// CHANGELOG
|

// (minor and older changes stripped away, please see git history for details)
|
||||
// 2023/11/13: added support for ImFontConfig::RasterizationDensity field for scaling render density without scaling metrics.
|
||||
// 2023/08/01: added support for SVG fonts, enable by using '#define IMGUI_ENABLE_FREETYPE_LUNASVG' (#6591)
|
||||
// 2023/01/04: fixed a packing issue which in some occurrences would prevent large amount of glyphs from being packed correctly.
|
||||
// 2021/08/23: fixed crash when FT_Render_Glyph() fails to render a glyph and returns NULL.
|
||||
// 2021/03/05: added ImGuiFreeTypeBuilderFlags_Bitmap to load bitmap glyphs.
|
||||
// 2021/03/02: set 'atlas->TexPixelsUseColors = true' to help some backends with deciding of a prefered texture format.
|
||||
// 2021/01/28: added support for color-layered glyphs via ImGuiFreeTypeBuilderFlags_LoadColor (require Freetype 2.10+).
|
||||
// 2021/01/26: simplified integration by using '#define IMGUI_ENABLE_FREETYPE'. renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. removed ImGuiFreeType::BuildFontAtlas().
|
||||
// 2020/06/04: fix for rare case where FT_Get_Char_Index() succeed but FT_Load_Glyph() fails.
|
||||
// 2019/02/09: added RasterizerFlags::Monochrome flag to disable font anti-aliasing (combine with ::MonoHinting for best results!)
|
||||
// 2019/01/15: added support for imgui allocators + added FreeType only override function SetAllocatorFunctions().
|
||||
// 2019/01/10: re-factored to match big update in STB builder. fixed texture height waste. fixed redundant glyphs when merging. support for glyph padding.
|
||||
// 2018/06/08: added support for ImFontConfig::GlyphMinAdvanceX, GlyphMaxAdvanceX.
|
||||
// 2018/02/04: moved to main imgui repository (away from http://www.github.com/ocornut/imgui_club)
|
||||
// 2018/01/22: fix for addition of ImFontAtlas::TexUvscale member.
|
||||
// 2017/10/22: minor inconsequential change to match change in master (removed an unnecessary statement).
|
||||
// 2017/09/26: fixes for imgui internal changes.
|
||||
// 2017/08/26: cleanup, optimizations, support for ImFontConfig::RasterizerFlags, ImFontConfig::RasterizerMultiply.
|
||||
// 2017/08/16: imported from https://github.com/Vuhdo/imgui_freetype into http://www.github.com/ocornut/imgui_club, updated for latest changes in ImFontAtlas, minor tweaks.
|
||||
|
||||
// About Gamma Correct Blending:
|
||||
// - FreeType assumes blending in linear space rather than gamma space.
|
||||
// - See https://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html#FT_Render_Glyph
|
||||
// - For correct results you need to be using sRGB and convert to linear space in the pixel shader output.
|
||||
// - The default dear imgui styles will be impacted by this change (alpha values will need tweaking).
|
||||
|
||||
// FIXME: cfg.OversampleH, OversampleV are not supported (but perhaps not so necessary with this rasterizer).
