Question

我正在使用Skia在BlackBerry 10平台上绘制文字。我无法将Condensed或Light样式应用于字体。

在Skia中，它只有 kNormal 的类型枚举， kBold ， kItalic 和 kBoldItalic 样式。

这些样式运作良好

skTypeface = SkTypeface::CreateFromName("Slate Pro", SkTypeface::kNormal);
skTypeface = SkTypeface::CreateFromName("Slate Pro", SkTypeface::kBold);
skTypeface = SkTypeface::CreateFromName("Slate Pro", SkTypeface::kItalic);
skTypeface = SkTypeface::CreateFromName("Slate Pro", SkTypeface::kBoldItalic);

但我需要使用Slate Pro字体的 Condensed 或 Light 样式在BB10设备中。

我尝试了所有这些组合，它导致 SIGSEGV 。

skTypeface = SkTypeface::CreateFromName("SlateProLight", SkTypeface::kNormal);
skTypeface = SkTypeface::CreateFromName("Slate Pro-Light", SkTypeface::kNormal);
skTypeface = SkTypeface::CreateFromName("Slate Pro - Light", SkTypeface::kNormal);
skTypeface = SkTypeface::CreateFromName("SlatePro Light", SkTypeface::kNormal);
skTypeface = SkTypeface::CreateFromName("Slate Pro Condensed", SkTypeface::kNormal);

Sooooo，我试图通过尝试直接加载系统字体来尝试另一种方法。但是，即使Font文件存在，loadedTypeface仍然是NULL，无法找出原因。

QString loadedFont="/usr/fonts/font_repository/monotype/SlatePro-Light.ttf";
SkTypeface *loadedTypeface = SkTypeface::CreateFromFile(loadedFont.toUtf8().constData());

QFile targetFile(loadedFont);

if(targetFile.exists())
{
     if(loadedTypeface!=NULL)
     {
          skTypeface = SkTypeface::CreateFromTypeface(loadedTypeface , SkTypeface::kNormal);
     }
     else //Fallback to Arial
     {
          skTypeface = SkTypeface::CreateFromName("Arial",SkTypeface::kNormal);
     }
}

有关如何使用字体的简明或 Light 样式的任何想法？谢谢
