◆ layout_latex()

void TeXView::TeXArea::layout_latex ( ) const

MicroTeX: just run the LaTeX layout algorithms, do not draw.

◆ on_draw()

◆ on_size_allocate()

void TeXView::TeXArea::on_size_allocate ( Gtk::Allocation &  allocation)
overrideprotected

◆ set_latex()

void TeXView::TeXArea::set_latex ( const std::string &  latex)

MicroTeX: set the LaTeX string and replace/substitute so that MicroTeX can render it (but do not actually render).

◆ update_image()

void TeXView::TeXArea::update_image ( std::shared_ptr< TeXEngine::TeXRequest content,
double  scale 
)

Update the visible image from the pixbuf.

Call this in order to propagate changes to the pixbuf (e.g. from re-running the TeXRequest) to the visible widget itself.
