The median filter replaces a pixel with the median of all pixels
(usually grey value is used) in a square neighborhood. This is a
standard image processing filter used for denoising, as despite its
simplicity it can e.g. retain edges quite well.
The first implementation is quite inefficient mostly to environmental
constraints. Due to how images are passed to the processing function,
two unnecessary copies happen. And because there's no fast sorting
algorithm for small arrays (insertion sort) yet, quick sort needs to be
used which is quite slow on this scale.
This makes modifications in FontEditor more visible, both so you know
what you've changed, and for taking a handy "here's what's changed"
screenshot for a font PR. :^)
The background color for new glyphs is green, modified glyphs is blue,
and deleted glyphs is red. The changes persist until you load a new
font file, so you can continue saving your work as you go and still be
able to take a convenient screenshot at the end.
I didn't feel like this one use was enough to add 3 new color roles to
themes, so to make this look decent on dark themes, it detects if the
theme is marked as dark, and uses darker colors for the highlights
which look nice with a light text color.
If absolutely positioned divs do not have a fixed position, then their
position must be calculated based off of the position of their parent
and their siblings.
Factor out the code that computes the vertical position of a Box with
respect to its siblings so that it can be used when computing the
absolutely positioned divs as well.
The tooltip window didn't resize when setting a shorter text, or moving
to a widget with shorter text, so it had extra space on the sides.
Fix by allowing the window to resize without obeying the minimum size
of the (previous) tooltip.
Previously you had to open Display Settings and navigate to the
"Workspaces" tab in order to edit workspace settings. This patch adds a
context menu shortcut to the same place.
These allow you to specify the point were the gradient transitions
from one color to the next (without a transition hint the transition
occurs at the point 50% of the way between the two colors).
There is a little bit of guesswork in this implementation as the
specification left out how hints work with the color stop fixup,
though it appears that they are treated the same as color stops.
Menu and Window animations can now be disabled and the geometry
overlay made conditional. Shadow options are dependent on the
current theme actually supplying bitmaps, but they provide a fast
way to toggle those that do without having to edit theme files.
Effects tab provides the UI for setting SystemEffects.
DisplaySettings is getting a bit crowded and might need a re-org
at some point, but this seems like a good home for effects while
the settings mature.
SystemEffects are sent to the WindowManager through
set_system_effects() and broadcast to Desktop clients with
update_system_effects(). WindowManager is reponsible for saving,
loading and rebroadcasting effects from WindowServer.ini on
config changes.
These settings might well ultimately be factored into a dedicated
settings manager, but until then, a charitable interpretation of
Desktop::the() as the desktop environment will suffice.
Previously, during a m_might_drag mouse_up event, we were updating
the selection directly, which caused the selection to be accurate
but the location of the cursor index to be stale/incorrect. The
side effect of this is then future events may point to the wrong
index.
Instead, call the set_cursor function with SelectionUpdate::Set,
which handles both updating the cursor index as well as the
selection index.
