From 14763ed3c68bcf2a21e2494bc0d8920cc0ac1f62 Mon Sep 17 00:00:00 2001 From: "madmaxoft@gmail.com" Date: Tue, 22 Jan 2013 06:49:14 +0000 Subject: Added new statistics module to AnvilStats - cHeightMap. This paints the heightmap of each region file into a separate BMP file. git-svn-id: http://mc-server.googlecode.com/svn/trunk@1163 0a769ca7-a7f5-676a-18bf-c427514a06d6 --- AnvilStats/HeightMap.cpp | 265 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 265 insertions(+) create mode 100644 AnvilStats/HeightMap.cpp (limited to 'AnvilStats/HeightMap.cpp') diff --git a/AnvilStats/HeightMap.cpp b/AnvilStats/HeightMap.cpp new file mode 100644 index 000000000..9f52c2109 --- /dev/null +++ b/AnvilStats/HeightMap.cpp @@ -0,0 +1,265 @@ + +// HeightMap.cpp + +// Implements the cHeightMap class representing a cCallback descendant that draws a B&W map of heights for the world + +#include "Globals.h" +#include "HeightMap.h" + + + + +static const unsigned char g_BMPHeader[] = +{ + 0x42, 0x4D, 0x36, 0x00, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x00, 0x00, 0x00, 0x28, 0x00, + 0x00, 0x00, 0x00, 0x02, 0x00, 0x00, 0x00, 0xfe, 0xff, 0xff, 0x01, 0x00, 0x20, 0x00, 0x00, 0x00, + 0x00, 0x00, 0x00, 0x00, 0x10, 0x00, 0x13, 0x0B, 0x00, 0x00, 0x13, 0x0B, 0x00, 0x00, 0x00, 0x00, + 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 +} ; + + + + + +cHeightMap::cHeightMap(void) : + m_CurrentRegionX(0), + m_CurrentRegionZ(0), + m_IsCurrentRegionValid(false) +{ +} + + + + + +void cHeightMap::Finish(void) +{ + if (m_IsCurrentRegionValid) + { + StartNewRegion(0, 0); + } +} + + + + + +bool cHeightMap::OnNewChunk(int a_ChunkX, int a_ChunkZ) +{ + int RegionX = (a_ChunkX < 0) ?
