我无法使用尖锐的 DX 计算 glyphRun 的宽度。下面是我用来呈现 glyphRun 的代码,字符串需要呈现为 char,如下所示。
private void RenderGlyphRun(FontFace fontFace)
{
GlyphRun glyphRun = new GlyphRun();
glyphRun.FontFace = fontFace;
glyphRun.FontSize = 23;
left = 50;
top = 50;
string word = "Hello World";
foreach (char letter in word)
{
string stringToBeRendered = letter.ToString();
int[] codePoints = new int[stringToBeRendered.Length];
char[] charsToBeRendered = stringToBeRendered.ToCharArray();
for (int i = 0; i < charsToBeRendered.Length; i++)
{
codePoints[i] = (int)charsToBeRendered[i];
}
short[] glyphIndices = fontFace.GetGlyphIndices(codePoints);
glyphRun.Indices = glyphIndices;
var BrushColor = SharpDX.Color.Black;
SharpDX.DirectWrite.Matrix mtrx = new SharpDX.DirectWrite.Matrix();
mtrx.M11 = 1F;
mtrx.M12 = 0;
mtrx.M21 = 0;
mtrx.M22 = 1F;
mtrx.Dx = 0;
mtrx.Dy = 0;
GlyphMetrics[] metrics = fontFace.GetGdiCompatibleGlyphMetrics(23, 1, mtrx, false, glyphIndices, false);
FontMetrics metr = fontFace.GetGdiCompatibleMetrics(23, 1, new SharpDX.DirectWrite.Matrix());
_pRenderTarget.DrawGlyphRun(new SharpDX.DrawingPointF(left, top), glyphRun, new SharpDX.Direct2D1.SolidColorBrush(_pRenderTarget, BrushColor), MeasuringMode.GdiClassic);
left += (metrics[0].AdvanceWidth - metrics[0].RightSideBearing + metrics[0].LeftSideBearing) / 100;
}
}
渲染字符串中的字符间距非常不同。请帮我解决一下这个。
