C++ (Cpp) bytesFromResource Examples

Example #1

File: fontContext.cpp Project: hextriclosan/tangram-es

bool FontContext::addFont(std::string _fontFile, std::string _name) {
    if (m_fonts.find(_name) != m_fonts.end()) {
        return true;
    }

    unsigned int dataSize;
    unsigned char* data = bytesFromResource(_fontFile.c_str(), &dataSize);
    m_font = fonsAddFont(m_fsContext, "droid-serif", data, dataSize);

    if (m_font == FONS_INVALID) {
        logMsg("[FontContext] Error loading font file %s\n", _fontFile.c_str());
        return false;
    }

    m_fonts[_name] = m_font;

    return true;
}

    unsigned int size;
