.6 and 19.1 I have also here, but can't test as all the solution files are missing. Confused
Tested here with the Report Control Sample, unmodified, It also don't print out the Icons:

What is really interesting, Glyphs are printed out, everything else not:

Here the printout:

Tested it with several real printers, also PDF printers, all the same...
My System: Windows 10 x64 20H2 with all Updates installed.

Is anyone also have that error?
I tried to replace the report imagelist with glyphs image list, works well in the sample, but printout is the same...

Tried to debug the source, everything fine, no assertions, no errors, StretchBlt in the CXTPImageManagerResource::Draw Method returns true, so everything works fine, but still no Icons...

Any Ideas?

Greetings Jack

I found something out...

in the CXTPReportPaintManager::DrawItemBitmap Function, there is a difference between printing or not: 
	// draw image

	if (pDrawArgs->pDC->IsPrinting())
	{
		CBitmap bmp;
		bmp.CreateCompatibleBitmap(pDrawArgs->pDC, szImage.cx, szImage.cy);
		CXTPCompatibleDC dcMem(NULL, &bmp);
		dcMem.FillSolidRect(0, 0, szImage.cx, szImage.cy, pDrawArgs->pDC->GetBkColor());
 
		pIcon->Draw(&dcMem, CPoint(0, 0), pIcon->GetIcon());
		pDrawArgs->pDC->BitBlt(ptIcon.x, ptIcon.y, szImage.cx, szImage.cy, &dcMem, 0, 0, SRCCOPY);
	}
	else
	{
		pIcon->Draw(pDrawArgs->pDC, ptIcon, pIcon->GetIcon(), 0, pDrawArgs->pRow->IsSelected() ? GetXtremeColor(COLOR_HIGHLIGHT) : CLR_NONE, pDrawArgs->pRow->IsSelected() ? GetXtremeColor(COLOR_HIGHLIGHT) : CLR_NONE, pDrawArgs->pRow->IsSelected() ? ILD_SELECTED : 0);
	}


For printing out Glyphs, there is no difference and when I comment out the IsPrinting Block out, everything works fine.
So the question is, is that important? I tested on two printers plus PDF Printer, everything fine.
