From a4c4566b6d51a0bd60133e1e1a7fcc19e8fcba9e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Dominik=20R=C3=B6ttsches?= Date: Thu, 19 May 2022 06:30:47 +0200 Subject: [PATCH] [truetype, snft] Add service methods for `DeltaSetIdxMap` and `VarStore`. This will be needed for 'COLR' v1 variation support. * src/truetype/ttgxvar.h (GX_ItemVarData, GX_AxisCoords, GX_VarRegion, GX_VarItemStore, GX_DeltaSetIdxMap): Move structures to... * include/freetype/internal/ftmmtypes.h: ... this new file. * include/freetype/internal/service/svmm.h (MultiMasters): Include `ftmmtypes.h`. (FT_Var_Load_Delta_Set_Idx_Map_Func, FT_Var_Load_Item_Var_Store_Func, FT_Var_Get_Item_Delta_Func, FT_Var_Done_Item_Var_Store_Func, FT_Var_Done_Delta_Set_Idx_Map_Func): New function typedefs. (MultiMasters): Add them. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/cff/cffdrivr.c (cff_load_item_variation_store, cff_load_delta_set_index_mapping, cff_get_item_delta, cff_done_item_variation_store, cff_done_delta_set_index_map): New wrapper methods calling into mm service. (cff_service_multi_masters): Updated. * src/truetype/ttgxvar.c (ft_var_load_item_variation_store, ft_var_load_delta_set_index_mapping, ft_var_get_item_delta, ft_var_done_item_variation_store, ft_var_done_delta_set_index_map): Renamed to ... (tt_var_load_item_variation_store, tt_var_load_delta_set_index_mapping, tt_var_get_item_delta, tt_var_done_item_variation_store, tt_var_done_delta_set_index_map): ... this for consistency. Mark them as non-static. * src/truetype/ttgxvar.h: Add corresponding prototypes. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. * src/type1/t1driver.c (t1_service_multi_masters): Updated. --- include/freetype/internal/ftmmtypes.h | 83 +++++++++++++++ include/freetype/internal/services/svmm.h | 122 +++++++++++++++------- src/cff/cffdrivr.c | 109 ++++++++++++++++--- src/truetype/ttdriver.c | 41 +++++--- src/truetype/ttgxvar.c | 50 ++++----- src/truetype/ttgxvar.h | 79 +++++--------- src/type1/t1driver.c | 37 ++++--- 7 files changed, 365 insertions(+), 156 deletions(-) create mode 100644 include/freetype/internal/ftmmtypes.h diff --git a/include/freetype/internal/ftmmtypes.h b/include/freetype/internal/ftmmtypes.h new file mode 100644 index 000000000..74706bedb --- /dev/null +++ b/include/freetype/internal/ftmmtypes.h @@ -0,0 +1,83 @@ +/**************************************************************************** + * + * ftmmtypes.h + * + * OpenType Variations type definitions for internal use + * with the multi-masters service (specification). + * + * Copyright (C) 2022 by + * David Turner, Robert Wilhelm, Werner Lemberg, George Williams, and + * Dominik Röttsches. + * + * This file is part of the FreeType project, and may only be used, + * modified, and distributed under the terms of the FreeType project + * license, LICENSE.TXT.
