EZFB 11.00 3/21/2016
This is a new release based on the popularity of the Raspberry Pi!
The previous version of this code set did not work well because of
something I never thought of... The address of the pointer that is the
base of the video RAM can change after certain ioctl function calls!
So I fixed that. The reason I went to version 11 is because it's 11.
The LaserBoy code is no longer included as it has taken on a life of its own
EZFB 10.00 3/21/2008
This is an entirely new release of ezfb. It is so different than
the previous version, of more that 3 years ago,
individual changes are too many to list.
The entire core of the frame buffer has been optimized with pre-calculated
pointers to pixel rows, eliminating a lot of redundant math
and pointers to functions, set at initialization, eliminating
redundant switch statements. In other words it's a lot faster!
New features have been added to enhance and accelerate animation
in the frame buffer.
A fully functional version of
is included in this release.
EZFB 9.05 1/21/2005
All of the work for this release went into
ilda.cpp and ilda.hpp
that provide the ILDA functionality for
Fixed even more bugs. Redesigned the inner most class,
to contain STL vectors of class
that replace the C-style pointers to shorts or chars,
(x, y, z, k, c, r, g, b)
used to store the arrays of points in a frame or colors in a palette.
This is in preparation for points optimization routines
that will come in the future. Added the function
to reduce the amount of data stored on disk by eliminating
all but one blank point between any two shapes in a frame.
function in the class
so that it saves
one frame with a
of zero points at the end of the file,
in accordance with the ILDA file format standard.
EZFB 9.04 1/18/2005
Fixed lots of bugs. Cleaned up the entire project
namespace by changing the names of many functions, macros,
variables and even data types. Split bmp_clone_ezfb
so that it does not corrupt palette display.
Changed the name of the ild2fb project to
Made extensive changes to laserboy. Added global palette selection.
Fixed recolor effects. And so much more!
EZFB 9.03 1/1/2005
Fixed a lot of bugs. Added two new functions;
set_ezfb_xy_virtual and set_ezfb_xy_offsets,
making it possible to set up the video memory area to be
larger than the visible screen and to move the visible screen
area around in the video memory. This also marks the first
release of ezfb that includes a driver for The International
Laser Display Association's ILDA file format and an application
for generating, displaying, transforming and saving ILDA files.
This release of the project has been verified to work with
Fedora Core 3 and Linux kernel 2.6.9!
EZFB 9.02 8/21/2004
Fixed a few more bugs. Noticed that the Make file was setup to use g++.
Fixed it to be gcc (the standard C compiler) and made sure it still compiled!
Now all of the demo code compiles clean with either gcc or g++.
EZFB 9.01 2/5/2004
Fixed a few bugs.
EZFB 9.00 1/30/2004
Fixed all of the code to compile C/C++ cleanly with gcc and g++
in gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5).
Added some new color palettes. Added to the bitmapped memory
object routines to enhance memory to screen transfers for smoother,
EZFB 8.00 11/02/2003
Total rework of the whole project. Added signal trapping
and the ability to independantly control many video cards
from separate processes or within the same process.
EZFB 6.02 08/09/2002
Improved color reduction. Added functions rgb_hue(fb, index),
rgb_tint(fb, index, tint), rgb_shade(fb, index, shade),
set_fb_background(fb, rgb). Added "save screen" to ./jl
computer art generating demo. Fixed palette cycling a few other
EZFB 6.01 07/17/2002
Got 4 bit color reduction working! Can now display all
types of bitmap files in 4 bit color. Also added 1 bit per pixel
bitmap display for all frame buffer color depths. Renamed
set_fb_cmap_332(fb) to set_fb_cmap_reduction(fb).
EZFB 6.00 07/13/2002
First public release.
