Some classes use Font::get_char_size directly and not only for
autowrapping. RichTextLabel is one such example. So this commit
reverts aa8561d (PR #17504) and instead ceils character width within
Label. This makes sure Label autowraps correctly while not affecting
other Font clients.
Fixes#18835.
Fixes#15787.
The issue occurred when two (or more) separate DynamicFont instances
used the same DynamicFontAtSize instance due to having equal
properties. The first instance updated its data_at_size and emitted
"changed" signal, but the second did not because it considered the
data_at_size to be up to date, even though it has just been updated.
- Implement outlines based on FreeType Stroker API. This allows
artifact-free results, similar to what you will see in Web or any text
editing tools. Outline is a part of DynamicFont rather than Label,
because outlines have to be baked into the font's atlas. Font has a
default outline_color and a Label can specify font_outline_modulator
that will be multiplied with the Font's color to get the final result.
- draw_char now has to be called twice to fully render a text - first
with p_outline == true for each character and then with
p_outline == false for each character.
- Number of draw-calls is reduced from 5 to 2 per outlined character.
- Overall cleanup of DynamicFont code, extracted duplicated code pieces
into separate methods.
- The change is backward-compatible - Labels still have outline
properties that work exactly as they worked before.
Closes#16279.
-Missing Icons
-Missing freezing option (for baking light and faster load)
-Missing a way to export from Godot (GLTF2?)
-Probably buggy (may freeze editor, can be worked around easily, but let me know if this happens so it's easier to catch bugs)
Happy testing!
Since create_outline can only make outline for PRIMITIVE_TRIANGLES,
when QuadMesh (which is PRIMITIVE_TRIANGLE_FAN) is used to create
outline, will leave `arrays` empty, and crash when it is being indexed
for "indices" subarray.
This PR shows error when there's only one surface and it is not
TRIANGLES. Also prevent the crash if it has more than one surface
and none of them are TRIANGLES (and any other cases that could leave
`arrays` empty) by checking the size of `arrays` == 8 before indexing
it, since the method seems to expect `arrays` to be of that size.
