Qt 讀取非系統字型
使用QFontDatabase::addApplicationFont，可以直接讀取字型 檔(ttc, ttf)。
#include <QFontDatabase>
QString loadFontFromFile(QString path)
{
static QString font;
static bool loaded = false;
if(!loaded)
{
loaded = true;
int loadedFontID = QFontDatabase::addApplicationFont(path);
QStringList loadedFontFamilies = QFontDatabase::applicationFontFamilies(loadedFontID);
if(!loadedFontFamilies.empty())
font = loadedFontFamilies.at(0);
}
return font;
}
QString fontName = loadFontFromFile(":/font/font2.TTC");
QFont font(fontName);
#include <QFontDatabase>
QString loadFontFromFile(QString path)
{
static QString font;
static bool loaded = false;
if(!loaded)
{
loaded = true;
int loadedFontID = QFontDatabase::addApplicationFont(path);
QStringList loadedFontFamilies = QFontDatabase::applicationFontFamilies(loadedFontID);
if(!loadedFontFamilies.empty())
font = loadedFontFamilies.at(0);
}
return font;
}
QString fontName = loadFontFromFile(":/font/font2.TTC");
QFont font(fontName);

3D text on Qt with OpenGL
利用QPainterPath算出polygon之後，就可以畫出邊框
QPainterPath path;
path.addText(QPointF(0, 0), QFont("Arial", 100), QString::fromUtf8("你要不要喝紅茶ˊ_>ˋ？"));
GLuint id = glGenLists(1);
glNewList(id, GL_COMPILE);
foreach(QPolygonF polygon, path.toSubpathPolygons()){
glBegin(GL_LINE_LOOP);
foreach(QPointF point, polygon){
glVertex3f(point.rx(), -point.ry(), 0);
}
glEnd();
}
glEndList();

html5版的馬賽克
利用 input type="file"選取本地端圖檔用FileReader的readAsDataURL讀取圖檔將圖畫到canvas用range來當sliderbar，注意firefox不支援range接下來就是拿canvas來做影像處理了最後，再利用canvas.toDataURL("image/jpeg")轉回圖檔 index.html
