有一個GDI的StrokePath API可以允許使用this method模擬「撫摸」文本。我使用的是DrawString功能從GDI +繪製文本如何在使用GDI +中的DrawString函數繪製文本時描邊文本?
void CCanvas::DrawOutlineText(CDC& dc, const CString& Text)
{
const int RestorePoint = dc.SaveDC();
// Create new font
CFont NewFont;
NewFont.CreatePointFont(700, TEXT("Verdana"), &dc);
// Use this font
dc.SelectObject(&NewFont);
// Brush for pen
LOGBRUSH lBrushForPen = { 0 };
lBrushForPen.lbColor = RGB(200, 150, 100);
lBrushForPen.lbHatch = HS_CROSS;
lBrushForPen.lbStyle = BS_SOLID;
// New pen for drawing outline text
CPen OutlinePen;
OutlinePen.CreatePen(PS_GEOMETRIC | PS_SOLID, 2, &lBrushForPen, 0, 0);
// Use this pen
dc.SelectObject(&OutlinePen);
dc.SetBkMode(TRANSPARENT);
dc.BeginPath();
// This text is not drawn on screen, but instead each action is being
// recorded and stored internally as a path, since we called BeginPath
dc.TextOut(20, 20, Text);
// Stop path
dc.EndPath();
// Now draw outline text
dc.StrokePath();
dc.RestoreDC(RestorePoint);
}
在我的情況:我會在這裏複製。
有沒有人知道是否有替代BeginPath
,EndPath
和StrokePath
在GDI +模擬文本撫摸?
編輯:繼以下jschroedl
的建議,我試過如下:
CString str = L"Text";
Graphics grpx(dc.GetSafeHdc());
SolidBrush gdiBrush(Color(0xFF, 0xFF, 0, 0));
StringFormat gdiSF;
gdiSF.SetAlignment(StringAlignmentNear);
gdiSF.SetFormatFlags(StringFormatFlagsNoWrap | StringFormatFlagsNoFitBlackBox |
StringFormatFlagsNoFontFallback | StringFormatFlagsNoClip);
gdiSF.SetHotkeyPrefix(HotkeyPrefixNone);
gdiSF.SetTrimming(StringTrimmingNone);
grpx.SetTextRenderingHint(TextRenderingHintAntiAlias);
grpx.SetPixelOffsetMode(PixelOffsetModeNone);
grpx.SetInterpolationMode(InterpolationModeHighQualityBicubic);
GraphicsPath dd;
FontFamily gdiFF(L"Segoe UI");
const PointF pntF(0, 0);
dd.AddString(str, str.GetLength(), &gdiFF, FontStyleRegular, 58.0f, pntF, &gdiSF);
Pen penFF(Color(0xFF, 0xFF, 0, 0), 1.0f);
grpx.DrawPath(&penFF, &dd);
所產生相當輪廓鋸齒(擴大截圖):
任何想法如何使它與抗鋸齒渲染?
嗯。有趣。謝謝。只是好奇,如果有一種方法來添加消除鋸齒畫筆。它看起來很矮胖。 – c00000fd
看看我們的代碼,我們似乎使用SetInterpolationMode(InterpolationModeHighQualityBicubic)在Graphics對象上設置了它,並且在我們調用graphics-> SetTextRenderingHint(TextRenderingHintAntiAlias)之前,有一條關於尋址'blocky text'的註釋:然後SetPixelOffsetMode(PixelOffsetModeNone) – jschroedl
你知道它沒有改變任何東西。查看我更新的原始帖子w/code。 – c00000fd
