示例1: width
/* draw the string s with current font, but stretch it to fit the given
width (a+d). We haven't implemented stretching, so i just center the character. */
void
CairoPainter::drawText(const DOMString &s, float w) {
float sw = stringWidth(s) + absx; // this can't be right
float hdiff = w - sw;
cairo_move_to(m_painter, hdiff/2+absx, absy);
cairo_show_text(m_painter, s.utf8());
}示例2: drawOutline
void
CairoPainter::drawText(const DOMString &s) {
if (debugdrawtext) {
drawOutline(stringWidth(s));
}
cairo_move_to(m_painter, absx, absy);
cairo_show_text(m_painter, s.utf8());
}示例3: stringWidth
void
CairoPainter::drawText(const DOMString &s, float w, float a, float d) {
float sw = stringWidth(s);
float hdiff = w-sw;
float fa = fontAscent();
float fd = fontDescent();
float vdiff = d-fd - a+fa;
cairo_move_to(m_painter, hdiff/2, vdiff/2);
cairo_show_text(m_painter, s.utf8());
}示例4: createAttribute
/* this function sets an attribute in a dictionary entry */
