Re-order cairo context scaling and pango layout setup (#2337).

2025-09-26T21:57:09Z

This seems to fix problems where letters were scaled individually, but their spacing didn't change (when x scale was applied). Big thanks to user1768761 https://stackoverflow.com/questions/58528024/pangocairo-shows-cluttered-text-when-cairo-context-is-scaled

Fix cut-off subtitle shadows.

Make shadow offset proportional to the target size.

Otherwise it looks further away in the preview than in in the final DCP (if the preview is smaller).

Add dcp_pixels_to_pixels().

Return float from border_width_for_subtitle().

2025-07-08T20:11:35Z

We're already using ceil on the return value everywhere we need to, as far as I can see.

White space: render_text.cc.

Bump libdcp for raw_convert changes.

2025-01-05T11:58:13Z

raw_convert is gone, so here we use fmt::{to_string,format} instead. Other raw_converts now use fast_float.

Fix warning from pango about letter spacing not being an integer.

Render subtitles using show_in_cairo_context() instead of add_to_cairo_context().

2024-05-30T17:59:06Z

This helps with #2813 and should fix #2474. We started using add_to_cairo_context() again in 72c3a5f0f32f553a1f8abee2494f31d29b976383 because the rendering looked better. However colour changes within lines cannot easily be rendered using add_to_cairo_context() it seems, as the text is just added as a path and then you can stroke/fill it with a single colour. I hope that this change, which reverts 72c3a5 but also adds some calls to enable hinting and use better anti-aliasing, looks OK. I looked at some white-on-black subs close-up and the hinting seems to help.
