Plain English Copyright Notice
This file is not intended to be the actual License. The reason this file
exists is that we here are programmers and engineers. We aren't lawyers. We
provide licenses that we THINK say the right things, but we have our own
intentions at heart. This is a plain-english explanation of what those
intentions are, and if you follow them you will be within the "spirit" of
the license.
The intent is for us to enjoy writing software that is useful to us (the
AUTHORS) and allow others to use it freely and also benefit from the work we
put into making it. We don't want to restrict others using it. They should
not *HAVE* to make the source code of the applications they write that
simply link to these libraries (be that statically or dynamically), or for
them to be limited as to what license they choose to use (be it open, closed
or anything else). But we would like to know you are using these libraries.
We simply would like to know that it has been useful to someone. This is why
we ask for acknowledgement of some sort.
You can do what you want with the source of this software - it doesn't
matter. We still have it here for ourselves and it is open and free to use
and download and play with. It can't be taken away. We don't really mind what
you do with the source to your software. We would simply like to know that
you are using it - especially if it makes it to a commerical product. If you
simply e-mail all the AUTHORS (see COPYING and AUTHORS files) telling us, and
then make sure you include a paragraph or page in the manual for the product
with the copyright notice and state that you used this software, we will be
very happy. If you want to contribute back modifications and fixes you may have
made we will welcome those too with open arms (generally). If you want help
with changes needed, ports needed or features to be added, arrangements can
be easily made with some dialogue.

####################
# Evas 1.0.0 pre-4 #
####################
This is a !!!!**** PRE RELEASE ****!!!!.
This does NOT mean this is a 1.0.0. It is not complete. It has a 1.0.0
version to make sure it does not conflict with previous evas versions
(0.6.0). 1.0.0 is there because this codebase is PLANNED for 1.0.0. The API
is now stable and I'm happy with it. Until a final 1.0.0, all releases will
have a pre-<number> release. Don't be fooled though. This code should be
stable and fast, but it just may be missing features (like a fully working
OpenGL engine, or documentation).
When this no longer has a pre-<something> as its version THEN it is ready.
--------------------------------------------------------------------------
Requires:
freetype 2.0.x (I want to make this optional)
Optional:
X11R6
DirectFB
OpenGL (underway at the moment)
Linux
libpng
libjpeg
libeet
libedb
--------------------------------------------------------------------------
Evas as of 1.0.0 has a new (and incompatible) API. Why? It's much cleaner
and more compact. Designed for portable access to different display systems.
It is also much more optimised internally, uses much less ram than previous
Evas libraries, and is tiny. Evas when compiled for the Ipaq is a grand
total of 191Kb (thats all of Evas minus libjpeg, libpng, libz (required for
libpng), and minus freetype (required for font rendering)). I have plans that
may involve having an alternative font engine other than freetype to minimise
requirements, and having a native (optional) image loader for an image
format that may end up being custom to evas, but will minimise code &
requirements especially for embedded use.
Evas uses very little RAM too (try profiling it in memprof if you want to
know) most of the ram allocated, if you look, is for freetype itself,
image pixel data, and font glyph data. You can't really avoid this, though
evas tries to share this data as much as possible and not duplicate where it
can. Feel free to point me at sensible memory optimisations etc. though :) I
want this baby to be lean, mean tiny, fast and do everything from your
massive multi-cpu desktop with gobs of ram and disk to a tiny watch.
Evas also supports full UTF-8 for text object strings, thus allowing for
full internationalised text strins (if your font gives you all the
characters). I've tested with quite a few fonts and it works quite well.
Though this requires a unicode compatible font with unicode charmap support
(cyberbit is quite good actually as a font). For now Evas draws the fonts
only from left to right, so arabic, hebrew etc. won't display quite right,
direction-wise, but the charcters do.

if you want to know what options to enable
./confiugre --help
Notes:
you must enable one and ONLY one scaler. ie: --enable-scale-smooth
you only need scalers and converters and have to provide cpu info if using
the fb or software x11 engines right now.
you must enable some level of cpu optimisations (at least C, if not mmx and
sse) ie: --enable-cpu-c --enable-cpu-mmx --enable-cpu-sse
you will find much improved performance on pentium and pentium2, and amd
cpu's if you use --enable-cpu-p2-only
if you have a pentium3 or 4 you may see more speed with
--enable-cpu-p3-only (do not use in combination with --enable-cpu-p2-only)
if you use the fb or software_x11 engines if you don't build in a converter
for at least the depth you run, then display won't work. they are all
optional for the purpose of leaning evas down for embedded devices to only
inlcude the code you need. if you have the disk and ram space then enable
all the converters
the small dither mask is faster on the ipaq, but is not as good looking. on
desktop machines it makes no speed difference so only use
--enable-small-dither-mask if you are compiling for the ipaq
you need at least 1 image loader if you want to load images.
--------------------------------------------------------------------------
notes on features:
SCALING:
--enable-scale-sample
this enables the sampling scaler code. this is the fastest image scaling
code, but also the lowest quality. when scaling up pixels will become blocky
and when scaling down you will see shimmering/aliasing artifacts. this is a
speed vs. quality tradeoff
--enable-scale-trilinear
this enables tilinear scaling. it uses a similar algorithm to what 3d cards
do - the quality is good and speed is slower than sampled scaling, but looks
a bit better. uses extra ram (up to 33% more) for image data for mipmaps
(they are built on-demand), but is a nice compromise
--enable-scale-smooth
this is the nicest looking scaler that is not that much slower than
tri-linear, but it looks really good. it also uses mipmaps and is optimised
heavily. it is recommended to always use this unless you are really
struggling for speed and are qilling to forego the quality
DITHERING:
--enable-small-dither-mask
this uses a 4x4 dither mask instead of 128x128. on desktop boxes these days
(pentium, pentium2, amd etc.) the speed difference is not really measurable,
but the quality of the 128x128 dither mask is quite a lot better. patterns
of dithering are much less noticable, so it is recommended to not enable
this unless you are struggling for speed. the compaq ipaq for example shows
a slowdown with this large a dither mask so enabling a small dither mask is
recommended unless you really want to forego the speed.
ENGINES:
--enable-software-x11
this enables the software x11 rendering engine that renders to X drawable
targets using highly optimised software routines. there is no hardware
assist here. this engine requires X11 to be installed to build (and run).
This si a godo generic engine that is fast and can run in X for good
development and debugging purposes.
--enable-fb
this is the software framebuffer drivign engine. this uses the linxu
framebuffer device (/dev/fb<x>) and will currently just inherit the current
framebuffer settings on the fb device and use them to run in. this engine is
almost fully functional except for the fb management itself. i'd be quite
happy for people to help out with fixing up the fb init & management code to
properly set up a vt and release it etc. this engine is specifically geared
towards peoel writing minimalist display systems for embedded devices such
as the ipaq, zaurus, etc. it also scales up to high-res desktop systems as
well and performs outstandingly. i have measured up to 67% speedup over X11
using the fb driver insetad of X11.
--enable-direcfb
this is the direct fb engine that uses direcftb (http://www.directfb.org) on
linux to access the framebuffer with (or maybe without) acceleration. for
people making set-top boxes or just wanting an alternative to X this is
really good. it may also be useful for embedded devices supported by
directfb that offer acceleration (otherwise the fb driver will likely be
faster).
CPU:
--enable-cpu-p2-only
this tricks the cpu detecting code to avoid detection routines and assume a
pentium, pentium2, amd etc. cpu and use mmx routines (it's a bit misnamed -
but hey). this is suggested if your target is a pentium and up system.
--enable-cpu-p3-only
this tricks the cpu detection code into thinking you have a pentium3 or up
cpu (not - this is NOt for amd processors). it is suggested for p3 or 4
targets for more speedups again. if you use this option do NOt use the
--enable-cpu-p2-only option.
--enable-cpu-c
this enabled the c code. you can actually build the code withotu the c
fallback code and only have the mmx routines for example. it is suggested to
always use this regardless uness you have some definite size issues with the
code.
--enable-cpu-mmx
this enables the mmx optimised routines. this works for penitum, pentium2,
pentium3, pentium4, athlon and duron processors. it can get quite
considerable speedups, souse it if you can. ppc owners just have to live with
the c fallback functions unfortunately as no one has provided any ALTIVEC asm
routines yet. :) arm owners will also have to rely on the c fallback
routines as i haven't managed to come up with any arm assembly that actually
can beat the c code (when compiled whht all optimisations) in speed.
--enable-cpu-sse
this enables sse optimisations availbale in he pentium3 and 4 cpus (not
athlon and duron or pentium 2 or pentium cpu's). ppc owners just have to
live with the c fallback functions unfortunately as no one has provided any
ALTIVEC asm routines yet. :) arm owners will also have to rely on the c
fallback routines as i haven't managed to come up with any arm assembly that
actually can beat the c code (when compiled whht all optimisations) in speed.
IMAGE LOADERS:
--enable-image-loader-png
this enables the loader code that loads png files using libpng. there may be
call for embedded devices later that have custom written small image
loaders that use sless disk space than libpng to load custom format images.
for now this is the only loader so you may as well include it.
--enable-image-loader-jpeg
this enables the loader code that loads jpeg files using libjpeg.
CONVERTERS:
--enable-convert-16-rgb-565
the most common converter you'll want for 16bpp. this means 5 bits for red,
6 bits for green and 5 bits for blue are used.
--enable-convert-16-rgb-555
this is a converter for what many peoel knwo as "15 bit" color. you might
want to enable this for X output as it used to be common to find many cards
that do this.
--enable-convert-16-rgb-444
this converter outputs to 12bit packed (int 16 bit WORDS).
--enable-convert-16-rgb-ipq
this converter was written specifically for the ipaq (and may apply to
similarly configured devices) because it lies about its screen depth. it
days its 16bit 565 (that means 5 upper bits of the WORD are red, the next 6
bits are for green abd the next 5 for blue) but in fact only the upper 4
bits of each color component (red green and blue) are significant and work,
so effectively the display is 12 bits of color, not 16, but padded out to
fill 16bits, with unused bits in the color masks. X on the ipaq advertises
it as a full 16bpp 565 display (i can't remember what the linxu framebuffer
advertised it as) and so many lumsp fo code can be fooled into rendering
data badly because they think the output will look as the expect. thsi
renderer assuems the upper 4 bits fo each color primitie only are
significant and renders accordingly. this produces nice quality images on
the ipaq and even still works in 16bpp 565 on your pc. it is highly
recommended to use thsi renderer if your target is an ipaq or your device
dislpays similar qualities of the ipaq for display purposes.
--enable-convert-16-rgb-rot-0
this enables the 16bpp converters to run with 0 degrees rotation - this is
normal disp;ay and you shoudl really include this (though it is optional if you
only ever want to do portrait mode - perhaps like on an ipaq embedded device)
--enable-convert-16-rgb-rot-270
this enables the portrait mode (270 degree rotation) converteres for 16bpp.
this is the standard display mode for things like pocketpc on the ipaq and
the zaurus etc. thsi si a optimised part of the rendering pipeline to allow
portrait display with a much lower overhead than doing it through X.

@section intro What is Evas?
Evas is a clean display canvas API for several display systems that can draw
anti-aliased text, smooth super and sub-sampled scaled images, alpha-blend
objects much and more.
It abstracts any need to know much about what the characteristics of your
display system are or what graphics calls are used to draw them and how. It
deals on an object level where all you do is create and manipulate objects
in a canvas, set their properties, and the rest is done for you.
Evas optimises the rendering pipeline to minimise effort in redrawing changes
made to the canvas and so takes this work out of the programmers hand,
saving a lot of time and energy.
It's small and lean, designed to work on embedded systems all the way to
large and powerful multi-cpu workstations. It can be compiled to only have
the features you need for your target platform if you so wish, thus keeping
it small and lean. It has several display back-ends, letting it display on
several display systems, making it portable for cross-device and
cross-platform development.
@section work How does Evas work?
Evas is a canvas display library. This is markedly different from most
display and windowing systemas as a Canvas is structural and is also a state
engine, wheras most display and windowing systems are immediate mode display
targets. Evas handles the logic between a structural display via its' state
engine, and controls the target windowing system in order to produce
rendered results of the current canvases state on the display.
Immediate mode display systems retain very little, or no state. A program
will execute a series of commands:
@verbatim
bitmap_handle = create_new_bitmap();
draw_line(0, 0, 100, 200);
draw_rectangle(10, 30, 50, 500);
draw_bitmap(10, 30, bitmap_handle);
etc.
@endverbatim
The series of commands is executed by the windowing system and the results
are displays on the screen (normally). Once the commands are executed the
display system has little or no idea of how to reproduce this image again,
and so has to be instructed by the application how to redraw sections of the
screen whenever needed. Each sucessive command will be executed as
instructed by the application and either emulated by software or sent to the
graphics hardware on the device to be performed.
The advantage of such a system is that it is simple, and gives a program
tight control over how something looks and is drawn. Given the increasing
comlpexity of displays and demands by users to have better looking
interfaces, more and more work is needing to be done at this level by the
internals of widget sets, custom display widgets and other programs. This
means more and more logic and display rendering code needs to be written
time and time again, each time the application needs to figure out how to
minimise redraws so that display is fast and interactive, and keep track of
redraw logic. The power comes at a high-price, lots of extra code and work.
Programmers not very familiar with graphics programming will often make
mistakes at this level and produce code that is sub optimal. Those familiar
with this kind of programming will simply get bored by writign the same code
again and again.
Evas is a structural system in which the programmer creates and manages
display objects and their properties, and as a result of this higher level
state management, the canvas is able to redraw the set of objects when
needed to represent the current state of the canvas.
For example:
@verbatim
bitmap_handle = create_bitmap();
move(bitmap_handle, 10, 30);
show(bitmap_handle);
rectangle_handle = create_rectangle();
move(rectangle_handle, 10, 30);
resize(rectangle_handle, 50, 500);
show(rectangle_handle);
line_handle = create_line();
set_line_coords(line_handle, 0, 0, 100, 200);
show(line_handle);
etc.
@endverbatim
This may look longer, but when the display needs to be refreshed or updated,
the programmer only moves, resizes, shows, hides etc. the objects that they
need to change. The programmer simply thinks at the object logic level, and
the canvas software does the rest of the work for them, figuring out what
actually changed in the canvas since it was lastdrawn, how to most
efficiently redraw he canvas and its contents to reflect the current state,
and then it can go off and do the actual drawing of the canvas.
This lets the programmer think in a more natural way when dealing with a
display, and saves time and effort of woring out how to load and display
images, render given the current display system etc. Since Evas also is
portable across different display systems, this also gives the programmer
the ability to have their code ported and display on different dislpay
systems with very little work.
Evas can be seen as a display system that stands somewhere between a widget
set and an immediate mode display system. It retains basic dislpay logic,
but does very little high-level logic such as scrollbars, sliders, push
buttons etc.
@section compiling How to compile using Evas?
Evas is a library your application links to. The proceedure for this is very
simple. You simply have to compile your application with the appropriate
compiler flags that the @p evas-config script outputs. For example:
Compiling C or C++ files into object files:
@verbatim
gcc -c main.c -o main.o `evas-config --cflags`
@endverbatim
Linking object files into a binary executable:
@verbatim
gcc main.o -o my_application `evas-config --libs`
@endverbatim
You simply have to make sure that evas-config is in your shell's PATH (see
the manual page for your appropriate shell), or simply use the full path to
where @p evas-config was installed. It's that simple to link and use Evas
once you have written your code to use it.
Since the program is linked to Evas, it is now able to use any advertised
API calls to display graphics in a canvas managed by Evas, as well as use
the API calls provided to manage data as well.
You should make sure you add any extra compile and link flags to your
compile commands that your application may need as well. The above example
is only guaranteed to make Evas add it's own requirements.
