PNG and OS4 icons with only one image will automatically get
a darker second image with a simple glowing effect around it.
An alternative 16 color FullPalette.prefs file is available.
A fix for PNG icons without alpha channel for the 68000 CPU.
Description:
~~~~~~~~~~~
The icon.library has been written completely in optimized ASM
code with IconBeFast 2 already built in. It works much faster
now and is also a lot smaller than the original icon.library.
Added direct support for workbench.library version 39 and 40.
Two libraries are included now, for 68000 and 68020+ systems.
And there's a new third version of the library supplied with
the file extension "lined" which uses the older line by line
direct drawing code because sometimes that runs still faster.
The best 68000 setup I could find was a combination with the
workbench.library 45.127 loaded either by LoadResident or by
SetPatch v44. Using one of the original WB-Libs v44+ - v45.127
has many advantages. No icon frames, it consumes less ChipMem,
it's faster and it's the only way to swap images with WB-info.
This library can now display the 32 bit ARGB icons of OS4 on
any AGA screen with the normal 8 bit color mapping of OS 3.5+.
WB:icon->info will convert these icons into the OS 3.5 format!
The old style planar images of the OS4 icons are replaced now
by the smaller internal default images since many were broken.
Added support for displaying Dual-PNG icons on any AGA screen.
Icon snapshot converts your PNG icons into the OS 3.5 format!
On 020+ you will see a requester in case PNG or OS4 TrueColor
icons need to be converted into the OS 3.5 format. It can be
allowed or prevented for a single icon, in drawers or always.
This format has the advantage of getting small files and fast
icon loading, although there's hardly a visible quality loss.
A zlib inflate function is already embedded for uncompressing
the OS4 and PNG images. No need for the external zlib.library.
The inflate routine of the 68000 version was replaced by new
code which has been written by Keir Fraser. It saves >2.5 kB
disk space and consumes 35 kB less memory. Thanks to Kaffer!
A direct drawing mode for all gfx-cards in HiColor quality is
is now available. The PowerIcons patch isn't required anymore
and should be removed now. The direct drawing on Hi/TrueColor
screens is really fast, even faster than normal color mapping.
The 68000 version has no direct drawing support builtin, since
there are no gfx-cards or drivers available. And because FBlit
also won't run on a 68000 CPU, it's impossible to use FastMem.
( The new command NoDelayedImage2 makes it possible to support
the original PowerIcons patch 1.06 again, if someone needs it.
But remember that PI displays and saves only one PNG image! ;)
Other new features are the ghosted deficons (50% transparent)
and the optional outline text for icons on the Workbench v44+.
Furthermore, you can enable shadow text for icons on WB 3.5+.
Generating the shadow text is a lot faster than outline text.
Deficons without a transparent color defined are an exception
to allow Eastern to display its preview pictures still opaque.
If you don't like transparent deficons call IconGhostingOff.
And now a simple hack for all the GhostBusters: If you really
don't like icon ghosting to be enabled by default then take a
HEX-editor, scan the icon.library for $74FF4AAD and change it
into $74004AAD. Also scan for $6B2C and replace it with $602C.
A new tooltype for DefIcons to disable the IconGhosting. You
can now add the tooltype "NoGhost" to ENVARC:Sys/def_XXX.info
files to prevent the ghosting effect for these icon types.
How to add the tooltype "NoGhost" to Envarc:Sys/def_RAM.info:
1.) Load the ghosted RAM: icon with Icon->Information,
2.) Change the type from "Disk" or "Volume" into "Drawer",
3.) Add the tooltype "NoGhost" and then save the icon,
4.) Adjust RAM: window position, size, attributes and fix it,
5.) Finally, copy RAM:disk.info to ENVARC:Sys/def_RAM.info.
The library has a color reduction routine for PNG and OS4 ARGB
icons which is based on 15 bits for the first 100 colors now.
The comparison is done with less bits step by step when more
colors are required. The resulting quality is close to HiColor.
The color reduction from truecolor to the OS 3.5 format has
been improved a little. This should make color banding effects
less visible on low resolution screens. This is simply done by
pushing the RGB level of every second pixel just a bit higher.
All my efforts to use some simple dithering code for spreading
the color error could not beat the results of this method. ;-)
The cache for the screens colortable is built just once after
booting and will be updated only if the number of shared pens
has changed. The colormapping and the bitplanes for the second
image of any icon won't be done before the icons are selected.
A workaround for the DOpus5 problem to open disk drive windows
without real icons when the deficon was not of the type disk.
DOpus5 always tried to do this by itself, but it did not work
when DOpus5 had to deal with a project or tool icon as source.
Further, a completely new approach makes the icon loading with
DOpus5 a lot faster. Instead of delaying the colormapping, it
is not done at all on Hi/TrueColor screens anymore when you
disable it with the command DOnoColorMapping in your startup-
sequence. In order to get the real images while dragging the
icons around, you have to enable "Use Custom Drag Routines"
in the DOpus5 settings. But the icon loading is already much
faster without the optional command DOnoColorMapping and also
on AGA screens you can see some small speed improvements, too.
Icon.library has two new shell commands "IconUpScaling" and
"IconDownScaling". You can use them at runtime to enlarge the
icon images to 150 % or to reduce them to 66 % of their width
and height. This works with all PNG, OS 3.5 and OS 4 icons,
but not with NewIcons or oldstyle planar icons. NewIcons can
be converted, of course. Calling one of the new commands for
a second time switches the scaling off again. Please, don't
get confused when saving scaled icons to disk, because they
are updated and scaled again immediately. Switch the scaling
off after writing is done and then reopen the window. Try it.
The upscaling can be reverted to the original by downscaling.
This icon.library won't waste ChipMem for any Workbench icons.
A new space optimization routine for writing is included now.
It's always activated, regardless of the option settings, and
it rebuilds the colortables from scratch closing possible gaps
and avoiding multiple entries with the same RGB values. The
new and shorter data compression code should also be faster.
The icon images are now always compressed, but the RGB color
tables on the other side will not be compressed. It's faster.
This icon.library can also be used without conflicts on AfA_OS
since release 4.7. But AfA_OS has its own Icon_Lib.exe and will
do most of the icon drawing itself if loaded from AfA_OS_LIBS:.
AROS 68k systems are also supported with a fix for AllocList.
Please, install LoadModule LIBS:icon.library before SetPatch.
DOpus Magellan II can be used with the lack of some features.

Installation:
~~~~~~~~~~~~
On OS 3.5+ just copy icon.library_68020 to LIBS:icon.library.
The icon.library_lined may be faster on some Amithlon systems.
The 68000 version has no support for all that needs an 68020+.
Of course, it's required to load the icon.library into memory
if you want to use it with AmigaOS 3.0/3.1. This can be done
either with LoadModule, LoadResident or by using a custom ROM.
If you don't want to load the icon.library resident and want
to avoid a reboot, you could try out RemLib from Thomas Rapp.
So, you don't need any files from OS 3.5+ or Scalos anymore.
There is just one limitation: the OLD workbench.library will
not reload the icons after a screenmode change and thus the
OS 3.5 colors will not be remapped then. This needs a reboot.
Please put SwazInfo into WBStartup to replace WB-Information.
How to use this with AmigaOS 3.0 already is shown on the disk
image IconDemoADF http://eab.abime.net/showthread.php?t=64079
LoadModule may need the options NOMEMFKICK and IGNOREVERIFY.
If you don't have SetPatch v44 or cannot use LoadModule on a
68000 system then you could load the iconlib (and wblib) by:
Version >NIL: icon.library 46
If WARN
If EXISTS LIBS:workbench.library
LoadResident >NIL: LIBS:workbench.library
EndIf
LoadResident >NIL: LIBS:icon.library REBOOT
EndIf
SetPatch QUIET
If you have SetPatch v44 installed then don't load the wblib
or iconlib with LoadResident or LoadModule. It wastes memory.
Added an installation guide for OS 3.9, AGA and FBlit written
by Wizardry and Steamworks as PDF file into ThirdParty/FBlit.
=> http://grimore.org/amiga/os3.9/reduce_chip_ram_consumption
Other commands:
~~~~~~~~~~~~~~
The library will prefer to use FastMem when FBlit is detected.
There are some special shell commands for OS 3.0/3.1 users in
this package: IconFramesON, AllFramesOff and IconsToFastMem.
Systems with workbench.library v44+ can now enable the frames
for old planar icons only with PlanarFrames1/2/3. AllFramesOff
replaces the older command IconFramesOff (delete that please).
The number at the end of PlanarFrames1-3 sets the frame size.
Changing the settings in Prefs/Workbench will keep this option
alive. So you can easily select another frame size for planar
icons only if one of the supplied instructions PlanarFrames1-3
is called in your startup-sequence above the IPrefs line.
A faster colormapping mode is now optional available and can
be enabled by setting icon quality to bad in Prefs/Workbench.
Without OS 3.5+ you can add the instruction FastColors below
IPrefs in your startup-sequence. Works with a 512 byte cache.
I would recommend to call FastColors on all standard Amigas.
You could also boost the icon loading by converting PNG icons
via position SnapShot and saving all OS4 icons with WB-info.
IconsTo24BitDmaMem can be used on systems with 16-bit memory
to save the faster 32-bit memory for your real applications.
To make this possible just call IconsTo24BitDmaMem from s-s.
To enable the outline text call OutlineIconText before LoadWB.
For shadow text call ShadowIconText from the startup-sequence.
In Prefs/Fonts you should set the text and the field color for
the text background and then switch back into text only mode.
An other new instruction is GrayscaleOnOff which can be used
to render the icons in shades of gray only instead of color.
It can be enabled in Prefs/Workbench by setting icon quality
to bad like it's done for the faster colormapping. Both can't
be combined at the same time. Call the command before LoadWB.
WB 3.0/3.1 users need 2 calls: GrayscaleOnOff and FastColors.
If you start shadow/outline text or grayscale at runtime then
please update your icons and call WB-Reset from the tools menu.
The instruction "InvertGhostingMask" for the startup-sequence
can avoid the disappearing of ghosted deficons while dragging
them on the Workbench. It's a fix for a shifted dragging mask.
As a bonus, the command FixCGX_ReadPixelArray is supplied for
users of CGX software to solve problems with other programs
caused by a ReadPixelArray() bug. Icon.library won't need it.
ThirdParty:
~~~~~~~~~~
DaxB has written the script "OpenWin.rexx" as a benchmark for
for opening and displaying a window filled with many icons.
I've also included a modified version of Rebel's palette with
16 colors which can be setup by copying FullPalette.prefs into
Envarc:Sys and calling C:FPPrefs from the S:startup-sequence.
This gives a much better balanced color mapping in many cases.
An Envarc:FBlit.cfg for WB 3.1 and 1 for WB 3.5+ are supplied.
And finally, a recompiled version for WB 3.0+ and 68000 CPUs
of Stephan Rupprecht's excellent CopyIcon tool is also added.
Distribution:
~~~~~~~~~~~~
This program is freeware. I don't give any warranties. You are
