[![Build](https://github.com/42Paris/minilibx-linux/actions/workflows/ci.yml/badge.svg)](https://github.com/42Paris/minilibx-linux/actions/workflows/ci.yml)
This is the MinilibX, a simple X-Window (X11R6) programming API
in C, designed for students, suitable for X-beginners.
Contents
- source code in C to create the mlx library
- man pages (in man/ directory)
- a test program (in test/ directory) is built
with the library
- a public include file mlx.h
- a tiny configure script to generate an appropriate Makefile.gen
Requirements for Linux
- MinilibX only support TrueColor visual type (8,15,16,24 or 32 bits depth)
- gcc
- make
- X11 include files (package xorg)
- XShm extension must be present (package libxext-dev)
- Utility functions from BSD systems - development files (package libbsd-dev)
- **e.g. _sudo apt-get install gcc make xorg libxext-dev libbsd-dev_ (Debian/Ubuntu)**
Requirements for MacOS
- [Xquartz](https://www.xquartz.org/)
```bash
➜ ~ Brew install Xquartz
➜ ~ reboot
➜ ~ xeyes # run an hello world X11 app
```
MlX Color Opacity / Transparency / Alpha (32 bits depth)
- 0xFF (fully transparent) or 0x00 (fully opaque)
Compile MinilibX
- run ./configure or make
both will make a few tests, create Makefile.gen
and then automatically run make on this generated Makefile.gen .
libmlx.a and libmlx_$(HOSTTYPE).a are created.
test/mlx-test binary is also created.
Install MinilibX
- no installation script is provided. You may want to install
- libmlx.a and/or libmlx_$(HOSTTYPE).a in /usr/X11/lib or /usr/local/lib
- mlx.h in /usr/X11/include or /usr/local/include
- man/man3/mlx*.1 in /usr/X11/man/man3 or /usr/local/man/man3

.TH MiniLibX 3 "September 19, 2002"
.SH NAME
MiniLibX - Simple X-Window Interface Library for students
.SH SYNOPSYS
#include <mlx.h>
.nf
.I void *
.fi
.B mlx_init
();
.SH DESCRIPTION
MiniLibX is an easy way to create graphical software,
without any X-Window programming knowledge. It provides
simple window creation, a drawing tool, image and basic events
management.
.SH 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 refered 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).
.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 display.
Once this connection is established, you'll be able to
use other MiniLibX functions to send the X-Server messages,
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.
.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 window
.TP 20
.B mlx_new_image
: manipulate images
.TP 20
.B mlx_loop
: handle keyboard or mouse events
.SH LINKING MiniLibX
To use MiniLibX functions, you'll need to link
your software with several libraries, including the MiniLibX library itself.
To do this, simply add the following arguments at linking time:
.B -lmlx -lXext -lX11
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 X server, it will return NULL, otherwise
a non-null pointer is returned as a connection identifier.

.SH X-WINDOW EVENTS
The X-Window system is bi-directionnal. 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. 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 pressed
.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).
.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
adress will be passed to the function everytime it is called, and should be
used to store the parameters it might need.
The syntax for the
.B mlx_loop_hook
() function is identical to the previous ones, but the given function will be
called when no event occurs.
When it catches an event, the MiniLibX calls the corresponding function
with fixed parameters:
.nf
expose_hook(void *param);
key_hook(int keycode,void *param);
mouse_hook(int button,int x,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 (look for the X11 include file "keysymdef.h"),
(
.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 all X-Window 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 X11 include file "X.h".
See source code of mlx_int_param_event.c to find out how the MiniLibX 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 integers.
.I bits_per_pixel
will be filled with the number of bits needed to represent a pixel color
(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 endian
tells you wether the pixel color in the image needs to be stored in
little endian (
.I endian
== 0), or big endian (
.I endian
== 1).
.B mlx_get_data_addr
returns a
.I char *
address that represents the begining of the memory area where the image
is stored. From this adress, the first
.I bits_per_pixel
bits represent the color 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 adress to get the begining 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 COLOR INSIDE IMAGES
Depending on the display, the number of bits used to store a pixel color
can change. The user usually represents a color in RGB mode, using
one byte for each component (see
.B mlx_pixel_put
manual). This must be translated to fit the
.I bits_per_pixel
requirement of the image, and make the color understandable to the X-Server.
That is the purpose of the
.B mlx_get_color_value
() function. It takes a standard RGB
.I color
parameter, and returns an
.I unsigned int
value.
The
.I bits_per_pixel
least significant bits of this value can be stored in the image.
Keep in mind that the least significant bits position depends on the local
computer's endian. If the endian of the image (in fact the endian of
the X-Server's computer) differs from the local endian, then the value should
be transformed before being used.
.SH XPM IMAGES
The
.B mlx_xpm_to_image
() and
.B mlx_xpm_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 library to deal with xpm images. You may not be able to
read all types of xpm images. It however handles transparency.
.SH RETURN VALUES
The three functions that create images,
.B mlx_new_image()
,
.B mlx_xpm_to_image()
and
.B mlx_xpm_file_to_image()
, will return NULL if an error occurs. Otherwise they return a non-null pointer
as an image identifier.

.SH DESCRIPTION
The

() 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

.I string
will be displayed at (
.I x
,
.I y
).
In both functions, it is impossible to display anything outside the
specified window, nor display in another window in front of the selected one.
.SH COLOR MANAGEMENT
The
.I color
parameter has an integer type. The displayed color needs to be encoded
in this integer, following a defined scheme. All displayable colors
can be split in 3 basic colors: red, green and blue. Three associated
values, in the 0-255 range, represent how much of each color is mixed up
to create the original color. Theses three values must be set inside the
integer to display the right color. The three least significant bytes of
this integer are filled as shown in the picture below:

c s s s s
r c c c c.
Color Integer
Interpretation \[*a] R G B
Bit numbers 31..24 23..16 15..8 7..0

While filling the integer, make sure you avoid endian problems. Remember
that the "blue" byte should always be the least significant one.

.SH NAME
MiniLibX - Simple X-Window Interface Library for students
.SH SYNOPSYS
#include <mlx.h>
.nf
.I void *
.fi
.B mlx_init
();
.SH DESCRIPTION
MiniLibX is an easy way to create graphical software,
without any X-Window programming knowledge. It provides
simple window creation, a drawing tool, image and basic events
management.
.SH 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 refered 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).
.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 display.
Once this connection is established, you'll be able to
use other MiniLibX functions to send the X-Server messages,
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.
.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 window
.TP 20
.B mlx_new_image
: manipulate images
.TP 20
.B mlx_loop
: handle keyboard or mouse events
.SH LINKING MiniLibX
To use MiniLibX functions, you'll need to link
your software with several libraries, including the MiniLibX library itself.
To do this, simply add the following arguments at linking time:
.B -lmlx -lXext -lX11
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 X server, it will return NULL, otherwise
a non-null pointer is returned as a connection identifier.

.SH X-WINDOW EVENTS
The X-Window system is bi-directionnal. 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. 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 pressed
.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).
.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
adress will be passed to the function everytime it is called, and should be
used to store the parameters it might need.
The syntax for the
.B mlx_loop_hook
() function is identical to the previous ones, but the given function will be
called when no event occurs.
When it catches an event, the MiniLibX calls the corresponding function
with fixed parameters:
.nf
expose_hook(void *param);
key_hook(int keycode,void *param);
mouse_hook(int button,int x,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 (look for the X11 include file "keysymdef.h"),
(
.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 all X-Window 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 X11 include file "X.h".
See source code of mlx_int_param_event.c to find out how the MiniLibX 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 integers.
.I bits_per_pixel
will be filled with the number of bits needed to represent a pixel color
(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 endian
tells you wether the pixel color in the image needs to be stored in
little endian (
.I endian
== 0), or big endian (
.I endian
== 1).
.B mlx_get_data_addr
returns a
.I char *
address that represents the begining of the memory area where the image
is stored. From this adress, the first
.I bits_per_pixel
bits represent the color 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 adress to get the begining 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 COLOR INSIDE IMAGES
Depending on the display, the number of bits used to store a pixel color
can change. The user usually represents a color in RGB mode, using
one byte for each component (see
.B mlx_pixel_put
manual). This must be translated to fit the
.I bits_per_pixel
requirement of the image, and make the color understandable to the X-Server.
That is the purpose of the
.B mlx_get_color_value
() function. It takes a standard RGB
.I color
parameter, and returns an
.I unsigned int
value.
The
.I bits_per_pixel
least significant bits of this value can be stored in the image.
Keep in mind that the least significant bits position depends on the local
computer's endian. If the endian of the image (in fact the endian of
the X-Server's computer) differs from the local endian, then the value should
be transformed before being used.
.SH XPM IMAGES
The
.B mlx_xpm_to_image
() and
.B mlx_xpm_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 library to deal with xpm images. You may not be able to
read all types of xpm images. It however handles transparency.
.SH RETURN VALUES
The three functions that create images,
.B mlx_new_image()
,
.B mlx_xpm_to_image()
and
.B mlx_xpm_file_to_image()
, will return NULL if an error occurs. Otherwise they return a non-null pointer
as an image identifier.
