So, it’s a very simple almost one-to-one translation of that C code block to Swift. You have to make sure to import CCairo at the beginning of the file, and change the variable declarations to use let instead of the C declaration.
This works for me, as is. import CCairo let surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 240, 80) let cr = cairo_create (surface); cairo_select_font_face(cr, "serif", CAIRO_FONT_SLANT_NORMAL, CAIRO_FONT_WEIGHT_BOLD) cairo_set_font_size(cr, 32.0) cairo_set_source_rgb(cr, 0.0, 0.0, 1.0) cairo_move_to(cr, 10.0, 50.0) cairo_show_text(cr, "Hello, world") cairo_destroy(cr) cairo_surface_write_to_png(surface, "hello.png") cairo_surface_destroy(surface) > On Dec 11, 2015, at 3:21 PM, Gage Morgan <gagemor...@outlook.com> wrote: > > Do so here in a few.
