## M_pixel - low level pixel graphics library

## DESCRIPTION

This is a library that creates pixel images with a vector-oriented

graphics library that emulates a subset of the M_draw vector graphics

library. It is supplemented with additional modules that read and write

GIF files, including animated GIFs.

The user may supplement the routines by directly manipulating the pixel

map as well.

## BUILDING THE MODULES

     git clone https://github.com/urbanjost/M_pixel.git

     cd M_pixel/src

     # change Makefile if not using one of the listed compilers

     

     # for gfortran

     make clean

     make F90=gfortran gfortran

     

     # for ifort

     make clean

     make F90=ifort ifort

     # for nvfortran

     make clean

     make F90=nvfortran nvfortran

This will compile the Fortran and basic example programs that exercise

the routines.

## DOCUMENTATION   ![docs](docs/images/docs.gif)

### USER 

   - an [index](https://urbanjost.github.io/M_pixel/man3.html) to

     the individual man-pages in HTML form

   - A single page that uses javascript to combine all the HTML

     descriptions of the man-pages is at 

     [BOOK_M_pixel](https://urbanjost.github.io/M_pixel/BOOK_M_pixel.html).

   - [CHANGELOG](docs/CHANGELOG.md) provides a history of significant changes

### DEVELOPER 

   - [ford(1) output](https://urbanjost.github.io/M_pixel/fpm-ford/index.html).

   - [github action status](docs/STATUS.md) 

## ADDITIONAL DIRECTORY DESCRIPTIONS

There are 

   - man-pages in [docs/manpages.tgz](docs/manpages.tgz) and [docs/manpages.zip](docs/manpages.zip)

   - demo programs in the [example/](example/) directory

   - applications in the app/ directory

## UNIT TESTS

There are no automated unit tests per-se. Running the example programs

and demo programs ensures the library is functioning.

## FUTURE

There are a collection of higher-level routines that need added, as well

as more font support, and antialiasing and basic pixel operations (the

library currently primarily provides two-dimensional vector-like commands).

An example program using this low-level library to generate higher-level

graphics:
