MGRX is a 2D graphics library derived from the GRX library. GRX was originaly written by Csaba Biegl for DJ Delorie's DOS port of the GCC compiler.
MGRX supports five platforms: DOS (DJGPPv2), Linux console, Linux X11, Linux Wayland and Win32 (TDM-GCC). On DOS it supports VGA and VESA compliant cards. On Linux console it comes with framebuffer and KMS/DRM videodrivers. On X11, Wayland and Win32 it runs in a window.
For the Linux console, Linux X11 and the Linux Wayland versions three architectures are supported: i386 (32bit), x86_64 (64bit) and ARM (32bit, tested in a Raspberry Pi 4 using Raspbian).
MGRX comes with GrGUI, a mini Graphics User Interface specifically designed for MGRX.
The Linux X11, Linux Wayland and Win32 videodrivers support user window resize.
The Wayland videodriver was new in version 1.5.0, it must be considered in beta stage, only the i386 and x86_64 architectures are tested at the moment.
MGRX is a fork of GRX. Because I liked the GRX C API interface, I began to maintain GRX when it was orphaned at the end of 2000. But GRX has not only the C API, it has a Pascal API, a BGI compatibility API, support for Turbo C, Wattcom, MSC and some X11 implementations over mainframes. At the end it was not funny, it was easy to break things I didn't know (and I didn't want to know). So I stopped maintainig GRX at the end of 2003.
After that I developed a fork for my own use, only the C API, no Pascal, no BGI, no Turbo C support, only the 5 platforms I can test. It has a new (and better I think) input API and some (limited) international support. I have released it for fun, maybe it can be useful for someone.
Latest versions of OS, compiler, and key software tested:
Global dependencies, for all platforms, are libjpeg (for reading and writing JPEG files) and libpng and zlib (for reading and writing PNG files). But if you don't have those libraries in your platform you can disable JPEG and PNG support editing the "makedefs.grx" file before compilation (See the readme file bellow).
Anyway it's easy to install the binary libraries at least in Linux and DJGPP. For TDM-GCC (Win32) you have to compile them, it isn't too difficult, or you can download this package with the libraries already compiled by me and install them for TDM-GCC following the simple instructions in the included readme file.
For linux console if the KMS/DRM driver is enabled the libdrm library will be needed, normally it is included in most linux distributions by default, but you will need to install the developper files.
For linux X11 you need libX11, normally installed by default, but you will need to install the developper files.
For linux Wayland you need libwayland-client and libxkbcommon, also normally installed by default, but you also will need to install the developper files.
