QPixmap

Hello anyone

Iám using windows xp with qt-4.5.2
I have a application with QGLWidget and FTGL
I use this application for 3d font and its works fine.
Its works together with a .ttf file.
I have read the documentation FTGL and its only can be used for fonts or special fonts.

I want to use a Pixmap.
Is it possible to do this.
Must i convert the QPixmap to QBytearray? or something else QBuffer.

This is a piece of my implentation glwidget.cpp

Code:

---

// Set up the FTGL library for 3D text rendering
bool GLWidget::initFTGL() {
    font = new FTExtrudeFont("Arial.ttf");
    if (font->Error()) {
        qDebug("initFTGL(): Could not load font.");
        return false;
    }
    font->FaceSize(14);
    font->Depth(1.0f);
    return true;
}

---

In my paintGL()

Code:

---

void GLWidget::paintGL()
{
    ......
    QByteArray cStr = ( QVariant("img/s.png" ) ).toByteArray() ;
    FTBBox rect = font->BBox(cStr.data());
    FTPoint p = rect.Upper();
    glColor3f(0.0,0.0,0.0);
    glRotatef(rot, 0.0f, 1.0f, 0.0f);
    glTranslatef(-p.Xf() / 2.0f, -p.Yf() / 2.0f, 0.0f);
    font->Render(cStr.data());
}

I only see in my application the text img/s.png not the image


Thanks in advance.

I don't think you can render a pixmap using a font renderer, this seems to be a misunderstanding of either OpenGL or FTGL. But you can use an image as a texture and render it on some quad.

Thanks for your reply.
I have already an image as texture on a different cubes.
