From c3f0d8a4612f25ac3b728d8335c13dc543254be2 Mon Sep 17 00:00:00 2001 From: Sebastian Rasmussen Date: Tue, 11 Oct 2016 22:39:08 +0800 Subject: Drop all contexts the same way. * Handle multiple calls to fz_drop_colorspace_context() and fz_drop_font_context(). * Allow missing context in call to fz_drop_aa_context() and fz_drop_glyph_cache_context(). * Only drop font context objects when dropping the last reference. * Avoid unnecessary NULL checks. --- source/fitz/draw-edge.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'source/fitz/draw-edge.c') diff --git a/source/fitz/draw-edge.c b/source/fitz/draw-edge.c index cd6a525f..0da45331 100644 --- a/source/fitz/draw-edge.c +++ b/source/fitz/draw-edge.c @@ -53,6 +53,8 @@ void fz_copy_aa_context(fz_context *dst, fz_context *src) void fz_drop_aa_context(fz_context *ctx) { + if (!ctx) + return; #ifndef AA_BITS fz_free(ctx, ctx->aa); ctx->aa = NULL; -- cgit v1.2.3
