Decoration
Options
Functions
|
Portable Presenter has a few modules
which descibe how to decorate a slide.
Decoration describes the background (colours and images) and
foreground-colours of the slide. The defaults are influenced by the
device-type of the viewport.
All decorations share these options:
- -backgroundBounds => [ left, top, right, bottom ]
- Limits the action-space of templates.
The values specify the percentage of the screen which should be
left empty.
A percentage can be specified as '2.5%' or 0.025 .
- -backdrop => boolean
- Backdrop is a slidely shifted character behind the real character. The
use of backdrop improves the readability of text on poor displaying
hardware, as TV-screens.
You can set backdrop on for the whole slide (or show) with this option,
or use the BD tag in the
markup formatter.
- -fgcolor => color
- -bgcolor => color
- -bdcolor => color
- The
bgcolor defines the solid color of the background.
fgcolor contains the default color of the foreground
--the color of the text. bdcolor is the backdrop color.
These values overrule the device dependent defaults.
- -nestImages => [ geometry, image, ... ]
- List of images to be used in unordered-lists
(as created by a formatter)
The color and shape of the images used may change with the images on the
background and the colors for the foreground, so are defined in
this style-element.
When you specify a geometry, you can specify a list of image-names,
filenames, or
PPresenter::Image::Magick objects.
PPresenter::Image::tkPhoto objects
are not allowed, because they are already scaled on definition.
When the geometry is undef then the list can contain
image-names, filenames, and
PPresenter::Image objects. The images
will not be scaled.
See the examples on how to create and use
images.
Settings with Function-calls
Decorations contain a few settings which can not be set simply by
option-flags with a slide, but only by calling a function.
- devices => hash-of-devs,
where devs relate a name to a ref-array
with [ bgcolor, fgcolor, bdcolor, backdrop ]
- This hash defines the default colors to be used per device.
Do not change device definitions, but add new devices with
$show->find(decoration => 'SELECTED')
->addDevice(name, fg, bg, bd, backdrop);
Devices are added in front of the list, so when you add a device
specification with an existing name, the original will not be
used anymore.
Predefined values are:
device |
background colour |
foreground colour |
backdrop colour |
default backdrop |
lcd | dark blue | yellow | black | 1 (on) |
beamer | white | black | gray | 0 (off) |
printer | white | black | gray | 0 (off) |
Use `-backdrop => boolean '
to overrule the backdrop for device. To change the default colours, you
can add a new device. Do not forget to select the new device (even when
it has the same name as the selected device):
$show->find('decoration')
->addDevice(qw/lcd black white yellow 0/);
$show->select(decoration => 'lcd');
