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.
