C++ (Cpp) CacheCharacter Examples

Example #1

File: FreeTypeFontSystem.cpp Project: Deamonian/Spelprogrammering_2

int FontBuilder::FTSystem::CalcWidth(FTFont *font,int size,String *str) {
	int width=0;
	int len=str->length();
	for(int i=0;i<len;i++) {
		unsigned int c=(unsigned int)ubyte(str->at(i));
		if(c==32) {
			width+=size<<1;
			continue;
		};
		FTFont::GlyphEntry *e=font->FindCharIndex(c,size);
		if(!e) {
			CacheCharacter(font,c,size,Vector3(1.0f,1.0f,1.0f));
			e=font->FindCharIndex(c,size);
			if(!e) {e=font->FindCharIndex(ubyte('?'),size);};
		};
		width+=e->advx;
	};
	return width;
};

Example #2

File: GdiFont.cpp Project: liuwanbing/liuwanbing

// 根据字符获取轮廓
unsigned int GdiFont::GetGlyphByCharacter( wchar_t c )
{
	unsigned int idx = (unsigned int)c;
	if (NULL == (m_FontGlyphs[idx].t)) CacheCharacter(idx,c);
	return idx;
}
