C++ (Cpp) Color::ToCOLORREF Examples

Example #1

File: Utils.cpp Project: vladios13/image-uploader

// hack for stupid GDIplus
void Gdip_RemoveAlpha(Gdiplus::Bitmap& source, Gdiplus::Color color )
{
	using namespace Gdiplus;
	Rect r( 0, 0, source.GetWidth(),source.GetHeight() );
	BitmapData  bdSrc;
	source.LockBits( &r,  ImageLockModeRead , PixelFormat32bppARGB,&bdSrc);

	BYTE* bpSrc = (BYTE*)bdSrc.Scan0;

	//bpSrc += (int)sourceChannel;


	for ( int i = r.Height * r.Width; i > 0; i-- )
	{
		BGRA_COLOR * c = (BGRA_COLOR *)bpSrc;

		if(c->a!=255)
		{
			//c = 255;

			DWORD * d= (DWORD*)bpSrc;
			*d= color.ToCOLORREF();
			c ->a= 255;
		}
		bpSrc += 4;

	}
	source.UnlockBits( &bdSrc );
}

Example #2

File: TextRender.cpp Project: qingzhengzhuma/sumatrapdf

void TextRenderHdc::SetTextColor(Gdiplus::Color col) {
    CrashIf(!hdc);
    if (textColor.GetValue() == col.GetValue()) {
        return;
    }
    textColor = col;
    ::SetTextColor(hdc, col.ToCOLORREF());
}

Example #3

File: TextRender.cpp Project: qingzhengzhuma/sumatrapdf

void TextRenderGdi::SetTextColor(Gdiplus::Color col) {
    if (textColor.GetValue() == col.GetValue()) {
        return;
    }
    textColor = col;
    if (hdcGfxLocked) {
        ::SetTextColor(hdcGfxLocked, col.ToCOLORREF());
    }
}

Example #4

File: MainFrm.cpp Project: Rancho06/ProCppProjects

LRESULT CMainFrame::OnPenColor(WORD /*wNotifyCode*/, WORD /*wID*/, HWND /*hWndCtl*/, BOOL& /*bHandled*/)
{
	// allow users to choose an arbitrary pen color
	Gdiplus::Color currentColor;
	m_view.m_Pen.GetColor(&currentColor);
	COLORREF color = currentColor.ToCOLORREF();
	CColorDialog test(color);
	test.DoModal();
	color = test.GetColor();
	Gdiplus::Color newColor(GetRValue(color), GetGValue(color), GetBValue(color));
	m_view.m_Pen.SetColor(newColor);
	return 0;
