- include the ' ' char that doesn't have a bounding box but need to be
included for the advance_x
- Fix an off by one in rendering where the last pixel was missing
Initially the character map is ordered by glyph index. Maintain that order for glyph embedding, so that we can safely collect() the bitmaps. Just before creating the final BitmapFont data structure, sort by code point for fast lookups at run-time.
Slintpad uses URLs to images. Do not fail when we "embed"
those so that we find the list of resources on the Documents
later.
This fixes image loading in slintpad again.
This removes a lot of allocations and speeds up the compiler step
a bit. Sadly, this patch is very invasive as it touches a lot of
files. That said, each individual hunk is pretty trivial.
For a non-trivial real-world example, the impact is significant,
we get rid of ~29% of all allocations and improve the runtime by
about 4.8% (measured until the viewer loop would start).
Before:
```
Benchmark 1: ./target/release/slint-viewer ../slint-perf/app.slint
Time (mean ± σ): 664.2 ms ± 6.7 ms [User: 589.2 ms, System: 74.0 ms]
Range (min … max): 659.0 ms … 682.4 ms 10 runs
allocations: 4886888
temporary allocations: 857508
```
After:
```
Benchmark 1: ./target/release/slint-viewer ../slint-perf/app.slint
Time (mean ± σ): 639.5 ms ± 17.8 ms [User: 556.9 ms, System: 76.2 ms]
Range (min … max): 621.4 ms … 666.5 ms 10 runs
allocations: 3544318
temporary allocations: 495685
```
... which will list all resources that are not going to get embedded
as `None` in the Document's `embedded_file_reosurces`.
The idea is to use that field to find all used resources in the
live preview so that we know what we can watch.
The struct held provides access to the design metrics of the font scaled
to the font pixel size used by the element.
ChangeLog: Slint Language: Added font-metrics property to `Text` and `TextInput`.
Closes#6047
If the property was not used, it was optimized out and the compiler
would panic
Fixes#6331
ChangeLog: compiler: Fix changed callback of an unused property
This is consistant so that `width: 100%` is the same as `width: parent.width`
This basically revert the previous commit that was just working around
the debug_assert to actually fix the behavior
ChangeLog: width and height expressed in `%` unit for an element in a
Flickable now refer to the size of the Flickable instead of that of
the viewport
The viewport of a flickable is of ElementType::Native, and `lookup_property`
don't query the builtin reserved properties in that case.
This commit fix the assert by allowing Type::Invalid as well.
Fixes#4163
We need to give unique name to optimized item as well, otherwise the
properties ends up the same.
Also fix the optimized element and timer when inlining
Fixes#5977Fixes#5976
Last commit uncovered some bug in which the second phase of inlining
tries to inline children in the wrong place
(This usually inlines zero children as it was already done in the first
phase, but we still assert that the location is right)
The test's build.rs invokes the compiler repeatedly with a configuration that enables font embedding. Instead of loading the same font with fontdue repeatedly (slow), store the loaded fonts in a hash table for re-use.
This should not have any impact on single file compilations, but it helps with the screenshot driver test dramatically, bringing down the time of
touch tests/screenshots/build.rs
cargo build -p test-driver-screenshots
on my xps13 linux from 1m26s to 15s.
Commit 3764312561 accidentally chained filter_map so that the list of default (fallback) fonts was empty. That resulted in
a simple hello world (with no custom fonts) embedding no font at all and causing a run-time error.
Instead of replacing the existing x/y properties with "invisible" ones, let's just keep those that we have and merely zero out the geometry x/y.
This has the bonus that access to x/y within the PopupWindow will provide the right value, i.e.
popup := PopupWindow {
x: 42px;
Text { text: popup.text / 1px; }
}
will show "42" instead of zero.
Since x/y are now merely referenced via the NamedReferences in PopupWindow, this patch also fixes the property materialization pass to use
visit_all_named_references(component) to also visit the x/y named refs,
instead of visit_all_named_references_in_element() that skips them.
