<![CDATA[GDI+ DrawImage malt wo es nicht soll!]]>Hmm ... also das Problem was hier auftritt ist, das obwohl Koordinaten für die Bitmap pPercentBitmapPart angegeben wurden der die einfach an die Stelle 0, 0 setzt. Jemand ne Idee?

Hier der Code:

Gdiplus::Pen pen(Gdiplus::Color(128, 128, 128));
		/************************************************************************/
		/*  Draw percent bar edges                                              */
		/************************************************************************/
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 - 55, rect.bottom - 30, (rect.right - rect.left) / 2 - 51, rect.bottom - 30);
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 - 50, rect.bottom - 35, (rect.right - rect.left) / 2 - 50, rect.bottom - 31);
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 + 55, rect.bottom - 30, (rect.right - rect.left) / 2 + 51, rect.bottom - 30);
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 + 50, rect.bottom - 35, (rect.right - rect.left) / 2 + 50, rect.bottom - 31);
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 + 55, rect.bottom - 20, (rect.right - rect.left) / 2 + 51, rect.bottom - 20);
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 + 50, rect.bottom - 15, (rect.right - rect.left) / 2 + 50, rect.bottom - 19);
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 - 55, rect.bottom - 20, (rect.right - rect.left) / 2 - 51, rect.bottom - 20);
		pMemGraphics->DrawLine(&pen, (rect.right - rect.left) / 2 - 50, rect.bottom - 15, (rect.right - rect.left) / 2 - 50, rect.bottom - 19);
		/************************************************************************/

		brush.SetColor(Gdiplus::Color(255, 255, 255));
		Gdiplus::Bitmap*	pMemBitmapPercent		= new Gdiplus::Bitmap(114, 10);
		Gdiplus::Graphics*	pMemGraphicsPercent		= Gdiplus::Graphics::FromImage(pMemBitmap);

		for (unsigned short percent = 0; percent < (100 / 7); ++percent)
		{
			Gdiplus::GraphicsPath* path = new Gdiplus::GraphicsPath;
			path->AddLine((percent * 7) + 10, 0, (percent * 7) + 5, 0);		// top right	=> top left
			path->AddLine((percent * 7) + 10 + 5, 0, (percent * 7) + 5, 9);	// top right	=> bottom right
			path->AddLine((percent * 7) + 5, 9, (percent * 7), 9);			// bottom right	=> bottom left
			path->AddLine((percent * 7) + 10, 0, (percent * 7), 9);			// bottom left	=> top left
			pMemGraphicsPercent->FillPath(&brush, path);
			delete path;
		}
		Gdiplus::Rect percent_rect(4, 0, min(m_percent, 100), 10);
		Gdiplus::Bitmap* pPercentBitmapPart = pMemBitmapPercent->Clone(percent_rect, PixelFormatDontCare);
		pMemGraphics->DrawImage(pPercentBitmapPart, (rect.right - rect.left) / 2 - 50, rect.bottom - 29);
		delete pMemGraphicsPercent;
		delete pMemBitmapPercent;

		graphics.DrawImage(pMemBitmap, 0, 0);
		delete pMemBitmap;
		delete pMemGraphics;

... ok der Code istnoch nicht optimiert aber das ist ja auch nicht der Punkt 😉

pMemBitmapPercent muss es auch beim erstellen vom pMemGraphicsPercent heißen ^^
