Graphics

========

The graphics library provides a set of portable drawing

primitives. Drawing takes place in a separate window that is created

when Graphics.open_graph is called. It used to be distributed with

OCaml up to OCaml 4.08.

Documentation

-------------

The API is documented 

[here](https://ocaml.github.io/graphics/graphics/Graphics/index.html)

and as comments in the source file `src/graphics.mli`.

On Unix

-------

On Unix graphics uses the X11 windows system.

Here are the graphics mode specifications supported by

`Graphics.open_graph` on the X11 implementation of this library: the

argument to `Graphics.open_graph` has the format `"display-name

geometry"`, where display-name is the name of the X-windows display to

connect to, and geometry is a standard X-windows geometry

specification. The two components are separated by a space. Either can

be omitted, or both. Examples:

- `Graphics.open_graph "foo:0"`: connects to the display foo:0 and

  creates a window with the default geometry

- `Graphics.open_graph "foo:0 300x100+50-0"` connects to the display

  foo:0 and creates a window 300 pixels wide by 100 pixels tall, at

  location (50,0)

- `Graphics.open_graph " 300x100+50-0"` connects to the default

  display and creates a window 300 pixels wide by 100 pixels tall, at

  location (50,0)

- `Graphics.open_graph ""` connects to the default display and creates

  a window with the default geometry.

On Windows

----------

On Windows graphics uses the native Win32 API.

Examples

--------

The `examples/` directory contains a few examples. You can run them

with:

- `dune exec examples/graph_example.exe`

- `dune exec examples/graph_test.exe`

- `dune exec examples/sorts.exe`
