From 5c7f11f1cdda1c7ac89ecf4c21371f5628ee158d Mon Sep 17 00:00:00 2001 From: Andreas Kling Date: Mon, 14 Feb 2022 17:39:56 +0100 Subject: [PATCH] LibGfx/PNG: Collect tRNS (transparency chunk) info for all color types The tRNS metadata is valid for color types 0, 2 and 3, so let's collect it in each of those cases. This ensures that we produce a bitmap with an alpha channel if needed. --- Userland/Libraries/LibGfx/PNGLoader.cpp | 2 ++ 1 file changed, 2 insertions(+) diff --git a/Userland/Libraries/LibGfx/PNGLoader.cpp b/Userland/Libraries/LibGfx/PNGLoader.cpp index 4496c66805..8d723d4768 100644 --- a/Userland/Libraries/LibGfx/PNGLoader.cpp +++ b/Userland/Libraries/LibGfx/PNGLoader.cpp @@ -834,6 +834,8 @@ static bool process_PLTE(ReadonlyBytes data, PNGLoadingContext& context) static bool process_tRNS(ReadonlyBytes data, PNGLoadingContext& context) { switch (context.color_type) { + case 0: + case 2: case 3: context.palette_transparency_data.append(data.data(), data.size()); break;
