From 6a4fdd3f43fbbc15988781e904ab3fe40e66fec4 Mon Sep 17 00:00:00 2001 From: Michal Szczecinski Date: Mon, 22 Feb 2021 05:30:05 +0100 Subject: [PATCH] Issue 180 example (#212) * examples: Added resize_cb to Capi example. resize_cb in capi example is used to verify crash on reize described in @180 issue. * examples capi: Fixed file type from dos to unix. Use the same code style as it is used in other examples. --- src/examples/Capi.cpp | 454 ++++++++++++++++++++++++++------------------------ 1 file changed, 239 insertions(+), 215 deletions(-) diff --git a/src/examples/Capi.cpp b/src/examples/Capi.cpp index 01e95b7..1485d2e 100644 --- a/src/examples/Capi.cpp +++ b/src/examples/Capi.cpp @@ -1,215 +1,239 @@ -#include -#include - -#define WIDTH 800 -#define HEIGHT 800 - - -/************************************************************************/ -/* Capi Test Code */ -/************************************************************************/ - -static uint32_t buffer[WIDTH * HEIGHT];
