.SH NAME
MiniLibX - Simple Window Interface Library for students
.SH SYNOPSYS

.nf
.I void *

.B mlx_init

(void *mlx_ptr);
.SH DESCRIPTION
MiniLibX is an easy way to create graphical software,
without any X-Window/Wayland/Vulkan programming knowledge under Unix/Linux,
nor any AppKit programming knowledge under MacOS. It provides
simple window creation, a drawing tool, image and basic events
management.
.SH Unix/Linux: HISTORICAL X-WINDOW CONCEPT
X-Window is a network-oriented graphical system for Unix.
It is based on two main parts:
.br
On one side, your software wants to draw something on the screen and/or
get keyboard & mouse entries.
.br
On the other side, the X-Server manages the screen, keyboard and mouse
(It is often referred to as a "display").
.br
A network connection must be established between these two entities to send
drawing orders (from the software to the X-Server), and keyboard/mouse
events (from the X-Server to the software).
.br
Nowadays, most of the time, both run on the same computer.
.SH Unix/Linux: MODERN GRAPHICAL APPROACH
Modern computers come with a powerful GPU that is directly accessed by applications.
Along GPU libraries like Vulkan or OpenGL, the Wayland protocol ensure communication
with the compositor program that manages the various windows on screen and the user
input events.
For your own application:
.br
The Vulkan or OpenGL library allow you to directly draw any content into your window.
.br
The Wayland compositor handles the place of your window on screen and send you back
the keyboard and mouse inputs from the user.
.br
Unfortunately, this gain of graphical power through GPU access removes the networking aspects
that exist with X-Window. It is not possible for a program to access a remote GPU and show its
window on a remote display. But current software architectures are more likely based on a local
display application that gets data in JSON through a web API.
.SH MacOS: WINDOW SERVER AND GPU
Your software interacts directly with the Window server who handles the
cohabitation on the screen with other software and the event system,
and interacts with the GPU to handle all drawing commands.
.SH INCLUDE FILE
.B mlx.h
should be included for a correct use of the MiniLibX API.
It only contains function prototypes, no structure is needed.
.SH LIBRARY FUNCTIONS
.P
First of all, you need to initialize the connection
between your software and the graphic and user sub-systems.
Once this completed, you'll be able to use other MiniLibX
functions to send and receive the messages from
the display, like "I want to draw a yellow pixel in this window" or
"did the user hit a key?".
.P
The
.B mlx_init
function will create this connection. No parameters are needed, ant it will
return a
.I "void *"
identifier, used for further calls to the library routines. The
.B mlx_release
function can be used at the end of the program to disconnect from the graphic
system and release resources.
.P
All other MiniLibX functions are described in the following man pages:
.TP 20
.B mlx_new_window
: manage windows
.TP 20
.B mlx_pixel_put
: draw inside a window
.TP 20
.B mlx_new_image
: manipulate images
.TP 20
.B mlx_loop
: handle keyboard or mouse events
.TP 20
.B mlx_extra
: extra functions available in the MinilibX
.SH LINKING MiniLibX
To use MiniLibX functions, you may -or not- need to link
your software with several libraries, including the MiniLibX library itself.
On Unix/Linux, depending on the specific operating system, either just using
.B -lmlx
works, or you need to add
.B -lxcb -lxcb-keysyms -lvulkan -lz -lbsd
\&.
On MacOS, the dynamic Metal library will find on its own the missing components:
.B -lmlx
\&.
You may also need to specify the path to these libraries, using the
.B -L
flag.
.SH RETURN VALUES
If
.B mlx_init()
fails to set up the connection to the display, it will return NULL, otherwise
a non-null pointer is returned as a connection identifier.

**
** This library is a simple framework to help 42 students
** create simple graphical apps.
** It only provides the minimum functions, it's students' job
** to create the missing pieces for their own project :)
**
** Current XCB-Vulkan requirements for Linux:
** libxcb, libxcb-keysyms, libvulkan,
** libz, libbsd
** You also need glslc to re-compile shaders if needed.
** At 42, on current Ubuntu 22.04 dump in cluster, you need to get
** libxcb-keysyms source for the include file and compile the .a library.
**
** The MinilibX can load XPM and PNG images.
** Please note that both image loaders are incomplete, some
** image may not load. Also, image loaders only work for little endian hosts.
**
** Historically, the alpha byte did represent transparency
** instead of opacity. It's not the case anymore. MLX matches GPUs standards.
**
** MLX_CLXV API changes:
** - mlx_get_data_addr now provides the image format instead of the
endian, and returns an 'unsigned char' pointer.
** - 'unsigned int' replace 'int' in many calls.
** - mlx_get_color_value() is now deprecated.
** - adding mlx_loop_exit().
**
** With recent X11 implementation and default configuration, the Expose event is only
** received once at the program launch. This is often due to X server saving the
** content of the window.
** With Wayland, there is no such thing like Expose event, and the compositor saves
** the window's content.

.SH MOUSE EXTRA FUNCTIONS
It is possible to show / hide the mouse, and get its current position without user click or
force its position inside a window.
.SH KEYBOARD EXTRA FUNCTIONS
The auto-repeat mode of the keyboard can be controlled. By default, auto-repeat is on:
multiple "key pressed" events are generated every second until the key is released.
.SH SCREEN EXTRA FUNCTION
It is possible to retrieve the size of the current screen, even before the first
window is created.
.SH FLUSH AND SYNC FUNCTIONS
The
.B mlx_do_sync
function will flush the pending commands to the graphic subsystems, ensuring nothing
is cached on your software's side. On return, there is no guarantee that your
commands have been processed.
.br
With
.B mlx_sync
you have more detailed control over the synchronisation mechanisms. Three different commands
are available:
.br
#define MLX_SYNC_IMAGE_WRITABLE 1
.br
#define MLX_SYNC_WIN_FLUSH 2
.br
#define MLX_SYNC_WIN_COMPLETED 3
.br
The third parameter
.I param
can be either the image identifier (command #1) or the window identifier (commands #2 and #3).

.SH EVENTS
The graphical system is bi-directional. On one hand, the program sends orders to
the screen to display pixels, images, and so on. On the other hand,
it can get information from the keyboard and mouse associated to
the screen. To do so, the program receives "events" from the keyboard or the
mouse.
.SH DESCRIPTION
To receive events, you must use
.B mlx_loop
(). This function never returns, unless
.B mlx_loop_exit
is called. It is an
infinite loop that waits for an event, and then calls a user-defined
function associated with this event. A single parameter is needed,
the connection identifier
.I mlx_ptr
(see the
.B mlx manual).
You can assign different functions to the three following events:
.br
- A key is released
.br
- The mouse button is pressed
.br
- A part of the window should be re-drawn
(this is called an "expose" event, and it is your program's job to handle it in the
Unix/Linux X11 environment, but at the opposite it never happens on Unix/Linux Wayland-Vulkan nor on MacOS).
.br
Each window can define a different function for the same event.
The three functions
.B mlx_key_hook
(),
.B mlx_mouse_hook
() and
.B mlx_expose_hook
() work exactly the same way.
.I funct_ptr
is a pointer to the function you want to be called
when an event occurs. This assignment is specific to the window defined by the
.I win_ptr
identifier. The
.I param
address will be passed back to your function every time it is called, and should be
used to store the parameters it might need.
The syntax for the
.B mlx_loop_hook
() function is similar to the previous ones, but the given function will be
called when no event occurs, and is not bound to a specific window.
When it catches an event, the MiniLibX calls the corresponding function
with fixed parameters:
.nf
expose_hook(void *param);
key_hook(unsigned int keycode, void *param);
mouse_hook(unsigned int button, unsigned int x, unsigned int y, void *param);
loop_hook(void *param);
.fi
These function names are arbitrary. They here are used to distinguish
parameters according to the event. These functions are NOT part of the
MiniLibX.
.I param
is the address specified in the mlx_*_hook calls. This address is never
used nor modified by the MiniLibX. On key and mouse events, additional
information is passed:
.I keycode
tells you which key is pressed (just try to find out :) ),
(
.I x
,
.I y
) are the coordinates of the mouse click in the window, and
.I button
tells you which mouse button was pressed.
.SH GOING FURTHER WITH EVENTS
The MiniLibX provides a much generic access to other available events. The
.I mlx.h
include define
.B mlx_hook()
in the same manner mlx_*_hook functions work. The event and mask values
will be taken from the historical X11 include file "X.h". Some Wayland and MacOS events are mapped
to these values when it makes sense, and the mask may not be used in some configurations.
See source code of the MiniLibX to find out how it will
call your own function for a specific event.

.SH DESCRIPTION
.B mlx_new_image
() creates a new image in memory. It returns a
.I void *
identifier needed to manipulate this image later. It only needs
the size of the image to be created, using the
.I width
and
.I height
parameters, and the
.I mlx_ptr
connection identifier (see the
.B mlx
manual).
The user can draw inside the image (see below), and
can dump the image inside a specified window at any time to
display it on the screen. This is done using
.B mlx_put_image_to_window
(). Three identifiers are needed here, for the connection to the
display, the window to use, and the image (respectively
.I mlx_ptr
,
.I win_ptr
and
.I img_ptr
). The (
.I x
,
.I y
) coordinates define where the image should be placed in the window.
.B mlx_get_data_addr
() returns information about the created image, allowing a user
to modify it later. The
.I img_ptr
parameter specifies the image to use. The three next parameters should
be the addresses of three different valid unsigned integers.
.I bits_per_pixel
will be filled with the number of bits needed to represent a pixel colour
(also called the depth of the image).
.I size_line
is the number of bytes used to store one line of the image in memory.
This information is needed to move from one line to another in the image.
.I format
tells you how each pixel colour in the image is structured. Currently only 2 values are defined:
.P
0 means format B8G8R8A8
.P
1 means format A8R8G8B8
.B mlx_get_data_addr
returns an
.I unsigned char *
address that represents the beginning of the memory area where the image
is stored. From this address, the first
.I bits_per_pixel
bits represent the colour of the first pixel in the first line of
the image. The second group of
.I bits_per_pixel
bits represent the second pixel of the first line, and so on.
Add
.I size_line
to the address to get the beginning of the second line. You can reach any
pixels of the image that way.
.B mlx_destroy_image
destroys the given image (
.I img_ptr
).
.SH STORING COLOURS INSIDE IMAGES
Depending on the graphic system, the number of bits used to store a pixel colour
used to be different from one hardware to another. Today, the way the user usually
represents a colour, in the ARGB mode, almost always matches the hardware capabilities
on modern computers.
Keep in mind that packing the 4-byte ARGB into an unsigned int depends on the local
computer's endian. Adjust your code accordingly.
.SH XPM AND PNG IMAGES
The
.B mlx_xpm_to_image
() ,
.B mlx_xpm_file_to_image
() and
.B mlx_png_file_to_image
() functions will create a new image the same way.
They will fill it using the specified
.I xpm_data
or
.I filename
, depending on which function is used.
Note that MiniLibX does not use the standard
Xpm and png libraries to deal with xpm and png images. You may not be able to
read all types of xpm and png images. It however handles transparency.
.SH RETURN VALUES
The four functions that create images,
.B mlx_new_image()
,
.B mlx_xpm_to_image()
,
.B mlx_xpm_file_to_image()
and
.B mlx_png_file_to_image()
, will return NULL if an error occurs. Otherwise they return a non-null pointer
as an image identifier.

.SH DESCRIPTION
The
.B mlx_new_window
() function creates a new window on the screen, using the
.I width
and
.I height
parameters to determine its size, and
.I title
as the text that should be displayed in the window's title bar.
The
.I mlx_ptr
parameter is the connection identifier returned by
.B mlx_init
() (see the
.B mlx
man page).
.B mlx_new_window
() returns a
.I void *
window identifier that can be used by other MiniLibX calls.
Note that the MiniLibX
can handle an arbitrary number of separate windows.
.B mlx_clear_window
() and
.B mlx_destroy_window
() respectively clear (in black) and destroy the given window. They both have
the same parameters:
.I mlx_ptr
is the screen connection identifier, and
.I win_ptr
is a window identifier.
.SH RETURN VALUES
If
.B mlx_new_window()
fails to create a new window (whatever the reason), it will return NULL,
otherwise a non-null pointer is returned as a window identifier.
.B mlx_clear_window
and
.B mlx_destroy_window
return nothing.

.B mlx_pixel_put

.nf
.I int
.fi
.B mlx_string_put
(
.I void *mlx_ptr, void *win_ptr, unsigned int x, unsigned int y, unsigned int color, char *string
);
.SH DESCRIPTION
The
.B mlx_pixel_put
() function draws a defined pixel in the window
.I win_ptr
using the (
.I x
,
.I y
) coordinates, and the specified
.I color
\&. The origin (0,0) is the upper left corner of the window, the x and y axis
respectively pointing right and down. The connection
identifier,
.I mlx_ptr
, is needed (see the
.B mlx
man page).
Parameters for
.B mlx_string_put
() have the same meaning. Instead of a simple pixel, the specified
.I string
will be displayed at (
.I x
,
.I y
).
Both functions will discard any display outside the window. This makes
.B mlx_pixel_put
slow. Consider using images instead.
.SH COLOUR MANAGEMENT
The
.I color
parameter has an unsigned integer type. The displayed colour needs to be encoded
in this integer, following a defined scheme. All displayable colours
can be split in 3 basic colours: red, green and blue. Three associated
values, in the 0-255 range, represent how much of each colour is mixed up
to create the original colour. The fourth byte represent transparency,
where 0 is fully transparent and 255 opaque. Theses four values must be set inside the
unsigned integer to display the right colour. The bytes of
this integer are filled as shown in the picture below:
.nf
| B | G | R | A | colour integer
+---+---+---+---+
.fi
While filling the integer, make sure you avoid endian problems. Example:
the "blue" byte will be the least significant byte inside the integer on a
little endian machine.
