Description

Details

gnome_canvas_text_set_zoom_size ()

void        gnome_canvas_text_set_zoom_size (GnomeCanvasText *item,
                                             gdouble pixels);

Set the default font size in pixels of a canvas text item. The size will be adjusted when the canvas zoomed via gnome_canvas_set_zoom().

`item` :	canvas text item
`pixels` :	default font size

gnome_canvas_set_zoom ()

void        gnome_canvas_set_zoom           (GnomeCanvas *canvas,
                                             gdouble pixels_per_unit);

This function calls gnome_canvas_set_pixels_per_unit() with its arguments and in addition adjusts the font sizes of all canvas text items where gnome_canvas_text_set_zoom_size() was used before.

`canvas` :	valid GnomeCanvas
`pixels_per_unit` :	zoom factor (defaults to 1.0)
