Following 2 months of work, the display and text rendering code has been
|
|||
|
|
replaced. Due to the magnitude of the change there may still be bugs, so
|
|||
|
|
please report them in the usual way.
|
|||
|
|
|
|||
|
|
These changed allow a number of significant new features to become
|
|||
|
|
available:
|
|||
|
|
|
|||
|
|
- Text over video now works correctly.
|
|||
|
|
- Changeable image and video backgrounds now have a proper start and
|
|||
|
|
finish.
|
|||
|
|
- Text enhancements are now available like colours and styles (bold,
|
|||
|
|
italic, etc).
|
|||
|
|
- Spell checker for songs and custom slides.
|
|||
|
|
|
|||
|
|
Unfortunately we've had to remove two theme features as they are no
|
|||
|
|
longer possible: transparent backgrounds, which was an early attempt to
|
|||
|
|
implement text over video, and indentation for line wrapping. Any
|
|||
|
|
transparent themes will automatically be converted to a black
|
|||
|
|
background.
|
|||
|
|
|
|||
|
|
Also note that themes may now display slightly differently as we are
|
|||
|
|
using a different display technology.
|
|||
|
|
|
|||
|
|
To access the new text enhancements, edit either a song or a custom
|
|||
|
|
slide and you'll see a new menu has been added to the right-click
|
|||
|
|
context menu of the edit box. This will allow tags to be inserted as a
|
|||
|
|
pair or wrapped round selected text. We will no doubt implement a nice
|
|||
|
|
WYSIWYG editor in a future release. Eventually we'll even allow the user
|
|||
|
|
to define their own tags, so that they can add styles to their slides.
|
|||
|
|
|
|||
|
|
From a developer's point of view to code is now much simpler and easier
|
|||
|
|
to maintain going forward. The new code is based on a web browser so
|
|||
|
|
HTML tags now can be added to text for display. Tags are implemented
|
|||
|
|
using a non-HTML tagging mechanism, so that it is easier to work with
|
|||
|
|
the tags and the text.
|
|||
|
|
|
|||
|
|
As an additional bonus, I have added a spellcheck to the songs and
|
|||
|
|
custom editors. It makes use of the PyEnchant libraries, so Linux users
|
|||
|
|
will need to add "python-enchant" (Fedora and Ubuntu) from their code
|
|||
|
|
repositories, and Windows users will have to download the library
|
|||
|
|
from http://www.rfk.id.au/software/pyenchant/download.html. The builds
|
|||
|
|
will include this library automatically.
|
|||
|
|
|
|||

The screenshot you see here of the development team's favourite song is
|
|||
|
|
an example of what we can achieve.
