* WIP: swrenderer: use fixed point for the pixmap font coordinate
* swrenderer: signed distance field: move the glyph to the middle
* swrenderer: round the advance instead of truncating it in distance field
* swrenderer: actually align the gplyph on the sub-pixel precision
sub-pixel within the source.
* swrenderer: adapt the threshold for signed distance field
sqrt(2) is the distance to the diagonal, seems like this gives sharper fonts
* Fix bug in the elision, and re-upload the screenshort
the screenshot changed because the afvanced is now rounded intead of
truncated
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
Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
In the screenshot tests this works by setting SLINT_DEFAULT_FONT to
pointer to a directory, instead of a file. We then load all fonts in
that directory and consider their families the default unless a family
is specified. This way for "Noto Sans" a regular as well as an italic
version is registered in fontdb and returned in the list of font
fallback ids. embed_glyphs in the compiler then embeds those variants
and we find them at run-time.
The code was mixing logical and physical sizes, causing glyphs being
doubly scaled down. Instead, this patch introduces:
* Physical* and Logical* euclid length/size/rect aliases
* some extraction traits for getting the scalars in rects/sizes as lengths (until euclid has them
built-in)
* wrapper traits/types for safely extracting the physical font metrics the
compiler generates (i16)
* Fix a bug in the text height calculation where we failed to take the
descent into account
Enable with `SLINT_EMBED_GLYPHS=1` and select sizes like
`SLINT_FONT_SIZES=12,16`
This change just puts the data structures in place, rasterizes a fixed
subset, embeds that into the rust generated code and calls a backend
function for registering the font that is unimplemented.
