Iconic is the ultimate icon loader and saver plugin for Hollywood. It will make
all your icon dreams come true because it can load and save a large variety of
different icon formats. Currently, the following icon formats are supported by

- AmigaOS 1.x style icons
- AmigaOS 2.x/3.x style icons
- AmigaOS 3.5 icons (aka GlowIcons)
- AmigaOS 4.0 icons
- macOS icons (*.icns format)
- MagicWB icons
- MorphOS/PowerIcons icons (PNG)
- NewIcons 
- Windows icons (*.ico format)

Of course, Iconic also supports loading and saving of the metadata found in the
Amiga icon formats like tooltypes, icon position, drawer view mode, icon type
and so on. Thanks to Hollywood 9's new support for palette images it is also
possible to load the icon palette, set a transparent pen and access the raw
palette pens used in the icon image data. Of course, Iconic doesn't only support
palette-based icon images but also icons that contain true colour images with
alpha channel. Several of the icon formats listed above also support palette and
true colour images within the same icon file and several different icon sizes
within the same icon file. All of this is supported by Iconic as well making it
the ultimate icon loader and saver plugin for Hollywood.


Iconic requires Hollywood 9.0 or better. It's also recommended to install the
JPEG 2000 plugin for Hollywood because the macOS icon format (*.icns) stores
some images in the JPEG 2000 format and Iconic will only be able to load them
if the JPEG 2000 plugin is available.

Loading icons

To activate Iconic, simply add the following line at the top of your script:

    ()REQUIRE "iconic"
Then you can load and save icons using the functions from Hollywood's icon
library. Here's how to load and show an icon:

    LoadIcon(1, "Monkey_Island.info")
    ConvertToBrush(#ICON, 1, 1)
    DisplayBrush(1, #CENTER, #CENTER)        
Note that icons can contain images in multiple sizes and color resolutions. To
find out the number of images in an icon, just query the #ATTRNUMENTRIES
attribute. The following code iterates over all images in an icon and draws

    LoadIcon(1, "explorer.ico")

    For Local k = 1 To GetAttribute(#ICON, 1, #ATTRNUMENTRIES)
        ConvertToBrush(#ICON, 1, 1, k)
        DisplayBrush(1, #CENTER, #CENTER)

Furthermore, each icon entry can also have multiple frames. For example, Amiga
icons typically contain two frames: The first frame is shown when the icon is
not selected and the second frame is shown when it is selected. To get these
different icon states, you have to query the #ATTRNUMFRAMES attribute. Here's
how to extend the code from above to draw all icon entries and frames:

    LoadIcon(1, "Drawer.info")

    For Local k = 1 To GetAttribute(#ICON, 1, #ATTRNUMENTRIES)
        For Local j = 1 To GetAttribute(#ICON, 1, #ATTRNUMFRAMES, k)
            ConvertToBrush(#ICON, 1, 1, k, j - 1)
            DisplayBrush(1, #CENTER, #CENTER)

Amiga icons can also contain metadata stored as tooltypes. To get this data,
you can use the GetIconProperties() function:

    LoadIcon(1, "Hollywood.info")
    t = GetIconProperties(1)

    For Local k = 0 To ListItems(t.ToolTypes) - 1
       DebugPrint("Item:", k, "Key:", t.ToolTypes[k].key,
           "Value:", t.ToolTypes[k].value,
           "Enabled:", t.ToolTypes[k].enabled)

GetIconProperties() also allows you to read other metadata that is stored in
Amiga icons, like the icon type, its position on the Workbench, the size of the
drawer window if the icon is a drawer icon etc.
Finally, if Iconic is activated, you can also use icons in formats supported by
the plugin with the ()APPICON preprocessor command. Thus, with Iconic installed
you could also do something like this:

    ()APPICON "my_app.ico"
It's no longer necessary to use Hollywood's custom icon format or specify the
individual icon images manually. With Iconic you can simply pass an icon in one
of the common icon formats to ()APPICON.

Saving icons

Icons can be saved using the SaveIcon() function from Hollywood's icon library.
When Iconic is active, it will register the following new icon formats for use
with SaveIcon():

- #ICNFMT_AMIGAOS: classic AmigaOS icon
- #ICNFMT_AMIGAOS35: AmigaOS 3.5 icon (GlowIcon)
- #ICNFMT_AMIGAOS40: AmigaOS 4.0 icon
- #ICNFMT_MACOS: macOS icon (*.icns format)
- #ICNFMT_NEWICON: NewIcons icon
- #ICNFMT_PNG: MorphOS/PowerIcons icon in PNG format
- #ICNFMT_WINDOWS: Windows icon (*.ico format)

For example, to save icon 1 as a classic AmigaOS icon, you could use the
following code:

    SaveIcon(1, "test.info", #ICNFMT_AMIGAOS)

Note that all icon formats have their peculiarities. For example, classic
AmigaOS icons must be palette-based and the palette isn't stored in the icon
file. So if you try to save an icon that only contains 32-bit true colour image
data with alpha channel as a classic AmigaOS icon, Iconic will render the true
colour pixel data down to 4 colours using the Workbench 1.x palette when saving
the icon. This will probably lead to rather unsatisfying results, so for 
optimal results you should make sure that the icon you are about to save
contains the pixel data exactly in the format as expected by the respective icon
format. See the next chapter for an overview of pixel data formats supported by
the individual icon formats supported by Iconic.

Some icon formats also support compression of the image and palette data. If an
icon format supports compression, Iconic will compress the image and palette
data. If you want to turn this off, set the table tag "Compression" to FALSE
when you call SaveIcon(), e.g.

    SaveIcon(1, "test.info", #ICNFMT_AMIGAOS35, {Compression = False})

To modify the metadata that is supported by AmigaOS icons, use the function
SetIconProperties() from Hollywood's icon library. See the Hollywood manual for

Icon format information

For reference, here is some information about the icon formats supported by

- AmigaOS 1.x style icons: This is a palette-based icon format which uses just
  a single image that should be in 4 colors. Note that the palette isn't stored
  in the icon itself but instead it is expected that the icon uses the standard
  Workbench 1.x colors.

- AmigaOS 2.x/3.x style icons: The same as AmigaOS 1.x style icons except that
  icons have two states now (normal and selected). Also, they support some
  additional metadata like tooltypes. Image data should be 4 colors and use the
  standard Workbench 2.x colors.
- AmigaOS 3.5 icons (aka GlowIcons): This is a palette-based icon format and
  in contrast to classic AmigaOS icons, the palette is stored inside the icon
  so that icons appear in the correct colors independent of the Workbench's
  palette. GlowIcons support a transparent pen, the maximum icon size is 256x256
  pixels and the maximum color depth is 8-bit, i.e. 256 colors. GlowIcons also
  contain a 4-color fallback icon that will be shown on Amiga systems that don't
  support GlowIcons. Icons have two different states (normal and selected). 
  Image and palette data can be stored with or without compression.
- AmigaOS 4.0 icons: This icon format is used on AmigaOS 4.x and supports true
  colour icons with alpha channel (32-bit). The maximum size is 256x256 pixels.
  AmigaOS 4.0 icons also contain a 4-color fallback icon that will be shown on
  classic Amiga systems that don't support AmigaOS 4.0 icons. Icon have two
  different states (normal and selected).

- macOS icons (*.icns format): Images inside the icon can't use arbitrary sizes
  like in the Amiga icon formats but can only use the following fixed pixel
  sizes: 16x16, 32x32, 48x48, 64x64, 128x128, 256x256, 512x512, 1024x1024. Sizes
  bigger than 128x128 pixels must only contain 32-bit alpha channel true colour
  images. Smaller sizes also support palette images but typically can contain
  32-bit true colour data as well. Image data can be stored with or without
- MagicWB icons: These are like AmigaOS 2.x/3.x icons but use 8 colors and a
  special palette known as the MagicWB palette. Like with classic AmigaOS icons
  the palette isn't stored inside the icon file so Iconic will treat all icons
  that use 8 colors as MagicWB icons.

- MorphOS/PowerIcons icons (PNG): This is an Amiga icon format based on the PNG
  format. It is used on MorphOS and on classic systems using the PowerIcons
  patch. Image data can be of an arbitrary size and must use 32-bit true colour
  pixel data with alpha channel. Icons only contain one image and one state.
- NewIcons: This is a palette-based icon format and in contrast to classic
  AmigaOS icons, the palette is stored inside the icon so that icons appear in
  the correct colors independent of the Workbench's palette. NewIcons support a
  transparent pen, the maximum icon size is 93x93 pixels and the maximum color
  depth is 8-bit, i.e. 256 colors. NewIcons also contain a 4-color fallback icon
  that will be shown on Amiga systems that don't support NewIcons. Icons have
  two different states (normal and selected).
- Windows icons (*.ico format): Images inside the icon can be up to 256x256
  pixels. They can use image data that is palette-based or 32-bit true colour
  image data that contains an alpha channel. Image data can be stored with or
  without compression.
