2022-09-07Fix length check in XftTextExtents*.Adam Sampson1-5/+5
Commit 06a3c0ab6520e368ac936cb1ef172f19957db0fa added length checks of the form "if (len <= 0) return;" to various Xft functions. However, while rendering an empty string is equivalent to doing nothing, asking for the extents of an empty string isn't -- it still needs to fill in the extents structure. This broke text rendering in some applications (e.g. xpdf's Motif GUI). Check for len < 0 in XftTextExtents* instead.

2022-07-09Add support for BGRA glyphs display and scalingMaxime Coste4-30/+293
Display is done using an XRender Picture, as XRender glyphs are incompatible with BGRA rendering due to their use of the glyph bitmap as a mask. Scaling is done by averaging all relevant pixel, which gives much better result than nearest pixel sampling while staying simple enough and not too computationally expensive. This enables color emoji rendering support. Fixes: #6 Signed-off-by: Maxime Coste <mawww@kakoune.org> Signed-off-by: Thomas E. Dickey <dickey@invisible-island.net>

The linear search used for randomly selecting a glyph to discard is inefficient. This commit provides for a doubly-linked list which could be maintained by the library to quickly discard the least recently used glyph. Signed-off-by: Thomas E. Dickey <dickey@invisible-island.net>

This fontconfig function has been deprecated and no longer does anything. Signed-off-by: Keith Packard <keithp@keithp.com>
2020-04-03Skip 'render' pattern elements with invalid typeKeith Packard1-0/+9
Fontconfig no longer supports the FcNameRegisterObjectTypes API, which means that any Xft custom fields cannot be specified in a fontconfig name as those will always be set to FcTypeUnknown in the pattern. The only one of those we care about is XFT_RENDER, which was used to disable the Render extension, something most apps probably don't need to support in names anyways. Allow the call requesting this value to return FcResultTypeMismatch and pretend that XFT_RENDER is missing from the pattern. Signed-off-by: Keith Packard <keithp@keithp.com>
