From 4f2c5544bbbe663483544da8d15675dfce9c0f89 Mon Sep 17 00:00:00 2001 From: David Turner Date: Fri, 12 May 2000 10:19:41 +0000 Subject: [PATCH] additional changes, this time in order to pass extra parameters to font drivers when creating a new face object. The FT_Open_Args structure has been changed to simplify its use and allow generic parameters too.. --- docs/tutorial/index.html | 122 +++++++++++++-------------- include/freetype/freetype.h | 113 +++++++++++++++++++++---- include/freetype/internal/ftdriver.h | 17 ++-- src/base/ftobjs.c | 103 +++++++++++----------- src/truetype/ttdriver.c | 10 ++- src/truetype/ttobjs.c | 14 ++- src/truetype/ttobjs.h | 8 +- src/type1/t1objs.c | 10 ++- src/type1/t1objs.h | 8 +- src/type1/t1tokens.c | 2 +- src/type1z/t1objs.c | 11 ++- src/type1z/t1objs.h | 8 +- src/type1z/t1parse.c | 2 +- 13 files changed, 272 insertions(+), 156 deletions(-) diff --git a/docs/tutorial/index.html b/docs/tutorial/index.html index 8158e5069..f6413cbca 100644 --- a/docs/tutorial/index.html +++ b/docs/tutorial/index.html @@ -164,18 +164,18 @@ FreeType 2.0 Tutorial
