- Break up long sequences of visualization images in exported HTML
to avoid horizontal scrolling. Lines don't fold in "pre" mode,
and switching out of "pre" is ugly, so we just break at an
arbitrary point.
- Use a slightly different filename for animated GIFs.
- When moving items up/down in the visualization set editor or
bitmap animation editor, scroll the datagrid to keep the selected
item in view.
- Fix a wayward assert.
Visualization animations are now exported as animated GIFs. The
Windows stuff is a bit lame so I threw together some code that
stitches a bunch of GIFs together.
The GIF doesn't quite match the preview, because the preview scales
the individual frames, while the animated GIF uses the largest frame
as the size and is then scaled based on that. Animating frames of
differing sizes together is bound to be trouble anyway, so I'm not
sure how much to fret over this.
We now store Visualizations, VisualizationAnimations, and
VisualizationSets as three separate lists linked by tag strings.
WARNING: this breaks existing projects with visualizations. The
test projects have been updated.
The UI was moving items from the source list to the animation list,
but there's no reason why the same thing can't appear more than once.
You can no longer hit "Add" repeatedly to add multiple consecutive
items, but you can now multi-select in the source list to add several
things at once.
Bitmap animations are composed of a sequence of other visualizations.
This is all well and good until a visualization is deleted, at which
point all animations in all sets in the entire project have to be
checked and potentially changed, and perhaps even removed (if all of
the animation's members have been removed). This turns out to be
kind of annoying to deal with, but it's better to deal with it in
code than force the user to manually update broken animations.
This change adds thumbnails for the animations, currently generated
by offscreen composition. This approach doesn't work quite right.
This adds a new class and a rough GUI for the editor. Animated
visualizations take a collection of bitmaps and display them in
sequence. (This will eventually become an animated GIF.)
Fixed the issue where changes to tags in the set currently being
edited weren't visible to the tag uniqueness check when editing other
items in the same set.
