egd - egd - erlang graphical drawer. DESCRIPTION
egd - erlang graphical drawer DATA TYPES
color() : egd_image() : font() : point() = {integer(), integer()} : render_option() = {render_engine, opaque} | {render_engine, alpha} : EXPORTS
color(Color::Value | Name) -> color() Types Value = {byte(), byte(), byte()} | {byte(), byte(), byte(), byte()} Name = black | silver | gray | white | maroon | red | purple | fuchia | green | lime | olive | yellow | navy | blue | teal | aqua Creates a color reference. create(Width::integer(), Height::integer()) -> egd_image() Creates an image area and returns its reference. destroy(Image::egd_image()) -> ok Destroys the image. filledEllipse(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok Creates a filled ellipse object. filledRectangle(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok Creates a filled rectangle object. line(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok Creates a line object from P1 to P2 in the image. rectangle(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok Creates a rectangle object. render(Image::egd_image()) -> binary() Equivalent to render(Image, png, [{render_engine, opaque}]) . render(Image::egd_image(), Type::png | raw_bitmap) -> binary() Equivalent to render(Image, Type, [{render_engine, opaque}]) . render(Image::egd_image(), Type::png | raw_bitmap, Options::[render_option()]) -> binary() Renders a binary from the primitives specified by egd_image(). The binary can either be a raw bitmap with rgb tripplets or a binary in png format. save(Binary::binary(), Filename::string()) -> ok Saves the binary to file. text(Image::egd_image(), P::point(), Font::font(), Text::string(), Color::color()) -> ok Creates a text object.
