  • begin_line
    Starts drawing a list of lines
  • begin_loop
    Starts drawing a closed sequence of lines

    Starts drawing a list of points. Points are added to the list with fl_vertex()
  • begin_polygon
    Starts drawing a convex filled polygon
  • can_do_alpha_blending
    Checks whether platform supports true alpha blending for RGBA images

  • capture_surface
    Captures the image surface object and returns raw data. Example usage:

    Captures part of the window and returns raw data. Example usage:
  • char_width
    Returns the typographical width of a single character
  • clip_region

  • draw_image
    Draw an image into a widget. Requires a call to app::set_visual(Mode::Rgb8).unwrap(). Doesn’t support transparency, for that you would have to use RgbImage.
  • draw_image2⚠
    Draw an image into a widget. Requires a call to app::set_visual(Mode::Rgb8).unwrap(). A negative depth flips the image horizontally, while a negative line data flips it vertically. Allows passing a line-data parameter
